Abstract
BACKGROUND AND AIMS The complement system, particularly the alternative complement pathway, may contribute to vascular damage and development of cardiovascular disease (CVD). We investigated the association of factor D, the rate-limiting protease in alternative pathway activation, with adverse cardiovascular outcomes. METHODS In 2947 participants (50.6% men, 59.9 ± 8.2 years, 26.5% type 2 diabetes [T2D], oversampled) we measured markers of low-grade inflammation (LGI, composite score, in SD) and, endothelial dysfunction (ED, composite score, in SD), carotid intima-media thickness (cIMT, μm), ankle-brachial index (ABI), CVD (yes/no) and plasma concentrations of factor D (in SD). Associations were estimated using multiple linear and logistic regression, adjusting for demographic, lifestyle, and dietary factors. RESULTS Factor D (per SD) significantly associated with LGI (0.171 SD [0.137; 0.205]), ED (0.158 SD [0.123; 0.194]) and CVD (OR 1.15 [1.04; 1.27]) but not significantly with cIMT (-6.62 μm [-13.51; 0.27]) or ABI (-0.003 [-0.007; 0.001]). Interaction analyses show that factor D more strongly associated with ED in non-diabetes (0.237 SD [0.189; 0.285] than in T2D (0.095 SD [0.034; 0.157]), pinteraction <0.05. These results were largely corroborated by additional analyses with C3 and C3a. In contrast, factor D inversely associated with cIMT in non-diabetes (-13.37 μm [-21.84; -4.90]), but not in T2D (4.49 [-7.91; 16.89]), pinteraction <0.05. CONCLUSIONS Plasma factor D is independently associated with LGI, ED, and prevalent CVD but not with ABI or cIMT. Hence, greater plasma factor D concentration in CVD may potentially induce complement activation which, in turn, might contribute to further disease progression via a process that may involve inflammation and endothelial dysfunction but was not directly related to atherosclerosis or arterial injury. The observation that, in participants without diabetes, factor D associated with worse ED but smaller cIMT warrants further investigation.

Abstract
Background Tumor necrosis factor alpha (TNF-α) plays a central role in the initiation and maintenance of immune responses to periodontopathic bacteria. However, excess TNF-α leads to dysregulated immune responses and progression of periodontitis. Porphyromonas gingivalis (P. gingivalis) invades gingival epithelial cells and then multiplies and survives for a long period. Additionally, increment of TNF-α in periodontal sites is associated with a high prevalence of gram-negative anaerobes such as P. gingivalis. However, it has not been determined whether TNF-α affects invasion of P. gingivalis in periodontal tissues. Results We examined the effect of TNF-α on invasion of P. gingivalis in gingival epithelial cells and clarified the mechanism by which TNF-α augments invasion of P. gingivalis. Invasion of P. gingivalis into Ca9-22 cells was augmented by stimulation with TNF-α and it was inhibited by treatment with an antibody to TNF receptor-1. TNF-α increased production of ICAM-1, and P. gingivalis invasion was inhibited by an antibody to ICAM-1 in Ca9-22 cells. Silencing of Rab5 mRNA inhibited P. gingivalis invasion. Furthermore, the JNK inhibitor SP600125 inhibited invasion of P. gingivalis and also decreased the active form of Rab5 in Ca9-22 cells. Conclusion TNF-α augments invasion of P. gingivalis in human gingival epithelial cells through increment of ICAM-1 and activation of Rab5. These phenomena may contribute to persistent infection of P. ginigvalis and prolongation of immune responses in periodontal tissues.

