Abstract
Epithelial intercellular adhesion molecule (ICAM)-1 is apically polarized, interacts with, and guides leukocytes across epithelial barriers. Polarized hepatic epithelia organize their apical membrane domain into bile canaliculi and ducts, which are not accessible to circulating immune cells but that nevertheless confine most of ICAM-1. Here, by analyzing ICAM-1_KO human hepatic cells, liver organoids from ICAM-1_KO mice and rescue-of-function experiments, we show that ICAM-1 regulates epithelial apicobasal polarity in a leukocyte adhesion-independent manner. ICAM-1 signals to an actomyosin network at the base of canalicular microvilli, thereby controlling the dynamics and size of bile canalicular-like structures. We identified the scaffolding protein EBP50/NHERF1/SLC9A3R1, which connects membrane proteins with the underlying actin cytoskeleton, in the proximity interactome of ICAM-1. EBP50 and ICAM-1 form nano-scale domains that overlap in microvilli, from which ICAM-1 regulates EBP50 nano-organization. Indeed, EBP50 expression is required for ICAM-1-mediated control of BC morphogenesis and actomyosin. Our findings indicate that ICAM-1 regulates the dynamics of epithelial apical membrane domains beyond its role as a heterotypic cell-cell adhesion molecule and reveal potential therapeutic strategies for preserving epithelial architecture during inflammatory stress.

Abstract
The dysregulated expression of immune checkpoint molecules enables cancer cells to evade immune destruction. While blockade of inhibitory immune checkpoints like PD-L1 forms the basis of current cancer immunotherapies, a deficiency in costimulatory signals can render these therapies futile. CD58, a costimulatory ligand, plays a crucial role in antitumor immune responses, but the mechanisms controlling its expression remain unclear. Using two systematic approaches, we reveal that CMTM6 positively regulates CD58 expression. Notably, CMTM6 interacts with both CD58 and PD-L1, maintaining the expression of these two immune checkpoint ligands with opposing functions. Functionally, the presence of CMTM6 and CD58 on tumor cells significantly affects T cell-tumor interactions and response to PD-L1-PD-1 blockade. Collectively, these findings provide fundamental insights into CD58 regulation, uncover a shared regulator of stimulatory and inhibitory immune checkpoints, and highlight the importance of tumor-intrinsic CMTM6 and CD58 expression in antitumor immune responses.

Detection of Aberrant CD58 Expression in a Wide Spectrum of Lymphoma Subtypes: Implications for Treatment Resistance. Mod Pathol 2023; 36:100256.

Abstract
CD58 or lymphocyte function-associated antigen-3, is a ligand for CD2 receptors on T and NK cells and is required for their activation and target cell killing. We recently showed a trend toward higher frequency of CD58 aberrations in patients with diffuse large B-cell lymphoma (DLBCL) who progressed on chimeric antigen receptor-T-cell treatment compared with those who responded. Given that CD58 status may be an important measure of T-cell-mediated therapy failure, we developed a CD58 immunohistochemical assay and evaluated CD58 status in 748 lymphomas. Our results show that CD58 protein expression is downregulated in a significant proportion of all subtypes of B-, T-, and NK-cell lymphomas. CD58 loss is significantly related to poor prognostic indicators in DLBCL and to ALK and DUSP22 rearrangements in anaplastic large-cell lymphoma. However, it is not associated with overall or progression-free survival in any of the lymphoma subtypes. As eligibility for chimeric antigen receptor-T-cell therapy is being extended to a broader spectrum of lymphomas, mechanisms of resistance, such as target downregulation and CD58 loss, may limit therapeutic success. CD58 status is therefore an important biomarker in lymphoma patients who may benefit from next-generation T-cell-mediated therapies or other novel approaches that mitigate immune escape.

Abstract
NKG2C is an activating NK cell receptor encoded by a gene having an unexpressed deletion variant. Cytomegalovirus (CMV) infection expands a population of NKG2C+ NK cells with adaptive-like properties. Previous reports found that carriage of the deleted NKG2C- variant was more frequent in people living with HIV (PLWH) than in HIV- controls unexposed to HIV. The frequency of NKG2C+ NK cells positively correlated with HIV viral load (VL) in some studies and negatively correlated with VL in others. Here, we investigated the link between NKG2C genotype and HIV susceptibility and VL set point in PLWH. NKG2C genotyping was performed on 434 PLWH and 157 HIV-exposed seronegative (HESN) subjects. Comparison of the distributions of the three possible NKG2C genotypes in these populations revealed that the frequencies of NKG2C+/+ and NKG2C+/- carriers did not differ significantly between PLWH and HESN subjects, while that of NKG2C-/- carriers was higher in PLWH than in HESN subjects, in which none were found (P = 0.03, χ2 test). We were unable to replicate that carriage of at least 1 NKG2C- allele was more frequent in PLWH. Information on the pretreatment VL set point was available for 160 NKG2C+/+, 83 NKG2C+/-, and 6 NKG2C-/- PLWH. HIV VL set points were similar between NKG2C genotypes. The frequency of NKG2C+ CD3- CD14- CD19- CD56dim NK cells and the mean fluorescence intensity (MFI) of NKG2C expression on NK cells were higher on cells from CMV+ PLWH who carried 2, versus 1, NKG2C+ alleles. We observed no correlations between VL set point and either the frequency or the MFI of NKG2C expression. IMPORTANCE We compared NKG2C allele and genotype distributions in subjects who remained HIV uninfected despite multiple HIV exposures (HESN subjects) with those in the group PLWH. This allowed us to determine whether NKG2C genotype influenced susceptibility to HIV infection. The absence of the NKG2C-/- genotype among HESN subjects but not PLWH suggested that carriage of this genotype was associated with HIV susceptibility. We calculated the VL set point in a subset of 252 NKG2C-genotyped PLWH. We observed no between-group differences in the VL set point in carriers of the three possible NKG2C genotypes. No significant correlations were seen between the frequency or MFI of NKG2C expression on NK cells and VL set point in cytomegalovirus-coinfected PLWH. These findings suggested that adaptive NK cells played no role in establishing the in VL set point, a parameter that is a predictor of the rate of treatment-naive HIV disease progression.

Abstract
Intercellular adhesion molecule-1 (ICAM-1) is a cell-surface receptor contributing to lymphocyte homing, adhesion and activation. The prognostic significance of the protein is unknown in diffuse large B-cell lymphoma (DLBCL) in post-rituximab era. We detected expression of ICAM-1 immunohistochemically in 102 DLBCL tissue samples. Overexpression of ICAM-1 was found in 28 (27.5%) cases. In patients with low ICAM-1 expression levels, the addition of rituximab to CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) chemotherapy resulted in an improved overall response rate, progression-free survival (PFS) and overall survival (OS) (P=0.019, 0.01, 0.02). In pre-clinical models, we found that chronic exposure of cell lines to rituximab led to downregulation of ICAM-1 and acquirement of a rituximab resistant phenotype. In vitro exposure of rituximab resulted in rapid aggregation of B-cells regardless of the ICAM-1 expression levels. MTT assay showed knockdown of ICAM-1 could cause rituximab resistance. Neutralization of ICAM-1 did not affect rituximab activity in vitro and in vivo. Our data illustrated that in post-rituximab era, R-CHOP significantly improved the ORR, PFS and OS in ICAM-1 negative subset patients. Downregulation of ICAM-1 may contribute to rituximab resistance, and that rituximab, by promoting cell-cell aggregation, may sensitize cells to the cytotoxic effects of chemotherapy agents.

