Studies have demonstrated a critical role of the cytokines thymic stromal lymphopoietin (TSLP), IL-33, and IL-25, produced by epithelial and other cells at mucosal surfaces in response to a wide range ...

Researchers have resolved a 50-year-old scientific mystery by identifying the molecular mechanism that allows tissues to ...

Deep in the folds of the intestine, in microscopic pockets called crypts, a quiet surveillance system is always at work. Stem cells lining the gut wall are not just rebuilding tissue—they are ...

Despite a wealth of available treatments to control the symptoms of chronic asthma, the lung disease has no cure. The discovery of an unexpected cause of asthma could change that. A glitch in the ...
