- n. Introduction of fluids into a cell by invagination of the cell membrane, followed by formation of vesicles within the cells.
- n. biology A form of endocytosis in which material enters a cell through its membrane and is incorporated in vesicles for digestion
- n. process by which certain cells can engulf and incorporate droplets of fluid
- Greek pīnein, to drink; see pō(i)- in Indo-European roots + cyt(o)- + -osis. (American Heritage® Dictionary of the English Language, Fourth Edition)
“The primary types of specialized transport mechanisms are: facilitated diffusion; active transport; and endocytosis (phagocytosis and pinocytosis).”
“The two main forms of endocytosis are phagocytosis and pinocytosis.”
“The same is true for pinocytosis (the "drinking" of organic substances) and the release of wastes that are contained in contractile vacuoles.”
“I don't think any cell in the body can take us in by pinocytosis or by any other means.”
“The researchers developed a way to co-opt pinocytosis, the process by which cells drink in small amounts of surrounding fluid.”
“Following adsorption, the rabies cell breaks through the host's cell and uses pinocytosis to enter into the host's cytoplasm.”
“In addition, low relative molecular mass proteins (less than 60,000Da), as well as low concentrations of albumin, that were able to penetrate the layers in the renal corpuscle are removed by pinocytosis, followed by degradation by hydrolytic enzymes in lysosomes.”
“Baba T, van der Bliek AM, Schmid SL (1995) Clathrin-independent pinocytosis is induced in cells overexpressing a temperature-sensitive mutant of dynamin.”
“Berlin RD, Davis BH (1984) Use of horseradish peroxidase and fluorescent dextrans to study fluid pinocytosis in leukocytes.”
“Two ways out of this problem: a) the first plasma membrane was not closed at all but also semi open and could only be closed after the evolution of aselective pores, b) the closing of the membrane happened concomitant with the generation when vesicles that bud off the ER contained already channels or the vesicle trafficking served as pinocytosis and waste disposal.”
