Genetic control of the antibody response to type III pneumococcal polysaccharide in mice. III. Analysis of genes governing the expression of regulatory T cell activity.

Recombinant-inbred strains of mice, as well as the progenitor strains from which they were derived, were evaluated with respect to the capacity of B cells to respond to an optimally immunogenic dose of Type III pneumococcal polysaccharide (SSS-III) and the amount of suppressor and amplifier T cell activity present. None of these functional activities was found to be linked to genes within the major histocompatibility (H-2) or the IgCH allotype complex, and several autosomal genes appeared to govern the expression of each of these characteristics.
