Study Notes
Antibody Response
- Memory B cells are attributed to the rapid antibody response and higher levels than primary response.
Secondary Response
- IgG antibody is in higher concentration during the secondary response.
Lag Period
- The lag period in the primary response before antibodies are detected is around 7-10 days.
- The lag period in the secondary response before antibodies are detected is minimal or absent.
Primary Response
- IgM antibody is produced in the primary response.
- The amount of antibody produced in the primary response is limited.
- The duration of the antibody response in the secondary response is longer than in the primary response.
Antibody Function
- Opsonization is the process by which antibodies mark pathogens for destruction by phagocytic cells.
- The primary function of antibodies is to bind to specific pathogens and mark them for destruction.
Humoral Immunity
- Humoral immunity is a type of immunity that involves the production of antibodies to protect against pathogens.
- Humoral immunity primarily protects against extracellular pathogens.
- Humoral immunity provides protection against specific exotoxins.
- Humoral immunity directly targets toxin-mediated virulence.
Evaluation of Humoral Immunity
- The processes done for the evaluation of humoral immunity include antibody detection and measurement.
Fetal Immunity
- The fetus can produce IgM antibodies if an infection occurs.
Primary and Secondary Response
- The primary immune response is the initial response to an infection, which is slower and less intense.
- The secondary response is the rapid and more intense response to a subsequent infection.
- The antibody response in the secondary immune response is characterized by a faster and more intense response compared to the primary response.
- IgM is the first antibody to be produced when exposed to infection for the first time, followed by IgG.
- IgM declines earlier than IgG in the immune response.
- After rising for several weeks, the serum antibody concentration eventually declines to a steady-state level.
