Delayed hypersensitivity is also known as type IV hypersensitivity. This type of hypersensitivity involves activation of T cells, which then release cytokines and recruit other cells to the site of antigen exposure. The reaction typically takes several days to develop, hence the term "delayed." Examples of type IV hypersensitivity include contact dermatitis and tuberculin skin tests. It is important to note that delayed hypersensitivity is different from immediate hypersensitivity (type I), which involves the activation of IgE antibodies and can result in anaphylaxis.
