Microscopy trifecta examines how cells engulf nutrients, viruses
Scientists have a better understanding of a mechanism that allows cells to internalize beneficial nutrients and not-so-beneficial viruses, thanks to collaboration among researchers from two South Dakota universities and the National Institutes of Health. South Dakota State University associate professor Adam Hoppe, South Dakota School of Mines & Technology professor Steve Smith and NIH scientists Justin Taraska and Kem Sochacki combined three unique types of microscopy to track how a protein called clathrin triggers cell membrane bending. They found that clathrin, which creates a honeycomb shaped scaffold on the cell membrane, has an unexpected amount of plasticity when pinching off small portions of the cell membrane.
