Abstract
Therapies reconstituting autologous antiviral immunocompetence may represent an important prophylaxis and treatment for immunosuppressed individuals. Following hematopoietic cell transplantation (HCT), patients are susceptible to Herpesviridae including cytomegalovirus (CMV). We show in a murine model of HCT that macrophage colony-stimulating factor (M-CSF) promoted rapid antiviral activity and protection from viremia caused by murine CMV. M-CSF given at transplantation stimulated sequential myeloid and natural killer (NK) cell differentiation culminating in increased NK cell numbers, production of granzyme B and interferon-γ. This depended upon M-CSF-induced myelopoiesis leading to IL15Rα-mediated presentation of IL-15 on monocytes, augmented by type I interferons from plasmacytoid dendritic cells. Demonstrating relevance to human HCT, M-CSF induced myelomonocytic IL15Rα expression and numbers of functional NK cells in G-CSF-mobilized hematopoietic stem and progenitor cells. Together, M-CSF-induced myelopoiesis triggered an integrated differentiation of myeloid and NK cells to protect HCT recipients from CMV. Thus, our results identify a rationale for the therapeutic use of M-CSF to rapidly reconstitute antiviral activity in immunocompromised individuals, which may provide a general paradigm to boost innate antiviral immunocompetence using host-directed therapies.

Abstract
OBJECTIVES Pegylated interferon α-2b (PegIFNα-2b) therapy can help inactive hepatitis B surface antigen (HBsAg) carriers (IHCs) achieve clinical cure. To explore and compare the efficacy, safety, and relevant influential factors of PegIFNα-2b monotherapy and PegIFNα-2b-based immunotherapy for IHCs. METHODS This exploratory, prospective, single-center, randomized controlled trial enrolled 40 IHCs who were randomized into group A (PegIFNα-2b treatment for 68 weeks) and group B (two cycles of PegIFNα-2b treatment with a lead-in period of GM-CSF and vaccine treatment before each cycle). The primary endpoint was 68-week HBsAg loss rate. RESULTS At week 68, the HBsAg loss rates were 45.45% [full analysis set (FAS)] and 46.67% [per-protocol set (PPS)]. There was no statistically significant difference in HBsAg loss rate between groups A and B ( P > 0.05). Univariate analysis revealed that age ≤40 years old, baseline HBsAg <200 IU/ml, and 24-week HBsAg decline ≥2 log 10 IU/ml were significantly associated with HBsAg loss in FAS population ( P < 0.05). Multivariate analysis showed that only 24-week HBsAg decline ≥2 log 10 IU/ml was the independent influencing factor in both FAS and PPS populations ( P < 0.05). The adverse events were common and mild, and the therapies were well-tolerated. CONCLUSION Treatment of IHCs with PegIFNα-2b-based therapy could result in a high HBsAg loss rate. The HBsAg loss rate of combined immunotherapy was similar to that of PegIFNα-2b monotherapy, and the safety was good. CLINICALTRIALSGOV ID NCT05451420.

Abstract
Macrophage colony-stimulating factor (CSF1) is the primary growth factor required for the control of monocyte and macrophage differentiation, survival, proliferation and renewal. Although the cDNAs encoding multiple isoforms of human CSF1 were cloned in the 1980s, and recombinant proteins were available for testing in humans, CSF1 has not yet found substantial clinical application. Here we present an overview of CSF1 biology, including evolution, regulation and functions of cell surface and secreted isoforms. CSF1 is widely-expressed, primarily by cells of mesenchymal lineages, in all mouse tissues. Cell-specific deletion of a floxed Csf1 allele in mice indicates that local CSF1 production contributes to the maintenance of tissue-specific macrophage populations but is not saturating. CSF1 in the circulation is controlled primarily by receptor-mediated clearance by macrophages in liver and spleen. Administration of recombinant CSF1 to humans or animals leads to monocytosis and expansion of tissue macrophage populations and growth of the liver and spleen. In a wide variety of tissue injury models, CSF1 administration promotes monocyte infiltration, clearance of damaged cells and repair. We suggest that CSF1 has therapeutic potential in regenerative medicine.

Abstract
Osteoporosis is a systemic bone disease with bone fragility and increased fracture risk. The non-coding RNAs (ncRNAs) have appeared as important regulators of cellular signaling and pertinent human diseases. Studies have demonstrated that circular RNAs (circRNAs) and long non-coding RNAs (lncRNAs) are involved in the progression of osteoporosis through a variety of pathways, and are considered as targets for the prophylaxis and treatment of osteoporosis. Based on an in-depth understanding of their roles and mechanisms in osteoporosis, we summarize the functions and molecular mechanisms of circRNAs and lncRNAs involved in the progression of osteoporosis and provide some new insights for the prognosis, diagnosis and treatment of osteoporosis.

Association of plasma macrophage colony-stimulating factor with cardiovascular morbidity and all-cause mortality in chronic hemodialysis patients. BMC Nephrol 2019; 20:321. [PMID: 31419967 PMCID: PMC6697977 DOI: 10.1186/s12882-019-1510-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2019] [Accepted: 07/31/2019] [Indexed: 11/23/2022] Open
Abstract
Background Cardiovascular disease (CVD) events are the main cause of death in long-term hemodialysis (HD) patients. Macrophage colony- stimulating factor (M-CSF) is actively involved in the formation of atherosclerosis and causes plaque instability, thrombosis and the development of acute coronary syndromes. However, little information is available on the role of M-CSF in HD patients. We aimed to investigate the association between plasma M-CSF levels and CVD events as well as all-cause mortality in patients undergoing long-term HD. Methods Fifty two HD patients and 8 healthy controls were recruited in this study. HD patients were followed up from September 2014 to May 2017. The primary end point was CVD event, the secondary outcome was death from any cause. Patients were divided into two groups with low and high M-CSF levels based on the optimal cut-off value determined by the ROC curve. Cox regression analyses were used to assess the predictive value of plasma M-CSF for CVD events and all-cause mortality in HD patients. We tested the levels of plasma M-CSF and other inflammatory cytokines in surviving HD patients using ELISA or CBA kit. Results The average plasma level of M-CSF in 52 patients was approximately twice that of healthy controls (992.4 vs. 427.2 pg/mL; p < 0.05). During 32 months of follow-up, 26 patients (50.0%) had at least one CVD event and 8 patients (15.4%) died. The mean plasma M-CSF concentration increased in survivors after follow-up compared to that detected at baseline (1277.8 ± 693.3 vs. 997.2 ± 417.4 pg/mL; p < 0.05). Multivariate Cox regression analysis showed that plasma M-CSF is an independent risk factor for CVD events in HD patients (p < 0.05). In the Cox regression model after adjusting for gender and age, high M-CSF levels were related to an increased risk of all-cause death (p < 0.05). We also found that M-CSF levels were positively correlated with IL-6 and IL-18 levels (both p < 0.05), which are the major pathogentic cytokines that contribute to HD-related CVD events. Conclusion M-CSF is a prognostic factor for CVD events and all-cause mortality in HD patients.

