Abstract
Besides massive expression in inflammatory pleural effusions, inflammatory markers are also present in cancer-induced pleural effusions. Recent advances in cancer biology point to a role of inflammatory signaling in cancer and encourage reconsidering the diagnostic and prognostic value of inflammatory markers. Here an attempt was made to relate protein levels of inflammatory markers to underlying malignant processes in the pleural space. Pleural effusions from lung cancer patients (n=116) were subjected to a multifactorial analysis covering 13 inflammatory markers. The composition of tumor-associated effusions was compared with that of parainflammatory pleural effusions (n=30), transudates (n=18), and serum values, and evaluated in relation to cancer origin, histology, cytology, pleural involvement, treatment history, and survival time. Inflammatory markers were significantly expressed in pleural effusions of paraneoplastic origin when compared to transudates and most serum levels. Values in pleura-invading and metastatic tumor-associated effusions were typically higher than those of other tumors. Many markers correlated negatively with survival, most prominently IL-8 (r=–0.36, p=0.001) and VEGF (r=–0.35, p=0.001). It appears that most inflammatory markers are highly expressed in tumor-associated pleural effusions, reflecting to some extent tumor origin and localization. Despite the lower efficacy of inflammatory markers in the differentiation between exudative pleural effusions, some inflammatory markers may represent potential prognostic markers of malignant processes in the pleural space.

Association of intercellular adhesion molecule-1 single nucleotide polymorphisms with hepatocellular carcinoma susceptibility and clinicopathologic development. Tumour Biol 2015; 37:2067-74. [PMID: 26341495 DOI: 10.1007/s13277-015-3992-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2015] [Accepted: 08/25/2015] [Indexed: 12/19/2022] Open
Abstract
Intercellular adhesion molecule-1 (ICAM-1) is a human protein encoded by the ICAM-1 gene and is typically expressed on endothelial cells and immune cells. ICAM-1 is associated with episode, growth, invasion, and metastasis of hepatocellular carcinoma (HCC). However, the association between ICAM-1 genetic variants and the risk of HCC is undetermined. In this study, we investigated the potential associations of ICAM-1 single nucleotide polymorphisms (SNPs) with susceptibility to HCC and its clinicopathological characteristics. A total of 918 participants, including 613 controls participants and 305 patients with HCC, were selected for the analysis of ICAM-1 SNPs (rs3093030, rs5491, rs281432, and rs5498) by using real-time PCR genotyping. After adjusting for covariants of age, sex, and alcohol consumption, 125 smoker patients with HCC carrying at least one G genotype (AG and GG) in rs5498 were observed to have a higher HCC risk compared with 231 smoker control participants carrying the wild-type allele AA (adjusted odds ratio (AOR), 1.713; 95 % confidence interval (CI), 1.091-2.690; P = 0.019). However, patients who possess at least one polymorphic allele of rs5498 are less prone to develop vascular invasive (AOR, 0.309; 95 % CI, 0.103-0.926; P = 0.036). The results suggest that the genetic polymorphism in ICAM-1 rs5498 SNPs with genotype AG and GG is associated with HCC risk among smokers. Moreover, gene and environment interactions of ICAM-1 rs5498 polymorphisms might alter susceptibility to liver cancer. Therefore, ICAM-1 rs5498 may serve as a marker to predict the vascular invasion risk in smoker patients with HCC.

Abstract
Spatially localized proteolysis represents an elegant means by which neuronal activity dependent changes in synaptic structure, and thus experience dependent learning and memory, can be achieved. In vitro and in vivo studies suggest that matrix metalloproteinase and adamalysin activity is concentrated at the cell surface, and emerging evidence suggests that increased peri-synaptic expression, release and/or activation of these proteinases occurs with enhanced excitatory neurotransmission. Synaptically expressed cell adhesion molecules (CAMs) could therefore represent important targets for neuronal activity-dependent proteolysis. Several CAM subtypes are expressed at the synapse, and their cleavage can influence the efficacy of synaptic transmission through a variety of non-mutually exclusive mechanisms. In the following review, we discuss mechanisms that regulate neuronal activity-dependent synaptic CAM shedding, including those that may be calcium dependent. We also highlight CAM targets of activity-dependent proteolysis including neuroligin and intercellular adhesion molecule-5 (ICAM-5). We include discussion focused on potential consequences of synaptic CAM shedding, with an emphasis on interactions between soluble CAM cleavage products and specific pre- and post-synaptic receptors.

Abstract
Ectodomain shedding of transmembrane precursor proteins generates numerous life-essential molecules, such as epidermal growth factor receptor ligands. This cleavage not only releases the regulatory growth factor, but it is also the required first step for the subsequent processing by γ-secretase and the release of gene regulatory intracellular fragments. Signaling within the cell modifies the cytoplasmic tails of substrates, a step important in starting the specific and regulated cleavage of a large number of studied substrates. Ectodomain cleavage occurs, however, on the outside of the plasma membrane and is carried out by membrane-bound metalloproteases. How the intracellular domain modification communicates with the ectodomain of the substrate to allow for cleavage to occur is unknown. Here, we show that homodimerization of a cluster-of-differentiation-44 or of pro-neuregulin-1 monomers represents an essential pre-condition for their regulated ectodomain cleavage. Both substrates are associated with their respective metalloproteases under both basal or cleavage-stimulated conditions. These interactions only turn productive by specific intracellular signal-induced intracellular domain modifications of the substrates, which in turn regulate metalloprotease access to the substrates' ectodomain and cleavage. We propose that substrate intracellular domain modification induces a relative rotation or other positional change of the dimerization partners that allow metalloprotease cleavage in the extracellular space. Our findings fill an important gap in understanding substrate-specific inside-out signal transfer along cleaved transmembrane proteins and suggest that substrate dimerization (homo- or possibly heterodimerization) might represent a general principle in ectodomain shedding.

