  2. Endocytosis - Wikipedia

    en.wikipedia.org/wiki/Endocytosis

    Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane , which then buds off inside the cell to form a vesicle containing the ingested materials.

  3. Receptor-mediated endocytosis - Wikipedia

    en.wikipedia.org/wiki/Receptor-mediated_endocytosis

    Receptor-mediated endocytosis (RME), also called clathrin-mediated endocytosis, is a process by which cells absorb metabolites, hormones, proteins – and in some cases viruses – by the inward budding of the plasma membrane (invagination).

  4. Endosome - Wikipedia

    en.wikipedia.org/wiki/Endosome

    Molecules can be internalized via receptor-mediated endocytosis in clathrin-coated vesicles. Other types of vesicles also form at the plasma membrane for this pathway, including ones utilising caveolin.

  5. Trans-endocytosis - Wikipedia

    en.wikipedia.org/wiki/Trans-endocytosis

    Trans-endocytosis is the biological process where material created in one cell undergoes endocytosis (enters) into another cell. If the material is large enough, this can be observed using an electron microscope. [1] Trans-endocytosis from neurons to glia has been observed using time-lapse microscopy. [2] Trans-endocytosis also applies to ...

  6. 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 ...

  7. Clathrin-independent endocytosis - Wikipedia

    en.wikipedia.org/wiki/Clathrin-independent...

    Caveolar dynamin-dependent endocytosis relies of caveolae, which are invaginations of the cell plasma membrane made up of GPI-anchored proteins, sphingolipids, and cholesterol. [2] A part of the cavin family, caleoles provide integral structure for the cell membrane and associates with lipids, such as cholesterol, and PIP2 to form lipid ...

  8. Transcytosis - Wikipedia

    en.wikipedia.org/wiki/Transcytosis

    Transcytosis can be receptor-mediated and consists of three steps: 1) receptor-mediated endocytosis of the molecule on one side of the cell, e.g. the luminal side; 2) movement of the molecule through the intracellular compartment typically within the endosomal system; and 3) exocytosis of the molecule to the extracellular space on the other ...

  9. Potocytosis - Wikipedia

    en.wikipedia.org/wiki/Potocytosis

    Potocytosis is a type of receptor-mediated endocytosis in which small molecules are transported across the plasma membrane of a cell.The molecules are transported by caveolae (rather than clathrin-coated vesicles) and are deposited directly into the cytosol.
