Retraining the Autoimmune System in Type 1 Diabetes

Tom Serwold, Ph.D., works with beta cells in the diabetes research section of Joslin Diabetes Center

Thomas Serwold, Ph.D., is an Investigator in the Section on Immunobiology at Joslin Diabetes Center.

In the autoimmune attack behind type 1 diabetes, you can think of T cells as an improperly trained SWAT team that homes in on insulin-producing beta cells rather than pathogens. Research at Joslin seeks to sort out the diabolically complicated details of their attack and to work toward steps that can be taken to stop it.

In one project, Thomas Serwold, Ph.D., employs mouse models to understand the cells within the thymus that help T cells to develop, and whether these cells can be altered to prevent autoimmune T cells from developing in the first place.

“Throughout life, T cells are produced in the thymus, each with a unique receptor that can bind only to certain protein fragments derived from pathogens,” explains Dr. Serwold. “Also within the thymus, epithelial cells act like teacher cells for the T cells, preventing those that might target the body’s own cells from graduating and leaving the thymus.”

“Developing techniques to manipulate the functions of these teacher cells will tell us a lot about how the autoimmune T cells that drive type 1 diabetes come to develop, and how they might be eliminated,” he adds.

    Hi, I have been a diabetic for 18 years, I believe finding a cure is like finding World Peace, But I was wondering, have you ever tried, family members with their Cells, injecting , creating, implanting, because they are the best mattch. Thanks Pat.
