Greenspan %J Archive of "Pathogens and Immunity". %D 2018 %R 10.20411/pai.v3i2.260 %X In 1974, Peter Doherty and Rolf Zinkernagel published a landmark article in Nature [1] that described the ability of lymphocytic choriomeningitis virus (LCMV)-specific cytotoxic T cells to lyse LCMV-infected, 51Cr-labeled target cells if the target cells shared class I major histocompatibility complex (MHC) molecules with these T cells. Surprisingly, infected and labeled target cells with disparate class I MHC molecules were not lysed. This phenomenon, which came to be known as ¡°MHC restriction,¡± was a major advance in our understanding of the way in which T cells recognize antigen and was ultimately the basis for the awarding of the 1996 Nobel Prize in Physiology or Medicine to Peter Doherty and Rolf Zinkernagel.
