IL 15 generates a dramatic expansion of short-lived memory CD8 T cells and natural killer in immunocompetent macaques and has long-term effects on the balance of CD4(+) and CD8(+) T cells. PMID: 20631381
These data suggest that therapeutic use of IL-15 in the setting of antiretroviral therapy might facilitate specific restoration of the CD4 + T cell compartment. PMID: 16691294
IL-15 secretion significantly correlates with the up-regulated expression of CD4 on memory CD4 T cells that is associated with increased permissiveness to simian immunodeficiency virus infection. PMID: 19155491
