Biomaterials for Pancreatic Islet Replacement and Immune Tolerance in T1D-1

Timeslot: Friday, April 29, 2022 - 11:30am to 12:30pm
Room: Harborside Ballroom D-E, 4th Floor

About

The advent of new sources of beta cells, including from stem cells, has greatly advanced the potential of beta cell replacement as a functional cure for type 1 diabetes and some forms of type 2 diabetes. A major barrier that remains to be solved is blocking or modulating immune effectors while simultaneously promoting islet survival and function. Biomaterials play a central role in addressing this challenge, as vehicles for islet delivery, as microenvironments supportive of islet function, and as sites of immune modulation.
