Neutrophil Extracellular Traps Mediate Acute Liver Failure in Regulation of miR-223/neutrophil Elastase Signaling in Mice

Project description:Marked enhancement of neutrophil infiltration of the liver is a hallmark of acute liver failure (ALF), a severe life-threatening disease with varying etiologies. However, the mechanisms underlying the regulation of neutrophil entry into the liver and their pathophysiological role during ALF development remain poorly characterized.

Peptidylarginine deiminase 4 deficiency improves elastase-induced formation of neutrophil extracellular traps and emphysema in mouse lung

Project description:Neutrophil extracellular traps (NETs) are associated with the extracellular release of nuclear chromatin decorated with cytoplasmic proteins. Excessive release of NETs has been reported in chronic lung diseases, including chronic obstructive pulmonary disease (COPD). However, the role of NETs in the pathogenesis of COPD remains unclear. Peptidylarginine deaminase 4 (PAD4) contributes to NET formation. Therefore, in an elastase (ELS)-induced emphysema mouse model, we examined the role of PAD4 using the Padi4 gene knockout (KO) mice. First, we confirmed that ELS induced NET formation in the lungs. Although PAD4 deficiency did not affect the cellular profile of bronchoalveolar lavage fluid (BALF), PAD4 deficiency suppressed ELS-induced neutrophil migration and NET expression in the parenchyma of the lung. Additionally, PAD4 deficiency ameliorated emphysema and apoptosis in lung cells. Finally, we examined the effects of PAD4 on comprehensive gene expression signatures using RNA sequencing. Enrichment analysis of the transcriptomic data revealed that the expression of several genes associated with COPD pathogenesis was altered in the KO mice. Overall, the results suggest that PAD4 deficiency improves NET formation and emphysema in the lungs; this pathway can be a potential therapeutic target for the treatment of COPD.

Proteomic analysis of neutrophil extracellular traps (healthy control, rheumatoid arthritis, systemic lupus erythematosus)_C4PR_LIV

Project description:Neutrophil Extracellular Traps (NETs) are chromatin-derived extracellular structures that are expelled from neutrophils in response to infectious or inflammatory stimuli. NET DNA structures are decorated with proteins including histones, myeloperoxidase and neutrophil elastase. NETs are implicated in the development of auto-immunity in diseases including rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) through the externalisation of intracellular neoepitopes e.g. dsDNA and nuclear proteins in SLE and citrullinated peptides in RA. The aim of this work was to use quantitative proteomics to identify and measure NET proteins produced by neutrophils from healthy individuals, and from patients with RA and SLE.

The cytosolic DNA sensor cGAS recognizes Neutrophil Extracellular Traps

Project description:Neutrophil Extracellular Traps (NETs) are structures consisting of chromatin and antimicrobial molecules that are released by neutrophils during a form of regulated cell death called NETosis. NETs trap invading pathogens, promote coagulation and activate myeloid cells to produce Type I interferons (type I IFN), proinflammatory cytokines that regulate the immune system. The mechanism of NET recognition by myeloid cells is not yet clearly identified. Here we show that macrophages and other myeloid cells phagocytose NETs. Once in phagosomes, NETs translocate to the cytosol, where they activate the DNA sensor cyclic GMP-AMP synthase (cGAS) and induce type I IFN expression. cGAS recognizes the DNA backbone of NETs. Interestingly, the NET associated serine protease Neutrophil Elastase (NE) mediates the activation of the pathway. We confirmed that NETs activate cGAS in vivo. Thus, our findings identify cGAS as a major sensor of NETs, mediating the immune activation during infection and in auto-immune diseases.
