It’s hard to mimic the pancreas, despite the stellar treatment technology available to type 1 diabetics. Researchers like Juan Domínguez-Bendala are working hard on a cure for type 1 diabetes pathogenesis and, simultaneously, for even more hands-off treatment options.

Juan Domínguez-Bendala is Director of Stem Cell Development Research and an associate professor of surgery at the Diabetes Research Institute at the University of Miami’s Miller School of Medicine.
The primary goal of his researcher is to cure type 1 diabetes, and he addresses these efforts as well as exciting steps forward in a transplant therapy. The auto-immune cause of the disease means a cure must address two issues: immune modulation and regeneration of beta cells, which produce insulin. Therefore, advanced therapies also must address these two issues, but in a less permanent way. He describes some roads different researchers have taken to get as close as possible to curative hypotheses and how the therapies takes advantage of those findings.
Unlike beta cells in type 2 diabetes, type 1 patients have had their beta cells attacked and killed by their immune system. His lab is using induced pluripotent stems cells, where they are taken from skin, reprogrammed to go back in time, and then redifferentiated into, in this case, beta cells. They then put these cells into a protective case about the size of a credit card and implant just below the skin. Patients would ideally only need to return every 6 months for a new implantation.
They are also working on a way to induce cell growth inside a patient’s body by introducing a medicine that would cause beta cell regeneration naturally. They’ve identified a protein in our blood that makes beta stem cells proliferate, giving rise to new beta cells. Listen in for exciting leaps ahead for better type 1 diabetes treatment and the careful approach toward a final cure.
