Figure 4From: An orally active immune adjuvant prepared from cones of Pinus sylvestris, enhances the proliferative phase of a primary T cell response Serum cytokine levels in mice 48 h post i.p. injection of SEB. Mice were injected i.p. with 100 μg SEB. One group was provided PPC (200 μg/mL) in their drinking water for 48 h (blue bars). Naive mice received an i.p. injection of PBS (red bars). After 48 h serum was obtained and examined by ELISA for the levels of IL-2 (panel A), IFNγ (panel B), and IL-12p70 (panel C). Error bars represent standard deviation.Back to article page