Abstract
Acute myocardial infarction (MI) evokes a systemic inflammatory response and locally the degradation of the necrotic tissue, followed by scar formation. The mechanisms for containment of the infarct zone are not studied well. The study aimed to examine the response of healthy cardiomyocytes to serum of patients with myocardial infarction. Human iPSC-cardiomyocytes (iPSC-CM) generated from two healthy donors were incubated with serum of patients with MI with and without ventricular fibrillation (VF) or of healthy controls. Different cell adhesion molecules were studied by flow cytometry and immunostaining. Cellular electrophysiology was studied by patch clamp. The cell adhesion molecules CD54/ICAM-1, CD58/LFA-3 and CD321/JAM-A were expressed on iPSC-CM within the plasma membrane. Incubation with serum of MI patients reduced the levels of expression of CD54/ICAM-1 and CD321/JAM-A by 15–20%. VF serum was less effective than serum of MI patients without VF. MI serum or VF serum did not affect resting potential, action potential duration or maximum depolarization velocity. Myocardial infarction serum exerts anti-inflammatory effects on healthy cardiomyocytes without affecting their electrical activity, thus helping to contain the infarct zone and to protect healthy tissue. Ventricular fibrillation during MI drives healthy cardiomyocytes towards a pro-inflammatory phenotype.

Abstract
The identification of novel biomarkers for hepatocellular carcinoma (HCC) is of great importance in improving the outcome of patients with HCC. The present study aimed to determine the prognostic significance of the soluble intercellular adhesion molecule (sICAM)-1 in patients with HCC. The present study prospectively collected clinicopathological data from 36 patients with HCC who had undergone successful hepatectomy. An analysis using a receiver operating characteristic (ROC) curve was performed to determine the cut-off value for predicting prognosis. Overall survival (OS), recurrence-free survival (RFS) and potential prognostic factors were analyzed. The ROC curve analysis revealed a sICAM-1 cut-off value of 440 ng/ml. HCC patients with sICAM-1 ≥440 ng/ml exhibited a poorer OS and RFS than those with sICAM-1 <440 ng/ml (P=0.002). sICAM-1 ≥440 ng/ml (hazard ratio=3.623; 95% confidence interval: 1.145-11.458; P=0.028) and Child B (hazard ratio=1.514; 95% confidence interval: 1.066-2.150; P=0.021) were independent prognostic factors for OS, and sICAM-1 ≥440 ng/ml was an independent prognostic factor for RFS (hazard ratio=3.625; 95% confidence interval: 1.233-10.659; P=0.019). Serum sICAM-1 may be a promising predictor for the overall and recurrence-free survival of patients with HCC.

Purpose/Aim: Although several prognostic factors for extrahepatic cholangiocarcinoma (EHC) have been reported, preoperative prognostic factors have yet to be established. We investigated the serum concentration of angiogenic, inflammatory, and nutritional parameters. MATERIALS AND METHODS Twenty-five patients with EHC were enrolled before starting treatment. Preoperative prognostic factors were identified using multivariate analyses. RESULTS The serum soluble intercellular adhesion molecule-1 (sICAM-1) levels were significantly higher in the patients with EHC (436.0 ± 43.2 ng/ml) than in the healthy volunteers (228.6 ± 22.0 ng/ml) (p <.001). In addition, the serum IL-6 levels were significantly higher in the patients (18.0 ± 5.6 pg/ml) than in the healthy volunteers (5.7 ± 0.8 pg/ml) (p <.05). The serum IL-6 and sICAM-1 showed a strong correlation (r = 0.559) in the patients with EHC (p <.01). The serum IL-6 (area under the curve = 0.764, p =.030, cut-off level = 11.6) and sICAM-1 (area under the curve = 0.818, p =.007, cutoff level = 322.6) were revealed to be useful as prognostic factors by the receiver operating characteristic curves. The high IL-6 group and the high sICAM-1 group showed poorer DSS than those of the respective low groups. In the multivariate analysis, IL-6 (hazard ratio: 1.050, 95% confidence interval: 1.002-1.100, p =.043) and sICAM-1 (hazard ratio: 1.009, 95% confidence interval: 1.002-1.015, p =.009) were independent prognostic factors for DSS. CONCLUSIONS IL-6 and sICAM-1 were independent preoperative prognostic factors in EHC patients, causing continuous inflammation and malnutrition in collaboration with other pro-angiogenic factors.

Abstract
Viral infections continuously challenge and shape our immune system. Due to their fine antigen recognition ability, adaptive lymphocytes protect against pathogen reencounter by generating specific immunological memory. Innate cells such as macrophages also adapt to pathogen challenge and mount resistance to reinfection, a phenomenon termed trained immunity. As part of the innate immunity, natural killer (NK) cells can display rapid effector functions and play a crucial role in the control of viral infections, especially by the β-herpesvirus cytomegalovirus (CMV). CMV activates the NK-cell pool by inducing proinflammatory signals, which prime NK cells, paralleling macrophage training. In addition, CMV dramatically shapes the NK-cell repertoire due to its ability to trigger specific NK cell-activating receptors, and enables the expansion and persistence of a specific NK-cell subset displaying adaptive and memory features. In this chapter, we will discuss how different signals during CMV infection contribute to NK-cell training and acquisition of classical memory properties and how these events can impact on reinfection and cross-resistance.

Abstract
Infection by human cytomegalovirus (HCMV) leads to NKG2C-driven expansion of adaptive natural killer (NK) cells, contributing to host defense. However, approximately 4% of all humans carry a homozygous deletion of the gene that encodes NKG2C (NKG2C−/−). Assessment of NK cell repertoires in 60 NKG2C−/− donors revealed a broad range of NK cell populations displaying characteristic footprints of adaptive NK cells, including a terminally differentiated phenotype, functional reprogramming, and epigenetic remodeling of the interferon (IFN)-γ promoter. We found that both NKG2C− and NKG2C+ adaptive NK cells expressed high levels of CD2, which synergistically enhanced ERK and S6RP phosphorylation following CD16 ligation. Notably, CD2 co-stimulation was critical for the ability of adaptive NK cells to respond to antibody-coated target cells. These results reveal an unexpected redundancy in the human NK cell response to HCMV and suggest that CD2 provides “signal 2” in antibody-driven adaptive NK cell responses. NKG2C−/− donors have normal T cell immunity to cytomegalovirus NKG2C−/− donors have normal frequencies of adaptive NK cells CD2 is critical for antibody-triggered responses by adaptive NK cells CD2 synergizes with NKG2C in classical adaptive NK cells

Abstract
CD48, a member of the signaling lymphocyte activation molecule family, participates in adhesion and activation of immune cells. Although constitutively expressed on most hematopoietic cells, CD48 is upregulated on subsets of activated cells. CD48 can have activating roles on T cells, antigen presenting cells and granulocytes, by binding to CD2 or bacterial FimH, and through cell intrinsic effects. Interactions between CD48 and its high affinity ligand CD244 are more complex, with both stimulatory and inhibitory outcomes. CD244:CD48 interactions regulate target cell lysis by NK cells and CTLs, which are important for viral clearance and regulation of effector/memory T cell generation and survival. Here we review roles of CD48 in infection, tolerance, autoimmunity, and allergy, as well as the tools used to investigate this receptor. We discuss stimulatory and regulatory roles for CD48, its potential as a therapeutic target in human disease, and current challenges to investigation of this immunoregulatory receptor.

