Immune Response Flashcards
(31 cards)
Reaction of the immune system, specifically the immune cells, when the body is exposed to foreign agent
immune response
What are the factors that affect immune response?
Overall health status, Age, Dose/ Route of antigen administration, Genetic control of the immune response
True or False. Newborns’ immune system have already fully developed thus, they have strong immune response upon espodure to certain antigens.
False, Newborns’ immune system have not yet fully developed and is still in the process of development, thus having a weaker immune response.
Do geriatrics have strong or weak immune response?
Weak
The higher the dose of the antigen/the greater the antigen exposed to the immune system, the __________ (stronger or weaker) the immune response
stronger
True or False. When a person is vaccinated with a particular antigen, the dose of antigen is not considered to ensure the elicitation of immune response.
False. When a person is vaccinated with a particular antigen, the dose of antigen is considered to ensure the elicitation of immune response.
Common way of administering a vaccine is __________
Intramuscular/Subcutaneous
Best route but uncommon way of administering antigen is _________
Intravenous (IV)
It is defined as genetically controlled manner of activating and eliciting immune response
Major Histocompatibility Complex (MHC)
How many phases does primary immune response have?
4 (Lag, Log, Plateau, Decline)
The phase in the primary response wherein the antibody is not yet detectable
Lag Phase
The phase in the primary response wherein the antigen is being processed by the immune cells.
Lag Phase
The phase in the primary response wherein peak titer of the antibody is seen
Log Phase
The phase in the primary response wherein antibody titer increases logarithmically
Log Phase
The phase in the primary response wherein antibody titer stabilizes
Plateau/ Stationary
The phase in the primary response wherein there is an equilibrium/balance between antibody synthesis or production versus the antibody catabolism
Plateau/ Stationary
Other name of Log Phase
Exponential phase
Other name of plateau phase
Stationary phase
The phase in the primary response wherein antibody catabolism is increasing
Decline
The phase in the primary response wherein catabolism of antibody exceeds the production of antibody
Decline
The phase in the primary response wherein antibody titer is decreasing
Decline
Why does the antibody titer decreases during phase of decline?
Because the catabolism of antibody is greater than the production of antibody
If the antigen is already exposed the second time, the antigenic process in the LAG phase is ________ (Longer/ Shorter) because of recognition by the memory cells.
Shorter
What type of cell recognizes the reexposure of the same antigen to the body?
Memory cells
