Hapten-specific, trinitrophenyl antigen-binding B cells (TNP-ABC) were purified from inbred strains of mice representative of short-, intermediate-, and long-lived animals. Such populations of B cells were stimulated by either thymus-independent or thymus-dependent antigens in vitro and evaluated for both proliferation and differentiation into antibody-secreting cells. In the thymus-dependent system, the three strains of mice were selected on the basis of all being able to interact appropriately with the same T helper cell line. The results indicate that TNP-ABC purified from aged animals of all three strains responded to both forms of antigenic stimulation similar to TNP-ABC selected from young, littermate control animals. These results are discussed in terms of concepts of intrinsic B cell defects during the aging process.
