tissue immunology

Tissue immunology studies how the body's immune system protects tissues from infections, injuries, and harmful substances. It involves immune cells, such as T cells and macrophages, which reside in or travel to tissues to identify and eliminate threats. These cells recognize abnormal or infected cells and coordinate responses to prevent damage. Proper tissue immunology is vital for healing and maintaining health, while also avoiding overreactions that can cause autoimmune diseases. Essentially, it explains how our immune defenses operate within specific parts of our body to keep tissues safe and functional.