Abstract
Nasal natural killer-T cell lymphoma (NNKTL) is associated with the Epstein-Barr virus and has distinct histologic features, such as angiocentric and polymorphous lymphoreticular infiltrates that contain too many cell types, including tumor and inflammatory cells. We have shown previously that intercellular adhesion molecule (ICAM)-1 is expressed in NNKTL cells, and that soluble ICAM-1 (sICAM-1) is significantly increased in patients' sera. However, the functional role of sICAM-1 remains unknown. In this study, we found that Epstein-Barr virus-positive NNKTL cell line SNK6 secreted sICAM-1 in a time-dependent manner. Moreover, exogenous sICAM-1 enhanced the growth of SNK6 cells in a dose-dependent manner. In comparison, neutralizing ICAM-1 and LFA-1 antibodies, as well as the LFA-1 blocker simvastatin, caused a dose-dependent reduction in the number of viable SNK6 cells. Double immunohistologic staining of NNKTL tissues confirmed that CD56 positive lymphoma cells coexpressed LFA-1. Moreover, serum sICAM-1 levels in NNKTL patients decreased after treatment, suggesting that the levels reflected disease progression. We conclude that NNKTL cells secrete sICAM-1 that acts as an autocrine factor for lymphoma progression, and suggest that simvastatin could be a potential candidate to treat NNKTL.

Abstract
The vascular endothelium is the main target of a limited number of infectious agents, Rickettsia, Ehrlichia ruminantium, and Orientia tsutsugamushi are among them. These arthropod-transmitted obligately-intracellular bacteria cause serious systemic diseases that are not infrequently lethal. In this review, we discuss the bacterial biology, vector biology, and clinical aspects of these conditions with particular emphasis on the interactions of these bacteria with the vascular endothelium and how it responds to intracellular infection. The study of these bacteria in relevant in vivo models is likely to offer new insights into the physiology of the endothelium that have not been revealed by other models.

Abstract
CD54/Intercellular Adhesion Molecule-1 (ICAM-1) is a cell adhesion molecule largely distributed among normal and neoplastic tissues. Through the binding to its ligand(s) CD54 plays a key role in cell to cell interactions leading to the immune response. Recently, CD54 expression has been investigated on hematopoietic cells: the antigen is predominantly expressed in the early stages of normal hematopoiesis and during the activation of blood cells. As regards to hematological malignancies, CD54 is strongly expressed on neoplastic cells from "stem cell derived" neoplasms. In AML, CD54 expression is related with other differentiation-linked molecules such as CD34 and HLA-DR and is significantly correlated with FAB morphological classification. In lymphoproliferative disorders, a high CD54 expression is associated with germinal centre lymphomas. This review summarizes our current understanding of CD54 with emphasis on recent advances and reference to unresolved issues such as its prognostic role in the clinical outcome of oncohematological diseases.

Abstract
Intercellular adhesion molecule-1 (ICAM-1) is implicated to play a role in cancer metastasis, and may serve as a diagnostic tool for tumor prognosis and progression as well as a target for therapeutic intervention. The aim of this study was to carry out a comprehensive survey of ICAM-1 immunoreactivity in normal, malignant and metastatic tissues. We assessed immunoreactivity of ICAM-1 in a total of 300 tissue cores from multiple tissue arrays of normal, malignant, and metastatic tissues by immunohistochemistry. We scored tissue samples for ICAM-1 immunoreactivity on a 0-3 scale, assessed the number of samples exhibiting infiltrating immune cells, and documented ICAM-1 immunoreactivity in some specific cell types. ICAM-1 expression in normal tissues was highest in spleen and absent in the cerebrum, peripheral nerves, pancreas, ovary, breast, uterus, cervix, prostate, lung, larynx, bone marrow, striated muscle, heart, mesothelium, esophagus, small intestine, colon and liver. In primary malignancies, lymphoid tissues received the highest average ICAM-1 score while connective tissue/skin had the lowest average ICAM-1 score. Of the metastatic tissues, those originating from the urinary tract had the highest average ICAM-1 score while those originating from glandular tissues had the lowest average ICAM-1 score. Metastases localized in lymphoid tissues had a higher average ICAM-1 score than those localized in non-lymphoid tissues. Since ICAM-1 is associated with a variety of cancer types and appears to play a role in cancer metastasis, our findings should serve as a helpful resource for investigations of ICAM-1 as a biomarker, as well as a target for therapeutic interventions.

Abstract
The ezrin, radixin, and moesin (ERM) proteins represent a family of adaptor proteins linking transmembrane proteins to the cytoskeleton. The seminiferous epithelium undergoes extensive changes in cellular composition, location, and shape, implicating roles of the membrane-cytoskeleton interaction. It remains unknown, however, whether the ERM proteins are expressed and play significant roles in the testis. In the present study, we examined the spatiotemporal expression of ERM proteins in the mouse testis by Western blotting and immunohistochemistry. Ezrin immunoreactivity was demonstrated in the cytoplasm of steps 15 and 16 spermatids from 5 weeks postpartum through adulthood, whereas radixin immunoreactivity was in the apical cytoplasm of Sertoli cells from 1 week through 2 weeks postpartum. No immunoreactivity for moesin was detected at any age. Immunoprecipitation demonstrated that ezrin was bound to the cytoskeletal component actin, whereas radixin was bound to both actin and tubulin. Of the transmembrane proteins known to interact with ERM proteins, only cystic fibrosis transmembrane conductance regulator, a chloride transporter, was bound to ezrin in elongated spermatids. These results suggest that ezrin is involved in spermiogenesis whereas radixin is involved in the maturation of Sertoli cells, through interaction with different sets of membrane proteins and cytoskeletal components.

Abstract
BACKGROUND Soluble intercellular adhesion molecule-1 (sICAM-1) represents a circulating form of ICAM-1 that is constitutively expressed or is inducible, which localizes to the cell surfaces of different cell lines and is related to the metastatic potential of cancer cells. The aim of the present study was to determine the relationships between the preoperative serum concentration of sICAM-1 and clinicopathological features, established tumor markers and prognosis, in colorectal cancer patients. METHODS One hundred and thirty-eight patients with histologically proven colorectal cancer and 40 normal volunteers were included in this trial. Preoperative serum was collected, and sICAM-1 levels were assayed using a commercially available enzyme-linked immunosorbent assay kit. RESULTS The mean sICAM-1 level in patients was significantly higher than that in controls, and increased with disease progression. The prognosis of patients with an elevated sICAM-1 level was significantly worse than that of patients with a normal sICAM-1 level. In a Cox multivariate analysis, the strongest prognostic factor in all patients was distant metastasis followed by sICAM-1 level, while in patients with stage II classification, the strongest prognostic factor was serum level of sICAM-1. The prognosis of stage II patients positive for sICAM-1 was comparable to that of stage III patients. CONCLUSIONS Preoperative sICAM-1 level is an independent prognostic marker for stage II colorectal cancer. Measuring serum sICAM-1 may provide valuable information, especially for stage II patients, when selecting appropriate candidates for adjuvant chemotherapy.

