Question

Quizplus · Accepted Answer

Glomerulonephritis is a type III hypersensitivity reaction, also known as immune complex hypersensitivity. In this type of reaction, circulating antigen-antibody complexes deposit in various tissues, including the glomeruli of the kidneys, leading to inflammation and subsequent damage. Streptococcal antigens can lead to the formation of immune complexes, which in turn can trigger an immune response and glomerulonephritis.
