Fig. 1. Serum TNF- concentrations for interleukin-2 deficient (IL-2^-/-) (n = 6) and wild-type control (IL-2^+/+) (n = 6) male mice in the fed state and after 24 hours of starving at 10 weeks of age. Values are the means ± SEM. Means in the same nutritional state (fed, starved) and between nutritional states with a different letter differ, p < 0.05 (ANOVA and subsequent Fisher’s protected least significant difference test).
