Researchers at University College London found a natural way to stop inflammation once it's no longer needed. This discovery could lead to new treatments for chronic diseases.

Inflammation is an essential defense mechanism that helps our bodies fight off infections and injuries. However, when it continues unchecked, it can cause serious conditions like arthritis, heart disease, and diabetes. Until now, scientists didn't fully understand how the body transitions from an active immune attack to a healing phase.

Researchers at University College London have identified a biological process that helps the body shut down inflammation once it's no longer needed. They found that small fat-based molecules called epoxy-oxylipins act as natural regulators of the immune response.

To explore this process, researchers conducted an experiment in healthy volunteers. Participants received a small injection of UV-killed E. coli bacteria in their forearm, which triggered a temporary inflammatory response. Volunteers were divided into two groups: one group received a drug that blocked an enzyme called soluble epoxide hydrolase (sEH), while the other group received a placebo.

The results showed that participants who received the drug experienced faster pain resolution and had significantly lower levels of immune cells linked to chronic inflammation and disease. Notably, the medication did not meaningfully change visible symptoms like redness or swelling.

Further investigation revealed that one specific epoxy-oxylipin, 12,13-EpOME, works by suppressing a protein signaling pathway known as p38 MAPK, which drives monocyte transformation.
