Vanderbilt scientists test potential new way to treat anemia

Apr. 10, 2018—Treatment of anemia caused by chronic kidney disease or other diseases often requires repeated — and costly — injections or infusions of an artificial form of the hormone erythropoietin (EPO), which stimulates production of red blood cells.

Graphene material strengthens nerve signaling in the brain

Mar. 1, 2018—Less than 20 years after it was developed, a thin, resilient sheet of carbon atoms with remarkable properties known as graphene is transforming biomedical fields as far flung as tissue engineering, neuroprosthetics and drug discovery.

Vanderbilt study finds natural chemical helps brain adapt to stress

Mar. 28, 2017—A natural signaling molecule that activates cannabinoid receptors in the brain plays a critical role in stress-resilience — the ability to adapt to repeated and acute exposures to traumatic stress, according to researchers at Vanderbilt University Medical Center.

VUMC investigators find pathogens work together to infect host

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.

Study links COPD with increased bacterial invasion

Apr. 28, 2016—Chronic obstructive pulmonary disease (COPD) is a common smoking-related lung illness and the third leading cause of death in the United States. Scientists have long believed that inhaling toxic gases and particles from tobacco smoke causes inflammation of the small airways in the lungs, leading to the development of COPD.

Study finds rerouting bile acids may offer simpler alternative to gastric bypass surgery

Jul. 21, 2015—A new surgical procedure could offer a simpler approach to achieve some of the same weight-loss and metabolic benefits associated with gastric bypass surgery, researchers at VUMC report.

Study team uses metabolomics to study longevity

Apr. 30, 2015—The keys to longevity have been a source of curiosity and the basis of many research studies for years, yet the mechanisms underlying a person’s ability to live a long life are still not fully understood.
