Delayed Induction, Not Impaired Recruitment, of Specific CD8+ T Cells Causes the Late Onset of Acute Hepatitis C

Chemokines are induced during early stages of HCV infection, which requires a type I IFN-mediated response. The delayed onset of acute hepatitis does not result from delayed recruitment of HCV-specific T cells, but could instead be related to a primary delay in the induction of HCV-specific T cells. Divergent outcomes occur without evident differences in chemokine induction and T-cell recruitment.
