Vascular cell adhesion molecule--1 expression is obligatory for endotoxin-induced myocardial neutrophil accumulation and contractile dysfunction

BACKGROUND: Sepsis-induced cardiac dysfunction occurs commonly in critically ill patients and is associated with high mortality rates. Neutrophils play a central role in sepsis-induced lung and liver injury; however, the mechanism of sepsis-induced cardiac dysfunction remains unclear. Vascular cell adhesion molecule-1 (VCAM-1) has been implicated in neutrophil-mediated liver injury during endotoxemia and is also expressed in myocardium. The purposes of this study were to examine the temporal relationship of myocardial VCAM-1 expression with neutrophil accumulation during endotoxemia and to determine whether VCAM-1 mediates neutrophil accumulation and cardiac dysfunction during endotoxemia. METHODS: Mice were subjected to lipopolysaccharide (LPS; 0.5 mg/kg, intraperitoneally). Myocardial VCAM-1 expression and neutrophil accumulation were determined by immunofluorescence staining. Cardiac performance with or without VCAM-1 blocking antibody (5 mg/kg, intravenously) was determined by the Langendorff technique. RESULTS: LPS caused a time-dependent increase in both myocardial VCAM-1 expression and neutrophil accumulation. At 6 hours after LPS, the immunofluorescent intensity for VCAM-1 increased from 2.5 +/- 0.6 x 10(6) in saline solution controls to 19.9 +/- 3.5 x 10(6) (P <.05, analysis of variance), and neutrophil count increased from 2.4 +/- 1.7/mm(2) in saline solution controls to 13.0 +/- 2.5/mm(2) (P <.05). Left ventricular developed pressure was decreased maximally at 6 hours after LPS compared with saline solution controls (29.1 +/- 1.1 mm Hg vs 53.1 +/- 3.9 mm Hg; P <.05). Treatment with VCAM-1 monoclonal antibody abrogated both myocardial neutrophil accumulation and cardiac dysfunction during endotoxemia. CONCLUSIONS: LPS-induced myocardial dysfunction is associated with increased expression of VCAM-1 and with neutrophil accumulation. Blockade of VCAM-1 abrogates myocardial neutrophil accumulation and preserves cardiac function during endotoxemia, which supports a role for VCAM-1 as a therapeutic target for myocardial protection during sepsis.     

Detection of soluble intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 in both cerebrospinal fluid and serum of patients after aneurysmal subarachnoid hemorrhage

OBJECT: The aim of this study was to explore whether levels of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) are elevated in the cerebrospinal fluid (CSF) and serum of patients after aneurysmal subarachnoid hemorrhage (SAH). METHODS: This prospective clinical study focused on 21 patients who had recently suffered an SAH due to aneurysmal rupture and 15 control patients with hydrocephalus who had no other central nervous system disease. Cerebrospinal fluid and serum samples obtained within the first 3 days and on the 5th and 7th days of SAH were assayed for ICAM-1 and VCAM-1 by using quantitative enzyme-linked immunosorbent assays. Levels of soluble forms of ICAM-1 (p = 0.00001) and VCAM-1 (p = 0.009) in the patients' CSF and those of ICAM-1 (p = 0.00001) and VCAM-1 (p = 0.00001) in their serum were found to be elevated after SAH compared with levels in the CSF and serum of control patients with hydrocephalus. In addition, when the authors compared the increased levels of adhesion molecules in the CSF and serum of patients after SAH, the only statistically insignificant difference that they found was between the levels of VCAM-1 in serum obtained on Days 5 and 7 after SAH (p = 0.27). CONCLUSIONS: Adhesion molecules are a group of macromolecules that may participate in the inflammatory process, a common pathway leading to vasospasm after SAH. Leukocyte adherence to the vascular endothelium, which is induced by adhesion molecules, has been believed to be the initial signal of the development of vasospasm. The authors have demonstrated the synchronized elevation of two adhesion molecules in both CSF and serum following aneurysmal SAH. Blocking of ICAM-1 as well as VCAM-1 by monoclonal antibodies post-SAH may provide a beneficial effect on vasospasm.     

DNA microarray-based gene expression profiles of cytomegalovirus infection and acute rejection in liver transplants

An association between cytomegalovirus (CMV) infection and alloresponse has been suggested. CMV increases inflammation and adhesion molecule expression in graft, and induces cytokines and growth factors, linked with transplant vasculopathy and chronic rejection. We have investigated the gene expression of various inflammatory factors in the CMV-associated immune response and compared this with the immune response of acute rejection in liver transplants by using DNA microarray technology. Gene expression was studied at mRNA level in biopsies from liver transplant patients experiencing CMV infection or acute rejection. RNA extracted from liver grafts after reperfusion was used as control material. Among the strongly upregulated genes in the specimens obtained from liver transplants during CMV infection were IFN-gamma, caspases 1 and 3, granzymes A and B, TGF-beta receptors II and III, IL-10 receptor alpha, VCAM-1, TNF receptor, IL-4, TNF-alpha, IL-10, IL-2 receptor beta, IL-1beta, PDGF-receptor beta, vascular adhesion protein-1, TGF-beta2, and ICAM-1. In biopsies with acute liver allograft rejection, the most significantly upregulated genes were MHC class II, IFN-gamma, caspases 1 and 3, IL-2R beta and gamma, granzymes A and B, VLA-4, L-selectin, E-selectin, VCAM-1, and IL-1beta. Upregulated genes common for CMV and alloresponse were granzyme A and B, E-selection, IFN-gamma, VCAM-1, VLA-4, TNF, caspases 1, 3, and 8, and PDGF. Microarray analysis defined different entities in the immune responses of CMV infection and acute rejection. The differences and similarities of the gene expression profiles related to those in CMV infection and rejection may help to understand the intragraft immunologic events.     

