Very excited to share this finding from my postdoctoral work that is now published in #ScienceAdvances. We show how the gut’s epithelium modifies enteric behaviors during nutritional adversity via distinct peptidergic signaling axes. www.science.org/doi/10.1126/... Thread ⬇️ (1/n)

Gut epithelium modifies enteric behaviors during nutritional adversity via distinct peptidergic signaling axes
Gut epithelium modulates output from distinct enteric circuits by altering secretion of insulin and noninsulin peptides.
