Dictionary » E » Endocytosis




A process in which cell takes in materials from the outside by engulfing and fusing them with its plasma membrane.


Most of the extracellular materials that the cells absorb are large polar molecules (e.g. proteins and hormones) that cannot pass through the hydrophobic plasma membrane by simple diffusion.

There are two types of endocytosis, called phagocytosis, which literally means cell-eating, and pinocytosis, which literally means cell-drinking.

Word origin: endo: G., comb. form of éndon: within + cyte: G. kutos, hollow vessel + -osis: expressing state or condition.
Related forms: endocytotic (adjective), endocytic (adjective).
Related phrases: trans-endocytosis.
Compare: exocytosis.
See also: plasma membrane.

Re: Multicellular prokaryote

... are related to that and to each other: endomembrane system, membrane bound organelles, sexual reproduction (associated with diploid or more), and endocytosis. Quite literally, eukaryotic cells in their own right are thought to have been formed from more than one cell (likely other organisms or ...

cellular mechanisms that result in symptoms of cholera

... while the A2 chain fits into the central pore of the B subunit ring. Upon binding, the complex is taken into the cell via receptor-mediated endocytosis. Once inside the cell, the disulfide bond is reduced, and the A1 subunit is freed to bind with a human partner protein called ADP-ribosylation ...

Protein expression but no mRNA

... The leukemia I work on is characterized by a SLOW progression only partly due to proliferation and even more due to inhibited apoptosis. Is endocytosis a completely unthinkable (and maybe stupid) suggestion?

looking for dyes that won't stain cells

Hi all, I'm looking for a recommendation: I need a cheap fluorescent dye that won't stain any part of my NIH-3T3 cells(a little endocytosis is OK) but is also soluble in water. So basically, rhodamine/fluorescein won't work because they do tend to get through the membrane of unhealthy ...