Abstract
We investigated the cytokine/chemokine secretions and alteration of protein expression from peripheral blood mononuclear cells (PBMCs) cocultured with adult liver flukes (Opisthorchis viverrini) for 6 to 24 h. PBMC-derived proteins were identified by two-dimensional electrophoresis and mass spectrometry, and the cytokines/chemokines in the supernatant were assessed using a cytokine array. Exposure to O. viverrini induced increases in secretion of proinflammatory cytokines, costimulating protein, adhesion molecules, and chemotactic chemokines relative to untreated controls. In contrast, secretion of the CD40 ligand, interleukin 16, and macrophage inflammatory protein 1β decreased. Proteomic analysis revealed that expression of 48 proteins was significantly altered in PBMCs stimulated with O. viverrini. Annexin A1 (ANXA1) was selected for further study, and immunoblotting showed upregulation of ANXA1 expression in PBMCs after 12 and 24 h coculture with liver flukes. In an in vivo study, transcription and translation of ANXA1 significantly increased in livers of hamsters infected with O. viverrini at 21 days and from 3 months onwards compared to normal controls. Interestingly, immunohistochemistry revealed that ANXA1 was present not only in the cytoplasm of inflammatory cells but also in the cytoplasm of cholangiocytes, which are in close contact with the parasite and its excretory/secretory products in the biliary system. Expression of ANXA1 increased with time concomitant with bile duct enlargement, bile duct formation, and epithelial cell proliferation. In conclusion, several cytokines/chemokines secreted by PBMCs and upregulation of ANXA1 in PBMCs and biliary epithelial cells might have a role in host defense against O. viverrini infection and tissue resolution of inflammation.

Abstract
Acute limb ischemia is a common medical condition resulting from arterial embolization, in situ thrombosis, trauma, and other causes. The severity of injury is related to the duration of ischemia and the effects of reperfusion. Metabolic consequences of reperfusion injury can be variable, ranging from transient symptoms in the lower extremity to systemic inflammation with multiple organ dysfunction. This article provides an overview of some of the key mediators of reperfusion injury. Additional discussion is focused on the clinical effects of reperfusion in the extremity, as well as the pulmonary, cardiac, and renal organ systems. A better understanding of these processes may result in improved patient outcomes and decreased mortality.

Abstract
Ulcerative colitis (UC) and Crohn's disease (CD) are idiopathic inflammatory bowel diseases (IBDs) that are characterized by chronic periods of exacerbation and remission. Research into the immunopathogenesis of IBD adds support to the theory that the disease results from a dysfunctional regulation of the immune system that leads to the polarization of intestinal immune cells toward a Th1 (T helper) response. The immunologic factors that mediate alterations in intestinal homeostasis and the development of intestinal mucosal inflammation have been at the forefront of IBD research. Cytokines, which are important regulators of leukocyte trafficking and apoptotic cell death, have emerged as essential immune molecules in the pathogenesis of IBD. In this study, recent advances in the understanding of the dynamism of cytokines and the consequences for mucosal immunity and inflammation in IBD are discussed. Furthermore, this study highlights the potential use of cytokines, anti-cytokine antibodies, and cytokine-related biologic therapies as novel targets for the treatment of IBD.

Abstract
Adenosine has been described as playing a role in the control of inflammation, but it has not been certain which of its receptors mediate this effect. Here, we generated an A2B adenosine receptor-knockout/reporter gene-knock-in (A2BAR-knockout/reporter gene-knock-in) mouse model and showed receptor gene expression in the vasculature and macrophages, the ablation of which causes low-grade inflammation compared with age-, sex-, and strain-matched control mice. Augmentation of proinflammatory cytokines, such as TNF-alpha, and a consequent downregulation of IkappaB-alpha are the underlying mechanisms for an observed upregulation of adhesion molecules in the vasculature of these A2BAR-null mice. Intriguingly, leukocyte adhesion to the vasculature is significantly increased in the A2BAR-knockout mice. Exposure to an endotoxin results in augmented proinflammatory cytokine levels in A2BAR-null mice compared with control mice. Bone marrow transplantations indicated that bone marrow (and to a lesser extent vascular) A2BARs regulate these processes. Hence, we identify the A2BAR as a new critical regulator of inflammation and vascular adhesion primarily via signals from hematopoietic cells to the vasculature, focusing attention on the receptor as a therapeutic target.

