简介：
Overview
This study investigates the role of C-C motif ligand 5 (CCL5) in the hypothalamus and its impact on insulin signaling and glucose metabolism. By using a micro-osmotic pump to deliver the antagonist Met CCL5, researchers observed changes in insulin sensitivity and glucose tolerance in mice.
