Which of the following reasons is mainly responsible for graft rejection in transplantation of organs?

  1. Cell-mediated response
  2. Inability of recipient to differentiate between ‘self’ and ‘non-self’ tissues/cells
  3. Humoral immune response only
  4. Auto-immune response

Answer

(1) Cell-mediated response

Solution

As per NCERT, the body is able to differentiate between ‘self’ and ‘non-self’, and the cell-mediated immune response (by T-lymphocytes) is responsible for graft rejection.

⇒ The rejection occurs precisely because the recipient recognises the graft as ‘non-self’.

⇒ It is neither a humoral response only nor an auto-immune response (attack on self cells).
