Abstract

Neutrophils are the most abundant polymorphonuclear leukocytes, presenting the first line of defence against infection or tissue damage. To characterize the molecular changes on the protein level in neutrophils during sterile inflammation we established the chemically-induced inflammation (ChIn) assay inadult zebrafish and investigated the proteome dynamics within neutrophils of adult zebrafish upon inflammation. Through label-free proteomics we identified 48 proteins that were differentially regulated during inflammation. Gene ontology analysis revealed that these proteins were associated with cell cycle, nitric oxide signalling, regulation of cytoskeleton rearrangement and intermediate filaments as well as immune-related processes such as antigen presentation, leucocyte chemotaxis and IL-6 signalling. Comparison of protein expression dynamics with transcript expression dynamics suggests the existence of regulatory mechanisms confined to the protein level for some genes. This is the first proteome analysis of adult zebrafish neutrophils upon chemically-induced inflammation providing a valuable reference for future studies using zebrafish inflammation models.
