What is the difference between a PMN and a macrophage???
A. Although both are phagocytes, they also have some specialized functions. The PMN is the first phagocyte recruited to sites of inflammation. They are loaded with lytic enzymes, and are very efficient at phagocytic killing. Macrophages are less capable of phagocytic killing unless activated, but they can also serve as antigen-presenting cells, thus they can help in the activation of helper T cells.
