Abstract:
:We recently reported a novel adhesion pathway in lymphocytes that is mediated by cyclin-dependent kinase (Cdk) 4 activity and mediates lymphocyte interactions with endothelial matrix. We now demonstrate that HIV-infected lymphocytes also use Cdk4 to mediate spontaneous adhesion to fibronectin and endothelial matrix. We further demonstrate that HIV-infected lymphocytes require Rap-1 activity for phorbol-stimulated adhesion. Understanding adhesion pathways used by HIV-infected lymphocytes may lead to interventions to regulate aberrant adhesion and migration.
