How insulin-making beta cells are lost in type 1 diabetes

Studying the mechanisms of initiation and progression of Beta cell death in T1D

NIH-funded research Scripps Research Institute, the · NIH-11250020

This project makes patient-derived, blood-vessel-lined mini-pancreases on a chip to see how immune cells from people with type 1 diabetes attack insulin-producing beta cells.

What this research studies

From my perspective as a patient, researchers will turn blood cells from three people with type 1 diabetes and three healthy donors into stem cells and then grow the different parts of a tiny, vascularized pancreas on a microfluidic chip. They will make insulin-producing endocrine cells, blood vessels, tissue macrophages, and supporting fibroblasts so the mini-organ is matched to each donor. The team will also create clonal CD4 and CD8 T cells with known antigen specificity using CRISPR/Cas9 editing and TCR transfer to represent immune attackers. Each cell type and the assembled micro-organ will be tested for function (for example insulin release and vessel permeability) and then exposed to immune cells and inflammatory signals to watch how beta cells are injured.

Who could benefit from this research

Good fit: Ideal candidates are people with type 1 diabetes willing to donate blood or cells for research, plus healthy volunteers who can provide comparison samples.

Not a fit: People seeking immediate changes to their medical care or those unwilling to provide biological samples would not directly benefit from this lab-based project.

Why it matters

Potential benefit: If successful, this could reveal how immune cells destroy beta cells and point to targets for treatments that prevent or slow type 1 diabetes.

How similar studies have performed: Previous organ-on-chip and iPSC-derived islet work has provided useful insights, but making fully patient-matched vascularized micro-pancreases combined with engineered patient T cells is largely novel.
