Figure 5. Brain cytokine levels.

Figure 5.

Aged controls (Aged CON) had higher levels of IL-6 relative to young controls (Young CON) and aged mice in the exercise groups (A). Brain levels of IL-1β were elevated in the aged short-term exercise (Aged ST Ex) mice relative to young controls and aged long-term exercise (Aged LT Ex) mice (B). There was no difference in IL-10 levels between the groups (C). Box plots show median protein levels and the 25th and 75th quartiles with the 5th and 95th percentile shown by the whiskers. Dots represent individual data points within groups. Symbols indicate a significant difference from young control (*), aged control (^), or aged short-term exercise (+).
