The activity of several signalling receptor families is modulated by their endocytosis from the cell surface. Internalization of receptors can not only attenuate further response of receptors to ...

All cells have surface membranes and maintaining the surface area of this membrane is critical to the normal functioning of cells. The surface membranes of cells lining our lungs, guts and the ...

Dynamin is a protein that plays a central role in endocytosis—the process where cells internalize substances by wrapping them in cell membrane vesicles. For a vesicle to detach, the neck of the ...

Each cell is separated from its environment by a membrane that protects the cell from the outside environment. However, this barrier can be overcome by certain chemicals that sustain the basic ...

Living cells and tissues show a high capacity to absorb various chemical compounds from the surrounding environment. Although the absorption of small molecules is quite simple for cells and tissues, ...

To survive and fulfill their biological functions, cells need to take in material from their environment. In this process, proteins within the cell pull inward on its membrane, forming a pit that ...

Technique instantly delivers controlled doses directly into cytosol with no reliance on endocytosis or effects on cell viability, the team reports. Scientists report on the development of a ...

All cells have surface membranes, and this membrane is especially important in the light-sensitive cells of the eyes in your body. Within your eyes are millions of photoreceptors - nerve cells that ...
