Abstract The role of IgD (δ) in the induction of tolerance in murine B lymphocytes was explored in the in vivo adoptive antibody response to bovine serum albumin (BSA). δ + or δ − B cells purified on the fluorescence‐activated cell sorter were injected, with or without purified T cells, into lethally irradiated intermediate hosts, which were rendered tolerant by an injection of deaggregated BSA one day after the cell transfer. Spleen cells from the intermediate hosts were treated with anti‐Thy‐1.2 antiserum and complement mixed with normal T cells and were transferred to final hosts. The ability of the B cells of the final hosts to respond to the tolerogen BSA and to dinitrophenylated human gamma globulin antigen was examined. This approach enabled examination of the function of the B cell subpopulations in an environment free of tolerogen and of induced T suppressor cells. The results revealed that in the presence of T cells the δ + subpopulation was highly resistant to tolerance induction, whereas the δ − subpopulation was highly susceptible to tolerance induction. However, there was no difference in susceptibility to tolerance induction between the two subpopulations when tolerance was induced in the absence of T cells.
