α4β1 integrin-dependent cell sorting dictates T-cell recruitment in oral submucous fibrosis

The biological mechanism(s) that guide the immunological effectors of lymphocytes to sites of inflammatory response, a feature consistently seen in oral submucous fibrosis (OSF) was evaluated. It is envisaged that endothelial/lymphocyte adhesion cascades involving VCAM-1/α4β1 integrins control the migration of lymphocytes across the vascular endothelium resulting in their homing in these locales.
