| Question | Answer |
|---|---|
| categories of biotherapy | cytokines and monoclonal antibodies |

| definition of biotherapy | the use of agents derived from biologic sources or agents that affect biologic responses |
| innate or nonspecific immune response: mechanism of action | primary line of defense, nonspecific, no memory |
| innate or nonspecific immune response: cells involved | neutrophils, monocytes, macrophages, lymphocytes |
| adaptive immune response: mechanism of action | secondary line of defense, specific memory |

| humoral immunity | B lymphocytes, memory B cells, and plasma cells - result is production of immunoglobulins |

| action of interferon | inhibits viral replication, direct antiproliferation of tumor cells, modulates host immune response |
| action of interleukin 2 | promotes proliferation, differentiation, and recruitment of T & B cells and tumor-inflitrating lymphocytes to enhance fighting capabilites |
| action of interleukin 11 | stimulates megakaryocytopoiesis and thrombopoiesis |
| action of biologic response modifiers | may relate to antiangiogenic or anti-inflammatory properties |