Abstract
Osteoclasts are multinucleated cells derived from mononuclear phagocyte precursors (monocytes, macrophages); in the canonical pathway of osteoclastogenesis, these cells fuse and differentiate to form specialised bone-resorbing osteoclasts in the presence of receptor activator for nuclear factor kappa B ligand (RANKL). Non-canonical pathways of osteoclastogenesis have been described in which several cytokines and growth factors are able to substitute for RANKL. These humoral factors can generally be divided into those which, like RANKL, are tumour necrosis family (TNF) superfamily members and those which are not; the former include TNFα lymphotoxin exhibiting inducible expression and competing with herpes simplex virus glycoprotein D for herpesvirus entry mediator, a receptor expressed by T lymphocytes (LIGHT), a proliferation inducing ligand (APRIL) and B cell activating factor (BAFF); the latter include transforming growth factor beta (TGF-β), interleukin-6 (IL-6), IL-8, IL-11, nerve growth factor (NGF), insulin-like growth factor-I (IGF-I) and IGF-II. This review summarises the evidence for these RANKL substitutes in inducing osteoclast differentiation from tissue-derived and circulating mononuclear phagocytes. It also assesses the role these factors are likely to play in promoting the pathological bone resorption seen in many inflammatory and neoplastic lesions of bone and joint including rheumatoid arthritis, aseptic implant loosening and primary and secondary tumours of bone.

Abstract
BACKGROUND Scavenger receptors (SRs) play a pivotal role in atherogenesis. The mechanism of atherosclerosis, which is specific to hemodialysis (HD) patients, was studied on the basis of SR gene expressions. METHODS The gene expressions of SR type A (SR-A) and CD36 were studied in peripheral monocytes by real-time reverse transcription polymerase chain reaction. Data were compared between HD (n = 30) and age-matched control subjects (n = 10). Serum levels of macrophage colony-stimulating factor (M-CSF) were measured with enzyme-linked immunosorbent assay to test its role in SR expression. The statistical differences and associations between two continuous variables were assessed using the Mann-Whitney U test and Pearson's correlation coefficient, respectively. RESULTS The relative quantities of SR mRNAs were significantly greater in HD patients than in controls [median (interquartile range): SR-A, 1.67 (0.96-2.76) vs. 0.90 (0.60-1.04), p = 0.0060; CD36, 1.09 (0.88-1.74) vs. 0.74 (0.64-0.99), p = 0.0255]. The serum concentration of M-CSF was significantly higher in HD patients than in controls [1, 121 (999-1,342) vs. 176 (155-202) pg/ml, p < 0.0001]. In addition, the relative quantity of M-CSF mRNA was significantly greater in HD patients than in controls [0.79 (0.42-1.53) vs. 0.42 (0.28-0.66), p = 0.0392]. The serum M-CSF levels were positively correlated with both the relative quantity of SR-A mRNA (r2 = 0.1681, p = 0.0086) and that of CD36 mRNA (r2 = 0.1202, p = 0.0284) in all subjects (n = 40). CONCLUSION HD patients are predisposed to atherosclerosis as a consequence of their enhanced monocyte SR expressions. SRs and M-CSF are potential therapeutic targets for atherosclerosis in this high-risk population.

Abstract
The colony-stimulating factor-1 (CSF-1) is the principal regulator of the survival, proliferation, differentiation, and function of macrophages and their precursors, and has been shown to play a role in the etiology of inflammation. We recently identified a novel mechanism for the control of CSF-1 activity in teleost fish, through the production of an inhibitory soluble form of the CSF-1 receptor (sCSF-1R). Primary goldfish kidney macrophages selectively expressed sCSF-1R during the senescence phase, which corresponds to a defined stage of in vitro culture development where inhibition of macrophage proliferation and apoptotic cell death are prominent. In contrast, primary macrophage cultures undergoing active proliferation displayed low levels of sCSF-1R expression. Addition of purified recombinant sCSF-1R to developing primary macrophage cultures leads to a dose-dependent decrease in macrophage proliferation and inhibits macrophage antimicrobial functions including chemotaxis, phagocytosis, and production of reactive oxygen intermediates. Using a goldfish in vivo model of self-resolving peritonitis, we found that sCSF-1R plays a role in the inhibition of inflammation, following an initial acute phase of antimicrobial responses within an inflammatory site. Soluble CSF-1R inhibits pro-inflammatory cytokine production, inhibits leukocyte recruitment to the inflammatory site and decreases ROS production in a dose-dependent manner. This sCSF-1R-dependent regulation of inflammation appears to be an elegant mechanism for the control of macrophage numbers at inflammatory sites of lower vertebrates. Overall, our results provide new insights into the evolutionary origins of the CSF-1 immune regulatory axis.

Abstract
Giant cell tumors deriving from synovium are classified into a localized (GCT of tendon sheath; GCT-TS) and diffuse form (diffuse-type GCT, Dt-GCT). We propose a multidisciplinary management based upon a systematic review and authors' opinion. Open excision for GCT-TS and open synovectomy (plus excision) for Dt-GCT is advised to reduce the relatively high recurrence risk. External beam radiotherapy should be considered in severe cases, as Dt-GCT commonly extends extra-articular.

Abstract
Aneurysmal bone cyst (ABC) is a benign osteolytic bone lesion in which there are blood-filled spaces separated by fibrous septa containing giant cells. The nature of the giant cells in this lesion and the mechanism of bone destruction in ABC is not certain. In this study, we have analysed several characteristics of mononuclear and multinucleated cells in the ABC and examined the cellular and molecular mechanisms of ABC osteolysis. The antigenic and functional phenotype of giant cells in ABC was determined by histochemistry/immunohistochemistry using antibodies to macrophage and osteoclast markers. Giant cells and CD14+ and CD14- mononuclear cells were isolated from ABC specimens and cultured on dentine slices and coverslips with receptor activator of nuclear factor κB ligand (RANKL)+/- macrophage-colony stimulating factor (M-CSF) and functional and cytochemical evidence of osteoclast differentiation sought. Giant cells in ABC expressed an osteoclast-like phenotype (CD51+, CD14-, cathepsin K+, TRAP+) and were capable of lacunar resorption, which was inhibited by zoledronate, calcitonin and osteoprotegerin (OPG). When cultured with RANKL±M-CSF, CD14+, but not CD14-, mononuclear cells differentiated into TRAP+ multinucleated cells that were capable of lacunar resorption. M-CSF was not necessary for osteoclast formation from CD14+ cell cultures. CD14- cells variably expressed RANKL, OPG and M-CSF but supported osteoclast differentiation. Our findings show that the giant cells in ABC express an osteoclast-like phenotype and are formed from CD14+ macrophage precursors. CD14- mononuclear stromal cells express osteoclastogenic factors and most likely interact with CD14+ cells to form osteoclast-like giant cells by a RANKL-dependent mechanism.

Secretion of IL-6 and IL-8 from lysophosphatidic acid-stimulated oral squamous cell carcinoma promotes osteoclastogenesis and bone resorption. Oral Oncol 2011; 48:40-8.

