Brain cytokines levels long term after episodic inflammation. Brain cytokines IL-1ß (a), IL-6 (b), IL-4 (c), and IL-10 (d) were measured in young and aged mice naïve (control) and after episodic systemic inflammation (SI). All cytokines measured were significantly elevated in the brains of aged mice after SI. Data were plotted as means ± SEM (N = 8 per group, samples collected from 3 independent experiments). Statistical analysis with two-way ANOVA with Bonferroni posttest (*P < 0.05, **P < 0.01, ***P < 0.001)
