[0131] Chemerin140 exerts anti-inflammatory effect on activated macrophages that are abrogated by protease inhibitors

[0132] Previous studies have shown that serine proteases released by polymorphonuclear cells (PMNs) after degranulation cleave the C-terminus of the precursor chemerin and release its chemotactic potential (Wittamer V et al. J Immunol. 2005 Jul 1;175(1):487-493). However, the anti-inflammatory effect of the peptides produced by further proteolytic processing of chemerin is novel and inventive.

[0133] Murine peritoneal macrophages (PMθ, also referred to herein as PMΦ) were cultured under various conditions: untreated; LPS (100 ng / ml) and IFNγ (20 ng / ml) for 15 hours; chemerin (1 pM) pretreated 1 hour, followed by LPS / IFNγ, 15 hours; leupeptin (protease inhibitor; 15 mg / ml) and chemerin (1 pM), 1 hour, followed by LPS / IFNγ, 15 hours; or dexamethasone (positive control ; 1 μM, pretreatment for 1 hour, followed by LPS / IFNγ for 15 hours.

Abstract

This invention provides the use of one or more peptides derived from the C-terminal end of a Chemerin protein, or analogs or derivatives thereof for treatment of inflammation and / or endotoxic shock and / or treatment of wounds and / or reduction of levels of inflammatory chemokines in a subject, and one or more peptides derived from the C-terminal end of a Chemerin protein, or analogs or derivatives thereof for use in the treatment of inflammation and / or endotoxic shock, and / or wounds, or for the reduction of levels of inflammatory mediators.

Description

[0001] This application is a divisional application with a filing date of March 25, 2008, entitled "Treatment of Inflammation and / or Endotoxic Shock", and the applicant is ISIS Innovations Limited. technical field [0002] The present invention relates to the treatment of inflammation and / or endotoxic shock and / or the reduction of levels of inflammatory chemokines, and to a combination for the treatment of inflammation and / or endotoxic shock, or for the reduction of levels of inflammatory mediators thing. Background technique [0003] Inflammation is an integral part of the pathogenesis of many human and animal diseases and also occurs as a result of physical, chemical or traumatic injury to human or animal body tissues. Typically, the immune response results in the systemic release of endogenous chemical mediators, which results in vasodilation, neutrophil migration, chemotaxis, and increased vascular permeability. Regardless of where and what causes an immune response, th...