Abstract
Intercellular adhesion molecule (ICAM)-1, a cell adhesion molecule, is reportedly overexpressed in several cancers and may contribute to tumorgenesis and metastasis. The current study explored the effect of ICAM-1 gene polymorphisms on the susceptibility of developing urothelial cell carcinoma (UCC) and the clinicopathological status. A total of 558 participants, including 279 healthy people and 279 patients with UCC, were recruited for this study. Four single-nucleotide polymorphisms of the ICAM-1 gene were assessed by a real-time polymerase chain reaction with the TaqMan assay. After adjusting for other covariants, the individuals carrying at least one G allele at ICAM-1 rs5498 had a 1.603-fold risk of developing UCC than did wild-type (AA) carriers. Furthermore, UCC patients who carried at least one G allele at rs5498 had a higher invasive stage risk (p < 0.05) than did patients carrying the wild-type allele. In conclusion, the rs5498 polymorphic genotypes of ICAM-1 might contribute to the prediction of susceptibility to and pathological development of UCC. This is the first study to provide insight into risk factors associated with ICAM-1 variants in carcinogenesis of UCC in Taiwan.

Abstract
UNLABELLED Significant challenges remain in targeting drugs to diseased vasculature; most important being rapid blood flow with high shear, limited availability of stable targets, and heterogeneity and recycling of cellular markers. We developed nanoparticles (NPs) to target degraded elastic lamina, a consistent pathological feature in vascular diseases. In-vitro organ and cell culture experiments demonstrated that these NPs were not taken up by cells, but instead retained within the extracellular space; NP binding was proportional to the extent of elastic lamina damage. With three well-established rodent models of vascular diseases such as aortic aneurysm (calcium chloride mediated aortic injury in rats), atherosclerosis (fat-fed apoE-/- mice), and vascular calcification (warfarin + vitamin K injections in rats), we show precise NPs spatial targeting to degraded vascular elastic lamina while sparing healthy vasculature when NPs were delivered systemically. Nanoparticle targeting degraded elastic lamina is attractive to deliver therapeutic or imaging agents to the diseased vasculature. FROM THE CLINICAL EDITOR This novel work focuses on nanoparticle targeting of degraded elastic lamina in a variety of diseases, including atherosclerosis, vascular calcification, and aneurysm formation, and demonstrates the feasibility to deliver therapeutic or imaging agents to the diseased vasculature.

Abstract
We studied the effect of type 1 herpes simplex infection on the production of innate immunity mediators in human vascular endothelial cells in culture. It was found that production of anti-inflammatory cytokines IL-1β, IL.6, and TNF-α in infected cultures depended on the level of their spontaneous production, while IL-8 production was suppressed irrespective of its spontaneous level. Shedding of cell adhesion molecules of early (P-selectin and E-selectin) and late (PECAM-1 and VE-cadherin) phases of leukocyte recruitment depended on individual capacity of human vascular endothelial cell cultures to maintain reproduction of type 1 herpes simples virus. The production of vasodilator NO and vasoconstrictor endothelin-1 by infected cultures also depended on spontaneous synthesis of this transmitter by non-infected cultures.

Abstract
Understanding African Trypanosomiasis (AT) host-pathogen interaction is the key to an "anti-disease vaccine", a novel strategy to control AT. Here we provide a better insight into this poorly described interaction by characterizing the activation of a panel of endothelial cells by bloodstream forms of four African trypanosome species, known to interact with host endothelium. T. congolense, T. vivax, and T. b. gambiense activated the endothelial NF-κB pathway, but interestingly, not T. b. brucei. The parasitic TS (trans-sialidases) mediated this NF-κB activation, remarkably via their lectin-like domain and induced production of pro-inflammatory molecules not only in vitro but also in vivo, suggesting a considerable impact on pathogenesis. For the first time, TS activity was identified in T. b. gambiense BSF which distinguishes it from the subspecies T. b. brucei. The corresponding TS were characterized and shown to activate endothelial cells, suggesting that TS represent a common mediator of endothelium activation among trypanosome species with divergent physiopathologies.

