Abstract
The peptidyl arginine deiminase (PADI) family is a calcium ion-dependent group of isozymes with sequence similarity that catalyze the citrullination of proteins. Histones can serve as the target substrate of PADI family isozymes, and therefore, the PADI family is involved in NETosis and the secretion of inflammatory cytokines. Thus, the PADI family is associated with the development of inflammatory autoimmune diseases and cancer, reproductive development, and other related diseases. In this review, we systematically discuss the role of the PADI family in the pathogenesis of various diseases based on studies from the past decade to provide a reference for future research.

Abstract
BACKGROUND The miRNA profile is changed after burn or sepsis and is involved in regulating inflammatory reactions. However, the function and molecular mechanism of miRNAs in regulating burn sepsis-induced acute kidney injury (AKI) are still unclear. METHODS In this study, animal and cell sepsis models were established after burned rats were injected with lipopolysaccharide (LPS) or NRK-52E cells treated with LPS, respectively. Cytokine expression, inflammatory cell infiltration, serum creatinine (Scr) and kidney injury molecule-1 (KIM-1) levels were analysed after the indicated treatments. RESULTS Burn sepsis increased the expression of inflammatory factors (TNF-α and IL-1β) and chemokines (MIP-1α, MIP-2 and MCP-1). Moreover, burn sepsis promoted macrophage and neutrophil infiltration into the kidney and upregulated the levels of Scr and KIM-1 in the kidney and urine. Ectopic expression of miR-181c significantly reduced LPS-induced TLR4 protein expression, suppressed KIM-1 mRNA levels and subsequently inhibited the activation of inflammatory genes (TNF-α and IL-1β) and chemokine genes (MIP-1α, MIP-2 and MCP-1). CONCLUSIONS Our results demonstrated that miR-181c could suppress TLR4 expression, reduce inflammatory factor and chemokine secretion, mitigate inflammatory cell infiltration into the kidney and downregulate KIM-1 expression, which might ultimately attenuate burn sepsis-induced AKI.

Abstract
Preeclampsia (PE), presenting with onset hypertension and proteinuria, is a pregnancy-specific disorder that can result in maternal and fetal morbidity and mortality. Insufficient trophoblast invasion and migration has been considered to be an important cause of this disease. The present study aimed to investigate the role of peptidyl arginine deiminase 4 (PAD4), whose knockdown has been previously indicated to reduce inflammation and susceptibility to pregnancy loss in mice, in the development of PE in vitro. Lipopolysaccharide (LPS) was used to treat a human trophoblast cell line (HTR8/SVneo). After PAD4 silencing via transfection with short hairpin RNA against PAD4, the concentrations of inflammatory factors IL-6, IL-12 and monocyte chemoattractant protein (MCP)-1 were measured using ELISA. Cell viability was also measured using Cell Counting Kit-8 assay. HTR8/SVneo cell invasion and migration were detected using Transwell and wound healing assays, respectively. Western blotting was used to measure the expression of citrullinated NF-κB essential modulator (NEMO) and nuclear NF-κB p65 protein levels. TNF-α was applied for evaluating the potential regulatory effects of PAD4 on NF-κB in LPS-stimulated HTR8/SVneo cells. LPS increased the levels of IL-6, IL-12 and MCP-1 and reduced the migration and invasion of HTR8/SVneo cells. PAD4-knockdown was found to markedly reduce the levels of IL-6, IL-12 and MCP-1 secretion. HTR8/SVneo cell invasion and migration was also significantly elevated after PAD4 silencing following LPS exposure. In addition, LPS stimulation notably upregulated the protein levels of citrullinated NEMO and nuclear NF-κB p65, which was restored by PAD4 knockdown. Furthermore, TNF-α treatment partially counteracted the effects of PAD4 knockdown on the secretion of IL-6, MCP-1 and IL-12, which are markers of inflammation, and invasion and migration in LPS-induced HTR8/SVneo cells. To conclude, these results suggest that PAD4 silencing can suppress inflammation whilst promoting invasion and migration by trophoblast cells through inhibiting the NEMO/NF-κB pathway. These findings furthered the understanding in the complex molecular mechanism that can trigger PE and provide a promising target for the treatment of this disease.

Abstract
A growing number of studies have confirmed that immune cells play various key roles in the pathophysiology of acute kidney injury (AKI) development. After the resident immune cells and intrinsic renal cells are damaged by ischemia and hypoxia, drugs and toxins, more immune cells will be recruited to infiltrate through the release of chemokines, while the intrinsic cells promote macrophage polarity conversion, and the immune cells will promote various programmed deaths, phenotypic conversion and cycle arrest of the intrinsic cells, ultimately leading to renal impairment and fibrosis. In the complex and dynamic immune microenvironment of AKI, the bidirectional interaction between immune cells and intrinsic renal cells affects the prognosis of the kidney and the progression of fibrosis, and determines the ultimate fate of the kidney.

