How IL-37 supports regulatory immune cells

The role of IL-37 in human regulatory T cells

NIH-funded research University of California, San Diego · NIH-11378848

This work looks at whether higher IL-37 in human regulatory T cells helps them better control harmful inflammation for people with autoimmune or inflammatory conditions.

What this research studies

Researchers will use human blood-derived regulatory T cells and laboratory T cell lines that are engineered to make more IL-37 or a mutant form to see how IL-37 changes cell behavior. They will measure FOXP3 and other molecular markers to determine whether IL-37 stabilizes Treg identity and improves their ability to suppress immune reactions. Transgenic mice expressing IL-37 will be used as supporting models because normal mice do not produce IL-37. The goal is to map the molecular steps by which IL-37 controls Treg function so the findings could guide future treatments.

Who could benefit from this research

Good fit: Ideal participants would be adults with autoimmune or inflammatory conditions or healthy volunteers willing to donate blood for immune cell studies.

Not a fit: People whose health problems are unrelated to immune overactivity or regulation (for example, purely structural or non-immune genetic conditions) are unlikely to benefit directly from this work.

Why it matters

Potential benefit: If successful, this could point to new ways to boost regulatory T cells and reduce autoimmune or inflammatory disease activity.

How similar studies have performed: Previous research shows IL-37 has broad anti-inflammatory effects and can promote tolerogenic dendritic cells, but applying IL-37 to stabilize human regulatory T cells is a relatively new direction.
