Question

Quizplus · Accepted Answer

Type IV hypersensitivity, also known as delayed-type hypersensitivity (DTH), involves cell-mediated immune reactions that typically require 24-72 hours to develop. This response is mediated by T cells and is characterized by inflammation and tissue damage resulting from the release of cytokines and toxic molecules, rather than the direct action of antibodies. Examples include contact dermatitis, tuberculin (skin) test reactions, and some autoimmune diseases.
