The Drosophila G protein-coupled receptor, GulpR, is essential for lipid mobilization in response to nutrient-limitation

Daniela Barraza, Xiang Ding, Lauren Findley…·Paula I. Watnick

This paper identifies GulpR, a Drosophila GPCR expressed in enteroendocrine cells, and shows it regulates Tachykinin transcription, essential for lipid mobilization during nutrient limitation but not infection.

A conserved, immune-regulated peritrophin promotes Vibrio cholerae colonization of the arthropod intestine

Daniela Barraza, Tânia F. Paulo, Lauren Findley…·Paula I. Watnick

The paper identifies Peri-15a, a chitin-binding protein upregulated by immune activation in enteroendocrine cells, as essential for Vibrio cholerae colonization of arthropod intestines.
