What this research studies

You'll hear that the team is studying how delta cells in your pancreas release somatostatin to influence nearby alpha and beta cells. They use high‑resolution imaging to watch calcium and cAMP signals across many cells inside intact islets and measure how those signals change insulin and glucagon release. The researchers also examine how somatostatin remodels the cell's F-actin scaffold to limit hormone secretion, using lab models and tissue samples. The goal is to find signaling steps that could be targeted by new diabetes treatments.

Who could benefit from this research

Good fit: Adults with type 2 diabetes or prediabetes, or adults willing to donate pancreatic tissue or blood samples for islet studies, would be most relevant.

Not a fit: People without islet hormone problems or those with long-standing type 1 diabetes who have little remaining beta-cell function may be less likely to benefit directly.

Why it matters

Potential benefit: If successful, this work could point to new drug targets that better normalize insulin and glucagon and improve blood sugar control.

How similar studies have performed: Previous laboratory studies using similar imaging and somatostatin-focused experiments have clarified islet signaling, but turning those findings into new diabetes medicines remains largely unproven.