Abstract
Lysophosphatidic acid (LPA) is a bioactive lipid with a growth factor-like activity on a large range of cell types. Several pieces of evidence raise the possibility that LPA may play an important role in bone metastasis. Bone is a frequent metastatic site for oral cancer. However, the role of LPA in the progression of oral cancer metastasis to the bone is poorly understood. Here, we provide evidence for the role of LPA in the progression of oral cancer bone metastases and its regulatory mechanism. LPA induced the secretion of IL-6 and IL-8 in oral squamous cell carcinoma (OSCC). LPA-stimulated secretion of IL-6 and IL-8 is partly dependent on the LPA and EGF receptor (EGFR) pathways. ERK1/2 and Akt-mediated NF-κB and AP-1 were responsible for the LPA-induced IL-6 and IL-8 secretion. Moreover, conditioned medium (CM) derived from the LPA-stimulated OSCC supported osteoclast formation in bone marrow-derived macrophages (BMMs). Neutralization against both human IL-6 and IL-8 suppressed osteoclast formation induced by CM derived from the LPA-stimulated OSCC. Direct treatment with recombinant IL-6 (rIL-6) and/or soluble IL-6 receptor (sIL-6R), or IL-8 (rIL-8) reproduced the effect of the CM derived from the LPA-stimulated OSCC on osteoclast formation. In addition, CM derived from the LPA-stimulated OSCC induced receptor activator of nuclear factor (NF)-κB ligand (RANKL) expression in human osteoblasts and direct treatment with rIL-6 and/or sIL-6R or rIL-8 mimicked the effect of the CM derived from the LPA-stimulated OSCC for RANKL expression. Taken together, LPA may be a potent inducer of osteolytic factor IL-6 and IL-8 in OSCC. LPA-induced IL-6 and IL-8 exerted propound effects on RANKL expression in osteoblast and thereby promoted osteoclast formation from osteoclast precursors.

Abstract
Over the past decade, modern genetic tools have permitted scientists to study the function of myeloid lineage cells, including macrophages, as never before. Macrophages were first detected more than a century ago as cells that ingested bacteria and other microbes, but it is now known that their functional roles are far more numerous. In this review, we focus on the prevailing functions of macrophages beyond their role in innate immunity. We highlight examples of macrophages acting as regulators of development, tissue homoeostasis, remodeling (the reorganization or renovation of existing tissues) and repair. We also detail how modern genetic tools have facilitated new insights into these mysterious cells.

Abstract
INTRODUCTION We investigated receptor activator of nuclear factor-kappaB ligand (RANKL) expression by B lymphocytes during early and late aspects of the immune response to Aggregatibacter actinomycetemcomitans, a gram-negative, anaerobic bacterium associated with aggressive periodontal disease. METHODS Expression of messenger RNA transcripts (tumor necrosis factor-alpha, Toll-like receptors 4 and 9, interleukins 4 and 10, and RANKL) involved in early (1-day) and late (10-day) responses in cultured rat splenocytes was examined by reverse transcription-polymerase chain reaction (RT-PCR). The immune cell distribution (T, B, and natural killer cells and macrophages) in cultured rat splenocytes and RANKL expression in B cells were determined by flow cytometric analyses. B-cell capacity for induction of osteoclast differentiation was evaluated by coculture with RAW 264.7 cells followed by a tartrate-resistant acid phosphatase (TRAP) activity assay. RESULTS The expression levels of interleukins 4 and 10 in cultured cells were not changed in the presence of A. actinomycetemcomitans until cultured for 3 days, and peaked after 7 days. After culture for 10 days, the percentages of B and T cells, the overall RANKL messenger RNA transcripts, and the percentage of RANKL-expressing immunoglobulin G-positive cells were significantly increased in the presence of A. actinomycetemcomitans. These increases were considerably greater in cells isolated from A. actinomycetemcomitans-immunized animals than from non-immunized animals. RAW 264.7 cells demonstrated significantly increased TRAP activity when cocultured with B cells from A. actinomycetemcomitans-immunized animals. The addition of human osteoprotegerin-Fc to the culture significantly diminished such increases. CONCLUSION This study suggests that B-lymphocyte involvement in the immune response to A. actinomycetemcomitans through upregulation of RANKL expression potentially contribute to bone resorption in periodontal disease.

Abstract
Specialized phagocytes are found in the most primitive multicellular organisms. Their roles in homeostasis and in distinguishing self from non-self have evolved with the complexity of organisms and their immune systems. Equally important, but often overlooked, are the roles of macrophages in tissue development. As discussed in this Review, these include functions in branching morphogenesis, neuronal patterning, angiogenesis, bone morphogenesis and the generation of adipose tissue. In each case, macrophage depletion impairs the formation of the tissue and compromises its function. I argue that in several diseases, the unrestrained acquisition of these developmental macrophage functions exacerbates pathology. For example, macrophages enhance tumour progression and metastasis by affecting tumour-cell migration and invasion, as well as angiogenesis.

Abstract
The innate immune responses of early vertebrates, such as bony fishes, play a central role in host defence against infectious diseases and one of the most important effector cells of innate immunity are macrophages. In order for macrophages to be effective in host defence they must be present at all times in the tissues of their host and importantly, the host must be capable of rapidly increasing macrophage numbers during times of need. Hematopoiesis is a process of formation and development of mature blood cells, including macrophages. Hematopoiesis is controlled by soluble factors known as cytokines, that influence changes in transcription factors within the target cells, resulting in cell fate changes and the final development of specific effector cells. The processes involved in macrophage development have been largely derived from mammalian model organisms. However, recent advancements have been made in the understanding of macrophage development in bony fish, a group of organisms that rely heavily on their innate immune defences. Our understanding of the growth factors involved in teleost macrophage development, as well as the receptors and regulatory mechanisms in place to control them has increased substantially. Furthermore, model organisms such as the zebrafish have emerged as important instruments in furthering our understanding of the transcriptional control of cell development in fish as well as in mammals. This review highlights the recent advancements in our understanding of teleost macrophage development. We focused on the growth factors identified to be important in the regulation of macrophage development from a progenitor cell into a functional macrophage and discuss the important transcription factors that have been identified to function in teleost hematopoiesis. We also describe the findings of in vivo studies that have reinforced observations made in vitro and have greatly improved the relevance and importance of using teleost fish as model organisms for studying developmental processes.

Abstract
AIMS/HYPOTHESIS Our aims were to compare osteoclastic activity between patients with acute Charcot's osteoarthropathy and diabetic and healthy controls, and to determine the effect of the receptor activator of nuclear factor-kappaB ligand (RANKL) and its decoy receptor osteoprotegerin (OPG). METHODS Peripheral blood monocytes isolated from nine diabetic Charcot patients, eight diabetic control and eight healthy control participants were cultured in the presence of macrophage-colony stimulating factor (M-CSF) alone, M-CSF and RANKL, and also M-CSF and RANKL with excess concentrations of OPG. Osteoclast formation was assessed by expression of tartrate-resistant acid phosphatase on glass coverslips and resorption on dentine slices. RESULTS In cultures with M-CSF, there was a significant increase in osteoclast formation in Charcot patients compared with healthy and diabetic control participants (p=0.008). A significant increase in bone resorption was also seen in the former, compared with healthy and diabetic control participants (p<0.0001). The addition of RANKL to the cultures with M-CSF led to marked increase in osteoclastic resorption in Charcot (from 0.264+/-0.06% to 41.6+/-8.1%, p<0.0001) and diabetic control (0.000+/-0.00% to 14.2+/-16.5%, p<0.0001) patients, and also in healthy control participants (0.004+/-0.01% to 10.5+/-1.9%, p<0.0001). Although the addition of OPG to cultures with M-CSF and RANKL led to a marked reduction of resorption in Charcot patients (41.6+/-8.1% to 5.9+/-2.4%, p=0.001), this suppression was not as complete as in diabetic control patients (14.2+/-16.5% to 0.45+/-0.31%, p=0.001) and in healthy control participants (from 10.5+/-1.9% to 0.00+/-0.00%, p<0.0001). CONCLUSIONS/INTERPRETATION These results indicate that RANKL-mediated osteoclastic resorption occurs in acute Charcot's osteoarthropathy. However, the incomplete inhibition of RANKL after addition of OPG also suggests the existence of a RANKL-independent pathway.

