Complement triggers all the following immune functions except:
1. | Phagocytosis | 2. | Inflammation |
3. | Membrane attack | 4. | Anamnestic response |
1. | Circulating monocyte | 2. | Natural Killer cell |
3. | Mast cell | 4. | Goblet cell |
CD4 proteins on a helper T cell are non-functional. In such a situation, these T helper cells will not be able to:
1. | lyse tumor cells. |
2. | stimulate a cytotoxic T cell. |
3. | interact with a class I MHC-antigen complex. |
4. | interact with a class II MHC-antigen complex. |
Consider the given two statements:
I: | Inflammation and infection are not synonyms. |
II: | Inflammations, in many cases, may not be driven by microbial invasion. |
1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. I is correct and II is incorrect.
4. Both I and II are incorrect.
The cells responsible for humoral adaptive immune responses proliferate and differentiate into plasma cells in the:
1. | liver | 2. | bloodstream |
3. | lymph nodes | 4. | red pulp of the spleen |
The class of antibodies involved in allergic response is:
1. | IgA | 2. | IgG |
3. | IgE | 4. | IgM |
CD8+ T cells, also known as "killer cells", are cytotoxic which means that:
1. | they determine if and how other parts of the immune system respond to a specific, perceived threat. |
2. | they are able to directly kill virus-infected cells as well as cancer cells. |
3. | they differentiate plasma cells that release chemicals to kill cancer cells. |
4. | provide the critical mechanism of tolerance. |
Antigen presentation is a process by which the innate immune system:
1. | Recruits immune cells to sites of infection |
2. | Activates the complement cascade |
3. | Activates the adaptive immune system |
4. | Acts as a physical and chemical barrier to infectious agents |
1. | H5N1 | 2. | H1L1 |
3. | H2L2 | 4. | H1N1 |
1. | CT | Computed Tomography |
2. | MRI | Magnetic Radiation Imaging |
3. | NACO | National AIDS Control Organization |
4. | MALT | Mucosa Associated Lymphoid Tissue |
