<unk> s are a class of proteins whose plasma concentrations increase (positive<unk> s) or decrease (negative<unk> s) in response to inflammation. This response is called the<unk><unk>  reaction (also called<unk><unk>  response).
In response to injury, local inflammatory cells (neutrophil granulocytes and macrophages) secrete a number of cytokines into the bloodstream, most notable of which are the interleukins IL-1, IL-6 and IL-8, and TNF-α.
The liver responds by producing a large number of<unk><unk>  reactants.