Abstract
BACKGROUND In Taiwan, oral cancer has causally been associated with environmental carcinogens. Intercellular adhesion molecule (ICAM)-1, a cell adhesion molecule with a key role in inflammation and immunosurveillance, was implicated in carcinogenesis by facilitating instability in the tumor environment. The current study explored the combined effect of ICAM-1 gene polymorphisms and exposure to environmental carcinogens on the susceptibility of developing oral squamous cell carcinoma (OSCC) and the clinicopathological characteristics of the tumors. METHODOLOGY AND PRINCIPAL FINDINGS Four single-nucleotide polymorphisms (SNPs) of the ICAM-1 gene from 595 patients with oral cancer and 561 non-cancer controls were analyzed by a real-time PCR. We found that the ICAM-1 rs5498 polymorphism and the TAGG or TACG haplotype of 4 ICAM-1 SNPs (rs3093030, rs5491, rs281432, and rs5498) combined were associated with oral-cancer susceptibility. Among 727 smokers, ICAM-1 polymorphisms carriers with the betel-nut chewing habit had a 27.49-36.23-fold greater risk of having oral cancer compared to ICAM-1 wild-type (WT) carriers without the betel-nut chewing habit. Among 549 betel-nut chewers, ICAM-1 polymorphisms carriers who smoked had a 9.93-14.27-fold greater risk of having oral cancer compared to those who carried the WT but did not smoke. Finally, patients with oral cancer who had at least 1 T allele of ICAM-1 rs5491 or 1 G allele of rs281432 were at lower risk of developing an advanced clinical stage (III/IV) (p<0.05), compared to those patients with AA or CC homozygotes. CONCLUSIONS Our results suggest that the ICAM-1 rs5498 SNP and either of 2 haplotypes of 4 SNPs combined have potential predictive significance in oral carcinogenesis. Gene-environment interactions of ICAM-1 polymorphisms, smoking, and betel-nut chewing might alter oral-cancer susceptibility. ICAM-1 rs5491 and rs281432 may be applied as factors to predict the clinical stage in OSCC patients.

Abstract
BACKGROUND Prognosis of peritoneal surface malignancies is influenced by the adequacy of surgical and chemotherapeutic treatment and by tumor spread at the time of diagnosis. By promoting morphological changes in the mesothelium, inflammatory cytokines reflect tumor biology and could be evaluated as biomarkers. Our objective was to evaluate intraperitoneal levels of IL-6, IL-8, IL-10, TNF-alpha, and sICAM in patients with pseudomyxoma peritonei and peritoneal mesothelioma. METHODS Serum and peritoneal fluid samples were prospectively collected in patients managed for peritoneal surface malignancies including pseudomyxoma peritonei (PMP), mesotheliomas, and other rare primitive peritoneal cancers (cancer group) and patients who underwent intraperitoneal laparoscopic surgical procedures for benign diseases (noncancer group). Samples were analyzed for IL-6, IL-8, IL-10, TNF-alpha, and sICAM concentrations. Correlations were assessed with tumor spread related clinical scores. RESULTS In both patient groups, intraperitoneal cytokine levels were higher than serum levels. Cancer patients had significantly higher intraperitoneal cytokine levels than noncancer patients. Peritoneal levels tended to increase in cancer patients with free tumor cells in peritoneal fluid. They were significantly higher in patients with tumor implants ≥2 cm and/or patients with peritoneal carcinomatosis index (PCI) >19. Furthermore, patients with malignant pseudomyxoma peritonei (grades II and III) had higher levels than patients with nonmalignant disease (grade I). CONCLUSIONS Assessment of intraperitoneal IL-6, IL-8, IL-10, TNF-alpha, and sICAM levels can be performed in patients with peritoneal surface malignancies. They can be considered as both diagnostic and prognostic biomarkers that could be used as useful adjuncts for therapeutic decision making.

Abstract
There is a universally recognized need to identify new, reliable markers of inflammation that can aid in the rapid diagnosis of orthopaedic joint prosthesis infections (OJP-Is). Since prompt diagnosis is key to timely intervention in the course of infection, different molecules have been studied. In this study, we examined three groups of patients: those with prosthesis infection, those without infection, and a third group with previous infection in whom the infection had been cleared. Four presumed markers of infection were tested: procalcitonin (PCT); C-reactive protein (CRP); interleukin-6 (IL-6); and soluble intercellular adhesion molecule-1 (sICAM-1). The results showed that PCT cannot be considered as a good marker of periprosthetic infection as no statistically significant difference in serum PCT levels emerged between patients with infection and controls or patients without infection. In contrast, both sICAM-1 and CRP may be considered as good markers of infection, as measurement of their levels allowed us to distinguish between patients with and without infection, and between patients with infection and those with previous infection, since marker levels quickly returned to baseline values after clearance of the infection. IL-6 was found to be a good marker for inflammation, as it distinguished between patients with infection and the other groups. In the patients with previous infection, the IL-6 values remained high versus the controls but lower and with a statistically significant difference versus the patients with infection. Further studies are needed to determine the cut-off value of IL-6 between patients with infection and those with previous infection.

