Transplantation of tissues/organs to some patients often fails due to rejection by the body of the patient. Which type of immune response is responsible for such rejections?
Show Hint
Transplant rejection = T-cell (cell-mediated) immunity; not antibody-driven (humoral).

- Autoimmune response
- Humoral immune response
- Physiological immune response
- Cell mediated immune response
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Transplant rejection is mainly mediated by T-lymphocytes.
Step 2: These cells recognize the graft as foreign and attack it.
Step 3: This is part of the cell-mediated immune response, not humoral (which involves antibodies).
