Jul. 29, 2019, 8:30 AM by Bill Snyder The failure of pancreatic beta cells to release appropriate amounts of insulin in response to rising blood glucose levels is a hallmark of type 2 diabetes. During the past decade researchers have shown that microtubules — part of the cell’s… Read More

By Deborah Roby Irina Kaverina. The Cell and Developmental Biology labs of Irina Kaverina and collaborators Guoqiang Gu and Chris Wright recently published work in Current Biology that presents a newly discovered means by which the pancreas maintains glucose homeostasis. This work illuminates the crucial steps pancreatic β cells take to… Read More

Jul. 25, 2019, 8:30 AM by Kelsey Herbers Evidence indicates men have higher incidence of chronic kidney disease and quicker renal decline than premenopausal women. However, sex differences in the expression and activation of the EGF receptor (EGFR), which mediates progressive renal injury, are largely unexplored. Ming-Zhi… Read More

Jul. 18, 2019, 8:32 AM by Tom Wilemon The Vanderbilt Center for Immunobiology (VCI) has relaunched its mission with a greater focus on human immunology, an endeavor supported by additional researchers, more funding support and designation as a Center of Excellence. “We are focusing on human immune diseases and trying… Read More

Jul. 15, 2019, 8:30 AM by Sanjay Mishra Retinal ganglion cells (RGCs) make up the optic nerve. When RGCs degenerate due to elevated intraocular pressure caused by glaucoma, vision is lost. Cells surrounding RGCs called Müller glia maintain a healthy ionic environment through a process called potassium siphoning, where Müller glia… Read More

Jul. 11, 2019, 9:32 AM This illustration shows the H. pylori bacterium and a close-up of its “injector” at the stomach lining. Researchers at Vanderbilt University and the University of Michigan in Ann Arbor have obtained the first high-resolution image of a molecular “machine” used by the insidious stomach bug… Read More
