Therefore, CRP could mediate E-LDL participating in the early stage of atherogenesis. CRP is an ancient conserved protein whose initial role as a pattern recognition molecule may have been to defend against bacterial infections, but whose present biological role appears quite complex. CRP is protective against a variety of bacterial infections and inflammatory stimuli as an opsonin. It is likely that the activity of CRP in humans is either pro- or anti-inflammatory is dependent on the context in which it is acting.