Abstract
CD94/NKG2A is an inhibitory receptor expressed by NK cells and cytotoxic lymphocytes and, upon activation by HLA-E, downregulates the cytolytic activities of these cells thus representing a tumour immune escape mechanism. This study was aimed at assessing whether cytotoxic lymphocytes (CD8+) and NK cells from malignant pleural effusions have a deregulated expression of CD94/NKG2A. The expression of membrane CD94/NKG2A and perforin was evaluated by flow-cytometry in CD8+ and NK cells from pleural effusions and autologous peripheral blood of cancer (n=19) and congestive heart failure (CHF) (n=11) patients. Intracellular CD94/NKG2A expression was evaluated by flow-cytometry in pleural effusion CD8+ and NK cells from cancer patients (n=10). Cytotoxic activity against cancer cells exerted by pleural and autologous peripheral blood T lymphocytes from cancer patients was assessed by flow-cytometry assay. Pleural CD8+ from cancer patients showed a reduced expression of membrane CD94/NKG2A and perforin when compared to autologous peripheral blood and CHF pleural effusions. Reduced numbers of NK cells were present in pleural effusions from both cancer and CHF patients. Pleural NK from cancer patients showed a reduced expression of membrane CD94/NKG2A and perforin when compared to autologous peripheral blood. Pleural T lymphocytes from cancer patients exhibited a reduced cytotoxic activity against cancer cells when compared to autologous peripheral blood T lymphocytes. The intracellular expression of CD94/NKG2A in CD8+ and NK cells from cancer patients was higher than membrane expression. In conclusion, this study provides compelling evidences of new mechanisms underlying the reduced host defence against cancer within the pleural space.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease characterized by progressive airflow limitation and significant extrapulmonary (systemic) effects that lead to co-morbid conditions, though the pathomechanism of COPD is largely undetermined. Alveolar macrophages (AM) derived from peripheral monocytes (MO) appear to play a key role in initiating and/or sustaining disease progression. OBJECTIVES To identify disease- and cell type-specific gene expression profiles and potential overlaps in those in order to diagnose COPD, characterize its progression and determine the effect of drug treatment. METHOD Global gene expression analysis was used for primary screening in order to obtain expression signatures of AMs and circulating MOs of COPD patients and healthy controls. The results of microarray analyses of AMs (20 controls and 26 COPD patients) and MOs (16 controls and 22 COPD patients) were confirmed and validated by real-time quantitative polymerase chain reaction. RESULTS We have identified gene sets specifically associated with COPD in AMs and MOs. There were overlapping genes between the two cell types. Our data also show that COPD-specific gene expression signatures in AMs and MOs correlate with percent of predicted FEV(1). CONCLUSION Disease-specific and overlapping gene expression signatures can be defined in lung-derived macrophages and also in circulating monocytes. Some of the validated expression changes in both cell types correlate with lung function and therefore could serve as biomarkers of disease progression.

Abstract
OBJECTIVES Adhesion molecules are involved in the inflammatory response during acute pancreatitis (AP). We investigated the effect of dexamethasone (Dx) on intercellular adhesion molecule 1 (ICAM-1) expression during AP and its consequences on leukocyte recruitment and pancreatic damage. METHODS Acute pancreatitis was induced in rats by 3.5% sodium taurocholate for 3 hours and 6 hours. Dexamethasone (1 mg/kg) was administered either 30 minutes before or 1 hour after inducing AP. Messenger RNA ICAM-1 expression in pancreas and lung, membrane-bound ICAM-1 in acinar cells, and ICAM-1 plasma levels were analyzed. Histological examination of the pancreas and neutrophil infiltration in pancreas and lung were also measured. RESULTS Prophylactic and therapeutic administration of Dx down-regulated ICAM-1 expression in pancreas and lung from early AP. Dexamethasone given before AP reduced the pancreatic damage, but lung inflammation was not prevented. Therapeutic Dx treatment was ineffective in avoiding leukocyte recruitment into the pancreas and lung in rats with AP. High ICAM-1 concentration was found in plasma during AP, which was not reduced by Dx treatments. CONCLUSIONS Dexamethasone down-regulates ICAM-1 expression, but it does not completely prevent leukocyte recruitment during sodium taurocholate-induced AP.

Abstract
Increased vascular permeability and vascular leakage are characteristic pathological changes in hemorrhagic fever with renal syndrome (HFRS). Vascular endothelial cells are the main targets of Hantaan virus, the etiological agent of the severe form of HFRS. Hantaan virus can induce extensive damage of small blood vessels and capillaries. In vitro infection of human umbilical vein endothelial cells by Hantaan virus can induce the expression of intercellular adhesion molecule-1 (ICAM-1). The involvement of this molecule is implied in human HFRS. In the present study, serum-soluble ICAM-1 (sICAM-1) levels were determined and their relationships with the clinical course and disease severity were investigated in 112 HFRS patients and 30 healthy controls. The results showed that the serum levels of sICAM-1 in HFRS patients at fever, hypotensive, oliguric, and polyuric phases were significantly higher than those in controls (p < 0.001). However, no significant differences between the serum concentrations of sICAM-1 in the milder and more severe groups of patients were observed (p > 0.05). It is suggested that sICAM-1 was involved in the progression of HFRS. Time-dependent determinations of sICAM-1 levels may be indicators for the progression of disease, and elevated levels of sICAM-1 were not suggested to be correlated to disease severity.

Abstract
The changing face of tuberculosis, with epidemics fueled by HIV and urbanization in much of the world and a relative increase in the importance of latent tuberculosis as a source of cases in the more economically developed countries, has led to a demand for more robust, clinically applicable diagnostic tools. As a result, research aiming to identify biomarkers of Mycobacterium tuberculosis infection and disease has flourished. This article discusses the most recent findings of that work.

Abstract
PURPOSE OF REVIEW Every year, over 8 million people develop tuberculosis and nearly 1.8 million die from it, despite extensive vaccination and drug treatment programmes. It is increasingly recognized that the diagnosis of tuberculosis, which relies heavily on century-old techniques, is one of the weakest links in the chain of tuberculosis control, hampering not just treatment but also the development of new drugs and vaccines. As a result, recent years have seen the initiation of large-scale studies aiming to identify biomarkers of Mycobacterium tuberculosis infection and disease. This review discusses initial results and future prospects for that work. RECENT FINDINGS The key finding from recent work has been that no one factor seems able to explain the complex course of Mycobacterium tuberculosis infection. Multifactorial analyses have identified a variety of genes and proteins, mostly involved in bacterial persistence or host responses, that offer promise as biomarkers for different disease stages. SUMMARY The challenge now is to validate the suggested biomarkers being described and then reduce them to clinical practice. If this can be done, it offers the possibility of greatly improved clinical management of tuberculosis, allowing segregation of patients and contacts into appropriate treatment regimens.

