Detailed explanation-1: -Type II hypersensitivity is also known as cytotoxic reactions and engages IgG and IgM antibodies, leading to the complement system activation and cell damage or lysis. Type III hypersensitivity is also known as immune complex reactions and involves IgG, IgM, and sometimes IgA antibodies.
Detailed explanation-2: -There are four different types of hypersensitivities, and the second type or type II hypersensitivity is sometimes called cytotoxic hypersensitivity because a lot of disorders caused by this hypersensitivity involve antibody mediated destruction of healthy cells.
Detailed explanation-3: -The difference between a normal infectious immune response and a type 1 hypersensitivity response is that in type 1 hypersensitivity, the antibody is IgE instead of IgA, IgG, or IgM.
