Gastrin producing syngeneic mesenchymal stem cells protect non-obese diabetic mice from type 1 diabetes.

Autoimmunity 2022 03 9;55(2):95-108. Epub 2021 Dec 9.

Department of Microbiology and Immunology, College of Medicine, Medical University of South Carolina, Charleston, SC, USA.

Progressive destruction of pancreatic islet β-cells by immune cells is a primary feature of type 1 diabetes (T1D) and therapies that can restore the functional β-cell mass are needed to alleviate disease progression. Here, we report the use of mesenchymal stromal/stem cells (MSCs) for the production and delivery of Gastrin, a peptide hormone that is produced by intestinal cells and foetal islets and can increase β-Cell mass, to promote protection from T1D.
