Cellular membranes are maintained as closed compartments, broken up only transiently during membrane reorganization or lipid transportation. However, open-ended membranes, likely derived from scissions of the endoplasmic reticulum, persist in vaccinia virus-infected cells during the assembly of the viral envelope. A group of viral membrane assembly proteins (VMAPs) were identified…

A first look at interstitial fluid flow in the brain
Past research has shown a link between interstitial fluid flow and an increased invasion rate of glioblastoma cells, and biomedical researchers and electrical engineers recently developed a new method to measure and reconstruct interstitial fluid flow velocities in the brain. This method gives a first look at interstitial fluid flow dynamics in glioma models, and the technique can readily translat

In Memoriam: Nobel Laureate Arvid Carlsson, a Pioneer in Parkinson’s Treatment
Photo: Johan Wingborg/University of Gothenburg We regret to announce the loss of Dana Alliance member Arvid Carlsson , M.D., Ph.D., who passed away last Friday at 95 years old. Carlsson laid the groundwork for the treatment of Parkinson’s disease by discovering dopamine is a neurotransmitter that plays an important role in motor function. In 2000, this research won him the Nobel Prize in Physiolo
