Effect of Immunosuppressive Drugs on Glucose-Stimulated Insulin Secretion: Concentration-Response Studies in Dynamic Perifusion Assays

Sung-Ting Chuang, Brandon Watts, Oscar Alcazar, Péter Buchwald

This study examines how immunosuppressive drugs affect glucose-stimulated insulin secretion using dynamic perifusion assays, finding concentration-dependent inhibition with varying patterns among drug types.

Assessing the Rate-Dependence of the First Phase of Glucose-Stimulated Insulin Secretion: Dynamic Perifusion Studies with Isolated Human Pancreatic Islets

Péter Buchwald, Sung-Ting Chuang, Brandon Watts, Oscar Alcazar

This study investigates the rate-dependence of the first phase of glucose-stimulated insulin secretion using dynamic perifusion of human pancreatic islets, finding it follows a sigmoid function of the glucose gradient.

Post-Inhibitory Rebound by δ-Cells Transforms Inhibition into Excitationand Redefines Islet Plasticity.

Alejandro Tamayo, Dayleen Hakim Rodriguez, Elisabeth Pereira, Sergio Camacho-Becerra, Luciana Mateus Gonçalves, Per-Olof Bergreen, Madina Sokolov, Rafael Arrojo e Drigo, Oscar Alcazar, Rayner Rodriguez‐Diaz

This paper identifies post-inhibitory rebound (PIR) in pancreatic islets as a mechanism converting δ-cell inhibition into excitation, revealing dynamic paracrine signaling rather than static inhibition.