Abstract
OBJECTIVE An anaerobic type of glycolysis exemplified by hyperproduction of the lactate dehydrogenase (LDH) subunit M has been detected in lung tumours, while a similar pattern has been found in concomitant pleural effusions (PE). The aim of this study was to verify the presence of the LDH subunit M in PEs of different aetiology and to compare its expression with markers of inflammation. MATERIAL AND METHODS LDH isoenzymes were estimated and the LDH5/LDH1 coefficient was calculated in paraneoplastic PEs (n = 99), including subgroups with a different tumour ultrastructure, origin and pleural involvement. The expression pattern was compared with parainflammatory PEs (n = 21), transudates (n = 16) and with the expression of 13 inflammatory markers in PEs. RESULTS The LDH5/LDH1 coefficient was higher in PEs associated with non-small-cell lung cancer (NSCLC) and with pleura-invading tumours, and lower in PEs of small-cell lung cancer and tumours without a confirmed pleural involvement. The LDH5/LDH1 coefficient positively correlated with uPA, IL-8, IL-10, sICAM, sVCAM, MPO and MMP-9. CONCLUSIONS In accordance with inflammatory markers, it appears that the expression of LDH and its isoenzymes in PEs reflects the host reaction in pleural space and, in NSCLC, may also feature the anaerobic phenotype of cancer cells.

Abstract
OBJECTIVE Fever is associated with improved survival, although its beneficial mechanisms are poorly understood. Previous studies indicate that the thermal element of fever augments lymphocyte migration across high endothelial venules (HEVs) of lymphoid organs by increasing the intravascular display of a gatekeeper trafficking molecule, intercellular adhesion molecule-1 (ICAM-1). Here, we evaluated the spatio-temporal relationship between the thermal induction of intravascular ICAM-1 and lymphocyte trafficking. METHODS Intravascular ICAM-1 density was quantified by immunofluorescence staining in mice exposed to fever-range whole-body hyperthermia (39.5+/-0.5 degrees C). ICAM-1-dependent lymphocyte trafficking was measured in short-term homing assays. RESULTS A linear relationship was observed between the duration of heat treatment and intravascular ICAM-1 density in HEVs with maximal responses requiring sustained (i.e., five hours) thermal stress. Circulating lymphocytes were found to sense incremental changes in ICAM-1 on HEVs, such that trafficking is proportional to the intravascular density of ICAM-1. We further identified a hydroxamate-sensitive shedding mechanism that restores ICAM-1 expression to homeostatic levels following the cessation of thermal stress. CONCLUSIONS The time-dependent response to thermal stress indicates that ICAM-1 density governs the efficiency of lymphocyte interactions with HEVs in vivo. These studies highlight the dynamic role of the microcirculation in promoting immune surveillance during febrile inflammatory responses.

Abstract
Leukotriene B(4) (LTB(4)) plays a crucial role in the recruitment of neutrophils into the pleural space. We identified for the first time the mechanisms by which LTB(4) interacts with mesothelial cells and recruits neutrophils in the pleural compartment. Primary pleural mesothelial cells express both the proinflammatory receptor for LTB(4) BLT2, and the anti-inflammatory receptor for LTB(4), PPARalpha. Parapneumonic pleural effusions highly increase BLT2 expression and, via BLT2 activation, increase the adhesion between mesothelial cells and neutrophils and the expression of ICAM-1 on mesothelial cells. The block of PPARalpha further increases both cell adhesion and ICAM-1 expression. BLT2 activation promotes the activation, on mesothelial cells, of STAT-1 but not the activation of NF-kappaB transcription factor. The increase of ICAM-1 expression is achieved via increased tyrosine phosphorylation activity since herbimycin, a tyrosine kinase inhibitor, reduces and since Na orthovanadate, a tyrosine phosphatase inhibitor, further increases ICAM-1 expression. This study demonstrates that pleural mesothelial cells, expressing both proinflammatory and anti-inflammatory LTB(4) receptors, are able to mount an integrated response to LTB(4) with a prevalence of BLT2 activities in the presence of an inflammatory milieu within the pleura.

Abstract
Breast cancer is the most common cancer among women, the second-most leading cause of women's death after lung cancer. ICAM-1 is a cell adhesion molecule that belongs to the Ig-superfamily, with a glycoprotein structure playing a key role in leukocyte recruitment into inflammatory sites, as well as in leukocyte activation and effector function. Proteolytic cleavage of ICAM-1 results in the formation of a soluble form, sICAM-1, which is present in low-serum levels in healthy individuals but becomes elevated in inflammatory and malignant conditions. The ICAM1 gene is located on chromosome 19 and contains two well-known single-nucleotide polymorphisms (SNP) of +241G/A (G241R) and +469A/G (K469E). In this study, the frequencies of the two polymorphisms were investigated in breast cancer patients and healthy individuals. For G241R, we selected 276 breast cancer patients and 235 healthy sex-matched controls, and for K469E, 264 patients and 200 healthy sex-matched controls were chosen. The results of this study show that the frequency of the GA genotype was significantly higher in breast cancer patients in comparison to the control group (P = 0.007). In addition, the frequency of the R allele was significantly higher in breast cancer patients compared to controls (P = 0.008). However, both the genotype and allele frequency of K469E did not differ significantly between patients and controls. A significant difference was observed in the frequency of genotype combination A/G (+241 G/A and +469 A/G, respectively) between patients and controls (6.2 vs. 2.2%; (*)P = 0.007). These findings indicate that individuals carrying the A allele of the ICAM1 gene as well as the A/G haplotype may have a higher risk of developing breast cancer.

