Hierarchy of multiple viral CD8+ T-cell epitope mutations in sequential selection in simian immunodeficiency infection.

Abstract excerpt

CD8+ T-cell responses exert strong suppressive pressure on viral replication and select for viral escape mutations in HIV infection. Multiple viral epitopes restricted by major histocompatibility complex class I (MHC-I) are targeted by CD8+ T cells. Sequential selection of viral escape mutations in individual epitope-coding regions could result in failure in CD8+ T cell-based viral control leading to disease...
