Epithelial cells form the body's frontline barriers, helping keep microbes, toxins and other harmful substances out. Yet these protective cells are constantly exposed to threats, including microbial infections. Some bacteria produce pore-forming toxins that can oligomerize and act like microscopic drills, perforating the cell's plasma membrane.

The “glue” holding your cells together has a surprising second job
Scientists have discovered that E-cadherin, a protein best known as the “glue” holding cells and tissues together, has a surprising second job: helping epithelial cells swallow nearby dead cells. Using live zebrafish and mouse embryos, researchers found that cells can dramaticall

Cancer stem cells have an “energy addiction” scientists may be able to exploit
High-risk MDS stem cells appear to have an unexpected “energy addiction,” relying far more heavily than healthy blood-forming cells on a molecule called NAD. Disrupting this energy pathway selectively weakened the cancer-driving cells, revealing a potential new target for treatme
