Which of the following is not a cellular barrier?

1. PMNL

2. Monocytes

3. Macrophages

4. Virus infected cells

Anamnestic Response is generated by

1. First interaction of pathogen with the body

2. Second interaction of pathogen with the body

3. Response against self cells

4. Response against not a potential antigen

The B lymphocytes produce an army of proteins in response to pathogens into our body to fight with them and T lymphocytes help B lymphocytes to produce that army.

And such proteins are known as

1. Cytokines

2. Interferons

3. Antibodies

4. Allergen

The response generated by antibodies is called

1. Cell mediated Immune response

2. Humoral immune response

3. Primary immune response

4. Anamnestic immune response

During transplantation, which immunity causes rejection?

1. Humoral immunity

2. CMI

3. Innate immunity

4. Anibody mediated immunity

In the structure of an antibody; which terminal has antigen binding site?

1. N

2. C

3. N terminal of heavy chain and C terminal of light chain

4. C terminal of heavy chain and N terminal of light chain

IgM is pentamerous and weight of heavy chain is 1000000 Da and that of light chain is approximately half of the heavy chain, then find the weight of IgM.

1. More than 1500kDa

2. 150kDa

3. 15 kDa

4. 300 kDa

If a person X contracts a disease successfully, which kind of immunity has he developed?

1. Active

2. Passive

3. Anamnestic

4. Humoral

1. Natural

2. Passive

3. Active

4. More than one option

When quick immune response is required, we administer which kind of immunization?
