Mast cells are the first responders to injury or infection and release histamine, which triggers the dilation and increased permeability of blood vessels. This allows immune cells, such as phagocytes, to move into the wound area and begin the process of removing any pathogens or debris. The complement system and interferons play roles in later stages of the inflammatory response.