Abstract
On the surface of the macrophage, annexin A2 tetramer (A2t) serves as a docking protein or recognition element for bacterial and viral pathogens. Plasma levels of free A2t have been reported to increase following infection, although the mechanistic significance of this observation is unclear. Although annexin A2 had generally been thought to play an anti-inflammatory role, soluble A2t stimulates MAP kinase activity in bone marrow stromal cells downstream of a recently cloned receptor. This raises the question of whether A2t activates human macrophages via MAP kinases and whether it might be capable of acting as an inflammatory mediator. To this end, human monocyte-derived macrophages were treated with soluble A2t and MAP kinase phosphorylation, p65 NF-kappaB activation, and inflammatory mRNA and protein levels were measured. It was found that A2t caused rapid phosphorylation of several MAP kinases, as well as translocation of p65 NF-kappaB to the nucleus. A2t stimulated the production of TNF-alpha, IL-1beta, and IL-6, as well as several members of the chemokine family within 24 h, which are capable of recruitment and/or activation of a broad range of leukocyte classes. Furthermore, A2t-activated macrophages demonstrated enhanced phagocytic ability for the ingestion of GFP-expressing Escherichia coli. These data are the first to suggest the participation of an annexin in microbial clearance, as well as the establishment of inflammation and the immune response, including the recruitment and activation of immune cells to the site of infection.

Abstract
Throughout the body, the distribution and differentiation of T-cell subsets varies in a way that optimizes host responses. The role of activation-induced cell death (AICD) in altering the distribution of T-lymphocyte subsets at an immune or inflammatory sites has been unexplored. The objective of this study was to assess whether pleural macrophages modulate AICD of specific pleural T-lymphocyte subsets. We found that pleural T-lymphocytes spontaneously undergo apoptosis, which is associated to increased expression of both FAS and FAS ligand, to decreased expression of Bcl 2 and to caspase 8 and 3 activation. While pleural T lymphocytes were partly protected from apoptosis, autologous peripheral blood T lymphocytes increased their apoptosis when cultured with exudative pleural fluids. Pleural CD45RO(+) T cells, in comparison to pleural CD45RA(+) T cells, were more susceptible to apoptosis, but were preferentially protected by exudative pleural fluids. Pleural prostaglandin E 2 (PGE(2)) was implicated in protecting T-lymphocytes from apoptosis because exudative pleural T lymphocytes highly express PGE(2) receptors, and because exudative pleural fluid contained high concentrations of PGE(2). Activated pleural macrophages released PGE(2) and reduced the spontaneous apoptosis of pleural T lymphocytes and depletion of PGE(2) from pleural fluids decreased this protective effect. This study demonstrates that PGE(2), released in the pleural fluids following pleural macrophage activation, prolongs the survival of specific T-cell subsets, resulting in differentiation of the T-cell repertoire within the inflamed pleural space.

Abstract
The recurrence of pleural effusions is a common event in a variety of neoplastic diseases. The objective of this study was to identify the mechanisms promoting the homing and growth of cancer cells within the pleural space. A cancer cell line recovered from malignant pleural fluids (lung adenocarcinoma cell line) that constitutively expresses cyclooxygenase 2 (COX-2) and all types of prostaglandin receptors was studied. It was first demonstrated using a matrigel system, that malignant pleural fluids increase the invasiveness of adenocarcinoma cells more than congestive heart failure (CHF) pleural fluids. Moreover, exposure to exudative malignant, but not to CHF pleural fluids, increased the mRNA (measured by real-time polymerase chain reaction (PCR)) and protein expression of COX-2 (measured by Western blot), as well as the activation and nuclear translocation of nuclear factor kappaB (NFkappaB) in cancer cells. These events are all actively regulated by prostaglandin E2 (PGE2), since the addition of synthetic PGE2 to cancer cells and the depletion of PGE2 from malignant pleural fluids or the inhibition of COX-2 activity significantly increased and reduced these phenomena, respectively. Moreover, malignant pleural effusions and synthetic PGE2 increased the long-term proliferation of cancer cells and reverted the impairment in long-term proliferation due to talc exposure. This study demonstrates that PGE2 present in malignant effusions contributes to cancer expansion and may protect cancer cells by anti-proliferative effects induced by talc.

