Question

Which of the following are the three mechanisms by which antibody-antigen complexes trigger antigen destruction?

विकल्प

• Cell lysis, inflammation, and fever

• Agglutination, precipitation, and denaturation

• Direct neutralisation, opsonisation, and complement activation

• Phagocytosis, apoptosis, and necrosis

Answer 1

When antibodies bind to antigens forming a complex, antigen destruction is triggered through three specific mechanisms: direct neutralisation (directly disabling the antigen), opsonisation (marking for phagocytosis), and complement activation (triggering the complement cascade).
