title: Interleukin 16: implications for CD4 functions and HIV-1 progression.
abstract: In this article, David Center and colleagues clarify the controversies that have emerged over the unique structure of interleukin 16 and its anti-HIV-1 activity. Interleukin 16 is a ligand for CD4, and this implies CD4 acts as a sentinel receptor that can switch CD4+ T cells between immune and inflammatory functions.
