Which of the following statements is NOT a possible outcome of antigen-antibody reaction?
A)clonal deletion
B)activation of complement
C)opsonization
D)ADCC
E)agglutination

Question

Quizplus · Accepted Answer

Clonal deletion is not a direct outcome of antigen-antibody reaction. Clonal deletion refers to the elimination of self-reactive lymphocytes during immune system development, and is not related to the interaction between antigens and antibodies. The other choices are all possible outcomes of antigen-antibody reactions. B) Activation of complement refers to the series of events triggered when antibodies bind to antigens, resulting in the recruitment of several proteins that help to destroy the pathogen. C) Opsonization refers to the process by which antibodies or complement proteins bind to an antigen in order to facilitate phagocytosis by macrophages or neutrophils. D) ADCC (antibody-dependent cellular cytotoxicity) is the process by which antibodies bind to target cells and recruit immune cells, such as natural killer cells, to destroy the target. E) Agglutination refers to the clumping of particles, such as bacteria, resulting from the binding of antibodies to multiple antigens on the surface of each particle.
