Figure 1. The effects of prior neonatal activity on selected circulating cytokines at post-partum day 30.

Figure 1

Rat neonates experienced increased physical activity (EX), handling (HAND) or no treatment (CON) from post-partum day 5 through 15. A subgroup was sampled at day 30. The neonatal activity treatment resulted in lower circulating levels of TNFα and higher IL-6 in 30 day males. Plasma levels of IL-1β were elevated in HAND rats relative to CON and EX. n = 8; *, P<0.05 vs. CON; ‡, P<0.05 vs. HAND.
