Delayed-type cell-mediated hypersensitivity is also called type IV hypersensitivity. It is a T cell-mediated immune response that occurs 24-72 hours after exposure to an antigen. It is characterized by the recruitment of inflammatory cells to the site of antigenic stimulation and the activation of macrophages and T lymphocytes. It is involved in the pathogenesis of several autoimmune diseases, including multiple sclerosis, rheumatoid arthritis, and type 1 diabetes.
