Effect of alcoholic ginger extract on IL-2 (A) and IFN-γ (B) production by T cells in presence of alloantigen stimulation. Peritoneal macrophages were incubated with LPS in the presence or absence of ginger extract for 24 h. These pre-treated macrophages were used as the sole source of APCs along with syngeneic T cells as the responder cells in the presence of allostimulation. IL-2 and IFN-γ production was measured in the culture supernates after 72 h. incubation period. * p ≤ 0.05 in comparison to Control. # p ≤ 0.05 in comparison to LPS.
