Type VI secretion systems (T6SS) are sophisticated nanomachines that bacteria employ to inject effector proteins directly into neighbouring cells. These systems are structurally reminiscent of ...

Bacterial cells can “remember” brief, temporary changes to their bodies and immediate surroundings, a new Northwestern University and University of Texas-Southwestern study has found. And, although ...

Researchers have found that specific gut cells, BEST4/CA7+ cells, regulate electrolyte and water balance in response to bacterial toxins that cause diarrhea. Their findings show that these cells ...

Sometimes, transporting electrons from one cell to another is a team effort. In electroactive bacteria, that team is a group of proteins that shepherds electrons forward, passing them along like a ...

Researchers have discovered and characterized at the atomic level a mechanism that enables bacterial pathogens—including ...

"So, we are now colonizing that central space, and the bacterium is essentially ridding the body of the tumor." The post ...

Cells are constantly on the move, whether in a developing embryo or metastatic cancer. But how do cells adapt to new environments they encounter? Traditionally, scientists have believed that cells ...

Researchers at the University of Toronto have discovered that bacteria can drive stem cell regeneration to repair the intestinal lining after injury—uncovering an unexpected way in which the gut ...