Abstract
OBJECTIVE To estimate the serum levels of soluble intercellular adhesion molecule-1 (s-ICAM-1) in children newly diagnosed with lymphoma and to correlate levels of s-ICAM-1 in lymphoma patients with clinical stage, pathological types, clinical and laboratory data and patient outcome. SUBJECTS AND METHODS Thirty-five children with newly-diagnosed malignant lymphoma (Non-Hodgkin's lymphoma, NHL: 23), Hodgkin's disease (HD: 12), and 8 apparently healthy subjects of matched age and sex taken as a control group were studied. For the patients and control group, the following tests were performed: complete blood count, and the following biochemical investigations: liver function tests, lactate dehydrogenase (LDH), and soluble ICAM-1 estimation using ELISA. In addition, for patients, pathological examination of lymph node biopsy for pathological grading, bone marrow aspiration and biopsy were done. Patients were observed for over 12 months or until death. RESULTS Serum ICAM-1 increased more in HD and NHL than in the control group (p < 0.000); also s-ICAM-1 increased in advanced stages and high-grade NHL (p < 0.008, 0.04, respectively). LDH levels were higher in patients compared to controls (p < 0.000). There was a positive correlation between high levels of s-ICAM-1 and increased levels of LDH in HD (r = 0.72, p < 0.008) and a positive correlation between high levels of s-ICAM-1 and increased ALT in NHL patients. A positive correlation between s-ICAM-1 levels and the presence of B symptoms in HD and NHL, and a positive correlation between elevated s-ICAM-1 levels and worse outcome in HD and NHL were detected. CONCLUSIONS The data indicate that in children with malignant lymphoma, high serum levels of ICAM-1 correlated with tumor aggressiveness, and quantification of s-ICAM-1 levels may identify a subgroup of children with worse prognosis. Therefore, detection of s-ICAM-1 levels in children with malignant lymphoma might represent an additional disease-associated marker for use in the clinical management of the patients.

Abstract
Endothelial cells lining the blood vessels form a barrier between circulating immune cells and parenchymal tissue. While the molecular mechanisms involved in antigen-independent recruitment of leukocytes into infected tissue have been extensively studied, the mechanisms involving antigen-specific recruitment of T cells into tissue have remained largely elusive. Here I shall review the experimental evidence that endothelial cells function as antigen-presenting cells and in this function contribute first to regulation of immune responses and second, to antigen-specific recruitment of T cells.

Abstract
The CD2 family of receptors is evolutionarily conserved and widely expressed on cells within the hematopoietic compartment. In recent years several new members have been identified with important roles in the immune system. CD2 family members regulate natural killer (NK) cell lytic activity and inflammatory cytokine production when engaged by ligands on tumor cells. Furthermore, a subfamily of CD2 receptors, the CD 150-like molecules, has been implicated in the pathogenesis of X-linked lymphoproliferative disease (XLP). Many of these receptors have now been shown to bind homophilically or heterophilically to other molecules within the family. With these discoveries a novel mechanism for lymphocyte regulation has emerged: CD2 family members on NK cells engage ligands on neighboring NK cells, leading to NK cell stimulation. Moreover, heterotypic stimulatory interactions between NK cells and other leukocytes also occur. In this manner, CD2 family members may provide interlymphocyte communication that maintains organization within the hematopoietic compartment and amplifies immune responses. This review discusses these multiple roles for CD2 family members, focusing specifically on the regulation of NK cells.

Abstract
Novel panning and screening methodology was devised to isolate high affinity human recombinant scFv antibody fragments with functionally associated properties in B lymphoma cells. The approach was used to generate a panel of apoptosis-inducing antibodies specific for antigens differentially expressed in B lymphoma vs. T leukaemia cells. The selections resulted in an antibody pool with near perfect selectivity (>99%) for the B lymphoma target cells. Randomly picked clones (72) revealed 7 unique antibody genotypes. Six of these rapidly induced apoptosis in target cells. Following the conversion to full IgGs, the antibodies were shown to be specific for HLA-DR/DP, the B-cell receptor mu chain and for CD54/ICAM-1. The latter receptor was not previously associated with apoptotic properties in B-cell lymphomas. Anti-ICAM-1 IgG induced apoptosis in a broad range of B lymphoma cell lines and were shown by immunohistochemistry to bind strongly to B lymphoma tissue obtained from 5 different B lymphoma patients. The recombinant IgG antibodies had affinities in the subnanomolar (0.3 nM) to nanomolar (3 nM) range. The described technology is generally applicable for the rapid isolation of high affinity human antibodies with specificity for differentially expressed cell surface receptors with intrinsic negative or positive signalling properties from naïve phage libraries.

Abstract
We have shown that administration of a novel anti-CD54 monoclonal antibody (UV3) results in long-term survival of SCID mice bearing human myeloma xenografts. Previous studies have demonstrated a link between the expression of CD54 and the progression of uveal melanoma. Our study assessed the expression of CD54 on 7 human uveal melanoma cell lines and 3 cell lines established from uveal melanoma metastases. In vivo studies examined the efficacy of systemic and local administration of UV3 antibody on the progression of uveal melanoma cells transplanted either heterotopically or orthotopically into SCID mice. Five of the 7 primary uveal melanoma cell lines and all 3 of the metastases cell lines expressed CD54. Intraperitoneal injection of either IgG or F(ab')2 fragments of UV3 significantly inhibited the growth of subcutaneous and intraocular melanomas. Subconjunctival injection of either IgG or F(ab')2 fragments of UV3 produced a significant reduction in the growth of intraocular melanomas, even if the antibody was administered after the appearance of intraocular tumors. The results indicate that both primary and metastatic human uveal melanoma cells express CD54. The marked inhibition of intraocular and subcutaneous uveal melanoma progression suggests that UV3 antibody is a promising therapeutic agent for further evaluation in patients with uveal melanoma. This is especially noteworthy, as no existing therapeutic modality prevents metastasis of uveal melanoma or prolongs the survival of patients with uveal melanoma.