Abstract
Ectodomain shedding has emerged as an important regulatory step in the function of transmembrane proteins. Intercellular adhesion molecule-1 (ICAM-1), an adhesion receptor that mediates inflammatory and immune responses, undergoes shedding in the presence of inflammatory mediators and phorbol 12-myristate 13-acetate (PMA). The shedding of ICAM-1 in ICAM-1-transfected 293 cells upon PMA stimulation and in endothelial cells upon tumor necrosis factor-alpha stimulation was blocked by metalloproteinase inhibitors, whereas serine protease inhibitors were ineffective. p-Aminophenylmercuric acetate, a mercuric compound that is known to activate matrix metalloproteinases, up-regulated ICAM-1 shedding. TIMP-3 (but not TIMP-1 or -2) effectively blocked cleavage. This profile suggests the involvement of the ADAM family of proteases in the cleavage of ICAM-1. The introduction of enzymatically active tumor necrosis factor-alpha-converting enzyme (TACE) into ICAM-1-expressing cells up-regulated cleavage. Small interfering RNA directed against TACE blocked ICAM-1 cleavage. ICAM-1 transfected into TACE-/- fibroblasts did not show increased shedding over constitutive levels in the presence of PMA, whereas cleavage did occur in ICAM-1-transfected TACE+/+ cells. These results indicate that ICAM-1 shedding is mediated by TACE. Blocking the shedding of ICAM-1 altered the cell adhesive function, as ICAM-1-mediated cell adhesion was up-regulated in the presence of TACE small interfering RNA and TIMP-3, but not TIMP-1. However, cleavage was found to occur at multiple sites within the stalk domain of ICAM-1, and numerous point mutations within the region did not affect cleavage, indicating that TACE-mediated cleavage of ICAM-1 may not be sequence-specific.

Abstract
PURPOSE OF REVIEW Lymphocytic pleural effusions are characterised by divergent cellular responses depending on the etiology of disease. The pathogenic role of lymphocytes in pleural disease, however, remains unclear. This review provides a basic description of the functions of the different lymphocyte subsets within the pleural space and then summarises recent studies of lymphocyte biology in pleural disease. RECENT FINDINGS The mechanisms of lymphocyte trafficking into the pleural space have been clarified. Specific adhesion molecules (such as intercellular adhesion molecule-1 and vascular cell adhesion molecule-1) and chemokines (CXCL13, interleukin-8, and monocyte chemotactic protein-1) have been identified as important factors involved in the accumulation of lymphocytes during inflammatory pleuritis. Both cellular and soluble factors may contribute to impaired T-cell immunity in malignant pleural effusions. Studies of natural killer cell and gammadelta T-cell biology indicate that these lymphocyte subsets may also play a role in the pathogenesis of pleural disease. The dominant Th1 response characterised by tuberculous pleuritis may allow for rapid diagnosis of disease. Furthermore, strategies for improving cytotoxic T-cell and natural killer cell function show promise for treatment of malignant pleural disease. SUMMARY Recent work has provided insight into the pathogenesis of disease in lymphocytic pleural effusions. Further study of specific cellular responses may offer significant opportunities in the diagnosis and management of these disorders.

Abstract
PURPOSE The circulating soluble form of intercellular adhesion molecule-1 (sICAM-1) and vascular endothelial growth factor (VEGF) are elevated in women with breast cancer and associated with tumor progression and poor prognosis. This study examined the effects of anthracycline-based chemotherapy on plasma sICAM-1 and VEGF, as well as soluble P-selectin, von Willebrand factor, and interleukin-6 levels. EXPERIMENTAL DESIGN Twenty-six women diagnosed with stage I-IIIA breast cancer (mean age, 48.4 +/- 10.4 years; range, 34-79 years) were studied before (week 1) and at weeks 2 and 3 of cycles 1 and 4 of chemotherapy. RESULTS The initial effect of chemotherapy was to reduce sICAM-1 levels; compared with pretreatment, sICAM-1 levels were decreased at week 2 of both cycles (P values < 0.01). sICAM-1 levels were elevated, however, at the start of cycle 4 as compared with pretreatment (P < 0.01). Chemotherapy led to an increase in sICAM-1 levels in node-positive but not node-negative patients (P < 0.01). VEGF levels were decreased at week 2 of cycle 4 (P = 0.001) and remained so at week 3. Similar to sICAM-1, VEGF levels were elevated at the start of cycle 4 as compared with pretreatment (P < 0.006). Soluble P-selectin levels decreased during week 2 of cycle 4 (P = 0.026). Neither interleukin-6 or von Willebrand factor were significantly changed in response to chemotherapy. CONCLUSIONS The findings support prior studies suggesting that sICAM-1 levels derive from sources other than endothelial cells. In addition, whereas the more immediate effect of chemotherapy is to reduce sICAM-1 and VEGF, continued treatment may lead to significant elevations.

Abstract
Chemotherapy for breast cancer leads to increased fatigue, poor mood, and reduced quality of life. Few studies have examined possible changes in inflammation during chemotherapy as potential contributors to this phenomenon. This study examined the relationship among circulating levels of soluble intercellular adhesion molecule-1 (sICAM-1), vascular endothelial growth factor (VEGF) and interleukin-6 (IL-6) and fatigue, depressed mood, and quality of life before and during anthracycline-based chemotherapy. Twenty-nine women diagnosed with stage I-IIIA breast cancer (mean age 49.5 years, S.D.+/-11) were studied prior to cycle 1 of chemotherapy and 2.5 months later at the start of cycle 4 of chemotherapy. Chemotherapy led to a significant increase in sICAM-1 (P<0.05) and VEGF (P<0.01) levels, as well as increased ratings of fatigue (P<0.01), depressed mood (P<0.03), and poorer quality of life (P<0.01). Multiple regression analyses revealed that elevated VEGF (P<0.01) and sICAM-1 (P<0.02) were related to the increased fatigue and/or poorer quality of life as a result of chemotherapy. Pre-chemotherapy levels of VEGF and pre-chemotherapy ratings of quality of life predicted quality of life in response to chemotherapy (P<0.001). The findings contribute to the literature by showing that both pre-chemotherapy and chemotherapy-induced changes in inflammation are related to changes in fatigue and quality of life in response to chemotherapy.

