Which is Not a Way That Antigen-Antibody Complexes May Cause

Question

Which is not a way that antigen-antibody complexes may cause elimination of the antigen?
A) opsonization
B) enhancing phagocytosis
C) activation of complement
D) neutralization
E) sensitization

Accepted Answer

Sensitization is not a way that antigen-antibody complexes may cause elimination of the antigen. Sensitization refers to the process by which an individual becomes hypersensitive to an antigen after prior exposure to it, with subsequent exposure leading to an exaggerated immune response. The other options, opsonization, enhancing phagocytosis, activation of complement, and neutralization, all involve specific mechanisms by which antigen-antibody complexes may lead to the elimination of antigens.
