Question 1

Is the adaptive immune system rarely malfunction

Answer 1

Wrong

Question 2

The acquired immunity is antigen dependent or independent

Answer 2

It is antigen dependant

Question 3

Tell me the function of the following
Interferons
Natural killer cells
T cytotoxic cells

Answer 3

Interferons prevent the virus replication and gives a protection against the virus
T cytotoxic cell kill virally infected cells (intercellular pathogen) and tumor represented with Mac1
NKC kill virally infected cells and cancer cells

Question 4

What do we mean by improvement with each response and to which immunity

Answer 4

To the adaptive immune responses and improvement in the responses and it is in the immunologic feature

Question 5

Tb bacteria cause bladder cancer and it’s treated by which vaccine and what is the mechanism and how it’s reached to the bladder

Answer 5

By BCG vaccine and that help in calling the macrophages for the tumor cells and it reaches the bladder by cystoscope mechanism

Question 6

When neutrophils occurs

Answer 6

Neutrophils is the increase in number of the phagocytic wbcs like neutrophils and macrophages
And that occurs in a bacterial infection

Question 7

When neutrophils occurs

Answer 7

Neutrophils is the increase in number of the phagocytic wbcs like neutrophils and macrophages
And that occurs in a bacterial infection

Question 8

When eosinophilia occur

Answer 8

It occurs in the parasite infection and in response to hypersensitivity type one (allergy)

Question 9

Mast cells role

Answer 9

Question 10

Mast cells are never seen in blood

Answer 10

True always stuck in the tissue

Question 11

What is the role of the gamma interferon

Answer 11

The role of it is to recruit the macrophages for the phagocytosis of the virally infected cells and they are produced by nk cells and th1

Question 12

What is the role of the gamma interferon

Answer 12

The role of it is to recruit the macrophages for the phagocytosis of the virally infected cells and they are produced by nk cells and th1