Abstract
Infected CD4+ T cells are the primary sites of human immunodeficiency virus type 1 (HIV-1) replication in vivo. However, signals from professional antigen-presenting cells (APCs), such as dendritic cells and macrophages, greatly enhance HIV-1 replication in T cells. Here, we report that in cocultures, vascular endothelial cells (ECs), which in humans can also serve as APCs, can enhance HIV-1 production of both CCR5- and CXCR4-utilizing strains approximately 50,000-fold. The observed HIV-1 replication enhancement conferred by ECs occurred only in memory CD4+ T cells, required expression of major histocompatibility complex class II (MHC-II) molecules by the ECs, and could not be conferred by fixed ECs, all of which are consistent with a requirement for EC-mediated T-cell activation via T-cell receptor (TCR) signaling. Deletion of nef (Nef-) decreased HIV-1 production by approximately 100-fold in T cells cocultured with ECs but had no effect on virus production in T cells cocultured with professional APCs or fibroblasts induced to express MHC-II. Human ECs do not express B7 costimulators, but Nef- replication in CD4(+)-T-cell and EC cocultures could not be rescued by anti-CD28 antibody. ECs act in trans to enhance wild-type but not Nef- replication and facilitate enhanced wild-type replication in naive T cells when added to T-cell or B-lymphoblastoid cell cocultures, suggesting that ECs also provide a TCR-independent signal to infected T cells. Consistent with these in vitro observations, wild-type HIV-1 replicated 30- to 50-fold more than Nef- in human T cells infiltrating allogeneic human skin grafts on human huPBL-SCID/bg mice, an in vivo model of T-cell activation by ECs. Our studies suggest that ECs, which line the entire cardiovascular system and are, per force, in frequent contact with memory CD4+ T cells, provide signals to HIV-1-infected CD4+ T cells to greatly enhance HIV-1 production in a Nef-dependent manner, a mechanism that could contribute to the development of AIDS.

Abstract
A panel of anti-human CD2 monoclonal antibodies (mAb) and soluble human CD58 (LFA-3) were tested for binding to human peripheral blood mononuclear cells (PBMCs), recombinant human CD2 and mononuclear cells from Cynomolgus, Rhesus and African green monkey, Stump-tail, Pig-tail and Assamese macaque, Chimpanzee and Baboon. This analysis revealed that whilst some antibodies recognized all species, there were differential binding profiles with others. Three antibodies, MEDI-507, 6F10.3 and 4B2, recognized CD2 from human and Chimpanzee but not that from the other primates. We have cloned eight of the previously unknown primate CD2 molecules and report here their sequences for the first time. This analysis revealed that 12 amino acids formed a common set of residues in the extra cellular domain of human and Chimpanzee CD2. Using a "knock-in" mutagenesis approach starting with Baboon CD2, which does not bind MEDI-507, 6F10.3 and 4B2, we have identified three residues in the adhesion domain of human CD2 which are critical for its binding to these mAbs. These residues, N18, K55 and T59 define a region located outside of the previously described binding regions on CD2. Affinity measurements of the mutants revealed a variety of degrees of binding restoration for MEDI-507, 6F10.3 and 4B2, indicating that there are fine differences within a given epitope. Furthermore, the analysis of the competition of several of the anti-human CD2 antibodies with each other and CD58 demonstrated the existence of a continuum of overlapping epitopes on human CD2, which is in contrast to the commonly held belief that epitopes on human CD2 are clearly segregated.

Abstract
Human vascular endothelial cells (EC) basally display class I and II MHC-peptide complexes on their surface and come in regular contact with circulating T cells. We propose that EC present microbial antigens to memory T cells as a mechanism of immune surveillance. Activated T cells, in turn, provide both soluble and contact-dependent signals to modulate normal EC functions, including formation and remodeling of blood vessels, regulation of blood flow, regulation of blood fluidity, maintenance of permselectivity, recruitment of inflammatory leukocytes, and antigen presentation leading to activation of T cells. T cell interactions with vascular EC are thus bidirectional and link the immune and circulatory systems.

Abstract
The role of CD2 signaling in cytotoxic T lymphocyte (CTL) development was examined by stimulating mouse T cells with anti-CD3 monoclonal antibody (mAb) in the absence or presence of anti-CD2 mAb or anti-CD48 mAb or both. Induction of nonspecific CTL and interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) synthesis were impaired in the absence of CD2-CD48 interactions. Anti-CD2 mAb also inhibited activation-induced expression of the high-affinity IL-2 receptor (IL-2R). In contrast, IFN-gamma receptor (IFNGR) expression was increased in the presence of anti-CD2 mAb. Reduced cytotoxicity by CTL induced in the absence of CD2-CD48 interactions was associated with a diminished ability of CTL to conjugate with target cells and reduced expression of granzyme B and perforin. Anti-CD2 mAb did not affect expression of Fas ligand and tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) by anti-CD3-activated T cells. Cytotoxic effector function and granzyme B and perforin expression were rescued when exogenous IL-2 and IFN-gamma were added in combination with anti-CD2 mAb to anti-CD3-activated T cells at initiation of culture. We conclude that CD2-CD48 interactions during T cell activation are critical for the synthesis of sufficient IL-2 and IFN-gamma to drive CD8(+) T cells to differentiate into functional cytotoxic effector cells.

Abstract
Effects of several cytokines on kinetics of Intercellular Adhesion Molecule-1 (ICAM-1) and Vascular Cell Adhesion Molecule-1 (VCAM-1) expression were studied on a bronchial epithelial cell line (BEAS-2B). VCAM-I was neither constitutively expressed on BEAS-2B cells nor induced by Interferon-gamma (IFN-gamma). Tumor Necrosis Factor-alpha (TNF-alpha), Interleukin-1beta (IL-1beta), IFN-alpha, IL-4, IL-6, IL-8 or Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF). ICAM-1 was constitutively expressed on BEAS-2B cells. IFN-gamma and TNF-alpha upregulated ICAM-1 expression on these cells. The functional importance of IFN-gamma plus TNF-a upregulation of ICAM-1 expression on BEAS-2B cells was demonstrated by neutrophil-BEAS-2B cell adhesion assays. Cytokines are rapidly released and cleared in animals. Therefore, transient cytokine(s) exposure might occur on the bronchial mucosa. Brief incubation of BEAS-2B cells with IFN-gamma plus TNF-alpha led initial upregulation of ICAM-1 expression followed by a protracted downregulation. Our findings stress the importance of studying the mechanism(s) controlling the persistent increased expression of ICAM-1 after brief cytokine(s) exposure.

Abstract
The adhesion molecule lymphocyte function-associated antigen 3 (LFA-3) (CD58) is an important regulator of immune cell function which occurs as both surface-associated and 'soluble' forms. This study has investigated the inter-relationship and the effects of cytokines on the expression of LFA-3 isoforms. The surface antigen was found to be relatively unaffected by cytokines, but the release of soluble LFA-3 (sLFA-3) was highly responsive to interleukin 1beta (IL-1beta), interferon gamma (IFN-gamma) and tumour necrosis factor alpha (TNF-alpha). This modulation was cell-specific, particularly with regard to IFN-gamma, which up-regulated sLFA-3 release by A431 cells but down-regulated the release of the soluble form from HEp2 and HepG2 cells. We further demonstrated that LFA-3 is also present in a cytoplasmic 'pool' in each of the cells and, moreover, that cleavage of LFA-3 from the cell surface by phospholipase C resulted in an increase in the levels of the intracellular LFA-3 and replacement of the membrane-associated antigen. These observations suggest that the expression of the surface, soluble and intracellular forms of LFA-3 may be linked by regulatory mechanisms which are likely to exert an important influence on inflammatory interactions.

