Extended Data Fig. 5. PPGNTS neurons are necessary for oxytocin-induced eating suppression.

(a-b) Food intake and bodyweight change over 1 day in eGFP and DTA mice (n=5 (DTA) / 7 (eGFP) animals) administered oxytocin (0.4 mg/kg, i.p.), 2-way mixed-model ANOVA: a) Drug F(1,10)=0.00474, p=0.947; b) Drug F(1,10)=0.0989, p=0.760.
(c-d) Photomicrographs of coronal NTS sections from PPG-Cre:GCaMP3 mice injected with eGFP control virus (c) or DTA virus (d). Note the complete absence of green (GCaMP3-expressing, amplified by immunostaining against the GFP antigen) PPGNTS neurons in DTA-ablated tissue, and the extent of viral spread as demonstrated by constitutive expression of mCherry (photomicrographs representative of independent experiments from 7/5 animals). Distance in mm posterior to Bregma in bottom left, cc: central canal. Scale=100μm.
All data presented as mean ± SEM.
