Microbiology Analysis Argumentative Essay Example

Type 2 Hypersensitivity also known as Cytotoxic

Hypersensitivity is where the antibodies are produced by the immune response. These antibodies then begin to bind to antigens on the patients own cell surface. Once these are binded they are recognized as intrinsic or extrinsic. During this phase the cells can act as antigen presenting cells. Another form of Type 2 hypersensitivity is called antibody-dependent cell-mediated cytotoxicity. (The reactions ran can take hours to a day.) Type 4 hypersensitivity which is an independent antibody and its reactions take 2 to 3 days.

Unlike others, Type 4 hypersensitivity is not antibody mediated but is a type of cell mediated response. 6. Explain what monoclonal antibody technology is. -Monoclonal technology is a way to produce large quantities of pure antibodies. Our body releases these proteins to help fight off or counteract the effects of these antigens.

When cells are combined, such as a mammalian cell and a tumor cell, it is called hybridoma. When these cells are joined a large amount of pure antibodies are produced. These monoclonal antibodies only fight molecules with little or no side effects.

Hybridoma cells are also referred to as a fused hybrid cell because they are able to grow indefinitely in the media. 7. Explain how your immune system avoids a primary immune response to your antigens.

The antigens we have in our body are marked with MHCs. When our immune system recognizes a cell with a MHC marker it does not get attacked. Cells that are not marked with this MHC marker get attacked. Immune memory allows the antibodies to remain in circulation and mark it so that

it will remember it during its next exposure in the future.
