HUMORAL IMMUNITY

 CELL MEDIATED IMMUNITY

1. It is mediated by B-lymphocytes.

2. Antibodies are produced in the blood in response to an antigen.

3. The onset is rapid.

1. It is mediated by T-lymphocytes.

2. T-cells help B-cells in producing Antibodies.T-cells secrete cytokines.

3. The onset is delayed.


b). A patient who has undergone organ transplant is put on immune-suppressants so as to prevent T- cells from recognizing the foreign tissue ( any organ that is transplanted like heart, kidney, liver etc.) and rejecting it and killing it. Thus to prevent host graft rejection the patient is put on immunosuppressants.
