H3K4me3-marked histone orchestrates neutrophil plasticity from immunity to tissue regeneration. H3K4me3-marked histone orchestrates neutrophil plasticity from immunity to tissue regeneration

In this study, we used chromatin immunoprecipitation sequencing (ChIP-Seq) analysis of histone H3K4me3-marked, to identify various TSSs associated with LPS-, TNF-alfa- and IL-10-stimulated neutrophils from healthy individuals, as well as neutrophils derived from the patients with sepsis (systemic septic inflammation with LPS-stimulated neutrophils), NMOSD (aseptic inflammation with neutrophils pre-activated by TNF-alfa and periodontitis (localized self-limiting septic inflammation with IL-10-positive neutrophils). We provided comprehensive epigenomic analysis within H3K4me3- marked histone that allowed us to identify human neutrophil regulators affecting their plasticity during inflammation as well as suppression. Overall design: Chromatin immunoprecipitation sequencing (ChIPseq) H3K4me3 histone analysis in circulating neutrophils isolated from helathy voluntires stimulted in vitro by IL-10, TNF-alfa or LPS, as well as neutrophils derived from the patients with sepsis (systemic septic inflammation with LPS-stimulated neutrophils), NMOSD (aseptic inflammation with neutrophils pre-activated by TNF-alfa and periodontitis (localized self-limiting septic inflammation with IL-10-positive neutrophils).
