Toxoplasma antigen-specific T cell proliferation in cells from T. gondii-infected animals. (a) 1.5 × 10⁵ PBMC/well from 6 pigs before infection and 7 dpi were stimulated in triplicate with TLA or ConA for 4 days. Thereafter, ³H-thymidine was added for 18–24 h. Data are given as mean cpm ± SD from 6 individuals. (b) TLA-specific cell proliferation from uninfected and infected (28 dpi) animals. Each dot represents the result of one individual. Significant differences are marked with asterisks. Data are given as mean cpm ± SD from 5 individuals; (n.s. = not significant; ^∗∗∗p ≤ 0.0001).
