The membrane attack complex (MAC) or terminal complement complex (TCC) is a complex of proteins typically formed on the surface of pathogen cell membranes as a result of the activation of the host’s complement system, and as such is an effector of the immune system
From Wikipedia, the free encyclopedia See also: MACPF The membrane attack complex (MAC) or terminal complement complex (TCC) is a complex of proteins typically formed on t
Complement control protein are proteins that interact with components of the complement system
The complement system is tightly regulated by a network of proteins known as “regulators of complement activation (RCA)” that help distinguish target cells as “
