What is the Role of Chemotactic Factors in Immune Response?

In the immune response, chemotactic factors are essential for recruiting immune cells to sites where they are needed most. For instance, during an infection, injured tissues release chemotactic factors to attract neutrophils and macrophages. These cells then perform their functions, such as phagocytosis and the release of additional signaling molecules to amplify the immune response. This orchestrated movement and activity help in the effective clearance of pathogens and the initiation of tissue repair processes.
