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?
  1. Autoimmune response
  2. Cell-mediated immune response
  3. Hormonal immune response
  4. Physiological immune response

Solution

Non-acceptance or rejection of graft or transplanted tissues/organs is due to cell-mediated immune response. Cell-mediated immunity is defined as a beneficial host response characterized by an expanded population of specific T-cells, which, in the presence of antigens, produce cytokines locally.
