Barczak K, Droździk A, Bosiacki M, Łagocka R, Cenariu D, Uriciuc WA, Baranowska-Bosiacka I. CCL5's Role in Periodontal Disease: A Narrative Review. Int J Mol Sci 2023; 24:17332. [PMID: 38139161 PMCID: PMC10744061 DOI: 10.3390/ijms242417332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 12/02/2023] [Accepted: 12/07/2023] [Indexed: 12/24/2023] Open
Abstract
Persistent host inflammatory and immune responses to biofilm play a critical role in the mechanisms that govern soft and hard tissue destruction in periodontal disease. Among the less explored facets of these mechanisms are chemokines, including CCL5 (C-C motif chemokine ligand 5), also known as RANTES (regulated on activation, normal T cell expressed and secreted), a proinflammatory CC subfamily chemokine synthesized by T lymphocytes. Despite its importance, there is currently no comprehensive review of the role of CCL5 in periodontitis in the literature. Therefore, this paper aims to fill this gap by summarizing the existing knowledge on the involvement of CCL5 in the onset and progression of periodontitis. In addition, we aim to stimulate interest in this relatively overlooked factor among periodontitis researchers, potentially accelerating the development of drugs targeting CCL5 or its receptors. The review examines the association of CCL5 with periodontitis risk factors, including aging, cigarette smoking, diabetes, and obesity. It discusses the involvement of CCL5 in pathological processes during periodontitis, such as connective tissue and bone destruction. The data show that CCL5 expression is observed in affected gums and gingival crevicular fluid of periodontitis patients, with bacterial activity contributing significantly to this increase, but the reviewed studies of the association between CCL5 expression and periodontal disease have yielded inconclusive results. Although CCL5 has been implicated in the pathomechanism of periodontitis, a comprehensive understanding of its molecular mechanisms and significance remains elusive, hindering the development of drugs targeting this chemokine or its receptors.

J Allergy Clin Immunol 2023; 152:205-213. [PMID: 36813186 DOI: 10.1016/j.jaci.2023.01.033] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 12/16/2022] [Accepted: 01/11/2023] [Indexed: 02/23/2023]
Abstract
BACKGROUND Systemic mastocytosis (SM) is a heterogeneous group of mast cell-driven diseases diagnosed by bone marrow sampling. However, there are a limited number of available blood disease biomarkers. OBJECTIVE Our aim was to identify mast cell-derived proteins that could potentially serve as blood biomarkers for indolent and advanced forms of SM. METHODS We performed a plasma proteomics screening coupled with single-cell transcriptomic analysis in SM patients and healthy subjects. RESULTS Plasma proteomics screening identified 19 proteins upregulated in indolent disease compared to healthy, and 16 proteins in advanced disease compared to indolent. Among these, 5 proteins, CCL19, CCL23, CXCL13, IL-10, and IL-12Rβ1, were higher in indolent relative to healthy and in advanced disease compared to indolent. Single-cell RNA sequencing demonstrated that CCL23, IL-10, and IL-6 were selectively produced by mast cells. Notably, plasma CCL23 levels correlated positively with known markers of SM disease severity, namely tryptase levels, percentage bone marrow mast cell infiltration, and IL-6. CONCLUSION CCL23 is produced predominantly by mast cells in SM, and CCL23 plasma levels are associated with disease severity, correlating positively with established markers of disease burden, thus suggesting that CCL23 is a specific SM biomarker. In addition, the combination of CCL19, CCL23, CXCL13, IL-10, and IL-12Rβ1 may be useful for defining disease stage.

A Functional Polymorphism Downstream of Vitamin A Regulator Gene CYP26B1 Is Associated with Hand Osteoarthritis. Int J Mol Sci 2023; 24:ijms24033021. [PMID: 36769350 PMCID: PMC9918232 DOI: 10.3390/ijms24033021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Revised: 01/30/2023] [Accepted: 01/31/2023] [Indexed: 02/09/2023] Open
Abstract
While genetic analyses have revealed ~100 risk loci associated with osteoarthritis (OA), only eight have been linked to hand OA. Besides, these studies were performed in predominantly European and Caucasian ancestries. Here, we conducted a genome-wide association study in the Han Chinese population to identify genetic variations associated with the disease. We recruited a total of 1136 individuals (n = 420 hand OA-affected; n = 716 unaffected control subjects) of Han Chinese ancestry. We carried out genotyping using Axiom Asia Precisi on Medicine Research Array, and we employed the RegulomeDB database and RoadMap DNase I Hypersensitivity Sites annotations to further narrow down our potential candidate variants. Genetic variants identified were tested in the Geisinger's hand OA cohort selected from the Geisinger MyCode community health initiative (MyCode®). We also performed a luciferase reporter assay to confirm the potential impact of top candidate single-nucleotide polymorphisms (SNPs) on hand OA. We identified six associated SNPs (p-value = 6.76 × 10-7-7.31 × 10-6) clustered at 2p13.2 downstream of the CYP26B1 gene. The strongest association signal identified was rs883313 (p-value = 6.76 × 10-7, odds ratio (OR) = 1.76), followed by rs12713768 (p-value = 1.36 × 10-6, OR = 1.74), near or within the enhancer region closest to the CYP26B1 gene. Our findings showed that the major risk-conferring CC haplotype of SNPs rs12713768 and rs10208040 [strong linkage disequilibrium (LD); D' = 1, r2 = 0.651] drives 18.9% of enhancer expression activity. Our findings highlight that the SNP rs12713768 is associated with susceptibility to and severity of hand OA in the Han Chinese population and that the suggested retinoic acid signaling pathway may play an important role in its pathogenesis.

Macrophage-derived CCL23 upregulates expression of T-cell exhaustion markers in ovarian cancer. Br J Cancer 2022; 127:1026-1033. [PMID: 35750747 DOI: 10.1038/s41416-022-01887-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 05/16/2022] [Accepted: 06/07/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Macrophages are an important component of the tumour immune microenvironment (TME) and can promote tumour growth and metastasis. Macrophage-secreted chemokine-ligand-23 (CCL23) induces ovarian cancer cell migration via chemokine-receptor 1 (CCR1). However, the effect of CCL23 on other immune cells in the TME is unknown. METHODS CCL23 levels were measured by ELISA. The expression of surface markers in exhaustion assays was quantified by flow cytometry. Signalling pathways were identified by phosphokinase array and validated by western blot. RESULTS Ascites from patients with high-grade serous ovarian cancer (HGSC) contain high levels of CCL23. Similarly, significantly higher CCL23 levels were found in plasma from HGSC patients compared to healthy individuals. RNA-seq analysis of ovarian cancer tissues from TCGA showed that expression of CCL23 correlated with the presence of macrophages. In tissues with high levels of CCL23 and macrophage content, the fraction of CD8 + T cells expressing exhaustion markers CTLA-4 and PD-1 were significantly higher compared to low-level CCL23 tissues. In vitro, CCL23 induced upregulation of immune checkpoint proteins on CD8 + T cells, including CTLA-4, TIGIT, TIM-3 and LAG-3 via phosphorylation of GSK3β in CD8 + T cells. CONCLUSIONS Our data suggest that CCL23 produced by macrophages contributes to the immune-suppressive TME in ovarian cancer by inducing an exhausted T-cell phenotype.

C‑X‑C receptor 7 agonist acts as a C‑X‑C motif chemokine ligand 12 inhibitor to ameliorate osteoclastogenesis and bone resorption. Mol Med Rep 2022; 25:78.

