Endocytosis (from Greek endon, meaning within and kytos, meaning vessel) is the process by which materials are engulfed into a cell. There is an infolding of the cell membrane, which then pinches around substances, forming a vacuole or vesicle, and the...

The process whereby a CELL can use a portion of its MEMBRANE to envelope a large MOLECULE or particles of a complex substance and draw it into itself, by cutting of that part of the membrane to form an intracellular VESICLE; PINOCYTOSIS describes this...

Endocytosis is a process whereby cells absorb material (molecules such as proteins) from the outside by engulfing it with their cell membrane. It is used by all cells of the body because most substances important to them are large polar molecules, and...

Endocytosis is the internalization of plasma membrane proteins and lipids, extracellular molecules, fluids, particles, exosomes, viruses, and bacteria. Endocytic internalization is a conserved process for all eukaryotic cells that is required for diverse cellular functions. These include turnover and degradation of plasma membrane proteins...

ABSTRACT Infection by membrane-enveloped viruses requires the binding of receptors on the target cell membrane to glycoproteins, or "spikes," on the viral membrane. The initial entry mechanism is usually classified as fusogenic or endocytotic. However, binding of viral spikes to cell surface receptors...
