  • What is type II hypersensitivity? Type II hypersensitivity is an immune response in which host cells are damaged due to antibodies binding to the cell surface. Find our full video library only on Osmosis: osms.it/more.

    just a summary...so i can come back and revise too
    Type 2 hypersensitivity
    mechanism of action:
    1.Activation of complement system: C1 binds to Fc portion of the antibody. Activated C3,C4,C5 - atrracts neutrophils, degranulation, cell lysis.
    2. Membrane Attack complex - disturbance in osmotic gradient - cell lysis
    3.C3 associated opsonization and phagocytosis
    4. ADCC - antibody dependent cellmediated toxicity - NK cells
    NONCYTOTOXIC MECHANISM: Antibody mediated cellular dysfunction.
    eg..Graves disease, myasthenia gravis.

    • @joshuarandall6041
      @joshuarandall6041 6 лет назад +2

      Osmosis is the diffusion of water. Diffusion is the diffusion of solutes. They both flow from high to low concentrations, which means they often flow in opposite directions from one another. The water will flow into the cell, whereas the solutes will flow out of the cell for example, all in the process of equalizing concentration gradients.

    You guys are great, I have a friend of mine that is always recommending you to me and here I am, listening to his advice. Just wanted to drop this comment about 3:00, the complement proteins (C1q) does not bind to the Fc portion of the antibody, rather it bind to the antigen binding side which is found on the constant region of IgG and it is above and different than the Fc portion.

    • @osmosis
      @osmosis  7 лет назад

      Can you share with us a credible source that supports the correction? Thanks!

    • @AhmedEkri
      @AhmedEkri 7 лет назад +1

      Hello, I just double checked from many journals articles, what you have said is true. The Fc portion on an IgG is divided into two compartments, upper one for complement and lower one for membranes or receptors. Thanks for your reply.

    but in case of myasthenia gravis I looked into different sources and I found that actually the complement system is activated when the anti-AChr is attached to the AChR and it leads to decline in numbers of AChR