Abstract
OBJECTIVE Rheumatoid arthritis is a chronic inflammatory autoimmune disease with proinflammatory cytokines involved in its pathogenesis. Recently in vitro as well as in vivo studies have shown that iloprost, a stable prostacyclin analogue, can reduce the release of these cytokines. This study was performed to further investigate the anti-inflammatory effects of iloprost by determining plasma adhesion molecules as markers of endothelial cell activation, and plasma thrombomodulin as a parameter of endothelial cell injury in patients with rheumatoid arthritis receiving oral iloprost therapy. METHODS Plasma thrombomodulin levels and the values of the plasma adhesion molecules VCAM-1 (vascular cell adhesion molecule 1), E-selectin (CD62E), and ICAM-1 (intercellular adhesion molecule 1, CD 54) were measured by ELISA during a 7-day period of treatment with orally-administered iloprost in 14 patients with active rheumatoid arthritis. Finally, the same parameters were determined at the end of the observation period (1 week after the end of therapy). In addition, the disease activity was measured using the DAS (disease activity score) as well as the patients' self-assessed pain severity, and correlated with the changes of plasma adhesion molecule and thrombomodulin levels. RESULTS The plasma levels of all three adhesion molecules as well as of thrombomodulin significantly decreased under therapy with oral iloprost. After 1 week (day 7 of therapy), the mean percent changes from day 0 were -20.1% for VCAM-1 (p = 0.008), -21.2 for ICAM-1 (p = 0.003), -24.6% for E-selectin (p = 0.001), and -21.7% for thrombomodulin (p = 0.003). This decrease lasted up to 1 week after the end of therapy in the case of VCAM-1 (p = 0.023) and ICAM-1 (p = 0.001). Further analysis of the results revealed additional significant correlations between different parameters of clinical disease activity, thrombomodulin and adhesion molecules. CONCLUSION This study showed hints towards clinical effects in patients with rheumatoid arthritis receiving oral iloprost therapy. Pathophysiologically, the decrease of adhesion molecules points at an immunomodulating effect of iloprost. The observed thrombomodulin-lowering effect of iloprost may indicate stabilisation of endothelial cell function by diminishing endothelial cell injury.

Blood vessel activation in inflammatory diseases is triggered by a myriad of different factors that partially reveal opposite activities on endothelial cells (EC). For example, inflammatory cytokines (IC) inhibit EC proliferation and induce cell adhesiveness for leukocytes. In contrast, angiogenic growth factors (AGF) activate EC proliferation and inhibit cell adhesiveness for leukocytes. In consequence, IC and AGF may induce two different activation phenotypes in EC that appear in a temporally and/or spatially coordinated manner in inflammatory tissues. Human guanylate binding protein-1 (hGBP-1) is a member of the large GTPase protein family. New results demonstrate that hGBP-1 is a specific marker of IC-activated EC that allows to differentiate the IC- and AGF-activated phenotype of EC at the single cell level, both in vitro and in vivo. In addition, hGBP-1 is the key mediator of the inhibitory effects of IC on EC proliferation and invasiveness. Both the expression pattern of hGBP-1 and its activity in EC supported the hypothesis that IC- and AGF-activation induce distinct adversely related phenotypes in EC. In future, hGBP-1 may be used as a marker to monitor the IC-induced phenotype of EC in inflammation and may also be exploited as a target to modulate EC activity in inflammatory diseases and tumor angiogenesis.

Abstract
Neutrophils are recognized as major cellular mediators of inflammation. They contain specific and highly regulated mechanisms for controlling the expression of adhesion molecules that allow for their tethering and migration into inflammatory sites. These adhesion molecules not only are activated by exogenous pollutants but are regulated by endothelial and epithelial cell signals. Lipid mediators, such as platelet-activating factor, reactive oxygen and nitrogen species, and cytokines from airway epithelial cells, further control neutrophil functions such as infiltration and activation resulting in an increase in respiratory burst activity and release of granule enzymes, such as elastase. Furthermore, virus and bacteria products affect inflammation by increasing secondary epithelial mediators. However, once the endogenous or exogenous agents are expelled, neutrophil populations are programmed to die and are cleared by macrophage phagocytosis.

Abstract
Sequential interactions between several adhesion molecules and their ligands regulate lymphocyte circulation and leukocyte recruitment to inflammatory foci. Adhesion molecules are, therefore, central and critical components of the immune and inflammatory system. We review the evidence that tobacco smoking dysregulates specific components of the adhesion cascade, which may be a common factor in several smoking-induced diseases. Smoking causes inappropriate leukocyte activation, leukocyte-endothelial adhesion, and neutrophil entrapment in the microvasculature, which may help initiate local tissue destruction. Appropriate inflammatory reactions may thus be compromised. In addition to smoke-induced alterations to membrane bound endothelial and leukocyte adhesion molecule expression, which may help explain the above phenomena, smoking has a profound influence on circulating adhesion molecule profiles, most notably sICAM-1 and specific sCD44 variants. Elevated concentrations of soluble adhesion molecules may simply reflect ongoing inflammatory processes. However, increasing evidence suggests that specific soluble adhesion molecules are immunomodulatory, and that alterations to soluble adhesion molecule profiles may represent a significant risk factor for several diverse diseases. This evidence is discussed herein.

