IL-15 restores CD56 on CD8 T cells from HIV infected patients.

<p>(A) Most CD8 T cells and almost all CD56 + CD8 T cells express the common gamma chain (γ_c) (or CD132). Representative plots (from left ND, PD, NVS, VIR) show there was no significant downregulation of this receptor on CD8 T lymphocytes from any infected group (B) Culture of PMBC in IL-15 resulted in a significant upregulation of CD56 on CD8 T lymphocytes at day 12 relative to start of culture in infected and uninfected samples.
