1. Complement
2. Interferon
3. Interleukin
4. Pyrogen
Grafted kidney may be rejected in a patient due to?
| 1. | Humanol immune response |
| 2. | Cell-mediated immune response |
| 3. | Passive immune response |
| 4. | Innate immune response |
The type of immunity responsible for graft rejection is:
| 1. | Humoral immunity | 2. | Cell mediated immunity |
| 3. | Innate immunity | 4. | Hyperimmunity |
| Assertion (A): | Any subsequent encounter with the same pathogen encountered earlier elicits a highly intensified secondary or anamnestic response. |
| Reason (R): | The body appears to have memory of the first or any previous encounters with the same antigen. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
| 1. | a secondary immune response |
| 2. | a more rapid response |
| 3. | a response mediated by dendritic cells |
| 4. | Both 1 and 2 options are correct |
Transplantation of tissues / organs fails often due to non-acceptance by the patient's body. Which type of immune –response is responsible for such rejection
| 1. | Autoimmune response |
| 2. | Cell- mediated immune response |
| 3. | Hormonal immune response |
| 4. | Physiological immune response |
| Assertion (A): | An antibody is represented as H2L2. |
| Reason (R): | An antibody molecule has two heavy chains and two light chains. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true, but (R) is not the correct explanation of (A). |
| 3. | (A) is true, but (R) is false. |
| 4. | (A) is false, but (R) is true. |
| Assertion (A): | A xenograft, a transplant of organs or tissue from one species to another, is often an extremely dangerous type of transplant. |
| Reason (R): | The chances of rejection of the graft by the immune system of the host are very high. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
