Gene Editing Allows Pancreatic Islet Cell Transplantation Without Immunosuppression

The researchers utilized CRISPR-Cas12b gene editing technology to delete genes that code for incompatible cell surface antigens while adding genes coding for protective antigens thereby making the donor pancreatic cells invisible to the recipient’s immune system.Over a 12-week period, the limited number of gene-edited islet cells available for transplantation were able to reduce but not totally eliminate the recipients insulin requirement.  This proved the viability and functional integrity of the transplanted islet cells suggesting that transplantation of a larger complement of islet cells could provide a recipient’s total insulin requirement therapy curing diabetes without the need for ongoing immunosuppression with its often toxic side effects.https://medicalxpress.com/news/2025-08-gene-islet-transplant-human-functional.htmlhttps://www.nejm.org/doi/10.1056/NEJMoa2503822#diabetes #insulin #isletcells #transplantation #geneediting #immunosuppression
