Study Notes
Adaptive Immune System: Lymphocyte Classes and Functions
- Memory and specificity in immune response demonstrated through animal experiments with antigens X and Y
- Antigens X and Y induce production of different antibodies, reflecting specificity
- Secondary response to antigen X is faster and larger than the primary response, illustrating memory
- Antibody levels decline over time after each immunization, varying with type of antigen exposure
- B cells and T cells exhibit similar properties in response to antigens
- Classes of lymphocytes in the adaptive immune system: B lymphocytes, helper T cells, cytotoxic T lymphocytes, and regulatory T cells
- Functions and antigen recognition mechanisms for each class of lymphocytes
- Detailed summary of alpha beta T lymphocytes and B lymphocytes
- Percentage of total lymphocytes for different types of lymphocytes in blood, lymph nodes, and spleen
- B lymphocytes are capable of producing antibodies and mediating humoral immunity
- B cells express membrane-bound antibodies that recognize antigens and initiate cell activation
- Soluble antigens and antigens on the surface of microbes and other cells can bind to B lymphocyte antigen receptors, leading to proliferation and differentiation of antigen-specific B cells
