In the present study, we performed DNA microarray analyses and phenotypic and functional analyses in an effort to elucidate the mechanisms by which ongoing HIV replication affects the physiologic function of natural killer (NK) cells. Functional assays confirmed an increased propensity of NK cells from HIV-infected viremic individuals to undergo Fas-mediated apoptosis but not CD16- or NKG2D-mediated apoptosis. Serum levels of sFasL and expression of Ki67 on NK cells were markedly elevated in HIV-infected viremic individuals when compared with those of HIV-infected aviremic and HIV-seronegative individuals. Our data demonstrate that ongoing HIV replication results in profound NK-cell abnormalities that are likely to be attributable to the effects of virus-induced immune activation. Of note is an increased susceptibility to cell death mediated by CD95-sFasL interactions. In addition, these NK cells, particularly the CD56dim CD16bright subset, undergo enhanced cell turnover in vivo, as demonstrated by intracellular Ki67 expression.
