Macrophages make "sense" of obesity-driven acidity in the TME

Cell Chem Biol. 2024 Dec 19;31(12):2021-2023. doi: 10.1016/j.chembiol.2024.11.008.

Abstract

Obesity is a leading risk factor and a negative prognostic indicator for many cancers. In a recent issue of Science Immunology, Bagchi et al. identified that tumor-associated macrophages upregulate GPR65 in response to obesity-driven intratumor acidity resulting in reduced effector function to promote tumor growth.1.
