SUMMARY OF B CELLS
- Antibody-mediated/humoral immunity
- B cells are lymphocytes
- Triggered by T helper cells
- Every B cell is Specific to an antigen
- Produced and matures in the bone marrow
- Mass amounts of antibodies are produced to kill off antigen
- B cells divide into plasma B cells which have a specific antibody to an antigen
- Antibodies promote clumping of cells, also known as agglutination, where phagocytes engulf all antigens and cells
- Plasma B cells produce antibodies which kills of specific antigens
- Memory cells remember specific antigens so if the body were to come across the antigen again, the B cells will kill off the antigen faster
- There are 5 actions of antibodies; neutralizing antigen, immobilizing bacteria, activating complement, agglutination and precipitation Antigen and enhancing phagocytosis.
- B cells have MHC class 2 antigen on their membrane