Abstract
The C-X-C receptor (CXCR) 7 agonist, VUF11207, is a chemical compound that binds specifically to CXCR7, and negatively regulates C-X-C motif chemokine ligand 12 (CXCL12) and CXCR4-induced cellular events. Lipopolysaccharide (LPS) can induce inflammatory cytokines and pathological bone loss. LPS also induces expression of CXCL12, enhancing sensitivity to receptor activator of NF-κB ligand (RANKL) and tumor necrosis factor-α (TNF-α) in vivo. RANKL and TNF-α induce the differentiation of osteoclasts into osteoclast precursors and bone resorption. The current study was performed to examine the effects of a CXCR7 agonist on osteoclastogenesis and bone resorption induced by LPS in vivo. In addition, the mechanisms underlying these in vivo effects were investigated by in vitro experiments. Eight-week-old male C57BL/6J mice were subcutaneously injected over the calvariae with LPS alone or LPS and CXCR7 agonist. After sacrifice, the number of osteoclasts and the bone resorption area were measured. In vitro experiments were performed to investigate the effects of CXCL12 and CXCR7 agonist on osteoclastogenesis induced by RANKL and TNF-α. Mice injected with LPS and CXCR7 agonist showed significantly reduced osteoclastogenesis and bone resorption compared with mice injected with LPS alone. Moreover, the CXCR7 agonist inhibited CXCL12 enhancement of RANKL- and TNF-α-induced osteoclastogenesis in vitro. Thus, CXCR7 agonist inhibited LPS-induced osteoclast-associated cytokines, such as RANKL and TNF-α, as well as RANKL- and TNF-α-induced osteoclastogenesis in vitro by modulating CXCL12-mediated enhancement of osteoclastogenesis. In conclusion, CXCR7 agonist reduced CXCL12-mediated osteoclastogenesis and bone resorption.

Abstract
Oral commensal bacteria actively participate with gingival tissue to maintain healthy neutrophil surveillance and normal tissue and bone turnover processes. Disruption of this homeostatic host-bacteria relationship occurs during experimental gingivitis studies where it has been clearly established that increases in the bacterial burden increase gingival inflammation. Here, we show that experimental gingivitis resulted in three unique clinical inflammatory phenotypes (high, low, and slow) and reveal that interleukin-1β, a reported major gingivitis-associated inflammatory mediator, was not associated with clinical gingival inflammation in the slow response group. In addition, significantly higher levels of Streptococcus spp. were also unique to this group. The low clinical response group was characterized by low concentrations of host mediators, despite similar bacterial accumulation and compositional characteristics as the high clinical response group. Neutrophil and bone activation modulators were down-regulated in all response groups, revealing novel tissue and bone protective responses during gingival inflammation. These alterations in chemokine and microbial composition responses during experimental gingivitis reveal a previously uncharacterized variation in the human host response to a disruption in gingival homeostasis. Understanding this human variation in gingival inflammation may facilitate the identification of periodontitis-susceptible individuals. Overall, this study underscores the variability in host responses in the human population arising from variations in host immune profiles (low responders) and microbial community maturation (slow responders) that may impact clinical outcomes in terms of destructive inflammation.

Abstract
INTRODUCTION Bisphosphonate (BP)-related osteonecrosis of the jaw (BRONJ) is a complication of intravenous (IV) BP therapy. BP therapy locally affects the dentoalveolar area, while systemic effects are associated with parenteral/IV BP use. Despite numerous publications, the pathogenesis of BRONJ is not fully understood, as only some patients receiving IV BPs develop BRONJ. PURPOSE Can impaired bone remodeling (found in aseptic-ischemic osteonecrosis of the jaw [AIOJ], bone marrow defects [BMD], or fatty-degenerative osteonecrosis of the jaw [FDOJ]) represent a risk factor for BRONJ formation? PATIENTS AND METHODS A literature search clarified the relationship between AIOJ, BMD, FDOJ, and BRONJ, in which common characteristics related to signal cascades, pathohistology, and diagnostics are explored and compared. A case description examining non-exposed BRONJ is presented. DISCUSSION Non-exposed BRONJ variants may represent one stage in undetected BMD development, and progression to BRONJ results from BPs. CONCLUSION Unresolved wound healing at extraction sites, where wisdom teeth have been removed for example, may contribute to the pathogenesis of BRONJ. With IV BP administration, persisting AIOJ/BMD/FDOJ areas may be behind BRONJ development. Therapeutic recommendations include IV BP administration following AIOJ/BMD/FDOJ diagnosis and surgical removal of ischemic areas. BPs should not be regarded as the only cause of osteonecrosis.

Abstract
CC chemokines, a subfamily of 27 chemotactic cytokines, are a component of intercellular communication, which is crucial for the functioning of the tumor microenvironment. Although many individual chemokines have been well researched, there has been no comprehensive review presenting the role of all known human CC chemokines in the hallmarks of cancer, and this paper aims at filling this gap. The first part of this review discusses the importance of CCL1, CCL3, CCL4, CCL5, CCL18, CCL19, CCL20, CCL21, CCL25, CCL27, and CCL28 in cancer. Here, we discuss the significance of CCL2 (MCP-1), CCL7, CCL8, CCL11, CCL13, CCL14, CCL15, CCL16, CCL17, CCL22, CCL23, CCL24, and CCL26. The presentation of each chemokine includes its physiological function and then the role in tumor, including proliferation, drug resistance, migration, invasion, and organ-specific metastasis of tumor cells, as well as the effects on angiogenesis and lymphangiogenesis. We also discuss the effects of each CC chemokine on the recruitment of cancer-associated cells to the tumor niche (eosinophils, myeloid-derived suppressor cells (MDSC), tumor-associated macrophages (TAM), tumor-associated neutrophils (TAN), regulatory T cells (Treg)). On the other hand, we also present the anti-cancer properties of CC chemokines, consisting in the recruitment of tumor-infiltrating lymphocytes (TIL).

Abstract
Chemokines are a family of small proteins, subdivided by their conserved cysteine residues and common structural features. Chemokines interact with their cognate G-protein-coupled receptors to elicit downstream signals that result in cell migration, proliferation, and survival. This review presents evidence for how the various CXC and CC subfamily chemokines influence bone hemostasis by acting on osteoclasts, osteoblasts, and progenitor cells. Also discussed are the ways in which chemokines contribute to bone loss as a result of inflammatory diseases such as rheumatoid arthritis, HIV infection, and periodontal infection. Both positive and negative effects of chemokines on bone formation and bone loss are presented. In addition, the role of chemokines in altering the bone microenvironment through effects on angiogenesis and tumor invasion is discussed. Very few therapeutic agents that influence bone formation by targeting chemokines or chemokine receptors are available, although a few are currently being evaluated.

Abstract
Chemokines are secreted by a wide variety of cells; their functions are dependent on the binding to their chemokine receptors (CCRs) which induce directed chemotaxis in nearby responsive cells. Chemokines and their receptors can be induced under several different conditions. Based on data from clinical studies showing an increased expression of chemokine receptor 3 (CCR3) in circulating monocytes of human subjects with lower bone mineral density (BMD) as compared to those with high BMD, we predicted a role for CCR3 in the development of peak bone mass. We, therefore, first evaluated the expression pattern of Ccr3 in bone cells, in comparison to other CCRs, that have common ligands with CCR3. While Ccr1 and Ccr3 messenger RNA (mRNA) levels increased during both RANKL-induced osteoclast differentiation and AA-induced osteoblast differentiation, the levels of Ccr5 mRNA only increased during osteoblast differentiation. To examine if CCR3 influences osteoclast and/or osteoblast differentiation, we evaluated the consequence of blocking CCR3 function using neutralizing antibody on the expression of osteoclast and osteoblast differentiation markers. Treatment with CCR3 neutralizing antibody increased mRNA levels of Trap and cathepsin K in osteoclasts and osteocalcin in osteoblasts compared to cells treated with control IgG. Based on these in vitro findings, we next assessed the role of CCR3 in vivo by evaluating the skeletal phenotypes of Ccr3 knockout and corresponding control littermate mice. Disruption of CCR3 resulted in a significant increase in femur areal BMD at 5 and 8 weeks of age by dual-energy X-ray absorptiometry. Micro-CT analysis revealed a 25% increase in trabecular bone mass at 10 weeks of age caused by corresponding changes in trabecular number and thickness compared to wild type mice. Based on our findings, we conclude that disruption of CCR3 function favors bone mass accumulation, in part via enhancement of bone metabolism. Understanding the molecular pathways through which CCR3 acts to regulate osteoclast and osteoblast functions could lead to new therapeutic approaches to prevent inflammation-induced bone loss.

