What this research studies

We use gene-edited mice that lack IL-38 to see whether missing this protein makes inflammatory disease and fever worse. Where disease is worse in those mice, we give back human IL-38 to test whether it reduces inflammation. We also study two related receptors (IL-1R6 and IL-1R9) to learn how IL-38 works in the immune system. The experiments combine CRISPR mouse models and laboratory immune measurements to guide possible future treatments.

Who could benefit from this research

Good fit: People with autoimmune or other inflammatory conditions who have fevers or uncontrolled inflammation would be the most likely candidates for future trials based on these findings.

Not a fit: People with conditions that are not driven by inflammation, or those seeking immediate treatment today, are unlikely to benefit directly from this preclinical work.

Why it matters

Potential benefit: If successful, this work could point to new therapies that use IL-38 or similar drugs to reduce harmful inflammation and fever in autoimmune and inflammatory diseases.

How similar studies have performed: Prior lab studies have shown IL-38 can suppress inflammatory cytokines, but translating this into therapies for patients is still novel and untested.
