Abstract:
We aimed to clarify the role of liver-infiltrating FoxP3(+) T cells for the response to therapy in chronic hepatitis C. Liver biopsies from 52 patients were collected prior to the start of interferon/ribavirin treatment, and the kinetics of viral decay during treatment were compared in patients with high and low infiltration of FoxP3(+) cells. These groups did not differ with respect to the effectiveness of early viral clearance or the frequency of sustained viral response. Our data imply that FoxP3(+) cell-mediated immunosuppression is not a major mechanism of hyporesponsiveness to interferon-based therapy in chronic hepatitis C.

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...