Abstract
Colony-stimulating factor-1 (CSF-1) regulates mononuclear cell proliferation, differentiation, and survival. The functions of CSF-1 are well documented in mammals; however, little is known about CSF-1 biology in lower vertebrates. This is the first report on the identification and functional characterization of a fish CSF-1 molecule expressed highly in the spleen and in phorbol 12-myristate 13-acetate-stimulated monocytes. Goldfish CSF-1 is a 199-amino acid protein that possesses the required cysteine residues to form important intra-chain and inter-chain disulfide bonds that allow CSF-1 to form a functional homodimer and to interact with its high affinity receptor, CSF-1R. Recombinant goldfish CSF-1 formed a homodimer and bound to the soluble goldfish CSF-1R. The addition of the recombinant CSF-1 to sorted goldfish progenitor cells, monocytes, and macrophages induced the differentiation of monocytes into macrophages and the proliferation of monocyte-like cells. The proliferation of these cells was abrogated by addition of an anti-CSF-1R antibody as well as the soluble CSF-1R. The ability of the soluble CSF-1R to inhibit CSF-1-induced proliferation represents a novel mechanism for the regulation of CSF-1 function.

Abstract
The monocyte/macrophage lineage might affect the healing process after myocardial infarction (MI). Because macrophage colony-stimulating factor (M-CSF) stimulates differentiation and proliferation of this lineage, we examined the effect of M-CSF treatment on infarct size and left ventricular (LV) remodeling after MI. MI was induced in C57BL/6J mice by ligation of the left coronary artery. Either recombinant human M-CSF or saline was administered for 5 consecutive days after MI induction. M-CSF treatment significantly reduced the infarct size (P < 0.05) and scar formation (P < 0.05) and improved the LV dysfunction (percent fractional shortening, P < 0.001) after the MI. Immunohistochemistry revealed that M-CSF increased macrophage infiltration (F4/80) and neovascularization (CD31) of the infarct myocardium but did not increase myofibroblast accumulation (alpha-smooth muscle actin). M-CSF mobilized CXCR4(+) cells into peripheral circulation, and the mobilized CXCR4(+) cells were then recruited into the infarct area in which SDF-1 showed marked expression. The CXCR4 antagonist AMD3100 deteriorated the infarction and LV function after the MI in the M-CSF-treated mice. In conclusion, M-CSF reduced infarct area and improved LV remodeling after MI through the recruitment of CXCR4(+) cells into the infarct myocardium by the SDF-1-CXCR4 axis activation; this suggests that the SDF-1-CXCR4 axis is as a potential target for the treatment of MI.

Abstract
Src-like adaptor protein 2 (SLAP-2) is a hematopoietic adaptor protein previously implicated as a negative regulator of T-cell antigen receptor (TCR)-mediated signaling. SLAP-2 contains an SH3 and an SH2 domain, followed by a unique carboxyl-terminal tail, which is important for c-Cbl binding. Here we describe a novel role for SLAP-2 in regulation of the colony-stimulating factor 1 receptor (CSF-1R), a receptor tyrosine kinase important for growth and differentiation of myeloid cells. SLAP-2 co-immunoprecipitates with c-Cbl and CSF-1R in primary bone marrow-derived macrophages. Using murine myeloid cells expressing CSF-1R (FD-Fms cells), we show that SLAP-2 is tyrosine-phosphorylated upon stimulation with CSF-1 and associates constitutively with both c-Cbl and CSF-1R. In addition, we show that expression of a dominant negative form of SLAP-2 impairs c-Cbl association with the CSF-1R and receptor ubiquitination. Impaired c-Cbl recruitment also correlated with changes in the kinetics of CSF-1R down-regulation and trafficking. CSF-1-mediated differentiation of FD-Fms cells and activation of downstream signaling events was also enhanced in cells stably expressing dominant negative SLAP-2. Together, these results demonstrate that SLAP-2 plays a role in c-Cbl-dependent down-regulation of CSF-1R signaling.

Abstract
OBJECTIVE Since the macrophage colony-stimulating factor (M-CSF) has been shown to stimulate differentiation and proliferation of monocyte/macrophage lineage and to be involved in the process of neointimal formation after vascular injury, we tested the effects of M-CSF on the recruitment of bone marrow-derived progenitor cells in neointimal formation after vascular injury in mice. METHODS AND RESULTS Wire-mediated vascular injury was produced in the femoral artery of C57BL/6 mice. Recombinant human M-CSF [500 microg/(kg x day)] or saline (control) was administered for 10 consecutive days, starting 4 days before the injury. Treatment with M-CSF accelerated neointimal formation in the early phase after injury, and this neointimal lesion mainly consisted of bone marrow-derived cells. M-CSF treatment had no effect on the mobilization of endothelial progenitor cells (EPCs: CD34+/Flk-1+) and reendothelialization after injury. The stromal cell-derived factor-1 (SDF-1) was markedly expressed in the neointima and media after injury, whereas CXCR4+ cells were observed in the neointima. Further, a novel CXCR4 antagonist, AMD3100, significantly attenuated the M-CSF-induced neointimal formation. CONCLUSIONS These findings suggest that M-CSF accelerated neointimal formation after vascular injury via the SDF-1-CXCR4 system, and the inhibition of this system has therapeutic potential for the treatment of cardiovascular diseases.

Abstract
OBJECTIVES Macrophages (Mphis) have various functions and play a critical role in host defense and the maintenance of homeostasis. Mphis exist in every tissue in the body, but Mphis from different tissues exhibit a wide range of phenotypes with regard to their morphology, cell surface antigen expression and function, and are called by different names. However, the precise mechanism of the generation of macrophage heterogeneity is not known. In the present study, the authors examined the functional heterogeneity of Mphis generated from human monocytes under the influence of granulocyte-macrophage colony-stimulating factor (GM-CSF) and macrophage-CSF (M-CSF). METHODOLOGY CD14 positive human monocytes (Mos) were incubated with M-CSF and GM-CSF for 6-7 days to stimulate the generation of M-CSF-induced monocyte-derived Mphis (M-Mphis) and GM-CSF-induced monocyte-derived Mphis (GM-Mphis), respectively. The expression of cell surface antigens and several functions such as antigen presenting cell activity, susceptibility to oxidant stress, and the susceptibility to HIV-1 and mycobacterium tuberculosis infection were examined. RESULTS GM-Mphis and M-Mphis are distinct in their morphology, cell surface antigen expression, and functions examined. The phenotype of GM-Mphis closely resembles that of human Alveolar-Mphis (A-Mphis), indicating that CSF-induced human monocyte-derived Mphis are useful to clarify the molecular mechanism of heterogeneity of human Mphis, and GM-Mphis will become a model of human A-Mphis.

