While the prime function of classical MHC class I molecules (MHC-I) is to present peptide antigens to pathogen-specific cytotoxic T cells, non-classical MHC-I antigens perform a diverse array of functions in both innate and adaptive immunity. In this review we summarize recent evidence that non classical MHC-I molecules are not only recognized by pathogen-specific T cells but that they also serve as immunoregulatory molecules by stimulating a number of distinct non-conventional T cell subsets.
