Figure 6. Effect of S14 on in vivo inflammation and rotational behavior.
Lipopolysaccharide (LPS, 10 µg) or vehicle was injected unilaterally into the adult substantia nigra pars compacta (SNpc) of adult rats. A group of animals also received S14 (20 nmol) or BRL50481 (BRL, 60 nmol) together with LPS. (A) After 72 h the brains were removed and tissue sections were processed for CD11b (OX-42) immunoreactivity lo label activated microglia. Scale bars, 500 µm. Insets scale bars, 100 µm. Quantification of the reactive cells is expressed as the mean ± SD, from three different experiments, four animals/experiment/experimental group, and five independent sections per animal. ***p<0.001 versus LPS-treated animals. (B) Behavioral analysis. Three weeks after treatment apomorphine-induced rotations were analyzed in control, LPS-injected, and LPS+S14-injected rats. Values represent the means ± SD from three different experiments. ***p<0.001, versus LPS-injected animals.
