Quizplus · Accepted Answer

Graft versus host disease (GVHD) can occur when passenger lymphocytes from the donor tissue recognize the recipient's tissue as foreign and attack it. This can lead to severe immune reactions which include damage to organs, skin rashes, and gastrointestinal symptoms. This is a potentially life-threatening condition and needs to be managed with immunosuppressive therapy.
