Researchers Discover New Data on Protein Kinase A

By employing X-rays and neutron beams, a team of researchers have gleaned new information about protein kinase A, an omnipresent master control protein that helps regulate basic cellular functions such as energy consumption and interactions with neurotransmitters, hormones, and drugs.   More...

Infection by Meningitis Bacteria Depends on Dimerization State of Certain Host Cell Proteins

A team of molecular microbiologists has untangled the complex three-way interaction between the non-integrin laminin receptor, galectin-3, and the pathogenic bacterium Neisseria meningitidis.  More...

Artificial Sweeteners May Promote Development of Glucose Intolerance and Weight Gain

Recently published findings have stirred a controversy by indicating that noncaloric artificial sweeteners, a key components of diet drinks and foods, actually promote development of glucose intolerance, metabolic disease, and obesity by causing profound changes in the composition and function of the organisms that make up the intestinal microbiome.  More...

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...