Abstract
BACKGROUND AND OBJECTIVES Host immune responses to periodontal pathogens have been considered to contribute to the alveolar bone destruction in periodontitis. However, the role of B lymphocytes in the pathogenesis of periodontal bone loss is not clear. METHODS We examined the effect of adoptive transfer of antigen-specific B cells from rat spleens on experimental periodontal bone resorption. Donor rats were immunized intraperitoneally (i.p.) with formalin-killed Actinobacillus actinomycetemcomitans. Antigen-specific B cells were prepared from splenocytes by first binding CD43(+) cells to Petri dishes coated with anti-CD43 antibody to remove T cells, and non-binding cells were passed through a nylon wool column to deplete accessory cells. The retained cells were then collected and bound to A. actinomycetemcomitans-coated Petri dishes for enrichment of A. actinomycetemcomitans-binding B cells (AAB). A. actinomycetemcomitans non-binding B cells (ANB) and B cells from non-immunized donor rats (NIB) were also collected from these procedures. Each type of B cell was injected into a group of recipient rats that were then orally infected with live A. actinomycetemcomitans. RESULTS At termination, the antibody levels to A. actinomycetemcomitans in serum and gingival wash fluids were significantly higher in the recipients transferred with AAB when compared to the recipients transferred with ANB or NIB. A markedly elevated number of antibody-forming cells were observed in the spleens of the recipients transferred with AAB, and these recipient rats also exhibited significantly increased bone resorption when compared to the other groups. CONCLUSIONS It is suggested that B cells can contribute to periodontal bone resorption and that antigen-triggering of B cells is required for the bone resorption.

Abstract
Over 100 years after the first description of macrophages by Metchnikoff, there are still questions as to the mechanisms leading to the heterogeneity of their lineage. Current views are based on the mononuclear phagocyte system (MPS) theory, where all mammalian macrophages are derived from circulating blood monocytes and ultimately from hematopoietic stem cells in the bone marrow. Our studies on the regulation of fish macrophage development, suggested that teleosts have alternate pathways of monopoiesis, which undoubtedly contribute to macrophage heterogeneity in the goldfish. Macrophage heterogeneity has been attributed to a network of positive and negative regulators of macrophage development, including soluble mediators known as colony-stimulating factors of which two (M-CSF and GM-CSF) promote formation and growth of mature macrophages. In contrast to our knowledge of CSFs and their receptors in mammals, there is no published information about fish macrophage CSFs. Since fish macrophages generate their own growth factors, it is reasonable to assume that pathways of fish macrophage development and hematopoiesis may be distinct from those of mammalian macrophages. More importantly, the presence of fish progenitor/stem cells and developing macrophages in long-term cultures, allowed us to address pathways of macrophage differentiation, which could not be addressed in mammalian macrophage culture systems. Characterization of primary kidney macrophage (PKM) cultures from goldfish hematopoietic tissues (kidney) indicated that three distinct subpopulations developed in response to endogenous macrophage growth factors. These macrophage subpopulations expressed several differentiation markers, including the hematopoietic stem cell antigen AC133, c-kit, granulin, CD63, macrosialin, c/EBPbeta, legumain, and the colony-stimulating factor receptor-1 (CSF-1R). In the goldfish, there appeared to be a stringent control between those early progenitors that self-renewed, and those that were recruited into the maturation pathways. We report that upon commitment, goldfish macrophages developed through two distinct differentiation pathways: one consistent with the "classical" pathway (MPS) of macrophage development (progenitors-->monocytes-->mature macrophages), and an "alternate" pathway (AP-macrophages) where mature macrophages appeared to rapidly develop from early progenitors in the absence of an intermediate monocyte stage. AP-macrophages represent a unique subset of spontaneously growing cells. Their self-renewal was promoted by endogenous macrophage growth factors (MGF), and effectively controlled by a novel soluble form of the CSF-1R (sCSF-1R). The discovery of sCSF-1R in the goldfish highlights the inherent complexity in the hematopoietic regulatory machinery of teleosts.

Abstract
Colony-stimulating factor-1 (CSF-1, also known as macrophage-CSF) is the primary regulator of the survival, proliferation, differentiation and function of mononuclear phagocytes. Studies that involve CSF-1-deficient mice demonstrate that there is a variable requirement for CSF-1 in the development of individual mononuclear phagocyte populations. However, these cells uniformly express the CSF-1 receptor, and their morphology, phagocytosis and responsiveness to infectious and non-infectious stimuli is regulated by CSF-1. CSF-1 plays important roles in innate immunity, cancer and inflammatory diseases, including systemic lupus erythematosus, arthritis, atherosclerosis and obesity. In several conditions, activation of macrophages involves a CSF-1 autocrine loop. In addition, secreted and cell-surface isoforms of CSF-1 can have differential effects in inflammation and immunity.

Abstract
Interferon (IFN)-gamma exerts multiple functions including antiviral, anti-proliferative and immunomodulatory activities, which are mediated through the JAK-STAT pathway. We observed that IFN-gamma significantly increases the production of colony stimulating factor-1 (CSF-1) by a human lung carcinoma cell line, A549. To gain insight into this mechanism, we determined the unknown nucleotide sequences of 5'-flanking region of human CSF-1 gene. About 60 bases upstream of the transcription start site of the CSF-1 gene contains a possible gamma interferon activated site (GAS), TTCCCATAA. The promoter assay and the electrophoretic mobility gel shift assay revealed that IFN-gamma stimulates transcription of the CSF-1 gene through this sequence, which binds STAT1.

Abstract
Because hearing disturbance due to auditory nerve dysfunction imposes a formidable burden on human beings, intense efforts have been expended in experimental and clinical studies to discover ways to restore normal hearing. However, the great majority of these investigations have focused on the peripheral process side of bipolar auditory neurons, and very few trials have focused on ways to halt degenerative processes in auditory neurons from the central process side (in the cerebellopontine angle). In the present study, we investigated whether administration of macrophage colony-stimulating factor (M-CSF) could protect auditory neurons in a rat model of nerve injury. The electrophysiological and morphological results of our study indicated that M-CSF could ameliorate both anterograde (Wallerian) and retrograde degeneration in both the CNS and PNS portions of the auditory nerve. We attribute the success of M-CSF therapy to the reported functional dichotomy (having the potential to cause both neuroprotective and neurotoxic effects) of microglia and macrophages. Whether the activities of microglia/macrophages are neuroprotective or neurotoxic may depend upon the nature of the stimulus that activates the cells. In the present study, the neuroprotective effects of M-CSF that were observed could have been due to M-CSF we administered and to M-CSF released from endothelial cells, resident cells of the CNS parenchyma, or infiltrating macrophages. Another possibility is that M-CSF ameliorated apoptotic auditory neuronal death, although this hypothesis remains to be proved in future studies.

Abstract
We examined the actions of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3) on human monocytes, using a serum-free culture system. GM-CSF and IL-3 did not promote the differentiation of monocytes into macrophages but rather into cells with a phenotype compatible with that of immature dendritic cells (DCs). The addition of fetal bovine serum to serum-free cultures with GM-CSF or IL-3 restored the differentiation of monocytes into macrophages. Cells generated with GM-CSF or IL-3 elicited phagocytic activity. Cells generated in the presence of GM-CSF or IL-3, followed by the addition of tumor necrosis factor-alpha, displayed a phenotype of mature DCs, and primed and stimulated immunogenic peptide-specific T lymphocytes. Surprisingly, GM-CSF and IL-3 inhibited macrophage colony-stimulating factor (M-CSF)-dependent differentiation of monocytes into macrophages and induced differentiation into immature DCs. We asked if the inhibition of M-CSF-dependent differentiation into macrophages by GM-CSF or IL-3 was associated with the expression of M-CSF receptors (M-CSFR). GM-CSF or IL-3 down-regulated the expression of M-CSFR. These data demonstrate that GM-CSF and IL-3 primarily support the differentiation of monocytes into DCs and inhibit M-CSF-dependent differentiation into macrophages by suppressing the expression of M-CSFR, thereby promoting differentiation into DCs.

