Gut Protein Regulates Immune Response

Researchers at Weill Cornell Medicine have identified a protein produced by gut immune cells that regulates the intestinal immune system by simultaneously defending against pathogens and maintaining tolerance toward beneficial gut bacteria. A study led by investigators from the institution reveals that this protein is essential for orchestrating the delicate balance required to protect the body from infection while preventing unnecessary immune reactions to the microbiome. This discovery underscores the sophisticated mechanisms the gut
