Webinhibits CD95/Fas-induced apoptosis of the effector-memory CD4+ and CD8+ T cells from HIV-infected individuals. These ﬁndings suggest that in addition to being a growth and survival factor for memory CD8+ T cells, IL-15 is also a potent activator of human effector-memory CD8+ T cells both in healthy and in HIV-infected individuals. Introduction WebFas death receptor (also named CD95 or APO-1) is physiologically activated through binding to its cognate ligand, FasL. Fas/FasL interaction induces oligomerization and aggregation of Fas receptor, leading eventually to …