Abstract
The inflammatory and autoimmune events preceding clinical symptoms in rheumatoid arthritis (RA) and other autoimmune diseases are difficult to study in human patients. Therefore, animal models that share immunologic and clinical features with human RA, such as pristane-induced arthritis (PIA), are valuable tools for assessing the primordial events related to arthritis susceptibility. PIA-resistant HIII and susceptible LIII mice were injected i.p. with pristane, and peritoneal lavage fluid was harvested in the early (7 days) and late (35 days) preclinical phases of PIA. Chemokine and cytokine levels were measured in lavage supernatant with ELISA, peritoneal inflammatory leukocytes were immunophenotyped by flow cytometry, and gene expression was determined by qRT-PCR. Leukocyte recruitment was quantitatively and qualitatively divergent in the peritoneum of HIII and LIII mice, with an early increase of CC chemokines (CCL2/CCL3/CCL5/CCL12/CCL22) in the susceptible LIII strain. Also, cytokines such as IL-12p40, IL-23, and IL-18 were elevated in LIII mice while IL-6 was increased in HIII animals. The results show that an early peritoneal CC chemokine response is an important feature of arthritis susceptibility and defines potential biomarkers in this model.

C-X-C Motif Chemokine 12 Enhances Lipopolysaccharide-Induced Osteoclastogenesis and Bone Resorption In Vivo. Calcif Tissue Int 2018; 103:431-442.

Abstract
C-X-C motif chemokine 12 (CXCL12) belongs to the family of CXC chemokines. Lipopolysaccharide (LPS) induces inflammation-induced osteoclastogenesis and bone resorption, and in recent years, stimulatory effects of CXCL12 on bone resorption have also been reported. In the present study, we investigated the effects of CXCL12 on LPS-induced osteoclastogenesis and bone resorption. LPS was administered with or without CXCL12 onto mouse calvariae by daily subcutaneous injection. Numbers of osteoclasts and bone resorption were significantly elevated in mice co-administered LPS and CXCL12 compared with mice administered LPS alone. Moreover, receptor activator of NF-kB ligand (RANKL) and tumor necrosis factor-α (TNF-α) mRNA levels were higher in mice co-administered LPS and CXCL12 compared with mice administered LPS alone. These in vitro results confirmed a direct stimulatory effect of CXCL12 on RANKL- and TNF-α-induced osteoclastogenesis. Furthermore, TNF-α and RANKL mRNA levels were elevated in macrophages and osteoblasts, respectively, co-treated in vitro with CXCL12 and LPS, in comparison with cells treated with LPS alone. Our results suggest that CXCL12 enhances LPS-induced osteoclastogenesis and bone resorption in vivo through a combination of increasing LPS-induced TNF-α production by macrophages, increasing RANKL production by osteoblasts, and direct enhancement of osteoclastogenesis.

Abstract
CCL23, also known as myeloid progenitor inhibitory factor (MPIF)-1, macrophage inflammatory protein (MIP)-3, or CKβ8, is a member of the CC chemokine subfamily exerting its effects via CCR1 binding. By doing so, CCL23 selectively recruits resting T lymphocytes and monocytes, inhibits proliferation of myeloid progenitor cells and promotes angiogenesis. Previously, we and other groups have reported that human neutrophils are able to produce chemokines upon appropriate activation, including CCR1-binding CCL2, CCL3, and CCL4. Herein, we demonstrate that human neutrophils display the capacity to also express and release CCL23 when stimulated by R848 and, to a lesser extent, by other pro-inflammatory agonists, including LPS, Pam3CSK4, and TNFα. Notably, we show that, on a per cell basis, R848-activated neutrophils produce higher levels of CCL23 than autologous CD14+-monocytes activated under similar experimental conditions. By contrast, we found that, unlike CD14+-monocytes, neutrophils do not produce CCL23 in response to IL-4, thus indicating that they express CCL23 in a stimulus-specific fashion. Finally, we show that the production of CCL23 by R848-stimulated neutrophils is negatively modulated by IFNα, which instead enhances that of CCL2. Together, data extend our knowledge on the chemokines potentially produced by neutrophils. The ability of human neutrophils to produce CCL23 further supports the notion on the neutrophil capacity of orchestrating the recruitment of different cell types to the inflamed sites, in turn contributing to the control of the immune response.

Abstract
The inflammatory oral diseases are characterized by the persistent migration of polymorphonuclear leukocytes, monocytes, lymphocytes, plasma and mast cells, and osteoblasts and osteoclasts. In the last decade, there has been a great interest in the mediators responsible for the selective recruitment and activation of these cell types at inflammatory sites. Of these mediators, the chemokines have received particular attention in recent years. Chemokine messages are decoded by specific receptors that initiate signal transduction events, leading to a multitude of cellular responses, including chemotaxis and activation of inflammatory and bone cells. However, little is known about their role in the pathogenesis of inflammatory oral diseases. The purpose of this review is to summarize the findings regarding the role of chemokines in periapical and periodontal tissue inflammation, and the integration, into experimental models, of the information about the role of chemokines in human diseases.

Abstract
Chronic periodontitis (CP) is a prevalent pathogen-associated inflammatory disorder characterized by the destruction of tooth-supporting tissues, and linked to several systemic diseases. Both the periodontopathogen Porphyromonas gingivalis (Pg), and the genetically determined host immune response, are hypothesized to play a crucial role in this association. To identify new target genes for CP and its associated systemic diseases, we investigated the transcriptome induced by Pg in human monocytes using a genome-wide approach. Monocytes were isolated from healthy male volunteers of European origin and challenged with the Pg virulence factor LPS. Array-based gene expression analysis comprising >47,000 transcripts was performed followed by pathway analyses. Transcriptional data were validated by protein and cell surface markers. LPS Pg challenge led to the significant induction of 902 transcripts. Besides known periodontitis-associated targets, several new candidates were identified (CCL23↑, INDO↑, GBP 1/4↑, CFB↑, ISG20↑, MIR155HG↑, DHRS9↓). Moreover, various transcripts correspond to the host immune response, and have been linked to cancer, atherosclerosis and arthritis, thus highlighting the systemic impact of CP. Protein data of immunological markers validated our results. The present findings expand understanding of Pg elicited immune responses, and indicate new target genes and pathways of relevance to diagnostic and therapeutic strategies.

Abstract
The pathogenesis of periodontitis involves a complex immune/inflammatory cascade that is initiated by the bacteria of the oral biofilm that forms naturally on the teeth. The susceptibility to periodontitis appears to be determined by the host response; specifically, the magnitude of the inflammatory response and the differential activation of immune pathways. The purpose of this review was to delineate our current knowledge of the host response in periodontitis. The role of innate immunity, the failure of acute inflammation to resolve (thus becoming chronic), the cytokine pathways that regulate the activation of acquired immunity and the cells and products of the immune system are considered. New information relating to regulation of both inflammation and the immune response will be reviewed in the context of susceptibility to, and perhaps control of, periodontitis.

Abstract
Mesenchymal stem cells (MSCs) have potential to differentiate into multiple cell lineages. Recently, it was shown that MSCs also have anti-inflammatory and immunomodulatory functions. In this report, we investigated the regulatory function of MSCs in the development of inflammatory bone destruction in rats with adjuvant-induced arthritis (AA rats). MSCs were isolated from rat bone marrow tissues, expanded in the presence of basic FGF, and intraperitoneally injected into AA rats. MSC administration significantly suppressed inflammatory parameters: swelling score, swelling width, and thickness of hind paw. Radiographic evaluation indicated that MSC significantly suppressed bone destruction. Histological analysis showed that administration of MSCs markedly suppressed osteoclastogenesis in AA rats. To further delineate their effects on osteoclastogenesis, MSCs were added to in vitro bone marrow cultures undergoing osteoclastogenesis. MSCs significantly suppressed osteoclastogenesis in this system. Chemokine receptor expression in MSCs was assessed by RT-PCR, and a chemotactic assay was performed using a transwell culture system. MSCs showed significant chemotaxis to MIP-1α (CCL3) and SDF-1α (CXCL12), chemokines preferentially expressed in the area of inflammatory bone destruction. Furthermore, MSCs expressed IL-10 and osteoprotegerin, cytokines that suppress osteoclastogenesis. These data suggest that recruitment of MSC to the area of bone destruction in AA rats could suppress inflammatory bone destruction and raise the possibility that MSCs may have potential for the treatment of inflammatory bone destruction in arthritis.