Abstract
We investigated whether a relationship existed between soluble adhesion molecules and vascular damage from vibration-induced white finger. Thirty-five men exposed to vibration and 40 healthy control subjects were examined. Concentrations of soluble E-selectin intercellular adhesion molecules, and vascular cell adhesion molecules in serum were measured with sandwich enzyme-linked adhesion immunosorbent assay. Neither E-selectin nor intercellular adhesion molecule levels are elevated in men exposed to vibration with white finger compared to levels in men exposed to vibration without white finger and control subjects. The serum level of soluble vascular cell adhesion molecules is significantly increased in patients with vibration-induced white finger.

Abstract
Nitric oxide (NO) production is increased in several inflammatory disorders. We have previously demonstrated higher levels of NO production among patients with rheumatoid arthritis and systemic lupus erythematosus. In this study we measured serum levels of nitrite and citrulline using calorimetric methods as surrogate markers of NO production among patients with inflammatory myositis (IM). Twenty patients with IM and 19 age- and sex-matched controls were studied. Serum nitrite levels were significantly higher among patients than among controls (986.6 +/- 880 and 204.3 +/- 113.9 nmol/ml, respectively; P = 0.001). Serum citrulline levels, too, were significantly higher among patients than among controls (3755.7 +/- 1905.5 and 189 +/- 177.2 nmol/ml, respectively; P < 0.0001). There was a positive correlation between steroid dosage and serum citrulline levels (r = 0.51, P = 0.036) and a negative correlation between steroid dosage and disease duration (r = -0.54, P = 0.025). It was concluded that NO production is increased in patients with IM and those with more active disease, as indicated by higher steroid dosage, have higher serum citrulline levels.

Abstract
To date, no soluble markers can discriminate benign from malignant breast lesions; therefore, to assess the diagnostic potential of circulating intercellular adhesion molecule-1 (sICAM-1), serum concentrations of sICAM-1 were quantitated in 230 consecutive patients that underwent surgery for breast neoplasias, utilizing an enzyme-linked immunosorbent assay. Histological diagnosis revealed that 177 patients had breast cancer and 53 had a benign breast disease. In the cancer patient group, 90 subjects had pT1 tumors without (pT1N0M0, n = 46) or with (pT1N1M0, n = 41; pT1N2M0, n = 3) regional lymph node metastases. Mean levels of serum sICAM-1 of patients with pT1 breast cancer, without or with regional lymph node involvement, were significantly (P < 0.05) higher than those of patients with benign breast lesions and of 49 age-matched control subjects. Elevated levels of serum sICAM-1 were detected in 27/90 (30%) pT1 breast tumors and in 1/53 (2%) benign breast lesions; thus, among subjects with high levels of sICAM-1, 96% had breast cancer. No significant correlation was found between levels of serum sICAM-1 and breast cancer progression. These observations, altogether, suggest that in the presence of a suspicious breast neoplasm the quantitative analysis of serum sICAM-1 can orient clinical diagnosis towards malignancy.

Abstract
Detecting and/or monitoring changes in circulating tumor markers might assist in evaluating cancer risk, diagnosis, prognosis, or response to treatment. Several categories of circulating tumor markers have been investigated in breast cancer. These categories include classical tumor-associated antigens, such as CEA and CA 15-3, markers of tumor biology, including markers of angiogenesis, adhesion, and invasion, and antibody response to tumor-associated antigens such as HER2/neu and p53. We used a recently proposed Tumor Marker Utility Grading System to evaluate the use of several circulating tumor markers for different clinical utilities in breast cancer. While there are no tumor markers with established clinical utilities for most uses, tumor-associated antigens can be used for monitoring patients with metastatic disease. In addition, markers of tumor biology such as the circulating extracellular domain of HER2/neu might be useful in determining not only prognosis, but also response to specific treatments. However, further investigations are required to further assess the utility of individual tumor markers for specific clinical uses.

Abstract
The sera from patients with nasopharyngeal carcinoma (n = 30), oral carcinoma (n = 22) and laryngeal carcinoma (n = 22) was extracted before treatment. The concentration of circulating intercellular adhesion molecule 1 (ICAM-1), E-selectin and vascular cell adhesion molecule 1 (VCAM-1) was measured by enzyme-linked immunoassay and compared with those from normal subjects (n = 20). The concentration of circulating ICAM-1, E-selectin and VCAM-1 was significantly increased in nasopharyngeal carcinoma. Correspondingly, VCAM-1 and E-selectin were significantly increased in laryngeal carcinoma, whereas only E-selectin was elevated in oral carcinoma. The concentrations of these adhesion molecules did not significantly differ with respect to the early and late stages of these carcinomas. Elevated levels of soluble adhesion molecules in the sera of cancer patients at three different head and neck regions, although appearing to be implicated in these tumour formations, may be unrelated to tumour progression.

Abstract
BACKGROUND Hepatic graft reperfusion is associated with inflammatory processes of unknown relevance to the fate of graft. This study aimed to clarify this relevance by histochemical analyses of human hepatic grafts. METHODS Paired tissue samples were taken at the end of cold preservation and 2 hr after reperfusion (n=39). From six additional grafts, biopsies were performed at the end of cold preservation only. Injury or inflammatory markers of sinusoidal endothelium (von Willebrand factor-related antigen [vWF]), Kupffer cells (25F9), platelets (CD62), neutrophil leukocytes (CD11b), interleukin (IL)-1beta, intercellular adhesion molecule (ICAM)-1, and HLA-DR were evaluated semiquantitatively by indirect immunoperoxidase staining. Steatosis was also evaluated by hematoxylin and eosin staining. RESULTS vWF, CD62+ platelet aggregation, CD11b+ leukocytes, and IL-1beta levels increased after reperfusion, and these levels correlated with prereperfusion levels. Not only vWF, CD62+ platelets, CD11b+ leukocytes, IL-1beta, ICAM-1, and steatosis after reperfusion, but also IL-1beta, ICAM-1, and steatosis before reperfusion correlated with postoperative peak transaminase. Furthermore, vWF, CD11b+ leukocytes, 25F9+ macrophages, and ICAM-1 after reperfusion were associated with primary graft nonfunction and strong expressions of ICAM-1 or HLA-DR with early acute rejection. Although some markers (IL-1beta, CD62+ platelets, and CD11b+ leukocytes) correlated with preharvesting parameters (donor age or length of intensive care unit stay), none showed any significant correlation with cold preservation. CONCLUSION Synergistic inflammatory events in the hepatic graft at reperfusion, which have a significant impact on the later clinical course, are largely defined and precipitated by injury or activation of nonparenchymal cells preceding reperfusion or even graft harvesting.

