HLA class I and II antigens
The human leukocyte antigens (HLA) have been defined by serological methods. There exist two kinds of receptor classes for major histocompatibility complexes (MHC): MHC class I and MHC class II. The class I antigens are HLA-A, HLA-B, and HLA-C and the class II are HLA-DR-, HLA-DQ, and HLA-DP. By determining HLA type an assessment of histocompatbility is made. It is thought that HLA-A, HLA-B and HLA-DR are the most
Which one of the following interactions between surface molecules must take place for a T-cytotoxic cell to be stimulated to begin to destroy a virus-infected cell? (assume that the antigen and the receptor are also interacting correctly)
