Canadian immunologists have identified a mechanism that promotes the activation of T cell receptors by altering how one of its components interacts with the cell membrane.
More than 600,000 people worldwide have fallen victim to the lung disease COVID-19 so far, which is caused by the SARS coronavirus-2 (SARS-CoV-2). In order to obtain an effective therapy for COVID-19 as quickly as possible, ...

(Medical Xpress)—Neuroscience typically proceeds by trimming back previous overly dogmatic statements. Such is the case with new findings that proteins are locally manufactured to order throughout an extended neuronal tree. ...
Movement of secretory molecules, such as hormones and digestive enzymes, out of the cell is known as exocytosis. This process is guided by SNARE proteins, which help the fusion of secretory vesicles with the plasma membrane. ...

The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment.
It is a semipermeable lipid bilayer found in all cells. It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes such as cell adhesion, ion channel conductance and cell signaling. The plasma membrane also serves as the attachment point for both the intracellular cytoskeleton and, if present, the extracellular cell wall.
