What could result when grafted tissue such as bone marrow contains passenger lymphocytes?

Question

Quizplus · Accepted Answer

Graft versus host disease (GVHD) can occur when transplanted tissue such as bone marrow contains passenger lymphocytes that recognize the recipient's tissues as foreign and attack them. This can cause a range of symptoms, including skin rashes, gastrointestinal problems, and liver damage. Host rejection of the graft can occur if the recipient's immune system recognizes the transplanted tissue as foreign and mounts an immune response against it, but this is not specifically related to the presence of passenger lymphocytes. Formation of autoantibodies and hypogammaglobulinemia are not typically associated with grafts containing passenger lymphocytes.
