This paper identifies that GLP-1(9-36) inhibits glucagon secretion via the glucagon receptor, while GLP-1(7-36) uses the GLP-1 receptor, revealing distinct mechanisms for glucagon suppression.

The paper shows that a loss-of-function variant in ZnT8 improves insulin secretion and protects against type 2 diabetes by enhancing glucose responsiveness and proinsulin conversion.

This study examines the electrophysiological and secretory properties of human β-cell lines EndoC-βH1 and -βH2, finding they closely resemble primary human β-cells in insulin secretion and ion channel behavior.

This study identifies T2D risk alleles in PAM that impair beta cell function through distinct effects on expression and catalytic activity, revealing a novel mechanism involving Chromogranin A.
