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 ...

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of cells. By systematically identifying thousands of rapidly evolving ...

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 ...

Darwin's theory of natural selection provides an explanation for why organisms develop traits that help them survive and reproduce. Because of this, death is often seen as a failure rather than a ...

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings, published in the journal Nature Communications, describe how ...

Researchers developed a technique that attaches a cancer-killing toxin to modified bacteria capable of entering tumor cells. Once inside, the toxin is released to destroy the cancer cell, ...