Abstract
Postdiarrheal hemolytic uremic syndrome is caused by Shiga toxin (Stx)-producing Escherichia coli. It was shown previously that the baboon, like the human, has glycolipid receptors for Stx in the gut and the kidney and that a single 50- to 200-ng/kg intravenous dose of purified Stx-1 results in thrombocytopenia, hemolytic anemia, and renal thrombotic microangiopathy. For further characterization of factors that modulate disease expression, the baboon's response to the intravenous administration of 100 ng/kg Stx-1 given either rapidly as a single bolus or slowly as four 25-ng/kg doses at 12-h intervals was compared. Animals that received the Stx-1 as a single dose developed thrombocytopenia, schistocytosis, and acute renal failure. Urinary but not plasma tumor necrosis factor-alpha concentrations rose significantly by 6 h and then declined rapidly. Urinary and plasma interleukin-6 concentrations rose later. Glomeruli showed reduced patency of capillary loops, fragmented red blood cells, fibrin and platelet microthrombi, necrosis and detachment of endothelial cells, and accumulation of flocculent material in subendothelial spaces. Damage to tubular epithelium and peritubular capillary endothelium also was seen. Animals that received four divided doses of Stx-1 developed no clinical or histologic features of hemolytic uremic syndrome. It is concluded that in the primate model, disease expression is modulated by the rate of Stx administration, and it is speculated that in the human, the rate of Stx absorption from the gut is one determinant of disease severity.

Abstract
Studies evaluating cytokine production under normothermic cardiopulmonary bypass (CPB) are limited. We evaluated cytokine production, levels of thrombomodulin (TM), and soluble endothelium-derived adhesion molecules (ICAM-1) under normothermic CPB with and without heparin-bonded circuits. Nine patients treated with non heparin-bonded circuits (control group), and seven patients treated with heparin-bonded circuits (heparin group) were the subjects. Granulocyte elastase (G-E), and interleukin (IL) -6 and IL-8 were chosen as proinflammatory mediators, and TM and ICAM-1 served as indicators for endothelial damage. Blood samples were obtained before CPB, 30 minutes after initiation of CPB, at the termination of CPB, and 2 and 24 hours after CPB. G-E values in the heparin group were lower than those in the control group after 30 minutes of CPB. A G-E surge occurred at the end of CPB, and IL-6 and IL-8 surges were observed 2 hours after CPB in both groups. TM and ICAM-1 values, which were reduced at the initiation of CPB, returned to initial levels 2 hours after CPB, and exceeded them 24 hours after CPB compared with preCPB levels. Both groups showed similar changes. We conclude that there are no significant differences in serial G-E, IL-6, IL-8, TM, or ICAM-1 levels between the heparin and control groups during or after normothermic CPB for 2 to 3 hours.

Abstract
Protection against infectious pathogens at mucosal surfaces is dependent on local antibody responses, production of inflammatory mediators, and recruitment of immune effector cells to the site of infection. Since Th1 and Th2 cells produce cytokines with pro- and anti-inflammatory activities, immunization with vaccines that induce these T-cell subtypes may regulate the subsequent inflammatory response to infection. We have demonstrated that immunization of mice with pertussis whole-cell or acellular vaccines (Pw or Pa) selectively induces Th1 and Th2 cells, respectively. In this study we have used a murine respiratory-infection model to demonstrate that priming with a Th1- or Th2-inducing pertussis vaccine can influence the local inflammatory response and immune effector cells in the lung following aerosol challenge with Bordetella pertussis. Analysis of bronchoalveolar lavage (BAL) fluid taken during the course of B. pertussis infection of naïve mice or mice immunized with Pw revealed an early influx of neutrophils and local production of interleukin 1beta (IL-1beta) in the lungs. In contrast, neutrophil infiltration and IL-1beta production were not observed following challenge of mice immunized with the Th2-inducing Pa. Conversely, during infection local production of IL-6 and IL-1ra was significantly greater in mice immunized with Pa than in those immunized with Pw. Studies of knockout mice revealed neutrophil and lymphocyte infiltration in the lungs following B. pertussis infection of IL-4-defective (IL-4(-/-)) mice but not in wild-type mice immunized with Pa. Furthermore, the levels of IL-1beta, IL-6, and IL-1ra in Pa-immunized IL-4(-/-) mice were comparable to those in mice immunized with Pw. These results demonstrate distinct influences of Th1- and Th2-inducing vaccines on the protective inflammatory responses in the lungs following challenge with B. pertussis and implicate IL-4 as an important regulator of inflammatory-cell recruitment.

