B-Cell vs. T-Cell
- T-Cells
- Migrate and mature in the thymus
- Have Vertical Antigen Receptors
- Bind to Antigen Fragments displayed
by the MHC on the cell surface
- Helper T- Cells
- Cytotoxic T-Cells
- Memory T-Cells
- B-Cells
- Lymphocytes that are part of Adaptive Immunity
- Attack the same specific antigens, function
differently
- Each B- and T- Cell creates ~100,000 of
antigen receptors of ONE TYPE
- B- and T- Cells carrying the same specific antigen
receptor proliferate in the presence of an infection
- Antigen
- Cell product
(toxin-released into
extracellular fluid)
- Pathogenic cell
itself - Proteins or
polysaccharides
- Epitope - accessible
part
- When binded to same antigen, proliferates and
differentiates to:
- Effector Cells (PRIMARY RESPONSE)
- Memory Cells (SECONDARY RESPONSE)
- Remain and mature in the bone-marrow
- Have Y-Shaped Antigen Receptors
- Share Constant Regions - anchors to cell surface
- Bind to the epitope of the
antigen - OUTSIDE cells
- Plasma Cells
- Secretes Antibodies
- Memory B-Cells
