For generations, the cells lining our intestines were understood as quiet architects — rebuilding what time and use wore away. A new study from Hebrew University, published in Nature Immunology, reveals that these same stem cells are also guardians, capable of detecting Salmonella and transforming themselves into antimicrobial defenders before infection can take hold. The discovery not only explains why most foodborne illness resolves without intervention, but opens an unexpected window into the origins of chronic conditions like Crohn's disease — suggesting that the boundary between regenerat
