The regulator of G protein signaling RGS9 supports insulin secretion in male mouse islets

LAURA REININGER, SARAH FERRAGNE, Scott A. Campbell, Caroline CT Tremblay, Mélanie Éthier, J. Ghislain, Vincent Poitout

This study shows RGS9 supports glucose-stimulated insulin secretion in male mouse islets by dampening inhibitory signaling through Gi/o.

Free fatty acid receptor 4 agonists stimulate insulin secretion via different mechanisms in mouse versus human islets

LAURA REININGER, Muhammad Rehman, Ryan Hart, SARAH FERRAGNE, Caroline CT Tremblay, Mélanie Éthier, Amelia Bouabcha, Michelle E. Kimple, Julien J. Ghislain, Mark O. Huising, Vincent Poitout

This study compares the mechanisms of FFAR4 agonist-induced insulin secretion in mouse and human islets, finding indirect effects in mice and direct effects in humans.

Fatty acids from adipocyte lipolysis stimulate insulin secretion

Camille Fournes-Fraresso, Émilie Courty, Ebru Temiz, Marie Marques, Stéphanie Cassant‐Sourdy, LAURA REININGER, Anouk Pellerin, Laure Rolland, Ayse Sumeyra Dereli, Étienne Mouisel, Vincent Poitout, Matthieu Raoux, Patrick Gilon, Jean‐Sébastien Annicotte, Dominique Langin, Pierre‐Damien Denechaud

This study shows that fatty acids from adipocyte lipolysis stimulate insulin secretion via FFAR4 and FFAR1 receptors, highlighting adipose-islet crosstalk in metabolic regulation.
