What is the mechanism of hypersensitivity type III and its relation to immunocomplexes?
Immunocomplexes are formed by the combination of antibodies with antigens.
Immunocomplexes can trigger a severe inflammation when deposited in large quantities in tissues, classified as hypersensitivity type III.
The deposition of immunocomplexes in the lungs after inhaling antigenic dust causes hypersensitivity pneumonia.
Hypersensitivity type III is an aspect of many viral diseases, especially if the virus is not neutralized by antibodies and large amounts of immunocomplexes are generated as a result.
The intensity and importance of hypersensitivity type III reactions depend on the quantity and site of immunocomplex deposition.
a) I, II, III, IV and V are correct.
b) I, II, III and IV are correct.
c) II, III, IV and V are correct.
d) I, III, IV and V are correct.

O mecanismo de hipersensibilidade tipo III está relacionado à formação de imunocomplexos. Os imunocomplexos são formados pela combinação de anticorpos com antígenos. Quando depositados em grandes quantidades nos tecidos, podem desencadear uma inflamação grave, classificada como hipersensibilidade tipo III. A deposição de imunocomplexos nos pulmões após inalação de poeira antigênica causa pneumonia de hipersensibilidade. A intensidade e importância das reações de hipersensibilidade tipo III dependem da quantidade e localização da deposição de imunocomplexos. A alternativa correta é a letra d) I, III, IV e V estão corretas.
