Two classes of major histocompatibility complex (MHC) molecules, MHC class I and class II, play important roles in our immune system, presenting antigens to functionally distinct T lymphocyte populations. However, the origin of this essential MHC ...

A unique new nonclassical MHC class I lineage was found in Teleostei (teleosts, modern bony fish, e.g., zebrafish) and Holostei (a group of primitive bony fish, e.g., spotted gar), which was designated “H” (from “hexa”) for being the sixth lineage...

Background
MHC class I (MHCI) molecules are the key presenters of peptides generated through the intracellular pathway to CD8-positive T-cells. In fish, MHCI genes were first identified in the early 1990's, but we still know little about their fun...

The major histocompatibility complex (MHC) class I-related molecule, MR1, is highly conserved in mammals and can present bacteria-derived vitamin B metabolites to mucosal-associated invariant T (MAIT) cells, possibly having important defense funct...

The major histocompatibility complex (MHC) class I-related gene, MR1, is a non-classical MHC class IA gene and is encoded outside the MHC region. The MR1 is responsible for activation of mucosal-associated invariant T (MAIT) cells expressing semi-...
