Fig. 5From: Arcuate AgRP, but not POMC neurons, modulate paraventricular CRF synthesis and release in response to fastingInhibition of AgRPARC neurons in fasted animals reduces CRF content in the PVN and increases its accumulation in the median eminence: Representative photomicrographs (D and E) and quantitative CRF-IR (green) cell number (A) and mean intensity (B and C) in both PVN and median eminence of Agrp-IRES-Cre animals that received intra ARC injection of AAV-DIO-mCherry or AAV-DIO-hM4D(Gi)-mCherry (red) submitted to 36 h of fasting and treated 5 i.p. injections CNO (1 mg/kg). Tissue samples obtained from experimental procedure described in the Fig. 3 were used for CRF immunostaining studies. The cell nuclei were staining with Hoechst (blue). Data are expressed as mean ± SEM and were analyzed by unpaired t test: *p < 0.05 vs Agrp-IRES-Cre:: AAV-DIO-mCherry fasted and treated with CNOBack to article page
