Biochem/physiol Actions

C Reactive Protein (CRP) Fragment 174-185, CRP174-185, is a synthetic peptide fragment of CRP that induces the circulation of soluble IL-6 receptor (sIL-6R) and modulates chemotaxis. CRP174-185 and other CRP peptides such as 77-82 and 201-206 are use to resolve the function of amino acid sequences and domains withing CRP.

We have previously shown that native human C-reactive protein (CRP) produces antitumor effects in experimental animals, and that these effects are mediated primarily through macrophages. More recently, we have observed that RS-83277, a synthetic peptide derived from CRP, appears to

The soluble interleukin 6 receptor (sIL-6R) circulates at elevated levels in various diseases. This suggests that inflammatory mediators control sIL-6R release. Through examination of human neutrophils, it was found that the acute phase reactant C-reactive protein (CRP) activates a threefold

IL-6 plays a pivotal role in immune responses and certain oncologic conditions. The intense investigation of its biological activity and function led to the discovery of two different IL-6-driven signalling pathways. Binding to the membrane-bound IL-6 receptor (mIL-6R, CD126) causes

Human neutrophil granulocytes die rapidly, and their survival is contingent upon rescue from programmed cell death by signals from the environment. Here we report that a novel signal for delaying neutrophil apoptosis is the classic acute phase reactant, C-reactive protein
