abstract = {HIV infection is associated with impaired NK cell activity,
which is only incompletely restored under antiretroviral
therapy. Analysing the bioenergetics profiles of oxygen
consumption, we observed several parameters were
significantly reduced in HIV(+) NK cells, indicating a
mitochondrial defect. Accordingly, we found HIV(+) CD56
bright NK cells to display a decreased mitochondrial
membrane potential and mitochondrial mass. Both parameters
were positively correlated with IFNγ production of NK
cells. Finally, we demonstrated that stimulation of HIV(+)
NK cells with MitoTEMPO, mitochondria-targeting antioxidant,
significantly improved IFNγ production. In conclusion, we
identified mitochondrial dysfunction as a mechanism that
contributes to impaired NK cell function.},