Abstract
It is generally recognized that postmitotic neutrophils give rise to polymorphonuclear neutrophils alone. We obtained evidence for a lineage switch of human postmitotic neutrophils into macrophages in culture. When the CD15+CD14- cell population, which predominantly consists of band neutrophils, was cultured with granulocyte macrophage-colony-stimulating factor, tumor necrosis factor-alpha, interferon-gamma, and interleukin-4, and subsequently with macrophage colony-stimulating factor alone, the resultant cells had morphologic, cytochemical, and phenotypic features of macrophages. In contrast to the starting population, they were negative for myeloperoxidase, specific esterase, and lactoferrin, and they up-regulated nonspecific esterase activity and the expression of macrophage colony-stimulating factor receptor, mannose receptor, and HLA-DR. CD15+CD14- cells proceeded to macrophages through the CD15-CD14- cell population. Microarray analysis of gene expression also disclosed the lineage conversion from neutrophils to macrophages. Macrophages derived from CD15+CD14- neutrophils had phagocytic function. Data obtained using 3 different techniques, including Ki-67 staining, bromodeoxyuridine incorporation, and cytoplasmic dye labeling, together with the yield of cells, indicated that the generation of macrophages from CD15+CD14- neutrophils did not result from a contamination of progenitors for macrophages. Our data show that in response to cytokines, postmitotic neutrophils can become macrophages. This may represent another differentiation pathway toward macrophages in human postnatal hematopoiesis.

Abstract
The purpose of this study was to clarify the effects of mirimostim (macrophage colony-stimulating factor; M-CSF) on immunological functions after chemotherapy. The percentage of natural killer (NK) cells in peripheral blood mononuclear cells (PBMCs), NK cell activity, T-helper cell 1/T-helper cell 2 (Th1/Th2) ratio, and superoxide anion production by granulocytes (granulocyte function) were measured as immunological parameters before and after chemotherapy in 44 patients with primary ovarian cancer who received at least three consecutive courses of postoperative chemotherapy. Patients were observed during the first course of chemotherapy, and 39 patients who presented grade III or IV neutropenia were entered into this study and randomly allocated to an M-CSF-administered group (group 1; 19 patients) and a non-M-CSF-administered group (group 2; 20 patients) for the second course. For the third course, a crossover trial was conducted. In the observation period, chemotherapy significantly impaired the immunological parameters. In particular, those parameters were significantly decreased at day 14 compared to the level before chemotherapy. The values of the parameters of group 1 were significantly higher than those of group 2. In the course of chemotherapy during which M-CSF was administered, 19 of the 39 patients presented grade IV neutropenia, and received granulocyte colony-stimulating factor (G-CSF) between days 7 and 14. We compared the changes of those immunological parameters in the M-CSF alone group and the M-CSF + G-CSF group, and found that the concomitant use of G-CSF did not further improve the parameters. These results indicate that chemotherapy markedly impaired the immunological functions, and that the administration of M-CSF significantly improved the impaired immunological functions.

Abstract
Interleukin 8 (IL-8) is a member of the alpha chemokine family of cytokines originally identified as a neutrophil chemoattractant. Recently, we reported that elevated levels of IL-8, but not parathyroid hormone-related protein (PTHrP), correlated with increased bone metastasis in a population of human breast cancer cells. We hypothesized that IL-8 expression by breast cancer cells would either indirectly influence osteoclastogenesis via nearby stromal cells or directly influence osteoclast differentiation and activity. In the present study, we investigated the role of IL-8 in the process of osteoclast formation and bone resorption, which is associated with metastatic breast cancer. The addition of recombinant human (rh) IL-8 (10 ng/ml) to cultures of stromal osteoblastic cells stimulated both RANKL mRNA expression and protein production, with no effect on the expression of osteoprotegerin. In addition, rhIL-8 also directly stimulated the differentiation of human peripheral blood mononuclear cells into bone-resorbing osteoclasts. In these cultures, IL-8 was able to stimulate human osteoclast formation even in the presence of excess (200 ng/ml) RANK-Fc. The effect of IL-8 on osteoclasts and their progenitors was associated with the cell surface expression of the IL-8-specific receptor (CXCR1) on the cells. These results demonstrate a direct effect of IL-8 on osteoclast differentiation and activity. Together, these data implicate IL-8 in the osteolysis associated with metastatic breast cancer.

Abstract
To characterize recombinant human macrophage-colony stimulating factor (rhM-CSF)-associated thrombocytopenia (TCP), in vivo studies were performed in dogs, including the biodistributions and recoveries of radiolabelled autologous and allogeneic platelets. rhM-CSF induced a reversible, dose-dependent decrease in platelet counts. The number of megakaryocytes in spleen and marrow of rhM-CSF-treated dogs was increased two to threefold. Recoveries of allogeneic platelets transfused from rhM-CSF-treated donors into tolerized recipients (n = 3) were not significantly different from allogeneic baseline studies (93 +/- 10% of baseline values at 24 h and 90 +/- 1% at 40 h), whereas autologous platelets infused back into rhM-CSF-treated donors had decreased recoveries (45 +/- 2% of baseline values at 24 h, P = 0.03 and 20 +/- 4% at 40 h, P = 0.001). Platelet biodistribution studies showed increased accumulation of radiolabelled platelets over the spleens and livers of rhM-CSF-treated dogs. Histochemistry showed increased levels of platelet-specific antigen (CD41; glycoprotein IIb) associated with Kupffer cells. The sensitivity of platelets from rhM-CSF-treated dogs to activation from thrombin, as measured by expression of P-selectin (CD62P), was not significantly different when compared with baseline studies (P = 0.18; n = 4). These results support the concept that rhM-CSF induces an activation of the monocyte-macrophage system (MMS), which causes a reversible TCP in a dog model.

Abstract
Chronic inflammatory demyelinating polyneuropathy (CIDP) is a slowly progressive or recurrent neuropathy accompanied by infiltration of macrophages in the peripheral nerves. Macrophage colony-stimulating factor (M-CSF) and monocyte chemoattractant protein-1 (MCP-1) are a macrophage-related cytokine and chemokine, respectively. Although, intravenous immunoglobulin (IVIg) infusion therapy has been used for treating CIDP patients, not all CIDP patients have responded to IVIg infusion therapy. To determine the mechanisms of the action of IVIg, we examined serum M-CSF and MCP-1 levels during and after IVIg infusion therapy in 19 CIDP patients treated with IVIg (0.4 g/kg/day for 5 days). Ten of the 19 patients (52.6%) responded to IVIg therapy. Both M-CSF and MCP-1 concentrations in IVIg responders were significantly higher on day 1 postinfusion than those in nonresponders, but decreased to their pretreatment values on day 5 postinfusion. The results suggest that immunomodulation through M-CSF and MCP-1 is involved in the mechanisms underlying the effect of IVIg infusion therapy in CIDP patients.

