Quizplus · Accepted Answer

Myasthenia gravis is an autoimmune disease where autoantibodies bind to and inactivate acetylcholine receptors at neuromuscular junctions, leading to muscle weakness. This is an example of a type II hypersensitivity reaction, where antibodies target self-antigens on the body's own cells. Anaphylaxis (A) is a type I hypersensitivity reaction involving IgE antibodies and immediate allergic reactions. Post-streptococcal glomerulonephritis (C) is a type III hypersensitivity reaction where immune complexes form and deposit in the kidneys, leading to inflammation and damage. Bruton's agammaglobulinemia (D) is a primary immunodeficiency where individuals have insufficient levels of antibodies and are unable to mount an effective immune response against infections.
