Human C-Reactive Protein (CRP) is an acute phase protein belonging to the highly conserved pentraxin protein family, like as its homologue, the Serum Amyloid P component (SAP) <ref name="Thompson">PMID: 10368284</ref>.  CRP was named this way because it was found that the protein could precipitate the "C" polysaccharide derived from ''Streptococcus pneumoniae'' cell wall <ref>PMID: 15337754</ref><ref name="kumar">PMID: 21541851</ref>.

Although it is a normal serum protein (healthy humans have a CRP rate which is generally about 1 μg/mL<ref name="kumar"/>), its circulating concentration rises rapidly and extensively (as much as 1000-fold or more <ref name="Black"/>) in a cytokine-mediated in response to an infection, an inflammation or a tissue injury. In this way, serum CRP rate is empirically dose to detect many human disease <ref name="Thompson"/>.  CRP can be defined as a target for the development of cardioprotection and neuroprotection<ref name="kumar"/>. CRP is secreted by the liver into the blood circulation<ref name = "Alex"/> during inflammatory states: the acute phase response, in which the synthesis of a lot of plasma proteins increased <ref name="Black"/>.
