Grafted kidney ay be rejected in a patient due to: A Humoral immune response B Cell-mediated immune response C Passive immune response D Innate immune response
Correct option is B) The grafted kidney may be rejected in a patient due to the cell-mediated immune response that is mediated by T-lymphocytes. The body is able to differentiate 'self' and 'non-self'. Therefore, tissue matching, blood group matching are essential before undertaking any graft/transplant and even after this the patient has to take immunosuppressants all his/her life. Hence, the Grafted kidney may be rejected in a patient due to Cell-mediated immune response. So, the correct answer is 'Cell-mediated immune response'.