Abstract
Periodontal disease is a pathological condition that involves inflammation of the tooth supporting structures. It occurs in response to the presence of bacterial plaque on the tooth structure. The host defense system, including innate and adaptive immunity, is responsible for combating the pathologic bacteria invading the periodontal tissue. Failure to eradicate the invading pathogens will result in a continuous state of inflammation where inflammatory cells such as lymphocytes, PMNs, and macrophages will continue to produce inflammatory mediators in an effort to destroy the invaders. Unfortunately, these inflammatory mediators have a deleterious effect on the host tissue as well as foreign microbes. One of the effects of these mediators on the host is the induction of matrix degradation and bone resorption through activation of proteases and other inflammatory mediators that activate osteoclasts.

Abstract
BACKGROUND AND OBJECTIVE Periodontitis is a chronic inflammatory disease that leads to bone resorption by osteoclasts (OCs). Several factors contribute to the differentiation of OCs from hematopoietic precursors. Cellular chemotactic factors are expressed in periodontitis tissue, but the effects of these chemoattractants on OCs are not well understood. Here we examined the effects of chemoattractants produced in inflamed periodontal tissue on OC chemotaxis. MATERIAL AND METHODS Rat bone-marrow OCs were cultured in OC culture medium for 3 or 6 d. Using EZ-TAXIScan™, the chemotactic response of these OCs to several chemoattractants [monocyte chemotactic protein-1; macrophage inflammatory protein 1α; regulated on activation, normal T-cell expressed and secreted; stromal cell-derived factor-1α; and complement activation product 5a (C5a)] was measured. In addition, we measured the effect of C5a-specific inhibitors on chemotactic responses toward C5a. The recorded chemotactic responses were quantitatively analysed using ImageJ software. RESULTS Chemoattractants associated with periodontal disease significantly increased the chemotactic activity of differentiated rat OCs in a concentration-dependent manner, with C5a inducing the highest chemotactic activity of OCs cultured for 3 or 6 d. The C5a-specific inhibitor significantly inhibited chemotaxis toward C5a in a concentration-dependent manner. CONCLUSION We suggest that C5a plays an important role in pathologic bone resorption in periodontal disease by stimulating the chemotaxis of OCs. Therefore, C5a is a potential target for the treatment of periodontal disease.

Abstract
The chemokine CCL3/MIP-1α is a risk factor in the outcome of multiple myeloma (MM), particularly in the development of osteolytic bone disease. This chemokine, highly overexpressed by MM cells, can signal mainly through 2 receptors, CCR1 and CCR5, only 1 of which (CCR1) is responsive to CCL3 in human and mouse osteoclast precursors. CCR1 activation leads to the formation of osteolytic lesions and facilitates tumor growth. Here we show that formation of mature osteoclasts is blocked by the highly potent and selective CCR1 antagonist CCX721, an analog of the clinical compound CCX354. We also show that doses of CCX721 selected to completely inhibit CCR1 produce a profound decrease in tumor burden and osteolytic damage in the murine 5TGM1 model of MM bone disease. Similar effects were observed when the antagonist was used prophylactically or therapeutically, with comparable efficacy to that of zoledronic acid. 5TGM1 cells were shown to express minimal levels of CCR1 while secreting high levels of CCL3, suggesting that the therapeutic effects of CCX721 result from CCR1 inhibition on non-MM cells, most likely osteoclasts and osteoclast precursors. These results provide a strong rationale for further development of CCR1 antagonists for the treatment of MM and associated osteolytic bone disease.

Abstract
Inflammation is a complex reaction to injurious agents and includes vascular responses, migration, and activation of leukocytes. Inflammation starts with an acute reaction, which evolves into a chronic phase if allowed to persist unresolved. Acute inflammation is a rapid process characterized by fluid exudation and emigration of leukocytes, primarily neutrophils, whereas chronic inflammation extends over a longer time and is associated with lymphocyte and macrophage infiltration, blood vessel proliferation, and fibrosis. Inflammation is terminated when the invader is eliminated, and the secreted mediators are removed; however, many factors modify the course and morphologic appearance as well as the termination pattern and duration of inflammation. Chronic inflammatory illnesses such as diabetes, arthritis, and heart disease are now seen as problems that might have an impact on the periodontium. Reciprocal effects of periodontal diseases are potential factors modifying severity in the progression of systemic inflammatory diseases. Macrophages are key cells for the inflammatory processes as regulators directing inflammation to chronic pathological changes or resolution with no damage or scar tissue formation. As such, macrophages are involved in a remarkably diverse array of homeostatic processes of vital importance to the host. In addition to their critical role in immunity, macrophages are also widely recognized as ubiquitous mediators of cellular turnover and maintenance of extracellular matrix homeostasis. In this review, our objective is to identify macrophage-mediated events central to the inflammatory basis of chronic diseases, with an emphasis on how control of macrophage function can be used to prevent or treat harmful outcomes linked to uncontrolled inflammation.

Abstract
The chemokine receptor CCR1 has been the target of intensive research for nearly two decades. Small-molecule antagonists were first reported in 1998 and, since then, many inhibitors for CCR1 have been brought forth. Yet, with all the money and time spent, to date, no small-molecule antagonists have successfully moved past Phase II clinical trials. With the current advancement of CCR1 antagonists by Bristol-Myers Squibb and Chemocentrix, there has been renewed interest. In this review, we present an overview of CCR1, its activating ligands, methods of signaling, and downstream response. We discuss studies that indicate CCR1 plays an important role in multiple myeloma and the underlying molecular mechanisms. Finally, we present an overview of the clinical and preclinical compounds for CCR1. We address individual structures, discuss their pharmacological précis, and summarize the published evidence to assess their value for use in multiple myeloma.

Abstract
It is commonly accepted that cancer cells interact with host cells to create a microenvironment favoring malignant colonization. The complex bone microenvironment produces an ever changing array of cytokines and growth factors. In this study, we examined levels of MCP-1, IL-6, KC, MIP-2, VEGF, MIG, and eotaxin in femurs of athymic nude mice inoculated via intracardiac injection with MDA-MB-231GFP human metastatic breast cancer cells, MDA-MB-231BRMS1GFP, a metastasis suppressed variant, or PBS. Animals were euthanized (day 3, 11, 19, 27 after injection) to examine femoral cytokine levels at various stages of cancer cell colonization. The epiphysis contained significantly more cytokines than the diaphysis except for MIG which was similar throughout the bone. Variation among femurs was evident within all groups. By day 27, MCP-1, MIG, VEGF and eotaxin levels were significantly greater in femurs of cancer cell-inoculated mice. These pro-osteoclastic and angiogenic cytokines may manipulate the bone microenvironment to enhance cancer cell colonization.

Abstract
Lipopolysaccharide (LPS) has been shown to be a prominent pathogenic factor in inflammatory bone loss. However, knowledge of the mechanisms involved is limited. The role of the SDF-1/CXCR4 (Stromal-derived factor-1 and its unique chemokine receptor) axis in LPS-induced bone loss has not been studied. The aim of this study was to investigate the role of the SDF-1/CXCR4 axis in LPS-stimulated inflammatory bone loss. The results show that LPS does not influence the expression of SDF-1/CXCR4 in osteoblasts, but up-regulates the expression of CXCR4 in pre-osteoclasts via Toll-like receptor 4, which subsequently enhances pre-osteoclast migration. Moreover, LPS promoted RANKL-induced osteoclast differentiation partially through CXCR4 up-regulation. In conclusion, the present study demonstrated, for the first time, that the up-regulated expression of CXCR4 in pre-osteoclasts by LPS stimulation is involved in LPS-induced bone resorption.

