FIG. 2.

Inhibition of CD4⁺ T-cell proliferation by L. paracasei NCC2461. 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 MAb against IL-4 (1D11; 10 μg/ml). Proliferation was measured 48 h after the third stimulation. Error bars indicate the SEM of triplicate cultures.
