CTL and serologically defined antigens of B2m,H-3 region.
The antigens of the B2m,H-3 region of 13 chromosome 2 congenic strains and seven inbred strains have been studied by using CML and serologic techniques. Nine patterns of cross-reactivity have been defined by CML assays. These results are in agreement with an extend previously described cross-reactivity studies. The reactivities of three monoclonal antibodies previously thought to be reacting with B2M-B are shown to differ: Ly-m11 and J-5 react with cells of strain B10-pa,at and clone 23 does not. Two H-3 region loci are hypothesized on the basis of CML and serologic activity: B2m and H-3. The CTL responses to the B2M antigens are H-2K restricted; the CTL responses to H-3 antigens are H-2D restricted. The restriction of the response to the H-3 antigen requires effector-target identity of the H-2D molecule but not the B2M molecule of the class I antigen. These loci have been separated by recombination from H-42 in the production of the congenic strain B10.FS-a. A gene order of B2m, H-3, H-42 is suggested.
