We are Pioneering the Research and Development of New Therapies to Enhance the Function of Regulatory T Cells (Tregs)

Dr. Shimon Sakaguchi, a member of our Scientific Advisory Board, discovered Tregs in 1995.

Dr. Stanley Appel, the Chair of our Scientific Advisory Board, and the research team at Houston Methodist Hospital leveraged this discovery by developing transformative therapies enhancing the immunomodulatory function of Tregs.

Tregs and How They Function

Tregs are a type of lymphocyte that modulate the body’s immune response.

The main functions of Tregs are:

Cells

Anti-inflammatory
Healthy Treg Cells

Pro-inflammatory Cells
and Cytokines

Healthy Tregs

Tregs are important anti-inflammatory immune cells involved in homeostasis. Tregs act on multiple immune cells to down-regulate the release of pro-inflammatory cytokines.

and Cytokines

Dysfunctional Tregs

When Tregs become dysfunctional, a cytokine-mediated inflammatory state can arise leading to neurodegenerative, autoimmune, and metabolic diseases.