Abstract
Chemokines are characterized by the homing activity of leukocytes to targeted inflammation sites. Recent research indicates that chemokines play more divergent roles in various phases of pathogenesis as well as immune reactions. The chemokine receptor, CCR1, and its ligands are thought to be involved in inflammatory bone destruction, but their physiological roles in the bone metabolism in vivo have not yet been elucidated. In the present study, we investigated the roles of CCR1 in bone metabolism using CCR1-deficient mice. Ccr1(-/-) mice have fewer and thinner trabecular bones and low mineral bone density in cancellous bones. The lack of CCR1 affects the differentiation and function of osteoblasts. Runx2, Atf4, Osteopontin, and Osteonectin were significantly up-regulated in Ccr1(-/-) mice despite sustained expression of Osterix and reduced expression of Osteocalcin, suggesting a lower potential for differentiation into mature osteoblasts. In addition, mineralized nodule formation was markedly disrupted in cultured osteoblastic cells isolated from Ccr1(-/-) mice. Osteoclastogenesis induced from cultured Ccr1(-/-) bone marrow cells yielded fewer and smaller osteoclasts due to the abrogated cell-fusion. Ccr1(-/-) osteoclasts exerted no osteolytic activity concomitant with reduced expressions of Rank and its downstream targets, implying that the defective osteoclastogenesis is involved in the bone phenotype in Ccr1(-/-) mice. The co-culture of wild-type osteoclast precursors with Ccr1(-/-) osteoblasts failed to facilitate osteoclastogenesis. This finding is most likely due to a reduction in Rankl expression. These observations suggest that the axis of CCR1 and its ligands are likely to be involved in cross-talk between osteoclasts and osteoblasts by modulating the RANK-RANKL-mediated interaction.

Abstract
Surface molecules of pathogens play an important role in stimulating host immune responses. Elucidation of the signaling pathways activated by critical surface molecules in host cells provides insight into the molecular pathogenesis resulting from bacteria-host interactions. MspTL is the most abundant outer membrane protein of Treponema lecithinolyticum, which is associated with periodontitis, and induces expression of a variety of proinflammatory factors. Although bacteria and bacterial components like LPS and flagellin are known to induce IFN-beta, induction by bacterial surface proteins has not been reported. In the present study, we investigated MspTL-mediated activation of signaling pathways stimulating up-regulation of IFN-beta and IFN-stimulated genes in a human monocytic cell line, THP-1 cells, and primary cultured human gingival fibroblasts. MspTL treatment of the cells induced IFN-beta and the IFN-stimulated genes IFN-gamma-inducible protein-10 (IP-10) and RANTES. A neutralizing anti-IFN-beta Ab significantly reduced the expression of IP-10 and RANTES, as well as STAT-1 activation, which was also induced by MspTL. Experiments using specific small interfering RNA showed that MspTL activated TANK-binding kinase 1 (TBK1), but not inducible IkappaB kinase (IKKi). MspTL also induced dimerization of IFN regulatory factor-3 (IRF-3) and translocation into the nucleus. The lipid rapid-disrupting agents methyl-beta-cyclodextrin, nystatin, and filipin inhibited the MspTL internalization and cellular responses, demonstrating that lipid raft activation was a prerequisite for MspTL cellular signaling. Our results demonstrate that MspTL, the major outer protein of T. lecithinolyticum, induced IFN-beta expression and subsequent up-regulation of IP-10 and RANTES via TBK1/IRF-3/STAT-1 signaling secondary to lipid raft activation.

Abstract
The clinical findings that alendronate blunted the anabolic effect of human parathyroid hormone (PTH) on bone formation suggest that active resorption is involved and enhances the anabolic effect. PTH signals via its receptor on the osteoblast membrane, and osteoclasts are impacted indirectly via the products of osteoblasts. Microarray with RNA from rats injected with human PTH or vehicle showed a strong association between the stimulation of monocyte chemoattractant protein-1 (MCP-1) and the anabolic effects of PTH. PTH rapidly and dramatically stimulated MCP-1 mRNA in the femora of rats receiving daily injections of PTH or in primary osteoblastic and UMR 106-01 cells. The stimulation of MCP-1 mRNA was dose-dependent and a primary response to PTH signaling via the cAMP-dependent protein kinase pathway in vitro. Studies with the mouse monocyte cell line RAW 264.7 and mouse bone marrow proved that osteoblastic MCP-1 can potently recruit osteoclast monocyte precursors and facilitate receptor activator of NF-kappaB ligand-induced osteoclastogenesis and, in particular, enhanced fusion. Our model suggests that PTH-induced osteoblastic expression of MCP-1 is involved in recruitment and differentiation at the stage of multinucleation of osteoclast precursors. This information provides a rationale for increased osteoclast activity in the anabolic effects of PTH in addition to receptor activator of NF-kappaB ligand stimulation to initiate greater bone remodeling.

Abstract
The chemokine CXCL12 (variously termed stromal-derived factor 1 or B cell-stimulating factor) is a highly conserved chemotactic cytokine belonging to the large family of CXC chemokines. CXCL12 has crucial roles in the formation of multiple organ systems during embryogenesis and in the regulation of bone marrow haematopoiesis and immune function in the postnatal organism. Although considered an important factor in normal bone metabolism, recent studies implicate CXCL12 in the pathogenesis of several diseases involving the skeleton, including rheumatoid arthritis and cancers that metastasize to bone. Recent studies have highlighted an emerging role for CXCL12 in the processes of physiological and pathological bone remodelling.

Abstract
The chemokine CCL23 is primarily expressed in cells of the myeloid lineage but little information about its regulation is available. In this study, it is demonstrated that IL-4 and IL-13 induced CCL23 expression in human peripheral blood monocytes. GM-CSF had no effect on its own but synergized with IL-4, but not IL-13. CCL23 promoter reporter gene constructs were sensitive to IL-4 stimulation in the presence of the transcription factor STAT6. A canonical STAT6 binding site in the promoter region of the CCL23 gene was critical for the IL-4-inducible phenotype because reporter plasmids with a defective STAT6 binding site were unable to respond to IL-4 stimulation. In addition, two tandem copies of the STAT6 site conferred cytokine responsiveness to a heterologous minimal promoter. Furthermore, IL-4 inducibility of the CCL23 promoter was dependent on the absence of a negatively acting cis-element downstream of the STAT6 binding site. The negative function of this element was operative also on heterologous IL-4-inducible promoters. CCL23 was also expressed in skin from patients suffering from atopic dermatitis at higher levels than in normal individuals. However, no correlation between CCL23 expression in the serum and IgE levels as a diagnostic marker for atopy was found. Collectively, these data suggest a link between the inducible phenotype of CCL23 expression in monocytes by the prototype Th2 molecule pair IL-4/STAT6 and the increased number of CCL23-expressing cells in skin of atopic dermatitis patients.

Abstract
Expression of CCL23 is induced by external stimuli including PMA in monocytes, but its transcriptional regulation has not been studied to date. Serial deletion analysis of its 5' flanking region revealed that the region -293 to +31 was important for induction by PMA. Cis-acting elements at the -269/-264 (NFAT site), -167/-159 (NF-kappaB site), and -51/-43 (AP-1 site) positions were identified as the critical sites for the CCL23 expression in U937 cells. We demonstrated the binding of the transcription factors to the consensus sites. Specific inhibitors for signal pathways reduced PMA-induced expression of CCL23, confirming involvement of these transcription factors.

Abstract
Development and repair of the vertebrate skeleton requires the precise coordination of bone-forming osteoblasts and bone-resorbing osteoclasts. In diseases such as osteoporosis, bone resorption dominates over bone formation, suggesting a failure to harmonize osteoclast and osteoblast function. Here, we show that mice expressing a constitutively nuclear NFATc1 variant (NFATc1(nuc)) in osteoblasts develop high bone mass. NFATc1(nuc) mice have massive osteoblast overgrowth, enhanced osteoblast proliferation, and coordinated changes in the expression of Wnt signaling components. In contrast, viable NFATc1-deficient mice have defects in skull bone formation in addition to impaired osteoclast development. NFATc1(nuc) mice have increased osteoclastogenesis despite normal levels of RANKL and OPG, indicating that an additional NFAT-regulated mechanism influences osteoclastogenesis in vivo. Calcineurin/NFATc signaling in osteoblasts controls the expression of chemoattractants that attract monocytic osteoclast precursors, thereby coupling bone formation and bone resorption. Our results indicate that NFATc1 regulates bone mass by functioning in both osteoblasts and osteoclasts.

