Study Notes
Humoral Immunity Overview
- Humoral immunity is a component of the adaptive immune system that involves the production of antibodies by B cells.
- It primarily protects against extracellular pathogens, including bacteria and viruses found in body fluids.
Antibody Response
- The first antibody to be produced during a primary infection is Immunoglobulin M (IgM).
- In the primary immune response, there is a lag period of about 4 to 7 days before antibodies become detectable in the serum.
Immune Response Types
- The secondary immune response occurs upon re-exposure to the same pathogen, resulting in a faster and more robust antibody production.
- Immunoglobulin G (IgG) follows IgM in the immune response, providing long-term protection.
Antibody Dynamics
- Immunoglobulin M (IgM) levels typically decline faster than IgG levels after an immune response peaks.
- Serum antibody concentration will begin to decline after reaching its peak, notably over several weeks to months, depending on the immune response.
