Asthma is a chronic inflammatory disease induced by Type 2 helper T cells and eosinophils. Vascular cell adhesion molecule-1 (VCAM-1) has been implicated in recruiting eosinophils and lymphocytes to pathological sites in asthma as a regulatory receptor. Accordingly, monoclonal antibody (mAb) against VCAM-1 may attenuate allergic inflammation and pathophysiological features of asthma. We attempt...

Objective: To examine the effects of Trichosanthes kirilowii Maximowicz extract (TE) and Maxi mowicz Cheonghyeol Plus Phellinus linteus plus (TCP) on anti-inflammatory factor expression in human umbilical vein endothelial cells (HUVECs).Methods: HUVECs were activated with TNF-α then treated TE TCP. The levels measured for intracellular genes (KLF2, eNOS, MCP-1, ICAM-1, VCAM-1), proteins VCAM-1,...

We investigated the effects of mixed leukocyte reaction (MLR), hydrocortisone (HC) and cyclosporine A (CsA) on the expression of leukocyte adhesion molecules on the mesangial (MC) and endothelial cells (EnC). Cell surface enzyme immunoassay showed that INFnu, IL-1beta, or TNF alpha stimulated expression of ICAM-1, or VCAM-1 on MC after 24 hours. Flow cytometric analysis demonstrated that MLR su...

Immune escape is an important reason why the immune system cannot control tumor growth, but how escape variants emerge during immunotherapy remains poorly understood. Here, we identify a new mechanism of tumor immune escape using an in vivo selection strategy. We generated a highly immune-resistant cancer cell line (P3) by subjecting a susceptible cancer cell line (P0/TC-1) to multiple rounds o...

Endothelial attachment is the initial step in leukocyte recruitment into developing atherosclerotic lesions. To determine whether vascular cell adhesion molecule-1 (VCAM-1) expression may play a role in inflammatory cell recruitment into human atherosclerotic lesions, immunohistochemistry was performed with a polyclonal rabbit antisera, raised against recombinant human VCAM-1, on 24 atheroscler...

Resident bone marrow macrophages provide a microenvironment for erythropoiesis, forming erythroblastic islands (EBIs) via adhesion molecules. In this study, we examined vascular cell adhesion molecule-1 (VCAM-1) expression in human bone marrow specimens using immunohistochemistry. VCAM-1 was strongly expressed in CD169 macrophages in EBIs and weakly in sinusoidal vascular endothelial cells. In ...

is an immunoglobulin-like adhesion molecule expressed on activated endothelial cells (1). VCAM-1 binds to α 4 β 1 integrin, which is consti-tutively expressed on lymphocytes, monocytes, and eosinophils. Interestingly , VCAM-1 can mediate both rolling-type adhesion and firm adhesion , depending on the avidity status of α 4 β 1 integrin (2). Although it is structurally similar to ICAM-1 and other...

Interaction between vascular cell adhesion molecule-1 (VCAM-1) on endothelial cells and alpha 4 integrins on leukocytes is thought to mediate the selective recruitment of eosinophils and lymphocytes that occurs in allergic diseases. IL-4 is associated with allergic conditions, and it has been shown to selectively increase expression of VCAM-1 on endothelial cells in vivo, suggesting that it cou...

The expression of vascular adhesion molecule-1 (VCAM-1) by endothelial cells may play a major role in atherogenesis. The actual mechanisms of chlamydia pneumoniae (C. pneumoniae) relate to atherogenesis are unclear. We investigate the influence of VCAM-1 expression in the GroEL1 from C. pneumoniae-administered human coronary artery endothelial cells (HCAECs) and hypercholesterolemic rabbits. In...
