Figure 2. Thoracic lymph nodes cells suppressive activity.

TLN cells (2.5×10⁵) from naïve (N), non sensitized T. gondii infected (T) and infected/sensitized (TO) mice were in vitro co-cultured with thoracic lymph nodes cells (2.5×10⁵) from allergic (O) mice. Proliferative responses were determined by ³H-thymidine incorporation after a 5-day culture period upon OVA stimulation. Results are expressed as an Index (incorporation by cells stimulated over those cultured with medium alone). * p<0.01 TO vs N; ANOVA with Bonferroni a posteriori.
