Study Notes
Adaptive Immunity
- Adaptive Immunity provides a tailored response to pathogens, ensuring long-term defense through memory.
- Humoral Immunity: Involves B cells that produce antibodies targeting specific antigens in body fluids.
- Cell-Mediated Immunity: Relies on T cells to identify and eliminate infected or cancerous cells.
- Lymphocytes are the primary cells of adaptive immunity, distinguishing between foreign antigens.
B Cells and Antibody Production
- B Cells: Identify free-floating antigens and generate corresponding antibodies for neutralization and opsonization.
T Cells and Antigen Recognition
- T Cells: Recognize and respond to processed antigens that are presented by Major Histocompatibility Complex (MHC) molecules on the surface of other cells.
Recognition System
- Highly Specific Receptors enable precise targeting of pathogens.
- B Cell Receptor (BCR): Facilitates binding to specific antigens for B cell activation.
- T Cell Receptor (TCR): Permits T cells to recognize antigens displayed by MHC on infected or damaged cells.
- Specificity: Each lymphocyte possesses unique receptors for individual antigens, ensuring a targeted immune response.
