Type 1 diabetes results from autoimmune destruction of insulin-producing β cells, leading to lifelong insulin dependence and associated complications. This PhD project investigated combination therapies aimed at preserving β-cell function and supporting long-term glycemic control.
The work demonstrated that a short course of low-dose anti-CD3 antibodies followed by the DPP-4 inhibitor MK626 induced durable diabetes remission in new-onset diabetic NOD mice by restoring β-cell function, resolving insulitis, and repairing islet vasculature.
Additionally, the study evaluated commonly used immunosuppressants in islet transplantation, showing that tacrolimus best preserved duct cell angiogenic, proliferative, and reprogramming potential while effectively reducing inflammatory cytokine expression.
These findings provide important preclinical insights for future clinical trials, highlighting the value of combination therapies that both modulate the immune response and support β-cell health to improve type 1 diabetes treatment outcomes.
