Researchers at the UNC School of Medicine have found that a metabolic enzyme called Acetyl-CoA Carboxylase causes T cells to store fat when they are in solid tumors, rather than burning fat for energy.

Researchers Explore Role of Plasma Membrane Pump in Calcium Signaling
Rockville, Md. (September 1, 2022)—Research published ahead of print in the journal Function suggests the plasma membrane Ca2+ ATPase (PMCA) pump helps regulate cytosolic calcium signaling. Cytosolic calcium is found within the cells’ intracellular fluid—the cytosol is one such liquid—and…
