If a person with a normally functioning immune system receives an organ transplant, which consequence follows relating to cellular rejection?

💡 Explanation

T-cell mediated graft destruction occurs because the recipient's T-cells recognize the transplanted organ's cells as foreign, triggering a cytotoxic immune response that destroys the graft. Therefore, T-cell activation causes rejection, rather than B-cell antibody production or NK cell hyperactivity, which play different roles in immune responses.
