Acute Neuroinflammatory Response in the Substantia Nigra Pars Compacta of Rats after a Local Injection of Lipopolysaccharide

Figure 7

Levels of cytokines in the substantia nigra after LPS local injection. qPCR (a–e) and ELISA (f–j) were used to measure mRNA and protein levels, respectively, for TNF-α, IL-1β, and IL-6 (proinflammatory cytokines) and IL-4 and IL-10 (anti-inflammatory cytokines). Ut = untreated control rats. Mock = rats injected with the vehicle (2 μL of endotoxin-free physiological saline solution) in the left substantia nigra. All values represent the mean ± SD ( independent rats in each time of each experimental condition). or when compared with the untreated control group. when compared with the respective mock group. Repeated-measures one-way ANOVA and Newman-Keuls post hoc test for ELISA and repeated-measures two-way ANOVA and Bonferroni post hoc test for the qPCR assay.
