Tiny cell antennae that help islet hormones work together

Paracrine regulation of islet cell function by primary cilia

NIH-funded research Yale University · NIH-11397428

Researchers are looking at how tiny antenna-like structures on pancreatic islet cells help insulin, glucagon, and other hormones coordinate to control blood sugar in adults with type 2 diabetes.

What this research studies

This project uses mouse models where primary cilia (tiny antennae) on specific islet cells are removed to see how that changes hormone signaling and cell-to-cell communication. Scientists will apply advanced imaging and biochemical tests on isolated islets to track hormone release and how neighboring cells respond. The team will focus on alpha-cell signals (glucagon and GLP-1) and beta-cell signals (insulin and serotonin) to map how cilia mediate paracrine signaling. Understanding these mechanisms aims to explain why islet cell coordination fails in adult-onset diabetes.

Who could benefit from this research

Good fit: This grant does not enroll people; adults with adult-onset (type 2) diabetes could be future candidates for follow-up human studies or trials based on these findings.

Not a fit: People with type 1 diabetes, children, or patients needing immediate clinical treatment are unlikely to benefit directly from this preclinical research.

Why it matters

Potential benefit: If successful, this work could point to new targets for therapies that restore hormone coordination and improve blood sugar control in type 2 diabetes.

How similar studies have performed: Prior animal and cell studies suggest primary cilia influence islet signaling, but translating those findings into human therapies is novel and not yet proven.