Abstract
BACKGROUND Plasma levels of soluble intercellular adhesion molecule-1 (sICAM-1) have been shown to predict activities of inflammatory disorders and malignancies. However, it is unknown whether the plasma level of sICAM-1 is increased in patients with acute myocardial infarction (AMI) with coronary intervention and whether the levels have any diagnostic or predictive values for vascular disease activity in patients with AMI. METHODS We prospectively observed the time course of the plasma sICAM-1 levels in 20 patients with AMI whose infarct-related coronary artery was successfully recanalized by emergency balloon angioplasty. sICAM-1 was measured by enzyme-linked immunoassay. RESULTS At admission, 48 hours, 1 week, and 2 weeks after angioplasty, sICAM-1 levels were significantly elevated in patients who had early (3 weeks) restenosis develop compared with those who did not (p < 0.05). At the other time points examined, there was a tendency of higher sICAM-1 levels in patients with than without restenosis (0.06 < p < 0.09). The relation of sICAM-1 levels and total white blood cell counts, neutrophil counts, or numbers of diseased major coronary artery branches was not statistically significant. CONCLUSIONS A persistent increase in plasma sICAM-1 levels may indirectly implicate vascular inflammation, which could predict the risk of early coronary restenosis after emergency angioplasty in patients with AMI. Hence, measurements of sICAM-1 in patients with AMI would serve as a potentially useful predictor of the risk of early postangioplasty restenosis.

Abstract
We measured sICAM-1 in paired samples of serum and cerebrospinal fluid (CSF) from patients with an attack of multiple sclerosis (MS) (n = 50) and patients with acute monosymptomatic optic neuritis (ON) as a possible first attack of MS were also included (n = 25). Based on calculations of extended indices we found evidence of intrathecal synthesis of sICAM-1 both in patients with clinically definite MS and in patients with idiopathic ON compared to neurological control subjects. The amount of intrathecally synthesized sICAM-1 correlated significantly to the CSF leukocyte count and to the concentration of myelin basic protein in the CSF. The serum concentrations of sICAM-1 were not increased in patients with demyelinating disease compared to the neurological control subjects.

Abstract
Tumor necrosis factor alpha (TNF-alpha) has been suggested to play a critical role in indomethacin-induced gastric mucosal damage, so we evaluated its mucosal level and its relationship with prostaglandin E2 and neutrophils in indomethacin-induced gastric mucosal injury in rats. Indomethacin caused a time- and dose-dependent increase in gastric mucosal erosion, which was accompanied by a reduction in prostaglandin E2 followed by an increase in TNF-alpha level and neutrophil infiltration in the gastric mucosa. Pretreatment with exogenous prostaglandin E2 totally abolished indomethacin-induced gastric mucosal injury and the TNF-alpha increase. Depletion of neutrophils by methotrexate or reduction of TNF-alpha concentration by pentoxifylline markedly reduced indomethacin-induced mucosal damage. Pentoxifylline but not methotrexate prevented the increase in mucosal TNF-alpha level induced by indomethacin. It is suggested that depletion of prostaglandin E2 followed by an increase of TNF-alpha production and neutrophil infiltration in the gastric mucosa are important sequential processes in indomethacin-induced ulceration. Prevention of one of these processes would inhibit ulcer formation.

Abstract
Abstract
IL-4 is an immunoregulatory cytokine that has in vitro and in vivo anti-inflammatory actions. In this study we investigated whether endogenously produced IL-4 modulates inflammatory processes that occur after Abs bind to target tissue by comparing the severity of glomerulonephritis induced by heterologous anti-glomerular basement membrane Abs in wild-type (IL-4+/+) mice to that of glomerulonephritis induced in homozygous IL-4 gene knockout (IL-4−/−) mice. Two hours after Ab injection, IL-4−/− mice had significantly higher intrarenal intercellular adhesion molecule-1 mRNA expression and intraglomerular neutrophil accumulation than the IL-4+/+ group. Treatment of IL-4−/− mice with recombinant murine IL-4 at the time of disease induction reduced intercellular adhesion molecule-1 expression and neutrophil influx to levels observed in IL-4+/+ kidneys. Four days after Ab administration, untreated IL-4−/− mice developed significantly greater urinary protein excretion, intracapillary fibrinogen deposits, and glomerular hypercellularity than IL-4+/+ mice. These results demonstrate that endogenous IL-4 suppresses neutrophil influx and limits tissue damage in Ab-induced glomerulonephritis, suggesting that IL-4 is an important regulator of acute inflammatory processes.

