FIG. 3.

Inhibition of Th1 and Th2 effector cytokines by L. paracasei NCC2461 in MLR. CD4⁺ T cells were primed in medium alone (−) or in the presence of L. paracasei NCC2461 (10⁷ or 10⁶ CFU/ml), LPS (1 μg/ml), or a blocking anti-IL-4 MAb (1D11; 10 μg/ml). Cytokine levels were measured 48 h after the third stimulation. Error bars indicate the SEM of triplicate cultures.
