New Insights into Autism Spectrum Disorder Autism Spectrum Disorder (ASD) comprises a group of developmental disorders characterized by a wide range of symptoms, typically including impaired social interactions and excessive repetitive behaviors. Increasing evidence suggests that the pathophysiology of ASD involves an imbalance between two neuronal pathways, which are… Read More

Multiplexing Natural Products Discovery An organism’s metabolome is the total of all the small molecules that it produces. Efforts to identify bioactive natural products in the metabolomes of microbes, plants, and other organisms are often thwarted by metabolome complexity and the heterogeneous nature of the cell populations to which… Read More

Bingshan Li, associate professor of molecular physiology and biophysics, and David Weaver, associate professor of pharmacology, have been named to the 2018 class of Chancellor Faculty Fellows. The class comprises highly accomplished, recently tenured faculty from all corners of campus. The faculty members will hold the title of Chancellor Faculty Fellow and will be supported by… Read More

Claus Schneider, PhD, and colleagues have now discovered that curcumin is a “pro-drug” that is converted into reactive metabolites with anti-inflammatory activities. The metabolites of curcumin, produced by oxidation reactions, covalently bind to and inhibit proteins in the inflammatory NF-kappa-B signaling pathway. The researchers found that curcumin undergoes oxidation reactions readily in… Read More

Blocking a nerve-cell receptor in part of the brain that coordinates movement could improve the treatment of Parkinson’s disease, dyskinesia and other movement disorders, researchers at Vanderbilt University have reported. Their findings, published recently in the journal Neuron, focus on M4, a subtype of the muscarinic acetylcholine family of nerve cell (neuron) receptors… Read More

Researchers at Vanderbilt University Medical Center (VUMC) have demonstrated for the first time that it is possible to starve a tumor and stop its growth with a newly discovered small compound that blocks uptake of the vital nutrient glutamine. Their findings, reported in this week in Nature Medicine, lay the groundwork for… Read More

Escape of Insulin from Muscle Capillaries Key to the maintenance of homeostasis in a complex, multicellular organism is inter-organ communication by means of molecular signals that are delivered via the circulation. However, to gain access to the target tissue, these molecules must be able to traverse the tightly adherent… Read More

Vanderbilt University has signed separate licensing and research collaboration agreements with Lundbeck, a global pharmaceutical company based in Denmark, to develop a novel approach for treating schizophrenia. “We are excited to have the opportunity to work with our colleagues at Lundbeck to advance this promising new approach for treatment of a devastating… Read More

Preserving Neuronal Plasticity During Stress The prefrontal cortex (PFC) of the brain plays a key role in higher order mental processes such as cognition, motivation, attention, and memory. Stress can alter synaptic transmission in the PFC, and these changes may exacerbate symptoms of many psychiatric disorders. Glutamate is the… Read More

Evidence Against a Role for Eosinophils in Adipose Tissue Health Eosinophils are white blood cells distinguished by a multi-lobed nucleus and cytoplasm filled with granules that stain pink with hematoxylin and eosin stain. Known for their role in combatting parasitic infections and modulating allergic responses, eosinophils also regulate a… Read More
