What is the function of Interleukin 2? | T-cell & NK-cell GROWTH factor |
What is the function of Interleukin 6? | B-cell GROWTH factor |
What is the function of Chemotaxins? | attracts Macrophages to area of Infection |
What are the function of Helper T-cells? | Support Chemical and Cell-Mediated Immunity |
