Type III hypersensitivities are also referred to as immune complex mediated hypersensitivities.
Which cell is responsible for clearing the antibody-antigen complexes that are formed? In type I
hypersensitivity, prior sensitization to the antigen/allergen is not required because it\'s an
immediate type of reaction. True False Which cell types participate in antibody mediated
attacks of either cells or red blood cells in type II hypersensitivities?
Solution
Hypersensitive is the group of unfavourable reactions produced by the normal Immune system. It
includes allergies and Autoimmunity. Type-III immunity is immune complex mediated diseases
that include Serum sickness, Rheumatoid arthritis etc. The mediators are IgG, complement and
Neutrophills.
7. Answer is Macrophages.
8. False: Prior sensitization with allergin, leads to IgE production, then they bind to mast cells.
Again encounter wits same allergin, bind to these mast cell bound IgE. Finally leads to
degranulation and Type-1 hypersensitivity.
9. All three types of cells: Macrophages, NK cells and Neutrophils.
