  1. Opsonin - Wikipedia

    • Subsequent research found two main types of opsonin in blood that opsonised bacteria: complement proteins [4] and antibodies. [5] However, there are now known to be at least 50 proteins that act as opsonins for pathogens or other targets. See more

    Overview

    Opsonins are extracellular proteins that, when bound to substances or cells, induce phagocytes to … See more

    Mechanisms

    Opsonins induce phagocytosis of targets by binding the targets (e.g. bacteria) and then also binding phagocytic receptors on phagocytes. Thus, opsonins act as bridging molecules between the target and the phagocyte, … See more

    Types

    Opsonins are related to the two types of immune systems: the adaptive immune system and the innate immune system.
    Antibodies are synthesized by B cells and are secreted in response to recognition of specific ant… See more

    Targets

    A number of opsonins play a role in marking apoptotic cells for phagocytosis without a pro-inflammatory response.
    Members of the pentraxin family can bind to apoptotic cell membrane components like phosphatid… See more
