Cellular membrane proteins play many important roles throughout the body, including transporting substances in and out of the cell, transmitting signals, speeding up reactions and helping neighboring ...

When the cell's recycling stations, the lysosomes, start leaking, it can become dangerous. Toxic waste risks spreading and ...

A look at cancer cells: Thanks to an innovative method of super-resolution microscopy, researchers observed with molecular resolution in 3D how therapeutic antibodies attack and alter B cells, thereby ...

Filopodia are specialized structures that extend from the cell membrane to allow a cell to explore the environment around it. These thin protrusions are full of a protein called actin, which, in ...

Schematic of an active cell membrane. In a typical active biological process, active proteins (shown in a variety of colors) in a cell membrane (shown in blue) interact with various biological ...

Inside cells, there exists an extensive system of canals known as the endoplasmic reticulum (ER), which consists of membrane-encased tubes that are partially broken down as needed -- for instance in ...

In blood cancers such as chronic lymphocytic leukemia, B cells of the immune system multiply uncontrollably. One form of therapy involves labeling the CD20 protein on the surface of the B cells with ...
