α4 Integrin Binding Interfaces on VCAM-1 and MAdCAM-1

The Effects of Resistance Training on VCAM-1, ICAM-1 and CRP in Diabetic Rats

Objective: Many diabetic patients are susceptible to cardiovascular diseases which are known as one of the most important causes of mortality among diabetic patients. The aim of this study was to investigate the effects of eight weeks of resistance training on VCAM-1, ICAM-1 and CRP in diabetic rats. Materials and Methods: In this experimental study, 24 male Sprague- Dawley diabetic rats were ...

Contrasting roles for domain 4 of VCAM-1 in the regulation of cell adhesion and soluble VCAM-1 binding to integrin alpha4beta1.

Cell adhesion mediated by the interaction between integrin alpha4beta1 and VCAM-1 is important in normal physiologic processes and in inflammatory and autoimmune disease. Numerous studies have mapped the alpha4beta1 binding sites in VCAM-1 that mediate cell adhesion; however, little is known about the regions in VCAM-1 important for regulating soluble binding. In the present study, we demonstra...

Contrasting Roles for Domain 4 of VCAM-1 in the Regulation of Cell Adhesion and Soluble VCAM-1 Binding to Integrin

VCAM-1 is more effective than MAdCAM-1 in supporting eosinophil rolling under conditions of shear flow.

The ability of the alpha4 integrin counterligands vascular cell adhesion molecule (VCAM)-1 or mucosal addressin (MAd)CAM-1 to support eosinophil rolling or firm adhesion under conditions of physiologic flow has not been delineated. Using a parallel plate flow chamber in vitro and intravital microscopy in vivo, we demonstrate that eosinophil rolling and adhesion on VCAM-1 is mediated by both alp...

Polymorphisms in the α4 Integrin of Neotropical Primates: Insights for Binding of Natural Ligands and HIV-1 gp120 to the Human α4β7

The α4 integrin subunit associates with β7 and β1 and plays important roles in immune function and cell trafficking. The gut-homing receptor α4β7 has been recently described as a new receptor for HIV. Here, we describe polymorphisms of ITGA4 gene in New World primates (NWP), and tested their impact on the binding to monoclonal antibodies, natural ligands (MAdCAM and VCAM), and several gp120 HIV...
