    New way to stimulate learning?

    Mar. 14, 2019, 1:00 PM by Bill Snyder The vagus nerve connects the brain and organs throughout the body. Vagus nerve stimulation (VNS) implants have been used for more than 20 years to treat drug-resistant epilepsy. In a study published in the Journal of Neuroscience,… Read More

    Reprogramming cells for kidney repair

    Mar. 14, 2019, 10:45 AM by Kelsey Herbers Chronic kidney disease is on the rise worldwide. Approaches to develop regenerative or cellular therapies are hindered by the complex cellular structure of the kidney, which is composed of about 1 million microscopic “filters” called nephrons. Lauren Woodard, PhD, and… Read More

    In Search of Synergy

    In recent years, the number of complex diseases such as cancer and drug resistant infections that are treated with multiple drugs has rapidly increased. Through combining drugs, one hopes to obtain synergy either by increasing potency (so the desired effect can be achieved with lower drug doses) or increasing efficacy… Read More

    Vanderbilt scientists report new modeling of brain signaling

    Mar. 7, 2019, 12:12 PM (AdobeStock) by Bill Snyder The release of neurotransmitters and hormones in the body is tightly controlled by complex protein machinery embedded in cell membranes. Manipulating that machinery with drugs could improve treatment of disorders ranging from diabetes to Parkinson’s disease. Progress has been slow, however,… Read More

    Achilles’ heel for kidney cancer

    Feb. 28, 2019, 3:35 PM by Meredith Jackson Renal cell carcinoma (RCC) is an aggressive form of kidney cancer that tends to recur even after treatment with targeted cancer therapies or immunotherapies. One commonly mutated pathway in RCC and in all cancers is the PI3K-AKT signaling axis. P13K and AKT enzymes… Read More

    Novel DNA repair mechanism preserves genome integrity: study

    by Leigh MacMillan As David Cortez, PhD, tells the story of his research team’s latest discovery, he shakes his head in disbelief. “I’m just astounded,” said Cortez, Ingram Professor of Cancer Research and professor of Biochemistry. The investigators, led by postdoctoral fellow Kareem Mohni,… Read More

    Modulating stress circuits

    Feb. 14, 2019, 12:00 PM by Leigh MacMillan (iStock) Stress contributes to psychiatric diseases including depression, eating disorders and addiction. Neurons that express the stress signal corticotropin releasing factor (CRF) in a brain region called the BNST are thought to promote negative responses to stress. Danny Winder, PhD,… Read More

    Adhesion protein optimizes border

    Feb. 14, 2019, 10:45 AM by Leigh MacMillan (iStock) The epithelial cells that line the intestines build a specialized cell surface — the “brush border” — that processes and absorbs nutrients, and defends against pathogens. The brush border consists of thousands of finger-like membrane protrusions (microvilli) on each… Read More
