become plasma cells |
|
|
plasma cells |
secrete antibodies |

cytotoxic t cells |
search and destroy by a cell to cell interaction -directly responsible for cell mediated immunity -endogenous antigens |

|
helper t cells |
help other immune system cells do their jobs -secrete chemicals called cytokines to help regulate immune responses -needed for normal b cell and cytotoxic t cell formation |
