Powering H. pylori pathogenesis
Feb. 6, 2020—Timothy Cover and colleagues report new insights into the sources of energy used by a bacterial “machine” linked to the pathogenesis of stomach cancer.
Vaccine Program receives NIH renewal of VTEU
Feb. 5, 2020—The Vanderbilt Vaccine Research Program has received a grant from the NIH to continue its work as one of the nation’s nine Vaccine and Treatment Evaluation Units.
Zinc uptake by a deadly pathogen
Jan. 13, 2020—The increasingly antibiotic-resistant bacterium Acinetobacter baumannii requires zinc to cause infection, and Vanderbilt researchers have identified the zinc uptake system it uses.
Structural views of a C. diff toxin
Jan. 10, 2020—D. Borden Lacy and colleagues used cryo-electron microscopy to define the structure of a C. diff toxin, providing a framework for the design of novel therapeutics.
RSV transmission in the Middle East
Nov. 14, 2019—Understanding how RSV is transmitted, which strains dominate and how new strains emerge around the globe will guide better vaccine and anti-viral drug design.
Imaging host-pathogen battle for metal
Oct. 31, 2019—An unprecedented view of bacterial products within infected tissues opens new opportunities to explore infection biology and devise novel therapeutic strategies.
A new regulator of B cell development
Oct. 8, 2019—New findings establish a role for the pro-inflammatory molecule IL-33 in the early development of antibody-producing B cells.
New test assists physicians with quicker treatment decisions for sepsis
Oct. 3, 2019—Rapid blood culture diagnostics for patients with bacterial bloodstream infections delivered final results in 12 hours versus the two to three days required for conventional testing.
Treating C. diff: new purpose for an old drug?
Sep. 24, 2019—An inexpensive generic drug once used to prevent gastrointestinal ulcers in people taking daily NSAIDs protects against C. diff infection in mice.
Microvilli in motion
Sep. 19, 2019—Live cell imaging studies have revealed that microvilli — finger-like protrusions on the surface of epithelial cells — move and collide as they form the brush border.
Low oxygen and antibody responses
Apr. 25, 2019—Mark Boothby and colleagues are exploring the factors that contribute to antibody production and quality, which are key to our defense against pathogens and response to vaccines.
How bugs overcome host defenses
Apr. 11, 2019—Vanderbilt researchers led by Eric Skaar are probing the mechanisms bacteria use when faced with nutrient starvation — a host defense strategy called “nutritional immunity.”
