Age-related changes, including synergy and suppression, in the mixed lymphocyte reaction in long-lived mice
Fed Proc.
1975 Feb.
Abstract
The mixed lymphocyte culture reaction represents the in vitro counterpart of the recognition phase of the graft-versus-host reaction, and of allograft rejection. The mixed lymphocyte culture reactivities of lymph node and spleen cells from all strains show a striking decline with advanced age. Furthermore, studies of "synergy" between subpopulations of T cells in the mixed lymphocyte culture reaction suggest that the cells of the recirculating lymphoid pool (T2 cells) in particular display a functional decline. Finally, spleen cells from old mice of appropriate strains inhibit or suppress the mixed lymphocyte culture reactivity of lymph node or spleen cells from young mice.
