The Immune Problem Was Always the Problem: How Engineered "Stealth" Beta Cells Finally Address It

Islet transplantation has worked as a diabetes treatment for decades. The procedure itself isn’t the problem — surgeons can take insulin-producing cells from a donor pancreas, infuse them into the hepatic portal vein, and watch a Type 1 diabetic patient achieve near-normal blood glucose without injecting insulin. It’s been demonstrated repeatedly since the Edmonton Protocol in 2000. The reason it never became standard care has nothing to do with the transplant. It’s what comes after: to keep those cells alive in a foreign body, patients need immunosuppression aggressive enough to cause kidney damage, increase cancer risk, and leave them vulnerable to infections that can kill them. You’re trading one chronic disease for a cocktail of others.
