Uncovering Protective Mechanisms in Pancreatic β-Cells to Enhance Their Survival in Type 1 Diabetes

Project description

Pancreatic β-cell endurance

Type 1 diabetes (T1D) is an autoimmune disease caused by the destruction of pancreatic β-cells, leading to insulin deficiency. Emerging evidence suggests that β-cells may influence their own survival. With the support of the Marie Skłodowska-Curie Actions programme, the Beta_cell_protection project will explore the protective role of three genes, HLA-E, IDO1 and BiP, in human pancreatic β-cell survival. These genes were identified by single-cell RNA sequencing of β-cells from people with T1D. Researchers will test whether enhancing their expression improves β-cell endurance under immune/inflammatory stress in human β-cell models and stem cell derived β-like cells. By defining the underlying mechanisms, the project aims to inform therapies that preserve β-cell function and endogenous insulin production.

Objective

Type 1 Diabetes (T1D) is a chronic autoimmune disease characterized by the destruction of pancreatic β-cells, leading to insulin deficiency and severe complications, including cardiovascular disease, neuropathy, and vision impairment. Despite extensive research, the exact cause of T1D remains elusive, and the disease remains incurable. Emerging evidence suggests that β-cells may play an active role in their own demise, alongside the well-documented immune attack. Recent findings have identified protective genes within β-cells that may help them resist immune-mediated destruction.
This project aims to investigate the role of three protective genes—HLA-E, IDO1, and BiP—in preserving β-cell function and survival under autoimmune stress. These genes were identified via a bioinformatic approach that analysed single cell RNA sequencing of β-cells from individuals affected by T1D. The study will begin by modulating the expression of these genes in human EndoC-βH1 cells and human islets, followed by an immune attack model of co-culture with the activated CD8+ T-cells. The goal is to determine which gene(s) offers the most significant protection against β-cell destruction.
Subsequently, the most promising gene(s) will be further evaluated in stem cell-derived β-like cells, which will undergo in vivo testing in immune incompetent NSG mice to mimic more physiologically relevant conditions. The implanted cells will be evaluated by in vivo imaging using an intravital microscopy platform. By silencing or overexpressing these genes, we aim to elucidate the mechanisms that contribute to β-cell resilience, providing insights that could lead to novel therapeutic strategies for enhancing β-cell survival in T1D patients.
This project represents a critical step forward in understanding the interplay between β-cells and the immune system in T1D. It has the potential to uncover new targets for therapy, ultimately improving the quality of life for individuals living with T1D.
