Virus subversion of protective immunity.
The major histocompatibility (MHC) class I antigen presentation pathway plays a pivotal role in immunity to viruses. MHC class I molecules are expressed on the cell surface of all nucleated cells and present peptides derived from intracellular proteins to cytotoxic T lymphocytes (CTLs), which then eliminate virally infected cells. However, many viruses have evolved proteins to inhibit the MHC class I pathway, thus enabling virally infected cells to escape CTL lysis. In this review, we summarize recent findings about viral inhibition of the MHC class I pathway.
