Mutational escape from CD8+ T cell immunity: HCV evolution, from chimpanzees to man

J Exp Med. 2005 Jun 6;201(11):1709-14. doi: 10.1084/jem.20050808.

Abstract

The mechanisms by which the hepatitis C virus (HCV) establishes persistence are not yet fully understood. Previous chimpanzee and now human studies suggest that mutations within MHC class I-restricted HCV epitopes might contribute to viral escape from cytotoxic T lymphocyte (CTL) responses. However, there are several outstanding questions regarding the role of escape mutations in viral persistence and their fate in the absence of immune selection pressure.
