title: Deficiency in suppressor T cell activity in aged animals. Reconstitution of this activity by interleukin 2.
abstract: Spleen cells derived from aged (30 mo) C57Bl/6 mice are shown to be deficient in the ability to generate suppressor cell activity in vitro. The addition of IL-2 to cultures containing aged cells restores this function to a large extent.
