Cell Biology of the Major Histocompatibility Complex

Cell Biology of the Major Histocompatibility Complex documents the proceedings of a symposium on ""Cell Biology of the Major Histocompatibility Complex"" held at Arden House on the Harriman Campus of Columbia University from June 8 -10, 1984. The meeting was the ninth of the P & S Biomedical Sciences Symposia. The book is organized into five parts. Part I on the structure of MHC molecules includes papers on human histocompatibility antigens; the cloning of human MHC; and organization of the genes of the H-2 complex. Part II on alternate forms of MHC molecules includes studies on the expression of a secreted form of the MHC class I antigen and alternative splicing in the H-2 multigene family. Part III deals with MHC biosynthesis, intracellular transport, and membrane expression. It includes studies on the manipulation of glycans on antigens of the MHC and dynamics of MHC molecules in lymphoid cells. Part IV on homologues of class I MHC molecules covers topics such as Tla expression in normal and malignant cells and the Qa series of antigens. Part V on the association of MHC with antigens includes studies such as histocompatibility molecules as immune response gene products and molecular nature of T-cell recognition of antigen.
