[Advances in major histocompatibility complex research in poultry]

As the development of poultry genome project, it has been acquired many advances in the study of poultry MHC. At present, we have achieved some MHC sequences, locations of MHC on chromosome and some MHC gene functions. This article give a detailed introduction about gene structure of poultry MHC and its role in immune reaction, relation with antibody and advances in poultry genome about MHC. With the development of related research, how to use the result of the study more efficiently become more and more important to the poultry MHC study.
