Three Labs Unite to Tackle Type 1 Diabetes Through Immune System Research

Scientists at Joslin Diabetes Center are collaborating on a multi-pronged approach to understand and potentially reset the immune system in Type 1 diabetes. The work focuses on how T cells develop and why they mistakenly attack insulin-producing cells.

Key takeaways

Type 1 diabetes occurs when T cells in the immune system attack the pancreas's insulin-producing cells, treating them as if they were infected.
Researchers at Joslin are using a three-pronged collaborative approach to study how T cells develop and their role in Type 1 diabetes.
Understanding thymic development—how T cells are created in the thymus gland—is central to this research direction.
Multiple clinical trials have explored ways to intervene in this immune process, building the foundation for new research.

The Root Cause: Why the Immune System Attacks

In Type 1 diabetes, the immune system makes a critical mistake. T cells—a type of white blood cell designed to protect the body—mistakenly identify and attack the insulin-producing beta cells in the pancreas. The immune system responds to these cells as if they were infected with a virus or bacteria, destroying them in the process.

This misguided immune response is the core problem researchers are trying to understand and ultimately prevent.

A Collaborative Research Model

Scientists at Joslin Diabetes Center have formed a unique partnership to tackle this problem from multiple angles. Assistant Professor Tom Serwal and collaborators Stephan Knauer and Pungy are combining their expertise in a coordinated, three-pronged research effort designed to move toward a cure.

Rather than working in isolation, the team brings different perspectives and skill sets to bear on the same challenge, increasing the likelihood of breakthrough insights.

Focus on T Cell Development

A key part of this research examines how T cells develop within the thymus—a gland in the chest that trains immune cells to recognize the body's own tissues and leave them alone. If something goes wrong in this developmental process, T cells may fail to learn this critical distinction.

By understanding how thymic development affects Type 1 diabetes development, researchers hope to identify points where the process goes awry and where intervention might be possible.

Building on a Foundation of Clinical Trials

This research doesn't start from scratch. A number of clinical trials have already explored ways to intervene in the immune attack on beta cells. The collaborative approach at Joslin builds on these findings, using what researchers have learned to refine and expand their understanding.

This iterative process—learning from past trials and studies—is how scientific progress toward new treatments is made.
