TL1A, a novel alarmin in airway, intestinal, and autoimmune disorders.

Summary: Think of your body’s immune system as a home security network. Scientists have identified a specific "burglar alarm" molecule called TL1A. It is released by the lining of your lungs and intestines to signal danger. However, in some people, this alarm gets stuck in the "on" position, causing chronic inflammation in diseases like severe asthma, ulcerative colitis, rheumatoid arthritis, and psoriasis.

The good news is that researchers have developed a way to silence this false alarm. A new drug called tulisokibart acts like a mute button for TL1A. Early studies show it is effective at calming the immune system and inducing remission in patients with gut inflammation, with promising trials underway for asthma sufferers.
