This paper develops a Gcg-Cre rat model to study GLP1-expressing cells in the brain and periphery, finding that homozygous rats show reduced Gcg mRNA and GLP1 protein, and chemogenetic activation suppresses food intake.

This study shows that blocking ghrelin receptor signaling in fasted male rats restores conditioned passive avoidance behavior and increases neural circuit activation in specific brain regions.

The paper investigates GLP1R-mediated GABAergic projections from the alBST to the PVN and their role in modulating HPA axis activity through synaptic circuit effects.

The paper analyzes gene expression in wild Ugandan red colobus to show SIV infection does not cause chronic immune activation and identifies upregulation of CD101 as a potential tolerance mechanism.
