Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...

Membrane proteins are responsible for transporting chemicals and messages between a cell and its environment. But determining their structure has proved challenging for scientists. A study by UC Santa ...

Structure of the cell membrane and conceptual diagrams of (a) short-range viscosity and (b) long-range viscosity. (a) Random thermal motion of lipids on a nanometer scale is not impeded by proteins or ...

Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used ...

In silico antibody accessibility analysis indicates that ectodomain epitopes are transiently exposed, while MPER epitopes are virtually always occluded in the pre-fusion trimer.