Abstract
Periodontitis is characterized by an accumulation of inflammatory cells in periodontal tissue and subgingival sites. Leukocytes play a major role in the host response to Porphyromonas gingivalis, a major aetiological agent of chronic periodontitis. Secretion of high levels of inflammatory mediators, including cytokines and prostaglandins, by leucocytes is believed to contribute to periodontal tissue destruction. The aim of this study was to investigate the inflammatory response of an ex vivo whole blood model to P. gingivalis stimulation. The production of interleukin-1 beta (IL-1beta), IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-13, tumour necrosis factor alpha (TNF-alpha), interferon gamma (IFN-gamma), IFN-gamma-inducible protein 10 (IP-10), monocyte chemoattractant protein-1 (MCP-1), Regulated on Activation Normal T cell Expressed and Secreted (RANTES) and prostaglandin E2 (PGE2) were quantified by enzyme-linked immunosorbent assays. P. gingivalis induced the secretion of the pro-inflammatory cytokines IL-1beta, TNF-alpha, IL-6 and IFN-gamma, the chemokines IL-8, RANTES and MCP-1 and the inflammatory mediator PGE2 in an ex vivo human whole blood model. The secretion levels were dependent on the strain and the infectious dose used. While the mediator profiles were comparable between six healthy subjects, a high interindividual variability in the levels of secreted mediators was observed. This study supports the view that P. gingivalis, by inducing high levels of inflammatory mediators from a mixed leucocyte population, can contribute to the progression of periodontitis.

Abstract
Rapid progress has been made in recent years in our understanding of the mechanisms regulating the formation, activation, and survival of osteoclasts, which are derived from precursor cells in the myeloid lineage. In contrast, study of the regulation of osteoclast precursors (OCPs) has been relatively slow, in part because it has been hard to accurately identify them. However, following the discovery of cell-surface markers that facilitated purification of OCPs, recent studies have demonstrated that peripheral blood OCP numbers are increased in tumor necrosis factor (TNF)-mediated arthritis, both in animals and humans, and these numbers correlate with serum TNF levels. The increase can be reversed by anti-TNF therapy. Furthermore, the precursor cells that give rise to osteoclasts can also differentiate into other cell types, including dendritic cells. Receptor activator nuclear factor-kappaB ligand (RANKL) stimulates OCPs to produce pro-inflammatory cytokines and chemokines, and RANKL blockade prevents joint inflammation in a murine model of inflammatory arthritis. These findings suggest that OCPs may serve as a source for both osteoclasts and other effector cells and participate actively in the pathogenesis of diseases. Here, we review our current understanding of the regulation of OCP formation and differentiation and provide a model of a vicious cycle in which pro-inflammatory cytokines produced in inflamed joints feedback on the bone marrow to promote the generation and release of OCPs. The OCPs then home to the inflamed joints to differentiate into mature osteoclasts or to produce more inflammatory factors in the presence of RANKL. Disruption of this cycle could provide a new strategy for the development of drugs to treat inflammatory arthritis and other disorders associated with elevated OCP/myeloid progenitors.

Abstract
Human CCL23 (also known as CKbeta8, MPIF-1, or MIP-3) has been recently reported to induce endothelial cell migration and tube formation via CCR1. Matrix metalloproteinases (MMPs) are involved in the degradation of the extracellular matrix and also appear to play critical roles in angiogenesis. In the present study, we have demonstrated that CCL23 enhances the expression of MMP-2 mRNA and protein levels in endothelial cells in a dose-dependent manner, but has no effect on the expression levels of MMP-9, TIMP-1, TIMP-2, and MT1-MMP. CCL23 was shown to dose-dependently activate the expression of the MMP-2/Luc reporter gene, thereby indicating that it stimulates the transcription of the MMP-2 gene. Vascular endothelial cells, when exposed to CCL23, showed a marked ability to invade through a 3D Matrigel. This increase in invasion was also correlated with enhancements in the expression and activity of MMP-2. Neutralization with anti-CCL23 and anti-CCR1 antibodies, as well as the heat-induced inactivation of CCL23, resulted in a blockage of the CCL23-activated invasion, indicating that the invasion of HUVECs was induced by CCL23 specifically. Furthermore, we showed that the CCL23-induced invasion was inhibited by MMP inhibitors such as GM6001 and a specific MMP-2 Inhibitor I. Our results indicate that CCL23 may play a direct role in angiogenesis, via the upregulation of MMP-2 expression.

Abstract
Osteoclasts differentiate from hematopoietic precursors under systemic and local controls. Chemokines and receptors direct leukocyte traffic throughout the body and may help regulate site-specific bone resorption. We investigated bone gene expression in vivo during rapid osteoclast differentiation induced by colony-stimulating factor 1 (CSF-1) in Csf1-null toothless (tl/tl) rats. Long-bone RNA from CSF-1-treated tl/tl rats was analyzed by high-density microarray over a time course. TRAP (tartrate-resistant acid phosphatase)-positive osteoclasts appeared on day 2, peaked on day 4, and decreased slightly on day 6, as marrow space was expanding. TRAP and cathepsin K mRNA paralleled the cell counts. We examined all chemokine and receptor mRNAs on the arrays. CCL9 was strongly induced and peaked on day 2, as did its receptor, CCR1, and regulatory receptors c-Fms (CSF-1 receptor) and RANK (receptor activator of nuclear factor kappaB). Other chemokines and receptors showed little or no significant changes. In situ hybridization and immunohistochemistry revealed CCL9 in small, immature osteoclasts on day 2 and in mature cells at later times. Anti-CCL9 antibody inhibited osteoclast differentiation in culture and significantly suppressed the osteoclast response in CSF-1-treated tl/tl rats. While various chemokines have been implicated in osteoclastogenesis in vitro, this first systematic analysis of chemokines and receptors during osteoclast differentiation in vivo highlights the key role of CCL9 in this process.

Abstract
BACKGROUND Periapical lesions are thought to be the result of a local inflammatory response mediated by inflammatory cell infiltration and production of inflammatory mediators. Although chemokines are strongly implicated in the migration and activation of leukocytes in different inflammatory diseases and experimental models, little is known regarding the expression of chemokines and their receptors in human apical periodontitis. OBJECTIVE AND METHODS The objective of this study was to determine the expression of chemokines and their receptors by real-time polymerase chain reaction in samples obtained from healthy gingiva, periapical granulomas, and inflammatory periradicular cysts. The inflammatory infiltrate was characterized by immunohistochemistry. RESULTS Comparing cysts and granulomas, an increase in CD4+ and CD8+ cells was observed in granulomas, despite the similar numbers of CD45RO-positive cells detected in both lesions. The analysis of mRNA expression revealed increased levels of CCR1, CCR2, CCR3, CCR5, CXCR1, and CXCR3 in both types of lesion compared with controls. Cysts exhibited a higher expression of CCR3, CCR5, CXCR1, and CXCR3 compared to granulomas. A significantly higher expression of RANTES, IP-10, and MCP-1 was detected in cysts compared with controls or granulomas. The expression of interleukin-8, MIP-1alpha, and MIP-1beta was not different in the three experimental groups. CONCLUSIONS The increase in Th1 type (CCR1, CCR5, and CXCR3) and Th2 type (CCR2 and CCR3) receptors in both periapical lesions suggests the concomitant occurrence of Th1 and Th2 responses. Furthermore, the prevalent expression of the receptors CCR3, CCR5, CXCR1, and CXCR3 and of the chemokines RANTES, IP-10, and MCP-1 in cysts may point to a role in the progression of granulomas to cysts.

