摘要

1. Non-human animal containing on the endogenous locus of the main histocompatibility complex I (MHC I) a nucleotide sequence encoding a chimeric human / non-human MHC I polypeptide, the human part of the chimeric polypeptide containing the extracellular domain of the human MHC I polypeptide, and not a human animal expresses a chimeric human / non-human MHC I.2 polypeptide. The non-human animal according to claim 1, wherein the animal is a rodent, wherein the rodent contains at the endogenous locus of the main histocompatibility complex I (MHC I) a nucleotide sequence encoding a chimeric human / rodent-related MHC I polypeptide I, wherein the human portion of the chimeric polypeptide contains the extracellular domain of the human MHC I polypeptide, and the rodent expresses the chimeric human / rodent-related MHC I.3 polypeptide. The rodent according to claim 2, wherein the rodent does not express the extracellular domain of the rodent endogenous MHC I polypeptide from the endogenous rodent MHC I locus. A rodent according to claim 2, in which the nucleotide sequence is functionally linked to the endogenous regulatory elements of the rodent. The rodent according to claim 2, wherein the rodent is a mouse. A mouse according to claim 5, wherein the endogenous locus is the mouse N-2K locus. A rodent according to claim 2, wherein the human portion of the chimeric polypeptide contains a human leader sequence. A rodent according to claim 2, in which the human part of the chimeric polypeptide contains the α1, α2 and α3 domains of the human MHC I polypeptide. Rodent according to claim 2, in which the part x related to the rodent
