immune cells from a transplant attack the recipient's tissues
Graft-versus-host disease (GVHD) is a medical condition that can occur after a bone marrow or stem cell transplant, where the donated immune cells (the graft) attack the recipient's (the host's) body tissues. This happens because the donor's immune cells recognize the recipient's cells as foreign and mount an immune response against them, potentially causing damage to organs such as the skin, liver, and intestines.
