Transplantation of tissues/ organs fails often due to non-acceptance by the patient's body. Which type of immune response is responsible for such rejections ?
- Cell-mediated immune response
- Physiological immune response
- Hormonal immune response
- Autoimmune response
Answer
(1) Cell-mediated immune response
Solution
As per NCERT, the body is able to differentiate 'self' and 'nonself', and the cell-mediated immune response (mediated by T-lymphocytes) is responsible for graft rejection.
∴ Rejection of transplanted tissues/organs is due to cell-mediated immune response.
