The major histocompatibility complex of the rat

Abstract

Immunogenetic studies in the rat began with the investigation of blood group antigens (1-7) and evolved into the investigation of histocompatibility antigens and transplantation phenomena (8-17). In the course of this work, several nomenclature systems evolved that were eventually reconciled in a series of comparison studies (18-24). The biennial Workshops on Alloantigenic Systems in the Rat held under the aegis of the Transplantation Society (24) have provided the forum for the continued evolution of this field. In addition, several reviews (24-31) and books (32-35) have provided periodic summaries of different aspects of rat immunogenetics. This review will focus on the structure of the major histocompatibility complex (MHC) of the rat from the serological, biochemical, and molecular points of view.
