Study Notes
Overview of the Immune System and Immunization
- The immune system has a "memory" that allows it to respond more quickly to later invasions by the same pathogen.
- Antigens are substances that mobilize the immune system and provoke an immune response.
- Major histocompatibility complex (MHC) proteins are unique markers on human cells recognized by the immune system.
- B lymphocytes mature in the bone marrow and produce antibodies for antibody-mediated immunity.
- T lymphocytes mature in the thymus gland and are central to cell-mediated immunity.
- Antibodies inactivate pathogens by causing agglutination or by marking them for destruction.
- Five classes of antibodies (IgG, IgM, IgA, IgD, and IgE) have distinct functions and locations in the body.
- T cells play a role in cell-mediated immunity and are determined by surface proteins CD4 or CD8.
- Active immunization involves administering a vaccine to activate the body's immune system in advance.
- Passive immunization involves giving antibodies prepared in advance to help fight existing or anticipated infections.
- Passive immunization can occur naturally through the placenta and breast-feeding, conferring short-term immunity to the fetus and newborn.
- Passive immunization is somewhat effective against existing infections and provides at least some short-term immunity.