Abstract
BACKGROUND A possible role for intercellular adhesion molecules in tumor progression and metastasis has been strongly suggested. To investigate the effect of soluble intercellular adhesion molecule-1 (sICAM-1) on bladder cancer, sICAM-1 serum and urinary concentrations were measured in patients with superficial or invasive bladder cancer and in patients with prostatic hypertrophy. METHODS Serum and urine samples were obtained from 26 patients with transitional cell carcinoma of the bladder (mean age, 66.8 years) and 14 patients with benign prostatic hypertrophy (BPH; mean age, 70.5 years). Fifteen healthy volunteers served as control patients. Samples were collected before surgery and 5 days after surgery. The serum and urinary slCAM-1 levels were measured by an ELISA. RESULTS The preoperative serum concentration of sICAM-1 was significantly higher in patients with invasive bladder cancer (351.8+/-158.0 ng/mL) than in the healthy controls (233.1+/-96.1 ng/mL; P< 0.05) or BPH patients (224.7+/-80.5 ng/mL; P< 0.05). In addition, serum sICAM-1 levels were significantly higher in patients with tumors greater than 3 cm in size (412.7+/-147.6 ng/mL) than in patients with smaller tumors (246.6+/-101.2 ng/mL; P<0.05). Urinary sICAM-1 levels in patients with invasive bladder cancer were also significantly higher than in the patients with superficial cancer prior to surgery. CONCLUSION Our results suggested that sICAM-1 may play an important role in the progression of bladder cancer, and that elevated serum sICAM-1 levels may be related to tumor size.

Abstract
CD2 is a co-stimulatory receptor involved in T cell activation. Here we report on immunosuppressive effects of three mouse CD2 monoclonal antibodies (OX34, OX54, OX55) directed against non-overlapping epitopes of the rat CD2 receptor on various modes of T cell activation in vitro and in vivo. Although non-ligand-blocking OX54 and OX55, in concert, activated T cells through CD2 in vitro, they individually suppressed the mixed lymphocyte reaction (MLR) and significantly prolonged allograft survival after rat heart transplantation in vivo. Phenotype analysis revealed that OX55 significantly down-modulated CD2 in vivo, whereas OX54 depleted T cells. Graft rejection coincided with re-expression of CD2 and clearance of OX55 from serum, whereas T cell depletion by OX54 outlasted the period of graft survival. The most suppressive antibody, OX34, down-modulated CD2 and inhibited T cell activation through the TCR or CD2 and the MLR and prolonged median allograft survival time from 7 days in controls to 45 days in the absence of any additional treatment. Graft survival was clearly dose dependent and correlated with the duration of CD2 down-modulation and the presence of circulating CD2 antibody in serum. Importantly, the specific antibody production to a T cell-dependent antigen as demonstrated by immunization with keyhole limpet hemocyanin in vivo remained unaffected after treatment with OX34. These results demonstrate the pivotal role of CD2 signaling in mediating allogeneic immune reactions after vascularized organ transplantation while allowing specific humoral immune responses in vivo.

Abstract
Abstract
The CD2 glycoprotein has been implicated in both positive and negative regulation of T-cell mitogenesis. To study the involvement of CD2 in T-lymphocyte development and immune responses, we have analyzed two lines of CD2-null mice, each expressing a distinct class I major histocompatibility complex (MHC)-restricted T-cell receptor (TCR). In both situations, the absence of CD2 appeared to promote the positive selection of cells in a manner that is similar to that which occurs in the absence of CD5. Consistent with this, compound homozygotes that lacked both CD2 and CD5 showed evidence of enhanced positive selection even in the absence of a transgenic TCR. Despite the observed enhancement of positive selection, the lack of CD2 was associated with defects in proliferative responses and interferon-γ production when transgenic thymocytes and mature T lymphocytes were stimulated with the appropriate antigens. These findings raise the possibility that impaired sensitivity to selecting ligands in the thymus may provide a selective advantage that improves the efficiency of positive selection for certain TCRs. Furthermore, the results highlight the potential for a differential role for CD2 in thymocyte selection and T-cell immune responses.

Abstract
We have isolated cDNA encoding human telencephalin (TLN), a brain segment-specific neuronal adhesion molecule. Human TLN comprises an NH2-terminal signal peptide, an extracellular region with nine Ig-like domains, a single transmembrane region, and a COOH-terminal cytoplasmic tail. The NH2-terminal five Ig-like domains of TLN were closely related to those of intercellular adhesion molecules (ICAMs)-1 and -3. The TLN gene was mapped to the human chromosome 19p13.2, where the ICAM-1, -3, and -4 (LW) genes are located. Furthermore, we observed lymphocyte function-associated antigen-1 (LFA-1)-mediated adhesion of HL-60 cells on recombinant TLN protein, as well as on ICAM-1. However, the interaction of TLN with LFA-1 on HL-60 cells was divalent cation-independent and phorbol 12-myristate 13-acetate stimulation-independent. We conclude that TLN is a unique neuronal member of ICAM subgroup of the Ig superfamily and propose a novel type of interaction between the Ig superfamily molecule and integrin, which does not require the activation of integrin. TLN on the surface of telencephalic neurons may be a target molecule in the brain for LFA-1-expressing microglia and leukocytes in physiological or pathological conditions.

Abstract
Levels of circulating soluble intercellular adhesion molecule-1 (sICAM-1) are elevated in patients affected by solid malignancies; however, the cellular sources generating high levels of sICAM-1 remain to be characterized. Using conditioned media (CM) from seven ICAM-1-positive or -negative neoplastic cells, we demonstrate that tumour-derived interleukin 1alpha (IL-1alpha) significantly (P < 0.05) up-regulates the release of sICAM-1 by human umbilical vein endothelial cells. The intensity of the effect correlated with the amounts of IL-1alpha detectable in CM. Levels of ICAM-1 mRNA were also up-regulated by tumour-secreted IL-1alpha. The up-regulation of the shedding of sICAM-1 and of its expression at protein and mRNA level were completely reversed by the addition of anti-IL-1alpha neutralizing antibodies. Consistent with the in vitro data, tumour endothelia were strongly stained for ICAM-1 compared with autologous normal tissue endothelia. Taken altogether, our observations reveal an IL-1alpha-mediated tumour-endothelium relationship sustaining the shedding of sICAM-1 by endothelial cells. This is a general phenomenon in solid malignancies that correlates with the ability of neoplastic cells to secrete IL-1alpha rather than with their expression of ICAM-1 and/or histological origin. sICAM-1 has been previously shown to inhibit LFA-1/ICAM-1-mediated cell-cell interactions; therefore, the ability of neoplastic cells to secrete IL-1alpha is likely to represent a mechanism for their escape from immune interaction.

Abstract
Extranodal non-Hodgkin's lymphoma in the head and neck, especially T-cell lymphoma of the lethal midline granuloma (LMG) type, has unique clinical and histologic features differentiating it from other lymphomas. The authors measured soluble intercellular adhesion molecule-1 (ICAM-1) in sera from 12 patients with T-cell lymphoma of the LMG type and from 52 patients with other head and neck non-Hodgkin's lymphomas, by double-determinant immunoassay. The expression of ICAM-1 in lymphoma tissue was examined in 26 patients by the avidin-biotin immunoperoxidase method. The serum ICAM-1 levels were significantly higher in T-cell lymphoma of the LMG type than in other head and neck lymphomas or in healthy adult controls. Elevated levels of serum ICAM-1 were associated with increased levels of serum lactate dehydrogenase, poor prognosis, and impaired T-cell-dependent immune functions, both in T-cell lymphoma of the LMG type and in other head and neck lymphomas. When we monitored serum ICAM-1 levels in individual patients, the level decreased in the complete remission interval compared to before treatment and went up again when the lymphoma relapsed. Although the staining intensities of ICAM-1 in lymphoma cells were not related to serum ICAM-1 levels, a markedly intense expression of ICAM-1 was found on the angiocentric or angiodestructive lymphoreticular infiltrate region in the tissues from T-cell lymphoma of the LMG type. A higher serum ICAM-1 level and its tissue expression in T-cell lymphoma of the LMG type may be one of the clues to understanding this particular lymphoma. The serum ICAM-1 level could be an efficient parameter for monitoring the clinical course of head and neck non-Hodgkin's lymphomas.

