A Three-Part Strategy for Type 1 Diabetes: Reset, Regulate, Regenerate

Researchers at Joslin Diabetes Center are pursuing an approach that tackles Type 1 diabetes from three angles at once: stopping immune attacks on beta cells, preventing them from restarting, and restoring the body's natural insulin-producing capacity.

Key takeaways

Type 1 diabetes involves both a faulty immune system (attacking beta cells) and loss of insulin-producing cells—addressing only one problem has not led to a cure
The three-part strategy aims to reset harmful immune cells, regulate the immune system to prevent future attacks, and regenerate beta cells
This research is exploratory and collaborative; it represents a different conceptual approach but is not yet proven in humans
Each step targets a different part of the problem, reflecting the idea that a permanent solution may require addressing all three components

Why Previous Approaches Haven't Worked

Type 1 diabetes involves two interconnected problems. The immune system mistakenly produces T cells that attack and destroy the body's beta cells—the cells responsible for making insulin. Over time, as more beta cells are lost, the body loses its ability to regulate blood sugar. Researchers have tried to solve this puzzle by targeting either the immune problem or the beta cell problem separately, but neither approach alone has led to a cure.

A New Framework: Three Steps, One Goal

Scientists at Joslin Diabetes Center—including Dr. Thomas Wald, Dr. Stephan Kissler, and Dr. Paul Yi—are pursuing a different strategy. Instead of solving one piece of the puzzle, they are working together on all three at once: reset, regulate, and regenerate.

The idea is straightforward in concept but complex in execution. First, the immune system must be reset by eliminating the destructive T cells. Second, the immune system must be regulated so it stops making those harmful cells in the first place. Third, the body's beta cells must be regenerated to restore insulin production.

What Each Research Team Is Working On

Dr. Wald is focused on the reset phase: identifying and targeting the specific immune cells primed to destroy beta cells, then replacing them with healthy cells. This would stop the autoimmune attack.

Dr. Kissler is working on regulation by studying genes specific to Type 1 diabetes. His goal is to manipulate immune cell behavior so that the destructive T cells are kept away from beta cells, preventing the disease from starting again after reset.

Dr. Yi is pursuing the regenerate phase. He has identified a biological pathway called beta trophin that appears to promote beta cell regeneration, both within the body naturally and potentially as a drug-based therapy.

What This Means for People with Type 1 Diabetes

This research represents a shift in how scientists are thinking about a cure for Type 1 diabetes—as a problem that may require a coordinated, multi-step solution rather than a single breakthrough. The three-part strategy is still in the exploratory phase and has not yet been tested in humans. However, it reflects a growing recognition that addressing autoimmunity alone or beta cell loss alone is unlikely to be enough.
