| ___ are small proteins released by activated lymphocytes and macrophages, and by tissue cells infected with viruses. Via second messengers, triggers production of antiviral proteins | interferons |
| interferons are examples of _____, chemical messengers released by tissue cells to coordinate local activities | cytokines |
| ____ interferons are produced by cells infected with viruses. They attract and stimulate NK cells and enhance resistance to viral infection | alpha a |
| ____ interferons are secreted by fibroblasts, slow inflammation in a damaged area | beta b |
| ____ interferons are secreted by T and NK cells, stimulate macrophage activity | gamma y |
| ____ pathway begins when properdin interact in the plasma. The end result is the attachment of an activated complement protein to the bacterial cell wall | alternative |
| ____ pathway begins when a complement protein attaches to antibody molecules. The end result is conversion of an inactive complement protein to an activated form that attaches to the cell wall | classical pathway |
| a coating of complement proteins and antibodies attract phagocytes and makes the target cell easier to engulf. This enhancement of phagocytosis is called ____ | opsonization |
