Little-known protein helps the body restrain scar-forming signals
Scientists from the U.K. and U.S. have identified how a specific protein, LTBP1, regulates the TGFβ signaling molecule to prevent excessive scar tissue formation. This discovery offers new potential pathways for treating fibrosis, a condition that causes organ damage and contributes to millions of deaths annually.
Why it matters
Understanding the mechanism behind fibrosis could lead to breakthrough medical treatments for chronic organ diseases.

DOI: 10.1038/s41467-026-75834-8 U.K. and U.S. scientists have uncovered an important piece of the puzzle in the signaling pathway that causes damaging scar tissue to build up in the body, raising hopes for future treatments. A team from the University of Manchester and University of Connecticut have revealed how a little-known protein helps keep one of the body's most powerful biological signals under tight control. Their findings, published in Nature Communications , could eventually help researchers develop new ways to tackle conditions linked to fibrosis, a process in which excessive scar tissue forms in organs and prevents them from working properly.