Abstract
Rheumatoid arthritis is a systemic inflammatory disease of the joints and major internal organs that has an unknown aetiology. Cell adhesion molecules (CAMs) are expressed on the surface of cells, enabling homotypic and heterotypic cell-cell interactions that are fundamental in the process of the inflammatory reaction. Three major families of CAMs are now recognised, with numerous subtypes. Many of these molecules play an important role in the mechanism of disease in rheumatoid arthritis. E-Selectin and intercellular adhesion molecule (ICAM)-1 are upregulated on the synovial endothelium, while vascular cell adhesion molecule (VCAM)-1 plays an important role in the synovial lining layer cells and within the synovial stroma. The expression of CAMs may be blocked by monoclonal antibodies and modified by nonsteroidal anti-inflammatory drugs and disease-modifying antirheumatic drugs. This has very important implications in the therapy of rheumatoid arthritis.

Abstract
BACKGROUND The factors determining a basal cell carcinoma's (BCC's) growth pattern and invasive potential are not known. In other tumors it has been shown recently that the expression of cellular adhesion molecules may determine a tumor's invasive and metastatic potential. Integrins, cell surface molecules important in cell stroma interactions, are present on BCCs and may help regulate the tumor's growth pattern. OBJECTIVE We compared the expression of cellular adhesion molecules alpha 2 integrin, beta 1 integrin, intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), leukocyte function antigen 1a (LFA-1a), and E-selectin in different histological subtypes of basal cell carcinomas. METHODS BCCs were obtained from patients undergoing Mohs surgery. The BCCs were classified as nodular, micronodular, mixed, infiltrative, and basosquamous types and stained using an avidin-biotin-immunoperoxidase technique with antibodies against alpha 2 integrin, beta 1 integrin, ICAM, LFA-1a, VCAM-1, and E-selectin. RESULTS BCCs expressed alpha 2 and beta 1 integrin, but no significant differences in the amount or pattern of expression was seen in the different histologic subtypes. CONCLUSION The expression of integrins by BCCs by binding to the surrounding stroma may limit BCC's growth; however, their expression does not appear to correlate with their histological pattern.

Abstract
We examined ICAM-1 expression in 37 freshly dissociated renal-cancer cell populations. Immunoperoxidase analysis revealed that 31 of the 37 renal tumors expressed ICAM-1 to various degrees; ICAM-1 expression was significantly lower in tumor cells obtained from patients remaining tumor-free after a median follow-up of 60 months (mean value 24.4% +/- 21) than in tumor cells obtained from the relapsed patients (mean value 40.8% +/- 22), and the low expression of this molecule on the cell surface seemed to correlate with favorable clinical behavior. In 41 patients, the mean level of sICAM-I was 551 +/- 260 ng/ml, significantly higher than normal. However, sICAM-1 levels were significantly lower in the 20 tumor-free (mean 467 +/- 158 ng/ml) than in the 21 metastatic patients (mean 631 +/- 318 ng/ml). Eleven renal-cancer cell populations were cultured in order to examine the expression and release of ICAM-1. All of these cells were positive for ICAM-1 expression, which was elevated in 6 cases (> 50%) and low in the remaining 5 cases (18-35%). However, only the 5 cell populations expressing low levels of ICAM-1 released this molecule, showing an inverse correlation with cellular expression. Five of the cell populations were treated for 48 hr with rIFN-gamma, in these cells, both ICAM-1 expression and sICAM-1 levels increased, although sICAM-1 levels in the supernatants of the cell populations with constitutive high ICAM-1 expression remained very low.

Abstract
Adhesion molecules are involved in facilitating cell-mediated immune events. Because lymphocyte-epithelial cell interaction has been implicated in the pathogenesis of colonic inflammation, we analysed expression of a range of adhesion molecules on colonic epithelium in vitro and in vivo using flow cytometry, immunohistochemistry and in situ hybridization. Expression of ICAM-1 by cell lines HT29 and int407 was increased by proinflammatory cytokines interferon-gamma (IFN-gamma), tumour necrosis factor-alpha (TNF-alpha) and IL-1 but not by IL-6. Vascular cell adhesion molecule (VCAM) and E-selectin were not expressed. Immunohistochemistry using sections of inflamed colon from 16 patients with ulcerative colitis (UC), five patients with Crohn's disease (CD) and seven patients with normal colonoscopic biopsies, showed no expression of ICAM-1 on colonic epithelium. VCAM was seen in isolated lymphoid aggregates and E-selectin was expressed on endothelium. In situ hybridization showed no ICAM-1 or ICAM-3 mRNA in colonic epithelium. B7, the ligand for CD28, was not found on normal or inflamed colonic epithelium. The adhesion molecules ICAM-1, ICAM-3 and B7 are not involved in lymphocyte-epithelial cell interaction in the normal or inflamed colon. This may have implications for the development of T cell tolerance to intestinal luminal antigens.

Abstract
The objective of this study was to measure soluble intercellular adhesion molecule-1 (sICAM-1) in patients with Behçet's disease (BD) and to analyse the relationship of sICAM-1 levels with clinical and some laboratory measures of disease activity. Forty patients with BD fulfilling the International Study Group Criteria for the diagnosis of BD and 20 healthy controls were studied. Twenty patients had active, and 20 patients had inactive disease. Serum sICAM-1 was determined by a sandwich ELISA. The mean (+/- SD) sICAM-1 level was significantly higher in the whole BD group (297.3 +/- 86.6 ng/ml) than in the healthy controls (213 +/- 83.5 ng/ml; P < 0.05). The mean sICAM-1 levels in active and inactive BD patients were 315.7 +/- 76.3 ng/ml and 258.3 +/- 73.3 ng/ml, respectively. The mean sICAM-1 level in active patients was significantly higher than in inactive patients and healthy controls (P < 0.02 and P < 0.001, respectively). No statistically significant difference in mean sICAM-1 levels was found between inactive BD patients and healthy controls (P > 0.05). There was no statistically significant difference between the mean sICAM-1 levels of active patients with (351.3 +/- 77.2 ng/ml) or without vascular lesions (292 +/- 68.8; P > 0.05). In spite of a positive correlation between disease activity and both erythrocyte sedimentation rate and C-reactive protein (CRP; P < 0.01), we found no correlation between sICAM-1 and either of them (P > 0.05). The elevated levels of sICAM-1 may be due to endothelial cell activation and/or damage or may be the result of inflammation.(ABSTRACT TRUNCATED AT 250 WORDS)
