Research Direction

The Ren laboratory at CIMR works how cell-to-cell interactions within the pancreatic islet balance Ca²⁺ activity and hormone secretion, as well as maintain blood glucose homeostasis. Through the integration of experimental, computational and theoretical methods, we aim to gain new insights for disease treatment.

Major Research Projects

1. Novel glucagon and somatostatin sensor to detect the endogenous hormone secretiondynamics

2. Mechanisms of glucose sensitivity regulation in diabetic pancreatic islets

3. Invivo pancreatic islet Ca²⁺and hormone release imaging

Major Contributions

1. Discovered that the alpha and beta cells in pancreatic islets are globally phase-locked. Build a mathematical model to highlight the importance of cell-cell interactions to generate stable but tunable islet oscillation patterns. This challenges the traditional view that oscillation patterns originate mainly from the heterogeneity of beta cells. (Nature Communications, 2022).

2. Using a novel extracellular Zn²⁺probe to observe insulin vesicle secretion, it was found that the secretion capacity of islet β cells exhibits exponential distribution heterogeneity. (Nature Metabolism, 2024).
