An islet-resident macrophage antioxidant program preserves β cell physiology SLC7A11 licenses metabolic and antioxidant activities in islet macrophages, supporting β cell insulin secretion and redox homeostasis.

A new #ScienceImmunology study finds that mice and humans have pancreatic islet-resident macrophages with elevated antioxidant profiles, which could shield β cells from oxidative stress. https://scim.ag/49cqs3M

Very excited to share that our paper on pancreatic islet-resident macrophages is out ! Grateful to contribute to our understanding of these fascinating cells - special thanks to all of our collaborators ! #worlddiabetesday www.science.org/doi/10.1126/...

Schematic of the competitive catabolism model

Excited to share my latest postdoc work on systemic metabolic homeostasis! We show that nutrient consumption fluxes compete, and this competitive catabolism helps explain why obesity drives diabetes. Explore the model with our interactive web app: compcat.princeton.edu
