A study led by IRB Barcelona and the IBMB-CSIC, reveals how the bacterium that causes cholera activates its virulence programme, uncovering a single amino acid as a critical contact point. The study opens new avenues for future therapies.
Using cryo-electron microscopy, researchers have solved five structures of the V. cholerae activation complex, revealing how virulence gene expression is triggered once the bacterium reaches the human intestine.
Researchers at IRB Barcelona and the IBMB-CSIC, in collaboration with EMBL Heidelberg and partners in the United States, mapped the infection process with unprecedented detail, unveiling how the cell’s transcription machinery is recruited to the DNA and virulence genes are transcribed.
Older adults who were exposed to heavy rainfall after Hurricane Harvey in 2017 faced a 3% increase in the risk of death within the following year, a new University of Michigan study found.
UF researchers are uncovering new insights into the complex relationship between the collection of microorganisms that live in the gut — known as the gut microbiota — and our health and immune system.
