Question

Quizplus · Accepted Answer

An immune complex is formed when an antibody binds to an antigen, forming a complex. This complex can then bind to complement proteins, leading to inflammation and tissue damage. Option A is incorrect because antigen cannot bind to itself. Option C is incorrect because an immune complex involves the binding of an antibody to an antigen, not another antibody. Option D is incorrect because LPS (lipopolysaccharide) is not directly involved in the formation of immune complexes.
