Final answer:
Macrophages produce various cytokines and chemokines to recruit and communicate with other immune cells.
Step-by-step explanation:
Macrophages are a type of white blood cell that plays a crucial role in the immune response by engulfing and destroying pathogens. When macrophages are activated, they release various cytokines and chemokines to recruit and communicate with other immune cells. Some of the different cytokines/chemokines produced by macrophages include:Interleukin-1 (IL-1): Induces fever, activates endothelial cells, and promotes inflammation. Tumor Necrosis Factor-alpha (TNF-alpha): Promotes inflammation and apoptosis (cell death).Interleukin-6 (IL-6): Stimulates the acute phase response and activates T cells. Chemokine (C-C motif) ligand 2 (CCL2): Attracts monocytes to the site of inflammation. These are just a few examples of the cytokines and chemokines produced by macrophages, and there are many more that play critical roles in immune responses.
