Discovery of MHC restriction in antigen recognition of T cells / 中国医学科学院学报

ABSTRACT

T cell can only recognize specific antigenic peptide-MHC complex on antigen-presenting cell. This is MHC restriction in antigen recognition of T cell. This phenomenon was discovered by an Austrian scientist Peter. C. Doherty and a Swedish scientist Rolf. M. Zinkernagel by chance. Then, in order to explain the phenomenon, they proposed two hypotheses: dual receptor and modified self. In the during following 20 years numbers of scientists spent great amount of time in the study of the phenomenon. The process of cell-mediated immune response becomes clear, which greatly promotes the advancing of immunology and many related disciplines.
