Study Notes
- B-lymphocytes synthesize circulating humeral antibodies.
- The immune system recognizes and responds to tissue grafts and newly introduced proteins.
- Antibodies are highly specific reagents for detecting any class of molecules.
- Immunologic approaches are widely used in clinical medicine, research, and vaccine development.
- Tumor cells do not respond to signals to stop growing, so the immune system creates proteins to stop or kill them.
- Deficient immunity results in increased susceptibility to infections, exemplified by AIDS.
- Vaccination boosts immune defenses and protects against infections.
- The innate immune system defends against infection in a non-specific manner.
- The immune system exhibits remarkable diversity, long memory, and specificity.
- The organs and cells in the immune response include the thymus, spleen, lymphatic tissue, and various types of cells such as B-lymphocytes, T-lymphocytes, and macrophages.
