Hypersensitivity: Type I hypersensitivity, Type III hypersensitivity & Type II hypersensitivity

Hypersensitivity (also called hypersensitivity reaction) is an immune response characterized by mechanisms that cause significant tissue damage or physiological dysfunction, whether directed against pathogens, harmless environmental antigens, or self-antigens that is reproducible upon re-exposure to the antigen. While hypersensitivity mechanisms can…
