Like glucagon, multiple factors similarly regulate ... the role of GPCRs in islet biology and hormone secretion, and how signaling in the cell through these receptors is disrupted in diabetes.

At the heart of this discovery lies the role of glucagon-like peptide-1 (GLP-1 ... effects that suggest that increasing central GLP-1 signaling could reduce cocaine seeking.

Glucagon has the opposite effect in the body ... The new findings highlight an important and previously unknown role of electrical signaling that occurs through open cell connections between ...
