  2. Endocytosis - Wikipedia

    en.wikipedia.org/wiki/Endocytosis

    Potocytosis is a form of receptor-mediated endocytosis that uses caveolae vesicles to bring molecules of various sizes into the cell. Unlike most endocytosis that uses caveolae to deliver contents of vesicles to lysosomes or other organelles, material endocytosed via potocytosis is released into the cytosol. [8]

  3. Cytosis - Wikipedia

    en.wikipedia.org/wiki/Cytosis

    Mechanism of clathrin-dependent endocytosis. Clathrin-coated pits in endocytosis: The membrane of the cell invaginates using the protein clathrin. The clathrin uses actin to pull together the sides of the plasma membrane and form a vesicle inside the cellular cytosol. Receptor-mediated endocytosis Receptor-mediated endocytosis is a mode of ...

  4. RAB7A - Wikipedia

    en.wikipedia.org/wiki/RAB7A

    Ras-related protein Rab-7a is involved in endocytosis, which is a process that brings substances into a cell. The process of endocytosis works by folding the cell membrane around a substance outside of the cell (for example a protein) and then forms a vesicle. The vesicle is then brought into the cell and cleaved from the cell membrane.

  5. Intracellular transport - Wikipedia

    en.wikipedia.org/wiki/Intracellular_transport

    One very well understood form of intracellular transport is known as endocytosis. Endocytosis is defined as the uptake of material by the invagination of the plasma membrane. [ 4 ] More specifically, eukaryotic cells use endocytosis of the uptake of nutrients, down regulation of growth factor receptors’ and as a mass regulator of the ...

  6. Potocytosis - Wikipedia

    en.wikipedia.org/wiki/Potocytosis

    The molecules are transported by caveolae (rather than clathrin-coated vesicles) and are deposited directly into the cytosol. [1] Like other types of receptor-mediated endocytosis, potocytosis typically begins when an extracellular ligand binds to a receptor protein on the surface of a cell, thus beginning the formation of an endocytotic vesicle.

  7. Endosome - Wikipedia

    en.wikipedia.org/wiki/Endosome

    These lipids on the surface of the endosomes help in the specific recruitment of proteins from the cytosol, thus providing them an identity. The inter-conversion of these lipids is a result of the concerted action of phosphoinositide kinases and phosphatases that are strategically localized [17]

  8. Endomembrane system - Wikipedia

    en.wikipedia.org/wiki/Endomembrane_system

    The pH of vacuoles enables them to perform homeostatic procedures in the cell. For example, when the pH in the cells environment drops, the H + ions surging into the cytosol can be transferred to a vacuole in order to keep the cytosol's pH constant. [33] In animals, vacuoles serve in exocytosis and endocytosis processes. Endocytosis refers to ...

  9. Viral entry - Wikipedia

    en.wikipedia.org/wiki/Viral_entry

    Viral entry via endocytosis. Viruses with no viral envelope enter the cell generally through endocytosis; they “trick” the host cell to ingest the virions through the cell membrane. Cells can take in resources from the environment outside of the cell, and these mechanisms may be exploited by viruses to enter a cell in the same manner as ...
