A potential weak allelic difference in male-specific antigen between two inbred strains of mice.
Differences were detected between male-specific antigen(s) from BALB/c and C57BL/10 mice. Reciprocal crosses between these strains were analysed by means of a popliteal lymph node assay enumerating cells secreting IgM and IgG in a T-dependent bystander B-cell response. The responses, while being indirect, weak and variable, suggested that there are differences in 'immunogenicity' coded by Y-linked (male-specific) genes. This conclusion was strengthened by the results of experiments carried out in Y-backcross mice, where spleen cells from male C57BL mice with a BALB/c-Y (B10.C-YC) stimulated low popliteal lymph node responses in female littermates in comparison with C57BL mice with their own Y-chromosome. In contradistinction, male spleen cells from a BALB/c with a C57B1/10-Y chromosome (C.B10-YB), injected into a hind footpad of a female littermate, induced a relatively higher popliteal lymph node response.