Abstract
BACKGROUND & AIMS Regulation of gene expression in the follicle-associated epithelium (FAE) over Peyer's patches is largely unknown. CCL20, a chemokine that recruits immature dendritic cells, is one of the few FAE-specific markers described so far. Lymphotoxin beta (LTalpha1beta2) expressed on the membrane of immune cells triggers CCL20 expression in enterocytes. In this study, we measured expression profiles of LTalpha1beta2-treated intestinal epithelial cells and selected CCL20 -coregulated genes to identify new FAE markers. METHODS Genomic profiles of T84 and Caco-2 cell lines treated with either LTalpha1beta2, flagellin, or tumor necrosis factor alpha were measured using the Affymetrix GeneChip U133A. Clustering analysis was used to select CCL20 -coregulated genes, and laser dissection microscopy and real-time polymerase chain reaction on human biopsy specimens was used to assess the expression of the selected markers. RESULTS Applying a 2-way analysis of variance, we identified regulated genes upon the different treatments. A subset of genes involved in inflammation and related to the nuclear factor kappaB pathway was coregulated with CCL20 . Among these genes, the antiapoptotic factor TNFAIP3 was highly expressed in the FAE. CCL23 , which was not coregulated in vitro with CCL20 , was also specifically expressed in the FAE. CONCLUSIONS We have identified 2 novel human FAE specifically expressed genes. Most of the CCL20 -coregulated genes did not show FAE-specific expression, suggesting that other signaling pathways are critical to modulate FAE-specific gene expression.

Abstract
The expression and functions of receptors for the beta-chemokine, regulated upon activation, normal T cell expressed, and secreted (RANTES)/CCL5, were investigated in osteoblasts. Both primary osteoblasts and the MC3T3-E1 osteoblast cell line express the RANTES receptors, CCR1, 3, 4, and 5 (by RT-PCR), which encode functional receptors in osteoblasts as shown by [125I]-RANTES binding followed by Scatchard analysis. Expression of all four RANTES receptor mRNAs in osteoblast is in contrast to the reports of expression of CCR1 being the only RANTES receptor expressed by osteoclasts. Exogenous RANTES elicits chemotaxis of osteoblasts and promotes cell survival via phosphatidylinositol 3-kinase with attendant phosphorylation of Akt. Osteoclastic RANTES, obtained from the conditioned medium of receptor activator of nuclear factor-kappa B ligand-differentiated RAW264.7 cells also induces chemotaxis of MC3T3-E1 cells. Incubating the conditioned medium with an anti-RANTES neutralizing antibody attenuated this effect. RANTES secretion from osteoblast is inhibited by differentiation promoting hormones, e.g. 1,25 (OH)2D3 and dexamethasone, whereas macrophage inflammatory protein-1 alpha (but not macrophage inflammatory protein-1 beta) and elevated calcium induce it. Elevated calcium also stimulated RANTES secretion by osteoclasts. Therefore, RANTES is an osteoblast chemoattractant and a survival-promoting molecule whose regulation in osteoblast is varied. Furthermore, RANTES secreted from osteoclasts induces osteoblast chemotaxis. Therefore, expression of RANTES and its receptors in both osteoblasts and osteoclasts could enable this chemokine to act in autocrine/paracrine modes.

Abstract
UNLABELLED Chemoattractants that recruit OC precursors to locally inflamed sites of resorption are not well known. A chemokine receptor, CCR1, was expressed in OC precursors and elevated in mature OCs, and its ligands promoted OC precursor recruitment, RANKL development, and OC motility. Cytokines induced OB release of such chemokines, which may therefore significantly contribute to inflammatory bone loss. INTRODUCTION Chemokines, primarily of two major (CXC, CC) families, are essential signals for the trafficking and localization of circulating hematopoietic cells into tissues. However, little is known about their potential roles in osteoclast (OC) recruitment, development, or function. Previously, we analyzed CXC receptors in murine OC precursors and found high expression of CXCR4 that mediated their stromal-derived factor-1(SDF-1)-induced chemotaxis and collagen invasion. Here, we investigated if CC receptors and ligands, which are elevated in inflammatory and other osteolytic diseases, also play important roles in the recruitment, formation, or activity of murine bone-resorptive OCs. MATERIALS AND METHODS CC chemokine receptor (CCR) mRNA expression was analyzed during OC formation induced by RANKL in murine RAW 264.7 cells and primary marrow cells. Corresponding CC chemokines were tested for their ability to elicit precursor chemotaxis or OC development, or to influence motility, bone resorption, adhesion, or survival in RANKL-differentiated OCs. Constitutive and inflammatory cytokine-induced release of the chemokines macrophage inflammatory protein-1alpha (MIP-1alpha) and regulated on activation, normal T-cell expressed and secreted (RANTES) was measured by ELISA for OCs, osteoblasts (OBs), and their precursor cells. RESULTS CCR1 was expressed in murine marrow cells, the most prominent CCR in RAW cells, and upregulated by RANKL in marrow or RAW cells. Chemokines that bind CCR1 (MIP-1alpha, RANTES, and monocyte chemoattractant protein-3 [MCP-3]) were produced to varying degrees by murine OCs, OBs, and their precursors, and markedly increased by interleukin (IL)-1alpha and TNFalpha in differentiating OBs. RANTES, and especially MIP-1alpha, increased mature OC motility, but did not alter OC resorption activity, adhesion, or survival. All three chemokines stimulated chemotaxis of marrow or RAW cell precursors, leading to the greater formation of OCs (in number and size) after RANKL development of such chemoattracted marrow cells. All three chemokines also directly and dramatically enhanced OC formation in marrow cultures, through a pathway dependent on the presence of RANKL but without altering RANK expression. CONCLUSIONS Pathological increases in secretion of these chemokines from activated OBs or other cells may potently stimulate the chemotactic recruitment and RANKL formation of bone-resorptive OCs, thereby exacerbating local osteolysis in multiple skeletal diseases.

Abstract
In the rat model of rheumatoid arthritis, a marked formation of osteoclasts is found in the distal tibia and the metatarsal bone. It was therefore postulated that osteoclast progenitors would be increased in the bone marrow cavities of rats with adjuvant-induced arthritis (AA rats). Bone marrow cells obtained from tibia of AA rats were cultured to form cells in the osteoclast lineage to access the number of osteoclast progenitors. Unexpectedly, only a suppressed level of osteoclast progenitors was detected in the diaphyseal bone marrow of tibia in AA rats. Distribution of osteoclast progenitors in the bone marrow cavity was examined, and it was shown that osteoclast progenitors accumulated in the distal tibia. Macrophage inflammatory protein (MIP)-1alpha, an osteoclastogenic CC chemokine, was expressed in ED-1-positive macrophages localizing in the distal tibia with marked bone destruction. Chemotaxis studies showed that MIP-1alpha expressed significant activity towards bone marrow cells. The suppressed level of osteoclastogenesis in bone marrow cells of AA rats was restored to a normal level by the addition of MIP-1alpha. It was suggested that MIP-1alpha is involved in the migration of osteoclast progenitors to the distal tibia as well as in osteoclastogenesis in AA rats. In these rats, in situ hybridization of the distal tibia with a high level of bone destruction showed significant expression of Receptor activator nuclear factor kappaB ligand (RANKL) messenger RNA in aggregates of multinucleated osteoclast-like cells present in the bone marrow cavity, a unique pathological feature for these rats. Migrated osteoclast progenitors are thought to be efficiently differentiated into osteoclasts in response to RANKL expressed by the aggregates of osteoclast-like cells under the influence of the MIP-1alpha. Such positive-feedback regulation of osteoclastogenesis could result in the highest recruitment of active osteoclasts in the area of marked bone destruction.

