Matrix fibronectin increases HIV stability and infectivity.

Abstract

HIV particles are detected extracellularly in lymphoid tissues, a major reservoir of the virus. We previously reported that a polymerized form of fibronectin (FN), superfibronectin (sFN), as well as a fragment of FN, III1-C, enhanced infection of primary CD4(+) T cells by HIV-1IIIB. We now show that sFN enhances infection of primary CD4(+) T cells by both… (More)