Abstract
Ectothermic vertebrates exhibit a diverse array of adult pigment patterns. A common element of these patterns is alternating dark and light stripes each comprising different classes of neural crest-derived pigment cells. In the zebrafish, Danio rerio, alternating horizontal stripes of black melanophores and yellow xanthophores are a prominent feature of the adult pigment pattern. In fms mutant zebrafish, however, xanthophores fail to develop and melanophore stripes are severely disrupted. fms encodes a type III receptor tyrosine kinase expressed by xanthophores and their precursors and is the closest known homologue of kit, which has long been studied for roles in pigment pattern development in amniotes. In this study we assess the cellular and temporal requirements for Fms activity in promoting adult pigment pattern development. By transplanting cells between fms mutants and either wild-type or nacre mutant zebrafish, we show that fms acts autonomously to the xanthophore lineage in promoting the striped arrangement of adult melanophores. To identify critical periods for fms activity, we isolated temperature sensitive alleles of fms and performed reciprocal temperature shift experiments at a range of stages from embryo to adult. These analyses demonstrate that Fms is essential for maintaining cells of the xanthophore lineage as well as maintaining the organization of melanophore stripes throughout development. Finally, we show that restoring Fms activity even at late larval stages allows essentially complete recovery of xanthophores and the development of a normal melanophore stripe pattern. Our findings suggest that fms is not required for establishing a population of precursor cells during embryogenesis but is required for recruiting pigment cell precursors to xanthophore fates, with concomitant effects on melanophore organization.

Abstract
Sterol 27-hydroxylase has been suggested to be involved in an alternative pathway for the elimination of cholesterol from macrophages and early atherosclerotic lesions. We have previously shown that human lung macrophages as well as monocyte-derived macrophages have a relatively high activity of sterol 27-hydroxylase (CYP27). This enzyme converts intracellular cholesterol into 27-hydroxycholesterol and cholestenoic acid that flux from cultured cells into the medium. It is shown here that human monocytes have very low CYP27 activity and CYP27 mRNA levels. During differentiation into macrophages, both CYP27 activity and CYP27 mRNA levels increase markedly after 4 days of culture in serum-free medium. Addition of macrophage-colony stimulating factor had no significant effect on the induction and addition of fetal calf serum had an inhibitory effect. Cholesterol synthesis was found to be a critical factor for the production of 27-oxygenated products by the macrophages cultured in serum-free medium. The increased capacity of the differentiated cells to eliminate intracellular cholesterol is of interest and supports the contention that CYP27 is an antiatherogenic factor.

Abstract
We conducted a comparative study of NK1.1+ cells in spleen and bone marrow and the effects of administration of M-CSF on them. Administration of M-CSF to mice increased the number of NK1.1+ cells in spleen but not in bone marrow. The NK1.1+ cells in spleen (Spl-NK1.1) and bone marrow (BM-NK1.1) were purified by magnetic cell sorter. Their cell surface markers and functions were then examined. The percentage of Mac-1 antigen-positive cells (and F4/80 antigen-positive cells) was higher among BM-NK1.1 than Spl-NK1.1. Moreover, the administration of M-CSF increased the number of Mac-1 and F4/80 antigen-positive cells in both Spl-Nk1.1 and BM-NK1.1. The functions (cytolytic activity and IFN-gamma production) of Spl-NK1.1 and BM-NK1.1 were the same and were enhanced by the administration of M-CSF. But Spl-NK1.1 produced more IFN-gamma than BM-NK1.1 when M-CSF was administered. BM-NK1.1 showed a greater proliferative response to IL-2 than Spl-NK1.1. Administration of M-CSF augmented this response. BM-NK1.1 proliferated in response to IL-4 and IL-15, but Spl-NK1.1 responded only slightly. However, administration of M-CSF stimulated Spl-NK1.1 to respond to these cytokines. Both Spl-NK1.1 and BM-NK1.1 showed only a weak response to M-CSF in vitro. But the expression of c-fms antigen (M-CSFR) increased after the M-CSF injections in vivo. These results suggested that there are phenotypical and functional differences between Spl-NK1.1 and BM-NK1.1. The administration of M-CSF led to an accumulation of NK1.1+ cells which were mobilized from bone marrow in spleen.

Abstract
The active vitamin D(3)-metabolite 1,25(OH)(2)D(3) inhibits the interleukin 4/granulocyte-macrophage colony-stimulating factor (IL-4/GM-CSF)-induced differentiation of human monocytes into dendritic cells without altering survival. Colony-stimulating factor 1 (CSF-1) is an important survival factor for cells of the monocytic lineage. We therefore investigated whether the inhibitory activity of 1,25(OH)(2)D(3) is paralleled by a regulation of CSF-1 and its receptor. Purified human monocytes were cultured together with IL-4/GM-CSF in the presence of 1,25(OH)(2)D(3), its analogue tacalcitol, the low-affinity vitamin D receptor ligand 24,25(OH)(2)D(3), or the solvent ethanol for up to 5 days. Expression of CSF-1, CSF-1R, and GM-CSF mRNA was measured by RT-PCR. Protein secretion for CSF-1 was measured by ELISA, expression of CSF-1R by flow cytometry. The results showed that 1,25(OH)(2)D(3) and tacalcitol significantly up-regulated CSF-1 mRNA-expression and protein secretion in a dose-dependent manner. The effect of 1,25(OH)(2)D(3) occurred already after 1h of pre-treatment. In contrast, CSF-1R mRNA- and cell surface-expression was down-regulated simultaneously. The solvent ethanol and 24,25(OH)(2)D(3) were without effect. GM-CSF mRNA expression was not modulated in 1,25(OH)(2)D(3)-treated cells. These data point towards a distinct and specific regulation of CSF-1 and its receptor by 1,25(OH)(2)D(3) and its analogue tacalcitol in human monocytes which parallels the inhibition of differentiation into dendritic cells without altering survival.

Abstract
We have cloned and characterized a novel gene from both human and mouse that encodes a new member of the immunoglobulin superfamily. The gene is preferentially expressed in both brain and testis, and hence, termed BT-IgSF (brain- and testis-specific immunoglobulin superfamily). The predicted protein consists of V-type and C2-type immunoglobulin domains as well as a hydrophobic signal sequence, a single transmembrane region, and a cytoplasmic domain. Human BT-IgSF protein (431 amino acids) is 88% identical to the mouse protein (428 amino acids) and both show significant homology to coxsackie and adenovirus receptor (CAR) and endothelial cell-selective adhesion molecule (ESAM). We examined the expression of BT-IgSF with various cultured cells and found that the gene was expressed in both neurons and glial cells in vitro. Furthermore, the expression was preferentially detected in pyramidal cell layers of the dentate gyrus and hippocampus and in commissure fibers of the corpus callosum, in brain tissue sections examined. These findings suggest that BT-IgSF plays a role in the development or function of the central nervous system.

Abstract
Macrophages have various functions and play a critical role in host defense and the maintenance of homeostasis. However, macrophages are heterogeneous and exhibit a wide range of phenotypes with regard to their morphology, cell surface antigen expression, and function. When blood monocytes are cultured in medium alone in vitro, monocytes die, and colony-stimulating factors (CSFs) such as macrophage (M)-CSF or granulocyte-macrophage (GM)-CSF are necessary for their survival and differentiation into macrophages. However, M-CSF-induced monocyte-derived macrophages (M-Mphi) and GM-CSF-induced monocyte-derived macrophages (GM-Mphi) are distinct in their morphology, cell surface antigen expression, and functions, including Fcgamma receptor mediated-phagocytosis, H2O2 production, H2O2 sensitivity, catalase activity, susceptibility to human immunodeficiency virus type 1 and Mycobacterium tuberculosis, and suppressor activity. The characteristics of GM-Mphi resemble those of human alveolar macrophages.

