Brain structures activated by LPS-urine. a Representative images of c-Fos activation in MeApv, b VMHdm, c LHb, and d PAG (areas delimitated by dashed lines) of cGαi2+/− and cGαi2−/− mice after exposure to LPS-urine. Bottom: higher magnification images of c-Fos+ cells. Scale bars: 50 μm. e Quantification of c-Fos+ cells per μm2 in MeApd, MeApv, VMHdm, VMH, PAG, and LHb of cGαi2+/− and cGαi2−/− mice after exposure to LPS-urine. Statistically significant reduction was observed in the MeApv, VMHdm, PAG, and LHb (n = 8-9 cGαi2+/− and 7 cGαi2−/− mice). No significant differences were observed in the VMH and MeApd (ns, p = 0.33–0.40). Mann-Whitney, *p < 0.05, **p < 0.01. Open circles represent individual mice
