Complement C4a is a protein that is part of the complement system, which is a group of proteins that work together to help the immune system fight off infections. C4a is produced when the complement system is activated, and it plays a role in inflammation and the recruitment of immune cells to the site of infection. It is also involved in the clearance of immune complexes and the regulation of the complement system.
