Figure 2.

Mitogenic responses to Con A and LPS in spleen (left panels) and SmLN (right panels) of control and calorie-restricted rats. Data shown as mean ± SEM (n = 7 rats/group). Letters indicate the existence of significant differences between groups after a one-way ANOVA followed by a Bonferroni's test, as follows: ^a p < 0.02 vs. control rats not injected with SCH; ^b p < 0.03 vs. 66% calorie-restricted rats.
