New methods to visualize bacterial cell-to-cell communication

Most bacteria are able to communicate with each other by secreting signaling molecules. Once the concentration of signals has reached a critical density ("the Quorum), the bacteria are able to coordinate their behavior. Only ...

Deciphering cellular 'roadmap' of disease-related proteins

University of Toronto researchers are helping demystify an important class of proteins associated with disease, a discovery that could lead to better treatments for cancer, cystic fibrosis and many other conditions.

Bacteria communicate to help each other resist antibiotics

New research from Western University unravels a novel means of communication that allows bacteria such as Burkholderia cenocepacia (B. cenocepacia) to resist antibiotic treatment. B. cenocepacia is an environmental bacterium ...

Pathogen turns protein into a virulence factor in one easy step

To infect its host, the respiratory pathogen Pseudomonas aeruginosa takes an ordinary protein usually involved in making other proteins and adds three small molecules to turn it into a key for gaining access to human cells. ...

Protein regulates protein folding in cells during stress

(Phys.org)—Cornell researchers have discovered that a protein known for moving cells around in the body also helps regulate a cellular organelle responsible for generating one-third of all proteins in the human body.

Scientists focus on quorum sensing to better understand bacteria

The relatively new field in microbiology that focuses on quorum sensing has been making strides in understanding how bacteria communicate and cooperate. Quorum sensing describes the bacterial communication between cells that ...
