Quizplus · Accepted Answer

Organ transplantation patients are at risk for type IV hypersensitivity reactions, also known as delayed-type hypersensitivity reactions, which occur when T cells react to foreign antigens on transplanted tissue and initiate an inflammatory response. This can lead to rejection of the transplanted organ. Type I, II, and III hypersensitivity reactions are not directly involved in rejection of transplanted tissue.