Abstract
Intercellular adhesion molecule-1 (ICAM-1) is a target for drug delivery to endothelial cells (ECs), which internalize multivalent anti-ICAM nanocarriers (anti-ICAM/NCs) within 15 to 30 minutes. The concomitant ICAM-1 disappearance from the EC surface transiently inhibited subsequent binding and uptake of anti-ICAM/NCs. Within 1 hour, internalized ICAM-1 diverged from anti-ICAM/NCs into prelysosomal vesicles, resurfaced, and enabled uptake of a subsequent anti-ICAM/NC dose. Thus, internalized ICAM-1 was able to recycle back to the plasma membrane. In vivo pulmonary targeting of a second anti-ICAM/NC dose injected 15 minutes after the first dose was decreased by 50% but recovered between 30 minutes and 2.5 hours, comparable to cultured ECs. Anti-ICAM/NCs affected neither EC viability nor fluid-phase endocytosis and traffic to lysosomes. However, lysosomal trafficking of the second dose of anti-ICAM/NCs was decelerated at least 2-fold versus the first dose; hence the major fraction of anti-ICAM/NCs resided in prelysosomal vesicles for at least 5 hours without degradation. Two successive doses of anti-ICAM/NC/catalase protected ECs against H2O2 for at least 8 hours versus 2 hours afforded by a single dose, suggesting that recurrent targeting to ICAM-1 affords longer effects. ICAM-1 recycling and inhibited lysosomal traffic/degradation of subsequent doses may help to prolong activity of therapeutic agents delivered into ECs by anti-ICAM/NCs.

Abstract
ICAM-1, a membrane-bound receptor, is released as soluble ICAM-1 in inflammatory diseases. To delineate mechanisms regulating ICAM-1 cleavage, studies were performed in endothelial cells (EC), human embryonic kidney (HEK)-293 cells transfected with wild-type (WT) ICAM-1, and ICAM-1 containing single tyrosine-to-alanine substitutions (Y474A, Y476A, and Y485A) in the cytoplasmic region. Tyrosine residues at 474 and 485 become phosphorylated upon ICAM-1 ligation and associate with signaling modules. Cleavage was assessed by using an antibody against the cytoplasmic tail of ICAM-1, which recognizes intact ICAM-1 and the 7-kDa membrane-bound fragment remaining after cleavage. Cleavage in HEK-293 WT cells was accelerated by phorbol ester PMA, whereas in EC it was induced by tumor necrosis factor-alpha. In both cell types, a 7-kDa ICAM-1 remnant was detected. Tyrosine phosphatase inhibitors dephostatin and sodium orthovanadate augmented cleavage. PD-98059 (MEK kinase inhibitor), geldanamycin and PP2 (Src kinase inhibitors), and wortmannin (phosphatidylinositol 3-kinase inhibitor) dose-dependently inhibited cleavage in both cell types. SB-203580 (p38 inhibitor) was more effective in EC, and D609 (PLC inhibitor) mostly affected cleavage in HEK-293 cells. Cleavage was drastically decreased in Y474A and Y485A, whereas it was marginally reduced in Y476A. Surprisingly, phosphorylation was not detectable on the 7-kDa fragment of ICAM-1. These results implicate distinct pathways in the cleavage process and suggest a preferred signal transmission route for ICAM-1 shedding in the two cell systems tested. Tyrosine residues Y474 and Y485 within the cytoplasmic sequence of ICAM-1 regulate the cleavage process.

Abstract
Nanotechnologies promise new means for drug delivery. ICAM-1 is a good target for vascular immunotargeting of nanoparticles to the perturbed endothelium, although endothelial cells do not internalize monomeric anti-ICAM-1 antibodies. However, coupling ICAM-1 antibodies to nanoparticles creates multivalent ligands that enter cells via an amiloride-sensitive endocytic pathway that does not require clathrin or caveolin. Fluorescence microscopy revealed that internalized anti-ICAM nanoparticles are retained in a stable form in early endosomes for an unusually long time (1-2 h) and subsequently were degraded following slow transport to lysosomes. Inhibition of lysosome acidification by chloroquine delayed degradation without affecting anti-ICAM trafficking. Also, the microtubule disrupting agent nocodazole delayed degradation by inhibiting anti-ICAM nanoparticle trafficking to lysosomes. Addition of catalase to create anti-ICAM nanoparticles with antioxidant activity did not affect the mechanisms of nanoparticle uptake or trafficking. Intracellular anti-ICAM/catalase nanoparticles were active, because endothelial cells were resistant to H2O2-induced oxidative injury for 1-2 h after nanoparticle uptake. Chloroquine and nocodazole increased the duration of antioxidant protection by decreasing the extent of anti-ICAM/catalase degradation. Therefore, the unique trafficking pathway followed by internalized anti-ICAM nanoparticles seems well suited for targeted delivery of therapeutic enzymes to endothelial cells and may provide a basis for treatment of acute vascular oxidative stress.
