title: Presentation of antigenic peptides by MHC class I molecules.
abstract: The basis for the immune response against intracellular pathogens is the recognition by cytotoxic T lymphocytes of antigenic peptides derived from cytosolic proteins, which are presented on the cell surface by major histocompatibility complex (MHC) class I molecules. The understanding of MHC class I-restricted peptide presentation has recently improved dramatically with the elucidation of the structural basis for the specificity of peptide binding to MHC class I molecules and the identification of proteins encoded in the class II region of the MHC that are putatively involved in the production of peptides and their transport into the endoplasmic reticulum, where they assemble with class I molecules.
