Image: To adhere to catheters and start urinary tract infections, bacteria extend microscopic fibers with sticky proteins at their ends. Researchers have developed a vaccine that blocks the EbpA protein, visible as a white bulge above, and stops infections in mice (Photo courtesy of Dr. John Heuser, Washington University School of Medicine).

Blocking Binding of Bacteria to Fibrinogen Prevents Biofilm Formation and Catheter-Associated Bladder Infection in Mice

A team of molecular microbiologists has identified and targeted a critical step in biofilm formation and developed a vaccine that prevents catheter-associated urinary tract infections in mice.  More...

Risk of Cardiovascular Disease Linked to Apolipoprotein E Variants

The apoE4 variant form of circulating apolipoprotein E leads to increased risk of cardiovascular disease by blocking binding of the normal apoE3 form to the apoliprotein E receptor 2 in the membranes of endothelial cells lining the walls of blood vessels and by interacting with the receptor without stimulating production of anti-inflammatory nitric oxide.   More...

Activating Gene Slows the Aging Process by “Remote Control”

Biologists have identified a gene that can delay the aging process when triggered remotely in vital organs. The life scientists, working with fruit flies, switched on a gene called AMPK, which is a major energy sensor in cells.   More...