Abstract
1. Human formyl peptide-receptor-like-1 (FPRL-1) is a promiscuous G protein-coupled receptor (GPCR), and belongs to a chemoattractant receptor family protein. This receptor has been reported to interact with various host-derived peptides and lipids involved in inflammatory responses. We described here, a novel role for FPRL-1 as a high-affinity beta-chemokine receptor for an N-terminally truncated form of the CKbeta8 (CCL23/MPIF-1) splice variant CKbeta8-1 (22-137 aa). 2. RT-PCR analysis of mRNA derived from human tissues and cells revealed a predominant expression of FPRL-1 in inflammatory cells, particularly in neutrophils. 3. Intracellular calcium mobilisation assay, used as screening tool, in recombinant Chinese hamster ovary (CHO-K1) and human embryonic kidney (HEK293s) cells coexpressing FPRL-1 and Galpha(16), demonstrated FPRL-1 is a functional high-affinity receptor for CKbeta8-1 (46-137 aa, sCKbeta8-1), with pEC(50) values of 9.13 and 8.85, respectively. 4. The FPRL-1 activation in CHO-K1 cells is mediated by Galpha(i)/Galpha(o) proteins, as assessed by pertussis toxin sensitivity and inhibition of forskolin-induced cyclic AMP accumulation. 5. Binding experiments were performed with a radio-iodinated synthetic peptide, [(125-)I]-WKYMVm, a known potent FPRL-1 agonist. CHO-K1 cell membranes expressing FPRL-1 bound [(125-)I]-WKYMVm with a K(d) value of 9.34. Many known FPRL-1 agonists were tested and sCKbeta8-1 was the most effective nonsynthetic ligand in displacing the radiolabelled agonist, with a pIC(50) of 7.97. 6. The functional significance of sCKbeta8-1 interaction with FPRL-1 was further demonstrated by the activation of polymorphonuclear leukocytes (PMNs) calcium mobilisation and chemotaxis. These interactions were shown to be via FPRL-1 by specific blockade of PMNs activation in the presence of an FPRL-1 antibody.

Abstract
Figure 5 is a proposed model for MIP-1alpha's effects on myeloma bone disease. MIP-1alpha is produced by myeloma cells and directly stimulates OCL formation. In addition MIP-1alpha enhances adhesive interactions between myeloma cells and marrow stromal cells increasing expression of RANKL and IL-6, which further increase bone destruction and tumor burden. The recent evidence from our group and others lead to the conclusion that MIP-1alpha is an important mediator in the debilitating bone destruction in multiple myeloma. Blocking MIP-1alpha expression may have profound effects on myeloma cell growth, homing, and bone destruction in this in vivo model of myeloma. These data suggest that antagonists that decrease MIP-1alpha activity in vivo or blocking MIP-1alpha signaling by neutralizing its receptor may provide therapeutic alternatives for treating patients with myeloma to decrease both their tumor burden and bone destruction.

Abstract
UNLABELLED Screening a cDNA library enriched for genes expressed in OCLs identified ECF-L. ECF-L enhanced OCL formation without increasing RANKL levels. Anti-ECF-L inhibited RANKL-induced OCL formation. These results support a potent role of ECF-L in osteoclastogenesis. INTRODUCTION To investigate the molecular mechanisms that control osteoclastogenesis, we developed an immortalized osteoclast (OCL) precursor cell line that forms mature OCLs in the absence of stromal cells and used it to form pure populations of OCLs. MATERIALS AND METHODS Polymerase chain reaction (PCR) selective cDNA subtraction was used to identify genes that are highly expressed in mature OCLs compared with OCL precursors employing OCL and OCL precursors derived from this cell line. RESULTS Eosinophil chemotactic factor-L (ECF-L), a previously described chemotactic factor for eosinophils, was one of the genes identified. Conditioned media from 293 cells transfected with mECF-L cDNA, or purified ECF-L Fc protein, increased OCL formation in a dose-dependent manner in mouse bone marrow cultures treated with 10(-10) M 1,25(OH)2D3. OCLs derived from marrow cultures treated with ECF-L conditioned media formed increased pit numbers and resorption area per dentin slice compared with OCLs induced by 1,25(OH)2D3 (p < 0.01). Addition of an antisense S-oligonucleotide to mECF-L inhibited OCL formation in murine bone marrow cultures treated only with 10(-9) M 1,25(OH)2D3 compared with the sense S-oligonucleotide control. Time course studies demonstrated that ECF-L acted at the later stages of OCL formation, and chemotactic assays showed that mECF-L increased migration of OCL precursors. mECF-L mRNA was detectable in mononuclear and multinucleated cells by in situ hybridization. Interestingly, a neutralizing antibody to ECF-L blocked RANKL or 10(-9) M 1,25(OH)2D3-induced OCL formation in mouse bone marrow cultures, although ECF-L did not induce RANKL expression. CONCLUSIONS These data show ECF-L is a previously unknown factor that is a potent mediator of OCL formation, which acts at the later stages of OCL formation and enhances the effects of RANKL.

Abstract
Recent data have implicated macrophage inflammatory protein-1alpha (MIP-1alpha) in multiple myeloma (MM)-associated osteolysis. However, it is unclear whether the chemokine's effects are direct, to enhance osteolysis, or indirect and mediated through a reduction in tumor burden, or both. It is also unclear whether MIP-1alpha requires other factors such as receptor activator of nuclear factor-kappaB ligand (RANKL) for its effects on bone. In murine 5TGM1 (Radl) myeloma-bearing mice, administration of neutralizing anti-MIP-1alpha antibodies reduced tumor load assessed by monoclonal paraprotein titers, prevented splenomegaly, limited development of osteolytic lesions, and concomitantly reduced tumor growth in bone. To determine the effects of MIP-1alpha on bone in vivo, Chinese hamster ovary (CHO) cells secreting human MIP-1alpha (CHO/MIP-1alpha) were inoculated into athymic mice. Mice bearing intramuscular CHO/MIP-1alpha tumors developed lytic lesions at distant skeletal sites, which occurred earlier and were larger than those in mice with CHO/empty vector (EV) tumors. When experimental metastases were induced via intracardiac inoculation, mice bearing CHO/MIP-1alpha tumors developed hypercalcemia and significantly more osteolytic lesions than mice bearing CHO/EV tumors, with intramedullary CHO/MIP-1alpha tumors associated with significantly more tartrate-resistant acid phosphatase-positive (TRAP+) osteoclasts. Injection of recombinant MIP-1alpha over calvariae of normal mice evoked a striking increase in osteoclast formation, an effect dependent on RANK/RANKL signaling because MIP-1alpha had no effect in RANK-/- mice. Together, these results establish that MIP-1alpha is sufficient to induce MM-like destructive lesions in bone in vivo. Because, in the 5TGM1 model, blockade of osteoclastic resorption in other situations does not decrease tumor burden, we conclude that MIP-1alpha exerts a dual effect in myeloma, on osteoclasts, and tumor cells.

Abstract
Although much has been learned recently of the mechanisms by which the differentiation of osteoclasts is induced, less is known of the factors that regulate their migration and localization, and their interactions with other bone cells. In related cell types, chemokines play a major role in these processes. We therefore systematically tested the expression of RNA for chemokines and their receptors by osteoclasts. Because bone is the natural substrate for osteoclasts and may influence osteoclast behavior, we also tested expression on bone slices. Quantitative RT-PCR using real-time analysis with SYBR Green was therefore performed on RNA isolated from bone marrow cells after incubation with macrophage-colony stimulating factor (M-CSF) with/without receptor-activator of NFkappaB ligand (RANKL), on plastic or bone. We found that RANKL induced expression of CCL9/MIP-1gamma to levels comparable to that of tartrate-resistant acid phosphatase (TRAP), a major specialized product of osteoclasts. CCL22/MDC, CXCL13/BLC/BCA-1, and CCL25/TECK were also induced. The dominant chemokine receptor expressed by osteoclasts was CCR1, followed by CCR3 and CX3CR1. Several receptors expressed on macrophages and associated with inflammatory responses, including CCR2 and CCR5, were down-regulated by RANKL. CCL9, which acts through CCR1, stimulated cytoplasmic motility and polarization in osteoclasts, identical to that previously observed in response to CCL3/MIP-1alpha, which also acts through CCR1 and is chemotactic for osteoclasts. These results identify CCL9 and its receptor CCR1 as the major chemokine and receptor species expressed by osteoclasts, and suggest a crucial role for CCL9 in the regulation of bone resorption.
