Piinoktoosi
Piinoktoosi, the Finnish term for pinocytosis, is a form of endocytosis in which a cell takes up extracellular fluid and dissolved solutes through small vesicles formed by inward folding of the plasma membrane. It is generally non-specific in the solutes it internalizes and is distinct from phagocytosis, which engulfs large particles.
Pinocytosis occurs via several routes. Macropinocytosis produces relatively large vesicles called macropinosomes and is driven by
Physiological roles include sampling of extracellular fluid and nutrients across many cell types. In the intestinal
Regulation and trafficking are energy-dependent and rely on the cytoskeleton. Vesicle formation and scission involve a
Clinical and research relevance includes the fact that some pathogens exploit pinocytic pathways to enter host
