  2. Phagocytosis - Wikipedia

    en.wikipedia.org/wiki/Phagocytosis

    Phagocytosis (from Ancient Greek φαγεῖν (phagein) 'to eat' and κύτος (kytos) 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome. It is one type of endocytosis. A cell that performs phagocytosis is called a phagocyte.

  4. Intracellular digestion - Wikipedia

    en.wikipedia.org/wiki/Intracellular_digestion

    Amoeba uses pseudopodia to capture food for nutrition in a process called phagocytosis. Paramecium. Paramecium uses cilia in the oral groove to bring food into the mouth pore which goes to the gullet. At the end of the gullet, a food vacuole forms. Undigested food is carried to the anal pore. Euglena

  5. Endocytosis - Wikipedia

    en.wikipedia.org/wiki/Endocytosis

    From left to right: Phagocytosis, Pinocytosis, Receptor-mediated 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 ...

    Phagocytosis in Three Steps Macrophages, neutrophils, and dendritic cells are all cells of the innate immune system that utilize phagocytosis and are equipped with Toll-like receptors (TLR) . Toll-like receptors are present on each of these cells and recognize a variety of microbial products resulting in the induction of more specific immune ...

  7. Phagosome - Wikipedia

    en.wikipedia.org/wiki/Phagosome

    Phagocytosis of a bacterium, showing the formation of phagosome and phagolysosome In cell biology , a phagosome is a vesicle formed around a particle engulfed by a phagocyte via phagocytosis . Professional phagocytes include macrophages , neutrophils , and dendritic cells (DCs).

  8. Classical complement pathway - Wikipedia

    en.wikipedia.org/wiki/Classical_complement_pathway

    The cleaved products attract phagocytes to the site of infection and tags target cells for elimination by phagocytosis. In addition, the C5 convertase initiates the terminal phase of the complement system, leading to the assembly of the membrane attack complex . The membrane attack complex creates a pore on the target cell's membrane, inducing ...

  9. Receptor-mediated endocytosis - Wikipedia

    en.wikipedia.org/wiki/Receptor-mediated_endocytosis

    Mechanism of clathrin-dependent 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).
