In vitro proliferation and production of cytokines by spleen cells from BALB/c nude mice; some of the mice had received P. berghei-specific T cells and/or were challenged with live pRBCs at day 0. Spleen cells were taken at days 7, 10, and 14 from mice that had received the following treatments. Bars: A, received 10⁷ specific T cells but were not infected; B, received 10⁷ T cells and were infected with 10⁶ pRBCs; C, were infected but not given specific T cells; D, were neither infected nor given specific T cells. Cells were investigated for lymphoproliferation in response to Con A or pRBC lysate and for cytokine production in response to pRBC lysate. The data show the mean ± 1 SEM.
