amplification system


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.

amplification system

Any group of proteins that act in a co-ordinated sequence, forming positive feedback loops for expanding the response to a low intensity signal.

Amplification systems 
Coagulation (e.g., factor Xa)—Activates factor "X" in the presence of factor VIII, Ca2+ and phospholipid. 
Complement—Augments B-cell response. See Alternative and Classic pathways. 
Cytokines—Amplifies T-cell response, interleukinss, kinins, lipid mediators and mast cell products.
