Answer:
The type of hypersensitivity reaction where soluble circulating immune complexes form and induce the hypersensitivity reaction is Type III hypersensitivity reaction.
Step-by-step explanation:
Here's an explanation:
1. Type III hypersensitivity: Type III hypersensitivity reactions occur when there is an excessive formation of immune complexes in the body. Immune complexes are formed when antigens (foreign substances) bind to antibodies (IgM or IgG) in the bloodstream.
2. Formation of immune complexes: In Type III hypersensitivity reactions, soluble circulating immune complexes are formed when there is an excess of antigens and antibodies in the bloodstream. These immune complexes can circulate throughout the body and deposit in various tissues and organs.
3. Induction of the hypersensitivity reaction: The deposition of immune complexes triggers an inflammatory response in the tissues where they are deposited. This inflammation can lead to tissue damage and the development of symptoms associated with the hypersensitivity reaction.
4. Examples: Type III hypersensitivity reactions are involved in various autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis, and immune complex-mediated vasculitis. In these conditions, the formation of immune complexes plays a significant role in the development of symptoms and tissue damage.
In summary, Type III hypersensitivity reactions involve the formation of soluble circulating immune complexes that can deposit in tissues and induce an inflammatory response. This type of reaction is associated with autoimmune diseases and immune complex-mediated vasculitis.
