Which type of hypersensitivity reaction involves autoantibodies causing tissue injury?
Understand the Problem
The question is asking about the classification of hypersensitivity reactions, specifically which type involves autoantibodies that cause damage to tissues. The response will require understanding the various types of hypersensitivity reactions in immunology.
Answer
Type II hypersensitivity reaction.
The final answer is type II hypersensitivity reaction.
Answer for screen readers
The final answer is type II hypersensitivity reaction.
More Information
Type II hypersensitivity reactions involve antibodies binding to cell surface antigens, leading to cell injury or destruction. This process is mediated by IgG and IgM antibodies.
Tips
A common mistake is confusing type II and type III hypersensitivity reactions. Type II involves autoantibodies binding to cell surface antigens directly, while type III involves immune complexes formed with soluble antigens.