Abstract
The receptor for macrophage colony-stimulating factor (M-CSF) is expressed in monocytes/macrophages and their progenitor cells and stimulates both the growth and development of the blood-cell lineage. Although the specific components positively regulating M-CSF receptor signaling have been relatively well defined, it is now clear that important mechanisms to control the signaling cascades also exist. This review discusses the most recent results concerning the negative regulatory molecules for M-CSF receptor signaling. In particular, we focus on negative molecules for both proliferation of monocytes/macrophages and differentiation into mature cells.

Abstract
The purpose of this study was to evaluate the effect of coadministration of macrophage colony-stimulating factor (M-CSF) and interferon-alpha (IFN-alpha) on NK1.1(+) cells in mice. Administration of M-CSF, but not IFN-alpha, increased the number of NK1.1(+) cells and CD11b(+) cells in spleen and blood. Coadministration of the two agents induced a greater increase in NK1.1(+) cells than did administration of M-CSF alone. Administration of M-CSF or IFN-alpha augmented the clearance activity of Yac-1 cells in lung, and coadministration of these agents further augmented this effect. The combination of M-CSF and IFN-alpha effectively reduced the formation of tumor nodules in lung and liver in an experimental metastasis model using B16 melanoma. The combination of M-CSF and IFN-alpha induced the increase and activation of NK1.1(+) cells more than either agent alone. These effects may contribute to the antimetastatic reaction by NK1.1(+) cells in vivo.

Abstract
Plasma macrophage colony-stimulating factor (M-CSF) levels were measured in 13 haematologic patients treated with autologous peripheral blood stem cell transplantation (PBSCT). Six of the patients showed an increase in M-CSF peak levels (>3000 pg/ml) during the conditioning and stem cell infusion period. The peak levels of M-CSF in this phase correlated with thrombomodulin levels, indicating the endothelial origin of plasma M-CSF. However, the M-CSF levels were not influenced by TNFalpha. More patients with high M-CSF levels (>5000 pg/ml) suffered from organ failure than those with lower M-CSF levels. These results suggest that high M-CSF levels may correlate with cellular or organ damage in patients treated with PBSCT.

Abstract
The study of vertebrate pigment patterns is a classic and enduring field of developmental biology. Knowledge of pigment pattern development comes from a variety of systems, including avians, mouse, and more recently, the zebrafish (Danio rerio). Recent analyses of the mechanisms underlying the development of the neural crest-derived pigment cell type common to all vertebrates, the melanocyte, have revealed remarkable similarities and several surprising differences between amniotes and zebrafish. Here, we summarize recent advances in the study of melanocyte development in zebrafish, with reference to human, mouse, and avian systems. We first review melanocyte development in zebrafish and mammals, followed by a summary of the molecules known to be required for their development. We then discuss several relatively unaddressed issues in vertebrate pigment pattern development that are being investigated in zebrafish. These include determining the relationships between genetically distinct classes of melanocytes, characterizing and dissecting melanocyte stem cell development, and understanding how pigment cells organize into a patterned tissue. Further analysis of zebrafish pigment pattern mutants as well as new generations of directed mutant screens promise to extend our understanding of pigment pattern morphogenesis.

Abstract
We investigated tyrosine phosphorylation of proteins in primary human leukemic cells stimulated by macrophage colony-stimulating factor (M-CSF) in 60 patients with acute myeloid leukemia (AML) and 5 patients with chronic myelomonocytic leukemia and compared the findings for leukemic cells with those of normal human monocytes and bone marrow immature hematopoietic cells. M-CSF induced tyrosine phosphorylation of p140-200, p110, p60, p44, and p42 frequently, and that of p95 and p55 less frequently, in primary myeloid leukemic cells, whereas M-CSF-induced phosphorylation of proteins was not detected in the normal human hematopoietic cells tested. Of these phosphoproteins, p140-200 was phosphorylated in all patients who responded to M-CSF and was considered to be almost identical to Fms, a product of the c-fms proto-oncogene. M-CSF-induced tyrosine phosphorylation was observed frequently (89%) in AML of French-American-British class M4 and infrequently in all other subtypes of AML, including M5. In chronic myelomonocytic leukemia, M-CSF-induced protein phosphorylation was prominent in blast crisis but was not detected in the chronic phase. Both bone marrow immature cells and mature monocytes showed low responsiveness to M-CSF. These findings for responsiveness to M-CSF were correlated with the amount of Fms in each type of cell. We also identified tyrosine phosphorylation of Vav, Shc, and extracellular signal-regulated kinase by M-CSF in some cases. These findings clarified an M-CSF-specific pattern of protein tyrosine phosphorylation and the responsiveness to M-CSF of primary human myeloid cells. Particularly, enhanced phosphorylation responses to M-CSF and increased amounts of Fms protein were observed in restricted human hematopoietic cells with a premature myelomonocytic character.

Abstract
Kostmann syndrome, severe congenital neutropenia, is often associated with life-threatening bacterial infections. A 5-year-old girl with Kostmann syndrome developed pulmonary abscesses. She was refractory to granulocyte colony-stimulating factor and antibiotics. She underwent unrelated HLA-matched BMT. Myeloablative conditioning consisted of 12-Gy TBI with lung shielding, antithymocyte globulin, etoposide, and cyclophosphamide. After successful engraftment, the pulmonary abscesses resolved by day 75 post-transplant. Although the option of transplantation is not established in the setting of unrelated HLA-matched BMT in Kostmann syndrome, this case may provide useful information. Furthermore, pre-transplant pulmonary bacterial abscesses may not be a contraindication for BMT in some patients with Kostmann syndrome.

Abstract
A 67-year-old woman was treated for acute myelogenous leukemia with trilineage dysplasia (AML-TLD) by combination chemotherapy with cytarabine, aclarubicin plus macrophage colony-stimulating factor (M-CSF) (referred to as CAM therapy). Complete remission was achieved after two courses of CAM therapy. After coculture of her bone marrow mononuclear cells with M-CSF in vitro, differentiation of leukemic cells into macrophages with apoptotis was observed. This case confirms an earlier report that an effect of M-CSF inducible by differentiation with apoptotic phenomena, against human leukemic cells was shown both in vitro and in vivo when achieving complete remission.

Abstract
Human myeloid cells include hematopoietic cells at various stages of differentiation, from immature myeloid cells to mature phagocytes. Normal immature myeloid cells undergo differentiation concomitantly with proliferation in response to hematopoietic growth factors, and terminally differentiated cells, ie, mature phagocytes, exert their effector functions and then die a natural death via apoptosis. However, leukemic myeloid cells are induced to differentiate with growth suppression by several inducers, such as retinoic acid. This review describes differentiation, apoptosis, and functionality of human myeloid cells. mainly focusing on the intracellular signaling mechanism. The signal transduction system for these biological events of the life cycle of myeloid cells has recently been studied, and several characteristics have been elucidated. First, the signaling pathway for myeloid differentiation is mainly focused in the mitogen-activated protein kinases, such as extracellular signal-regulated kinase and p38, and transcriptional factors such as the signal transducers and activators of transcription PU.1 and CCAAT enhancer binding protein. Second, the signaling mechanism for myeloid cell apoptosis is fundamentally identical to that found in other cells. Caspases, caspase-activated DNase, and mitochondrial molecules such as apoptosis-inducing factor have been reported to be important, and mitogen-activated protein kinases such as p38 appear to be less important. Finally, p38 and phosphatidylinositol 3-kinase play critical roles in the signaling cascade for functional activation of mature phagocytes. The reasons why the same signaling molecules play distinct roles according to the differentiation stage and biological event await future clarification.
