Abstract:
The relationship between NK cell counts during primary infection and disease progression or immune restoration after antiretroviral treatment (ART) was explored. We followed 462 individuals with HIV infection and measured their NK, CD4+ T, CD8+ T cell counts and viral loads. Our data showed that individuals with high NK cell counts had much lower viral loads and higher CD4+ T cell counts. NK cell counts during primary infection were negatively correlated with viral set-point and viral loads at one-year-infection point, and positively correlated with CD4+ T cell counts at one-year-infection and one-year-ART point. Moreover, the NK cell counts during primary infection can predict HIV disease progression and immune restoration after ART. In conclusion, NK cell counts during primary infection represents a potential predictive biomarker to predict HIV disease prognosis in the clinic.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
