Study Notes
Chapter 07: Immunity
- Neutrophils are phagocytic cells.
- Macrophages process and present antigens during the initial immune response.
- B lymphocytes (B cells) mediate humoral immunity.
- Secondary immune responses are faster and produce higher antibody levels than primary responses.
- Active artificial immunity is acquired through vaccination.
- Type I hypersensitivity occurs when an allergen binds to IgE antibodies on mast cells, releasing chemical mediators.
- Systemic lupus erythematosus (SLE) is characterized by immune complex deposits of antinuclear antibodies.
- HIV targets helper T lymphocytes (CD4 lymphocytes).
- HIV infection impairs both humoral and cell-mediated immunity.
- Opportunistic infections are common in AIDS patients.
- Seroconversion is when antibodies for HIV are detected in the blood.
- Cytokines activate and stimulate B and T lymphocytes.
- Tolerance is the immune system's ability to ignore "self" cells.
- Immunoglobulins (antibodies) have a unique amino acid sequence.
- IgA is found in mucous membranes.
- IgG is transferred from mother to the fetus across the placenta.
- B lymphocytes mature in bone marrow.
