Altered T-cell subsets in HIV-1 natural viral suppressors (elite controllers) with hepatitis C infection
Abstract:
We have established a cohort of 64 Natural Viral Suppressors (NVS) (similar to Elite Controllers/Elite Suppressors), 30 of which have chronic hepatitis C virus (HCV). We investigated T-cell phenotypic changes in association with HCV infection. NVS without HCV and normal controls had similar T-cell phenotypes. However, NVS with HCV had lower naive cell proportions (CD4 and CD8) compared with NVS without HCV (P = 0.0008 and P = 0.02) or normal controls (P = 0.0163 and P = 0.017). These results and previously reported data suggest that HCV coinfection increases immune activation and T-cell disturbances. Any associated T-cell functional changes or potential clinical consequences need further study.

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...
