Randomized trial examines interferon-alpha impact on antiviral response in chimpanzees, suggesting tissue-specific effects on hepatitis C treatment.

This study aims to investigate the antiviral response of interferon-alpha in chimpanzees to understand its role in hepatitis C treatment.
Examined transcriptional response to IFN-alpha in uninfected chimpanzees after doses of chimpanzee, human, or human-pegylated IFN-alpha.
Conducted total genome microarray analysis on liver and peripheral blood mononuclear cell samples.
Assessed gene expression changes over time post-inoculation at various time points after treatment.
1778 genes were altered in expression by IFN-alpha, with 538 and 950 showing unique responses in liver and PBMC, respectively.
Most induced genes peaked at 4 hours post-IFN-alpha treatment and returned to baseline levels by 24 hours, despite ongoing IFN-alpha presence.
Rapid downregulation of the IFN-alpha response may significantly influence antiviral kinetics during hepatitis C treatment.

Lanford et al. (2006) studied this question.
