Oct. 27, 2023—Vanderbilt research shows that commensal gut microbes impact the host-pathogen competition for iron and has implications for therapeutic strategies aimed at preventing pathogens from acquiring essential nutrients.
Feb. 23, 2017—DNA replication is an extraordinarily complex multi-step process that makes copies of the body’s genetic blueprint. It is necessary for growth and essential to life. Now researchers at the California Institute of Technology (Caltech) and Vanderbilt University have found evidence that one of those steps may involve the telephone-like transmission of electrical signals regulated by a chemical “switch.”
Nov. 3, 2016—Pseudomonas aeruginosa and Staphylococcus aureus — two pathogens that frequently co-infect the lungs of patients with cystic fibrosis — appear to cooperate with each other, Vanderbilt investigators have discovered. When pseudomonas is starved for metal by the host, it shuts down the production of factors that would normally kill staph, promoting a co-infection.
Oct. 22, 2015—Walter Chazin, Ph.D., director of the Vanderbilt Center for Structural Biology, is a recipient of a 2016 Fellow of the Biophysical Society award.
Jul. 30, 2015—Researchers at Vanderbilt University have established the molecular basis for the function of Replication Protein A (RPA), a DNA binding protein that is a crucial “scaffold” for genome replication, response to damage and repair.
Feb. 26, 2015—The Vanderbilt University Department of Biochemistry will host a two-day symposium March 6-7 to honor the 60th birthday of Walter Chazin, Ph.D., director of the Center for Structural Biology.
Feb. 21, 2013—Vanderbilt investigators report new insights to the workings of calprotectin, an immune system protein that “starves” bacterial pathogens of the metal nutrients they require.
