The leading cause of acute gastroenteritis linked to eating raw seafood disarms a key host defense system in a novel way: It paralyzes a cell's skeleton, or cytoskeleton. That finding, from UT ...

The endoplasmic reticulum (ER) is a crucial organelle present in eukaryotic cells, including human cells. The ER plays a vital part in making sure proteins are properly constructed, and that they get ...

When our body is attacked by a pathogen, the pathogen has to find ways to evade our immune system and invade our cells to cause infection and illness. Reporting in Cell, researchers have now ...

Now, in the first study of its kind, Cheryl Nickerson, lead author Jennifer Barrila and their colleagues describe the infection of human cells by the intestinal pathogen Salmonella Typhimurium during ...

Scientists have discovered that the most widely-used class of antifungals in the world cause pathogens to self-destruct. The research could help improve ways to protect food security and human lives.
