Question

Which of the following is incorrect regarding T-cells?

• A. These play important role in cell mediated immunity.
• B. These play an important role in activation of B-lymphocytes.
• C. These are a type of lymphocytes.
• D. These are not responsible for graft rejection.

Answer 1

Answer: (D)

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. The body is able to differentiate ‘self ’ and ‘non-self’ and the cell-mediated immune response is responsible for graft rejection.
