  • Title: Spleen cells from adult mice given total lymphoid irradiation (TLI) or from newborn mice have similar regulatory effects in the mixed leukocyte reaction (MLR). II. Generation of antigen-specific suppressor cells in the MLR after the addition of spleen cells from newborn mice.

    Abstract:
    Spleen cells from newborn BALB/c mice were added to the mixed leukocyte reaction (MLR) between a variety of responder and stimulator cells. The newborn cells nonspecifically suppressed the uptake of (3H)-thymidine and the generation of cytolytic cells regardless of the responder-stimulator combination used. Suppressor cell activity fell rapidly during the first 4 days after birth, and could not be detected by day 20. Newborn spleen cells inhibited the generation of nonspecific suppressor cells during the MLR but did not inhibit the generation of antigen-specific suppressor cells. Thus, newborn spleen cells exhibit a pattern of regulation of the MLR similar to that reported previously for spleen cells from adult mice given total lymphoid irradiation (TLI). These regulatory interactions provide a model that explains the ease of induction of transplantation tolerance in vivo in newborn mice and in TLI-treated adult mice.