Abstract
ICAM-1, a transmembrane glycoprotein promoting adhesion in immunologic and inflammatory reactions, was found to be increased on nasal epithelial cells of patients with allergic rhinitis. Loratadine, an H1-blocker, was found to reduce in vitro the expression of ICAM-1 on nasal epithelial cells. A double-blind, parallel-group study was carried out during the pollen season to compare the effect of two H1-blockers, cetirizine (10 mg OD) and loratadine (10 mg OD), on the release of soluble ICAM-1 in nasal secretions. A group of untreated patients was used as a control group. sICAM-1 was measured by enzyme immunoassay before and after 2 weeks of treatment. Symptoms were significantly decreased in the actively treated groups. sICAM-1 levels were unchanged in the control group but were significantly reduced in the two treated groups (P < 0.015, Wilcoxon's W test). This study shows that two H1-blockers, loratadine and cetirizine, have a similar effect on sICAM-1 released in nasal secretions during the pollen season.

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
The mechanism(s) of action responsible for the anti-inflammatory effects mediated by interferon (IFN)-beta are still elusive although suggestions include anti-viral effects, the enhancement of natural killer (NK) or suppressor T cell activity and opposition to the effects of inflammatory cytokines. As vascular endothelial cells are active participants in inflammatory and demyelinating processes, we decided to examine the effects of IFN-beta on the expression of major histocompatibility complex (MHC) gene products and intercellular adhesion molecule (ICAM)-1 on human vascular endothelial cells (ECs). Human umbilical ECs demonstrated constitutive expression of ICAM-1 and MHC class I molecules but did not express MHC class II molecules. Basal expression of ICAM-1 molecules was enhanced by TNF alpha and to a lesser extent by IFN-beta, but was not affected by IFN-gamma. MHC class I expression on ECs was enhanced by IFN-beta, IFN-gamma, and tumor necrosis factor (TNF)-alpha. Furthermore, a synergistic effect was observed to combinations of these interacting cytokines. Incubation of ECs with IFN-gamma, but not IFN-beta, induced class II expression in a dose dependent manner. Moreover, co-incubation of ECs with IFN-beta and IFN-gamma resulted in significant down-regulation of class II molecules expression which was directly dependent on IFN-beta concentration. Northern blot analysis of DR alpha and Beta 2-microglobulin mRNA expression suggested that cytokine-mediated regulation of MHC molecules is at the transcriptional level, while modulation of ICAM-1 expression appears to be at the transcriptional as well as post-transcriptional level. Thus, our study demonstrated that IFN-beta and interacting cytokines exert complex immunoregulatory effects on endothelial cells with differential modulatory effects on various cell surface markers. Understanding the biological significance of these immunomodulatory effects mediated by IFN-beta may have important implications for cytokine-based strategies in the treatment of inflammatory and autoimmune diseases.

Abstract
The present study was designed to establish (i) the effects of cytokines on soluble ICAM-1 (sICAM-1) production by human synovial cells (SC) and ICAM-1 expression on these cells, and (ii) the effects of sICAM-1 on lymphocyte-SC adhesion. sICAM-1 production was enhanced in parallel with ICAM-1 expression by IL-1 beta, TNF-alpha and IFN-gamma. IL-4 showed no effects on ICAM-1 expression. In contrast with the transient elevation of cell-associated ICAM-1 by IL-1 beta, which peaked 36 h after stimulation and declined thereafter, sICAM-1 continued to accumulate in culture supernatants even after 48 h. Purified sICAM-1 was obtained from a 48 h culture synovial cell supernatant by affinity chromatography using ICAM-1 monoclonal antibody. The purified sICAM-1 significantly inhibited adhesion of lymphocytes and monocytes to cytokine-stimulated synovial cells. These results suggest that sICAM-1 may modulate chronic synovitis by inhibiting ICAM-1-mediated cell-to-cell adhesion.