Renal expression of ICAM-1 and VCAM-1 in ANCA-associated glomerulonephritis--are there differences among serologic subgroups?

BACKGROUND: Antineutrophil cytoplasmic autoantibodies (ANCA) play a role in the expression of adhesion molecules. Differences in ANCA test results in ANCA-associated vasculitis may provide differences in their renal expression. PATIENTS AND METHODS: We assessed the renal expression of ICAM-1 and VCAM-1 with monoclonal antibodies in 19 patients with ANCA-vasculitis: 7 microscopic polyangiitis, 5 Wegener's granulomatosis, 4 renal-limited vasculitis and 3 Churg-Strauss disease. Immunofluorescence and ELISA for myeloperoxidase (MPO) and proteinase 3 (PR3) were performed for ANCA-testing. 10 normal renal tissues were used as controls. RESULTS: The ANCA staining pattern was perinuclear in 14 patients, with MPO-ANCA 31 - 220 EU/ml, and cytoplasmic in 5, with PR3-ANCA 37 - 144 EU/ml. Abnormal tubular expression of ICAM-1 and VCAM-1 was seen in more than 80% of biopsies and abnormal expression of VCAM-1 in glomerular tuft was seen in 60%. Glomerular tuft stains of ++ or +++ for VCAM-1 were observed in 10% of renal biopsies from MPO-ANCA-GN patients, but in 60% of biopsies from PR3-ANCA-GN patients (Fi = 8.538, p = 0.03). IN CONCLUSION: De novo expression of VCAM-1 on glomerular tuft suggests that the endothelial cells play a role in ANCA-GN. De novo glomerular expression of VCAM-1 is associated more with ANCA directed against PR3 than with ANCA directed against MPO. Upregulated glomerular expression of VCAM-1 may reflect a higher histological activity in patients with PR3-ANCA, and supports the existence of specific immune activation mechanisms in the different serologic subgroups in ANCA-GN. The de novo tubular expression of ICAM-1 and VCAM-1 suggests that the epithelial cells may participate in adhesive interactions in ANCA-GN.     

Serum inflammatory adhesion molecules and high-sensitivity C-reactive protein correlates with delayed ischemic neurologic deficits after subarachnoid hemorrhage

BACKGROUND: The purpose of the present study was to investigate the relationship between serum concentrations of the immunoglobulin-like superfamily, selectins, hsCRP, and the development of DIND in patients with aneurysmal SAH. METHODS: Serum ICAM-1, VCAM-1, E-selectin, P-selectin, L-selectin, and hsCRP were measured in 33 patients with SAH who underwent aneurysmal clipping within 48 hours of the onset of symptoms. Serum samples were obtained during the early period (day 0) and the late period (day 7). RESULTS: The serum concentrations of ICAM-1 (P = .009), VCAM-1 (P = .0383) and hsCRP (P = .0014) during the early period were significantly higher in patients with SAH than in control patients. Further, serum hsCRP concentration during the late period was significantly higher in patients with SAH than in control patients (P = 0033). Finally, serum concentrations of ICAM-1, VCAM-1, and hsCRP during the early (P = .0055, P = .0266, and P = .0266) and late (P = .0423, P = .0041, and P = .0004) period were significantly higher in patients with DIND than in patients without DIND. CONCLUSIONS: Serum levels of ICAM-1, VCAM-1 and hsCRP during the early and late period following SAH correlate with DIND.

Relationship between testosterone and indexes indicating endothelial function in male coronary heart disease patients

Aim： To investigate the relationship between androgen level and the indexes indicating endothelial function in male patients with coronary heart disease （CHD）. Methods： We registered the following data for 106 50-70-year-old men： age, weight, blood lipid, including total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglyceride, whether a smoker, sugar levels, blood pressure, free testosterone （FT）, vascular cell adhesion molecule- 1 （VCAM- 1） and the intima-media thickness （IMT） of common carotid artery, common carotid diameter, maximum velocity in systolic phase, minimum velocity in diastolic phase and resistent index. Among the 106 men, 51 were patients with CHD. The relationships between FT level, VCAM-1 concentration and IMT were examined, respectively, using a stepwise linear regression technique among all the 106 men. Results： There was no statistical difference in terms of age, blood pressure, whether a smoker, sugar levels, HDL-C, minimum velocity in diastolic phase, resistent index between male CHD patients and controls; whereas results for weight, total cholesterol, low density lipoprotein cholesterol, triglyceride, VCAM- 1 and IMT of male CHD patients were higher than those of controls; FT level and maximum velocity in systolic phase were lower. It was found that among all the objects, FT level was inversely correlated with IMT and VCAM-1 concentration. Condusion： FT level was inversely correlated with VCAM-I concentration and IMT which are indicators of endothelial function. （Asian JAndro12008 Mar; 10： 214-218）
