Immune Response Flashcards
The body’s reaction, specifically the Immune System when a foreign agent enters the body
Immune Response
Factors affecting immune response
- Overall health status
- Age
- Concentration and route of administration of antigen to the host body
- Genetic control of immune response
Four phases of immune response:
▪ Lag
▪ Log
▪ Plateau
▪ Decline
Predominant antibody in Primary Immune Response
IgM
The primary immune response wherein no antibody is detectable – Only the processing phase
Lag Phase
The primary immune response phase wherein the immune cells process the foreign antigens that had entered the body
Lag Phase
The primary immune response phase wherein antigens are yet to be distributed in the tissue
Lag Phase
The primary immune response phase wherein the antibody production is increasing logarithmically
Log/Exponential Phase
The primary immune response phase wherein antibody titer is stable
Plateau/Stationary Phase
The primary immune response phase wherein there is equilibrium between antibody production and antibody catabolism
Plateau/Stationary Phase
The primary immune response phase wherein antibody is catabolized
Decline Phase
The primary immune response phase wherein titer is decreased
Decline Phase
Other term for secondary immune response
Anamnestic / Memory response
Elicited by a second or any subsequent exposure to the
same antigen
Secondary Immune Response
Predominant antibody in Secondary Immune Response
IgG
