A Three-Part Strategy: How Joslin Researchers Are Approaching Type 1 Diabetes

Type 1 diabetes involves a fundamental breakdown in immune tolerance. In people with Type 1, T cells—a type of white blood cell—mistakenly attack the insulin-producing beta cells in the pancreas. Over time, this autoimmune attack destroys enough beta cells that the body can no longer produce the insulin it needs to regulate blood sugar.

For decades, researchers have tried to solve this problem by targeting either the autoimmunity (stopping the immune attack) or the beta cell loss (regenerating new cells). But progress has been limited when these approaches are pursued independently.

Researchers at Joslin Diabetes Center—including Dr. Stephan Khislal, Dr. Pong Ye, and Dr. Tom Wald—are proposing a different strategy. Rather than addressing one piece of the puzzle, they outline three coordinated steps toward a potential permanent solution.

The first step is to reset the immune system by eliminating the T cells that are actively attacking beta cells. The second is to regulate the immune system so it stops producing these destructive cells in the future. The third is to regenerate the body's natural islet cells—the clusters of beta cells in the pancreas—using what the researchers describe as a newly discovered biologic approach.

By addressing the autoimmune problem and the cell loss problem together, rather than in isolation, the team believes this framework offers a more complete path forward.

This research represents a conceptual shift in how scientists think about a permanent solution to Type 1 diabetes. It highlights why approaches that target only the immune system or only beta cell regeneration may fall short on their own.

The work at Joslin is still in the research phase. This three-part strategy is a proposed framework for investigation, not a treatment available to patients today. But it offers a blueprint for the kind of coordinated thinking that may be necessary to move closer to a cure.
