Escape mutations alter proteasome processing of major histocompatibility complex class I-restricted epitopes in persistent hepatitis C virus infection.

Abstract excerpt

Mutations in hepatitis C virus (HCV) genomes facilitate escape from virus-specific CD8+ T lymphocytes in persistently infected chimpanzees. Our previous studies demonstrated that many of the amino acid substitutions in HCV epitopes prevented T-cell receptor recognition or binding to class I major histocompatibility complex molecules. Here we report that mutations within HCV epitopes also cause their destruction...