Abstract
Citrullination of proteins is crucial for the formation of neutrophil extracellular traps (NETs) − strands of nuclear DNA expulsed in the extracellular environment along with antimicrobial proteins in order to halt the spread of pathogens. Paradoxically, NETs may be immunogenic and contribute to inflammation. It is known that for the externalization of DNA, a group of enzymes called peptidyl arginine deiminases (PADs) is required. Current research often looks at citrullination, NET formation, PAD overexpression, and extracellular DNA (ecDNA) accumulation in chronic diseases as separate events. In contrast, we propose that citrullination can be viewed as the primary mechanism of autoimmunity, for instance by the formation of anti-citrullinated protein antibodies (ACPAs) but also as a process contributing to chronic inflammation. Therefore, citrullination could be at the center, connecting and impacting multiple inflammatory diseases in which ACPAs, NETs, or ecDNA have already been documented. In this review, we aimed to highlight the importance of citrullination in the etiopathogenesis of a number of chronic diseases and to explore the diagnostic, prognostic, and therapeutic potential of the citrullination-NET axis.

Abstract
Aims: Vascular inflammation is critical for the development and progression of atherosclerosis. Previously, we reported that neutrophils adhere to the vascular endothelium in low-density lipoprotein receptor null mice fed a high-fat diet through hypercitrullination of histone H3 by peptidylarginine deiminase 4 (PAD4) in neutrophils. However, the involvement of PAD4 and citrullination of proteins other than histone H3 in neutrophil adhesion is not well known. In this study, we investigated the function of PAD4 and identified citrullinated proteins during vascular inflammation.
Methods: We pefformed flow assay under physiological flow conditions using differentiated HL-60 (dHL-60) cells stimulated with CXCL1 and human umbilical vein endothelial cells (HUVECs). Furthermore, phalloidin stain for dHL-60 stimulated with CXCL1 to observe F-actin polymerization and immunohistochemistry for the activated β2-integrin was conducted. To identify a target of citrullination in the cytoplasm of dHL-60 cells, liquid chromatography-mass spectrometry (LC-MS/MS) for dHL-60 stimulated with CXCL1 was performed.
Results: Inhibition or knockdown of PAD4 significantly decreased adhesion of under physiological flow conditions. Thr-Asp-F-amidine trifluoroacetate salt (TDFA), a PAD4 inhibitor, inhibited cytoplasmic translocation of PAD4 by CXCL1. TDFA or knockdown of PAD4 significantly decreased expression of β2-integrin and F-actin polymerization activated by CXCL1. Moreover, LC-MS/MS identified protein disulfide isomerase A1 (PDIA1) as a target of citrullination in the cytoplasm of dHL-60 cells. Knockdown of PDIA1 significantly decreased adhesion of dHL-60 cells to HUVECs, expression of β2-integrin, and F-actin polymerization.
Conclusions: Cytoplasmic translocation of PAD4 by CXCL1 induces neutrophil adhesion to vascular endothelial cells and citrullination of PDIA1.

Abstract
Ischemia reperfusion injury (IRI) is the most common cause of in-hospital AKI and is associated with increased morbidity and mortality. IRI is associated with an early phase of inflammation primarily regulated by the canonical NFκB signaling pathway. Despite recent advances in our understanding of the pathogenesis of IRI, few therapeutic strategies have emerged. The purpose of this manuscript is to review interventions targeting NFκB after IRI.

Abstract
Purpose A targeted drug delivery system that combines protein-arginine deiminase type-4 (PAD4) inhibitors YW3-56 (356) with PTT of NPs is constructed to both decrease the accumulation of gold in metabolic organs and reduce the dose of chemotherapeutic agents. Patients and Methods In vitro cytotoxicity test and in vivo S180 tumor-bearing mice model were used to compare antitumor activity of 356-modified gold nanospheres and nanorods. The A549 tumor-bearing mice model was also exploited in antitumor assessment. In addition, ICP-MS, blood cell analyzer and blood biochemistry analyzer are applied for assessing the biosafety of NPs. Results Both 356-modified gold nanospheres and nanorods showed antitumor activity. However, 356-loaded gold nanorods are found to have better tumor inhibitory activity than 356-loaded gold nanospheres in the presence of laser and without laser irradiation. Thus, 356-loaded gold nanorods are selected to be applied for chemo-photothermal combined therapy on in vivo. We find that combination therapy could inhibit tumor growth and reduce lung tumor metastasis and inflammatory infiltration compared with individual therapy. It triggers apoptosis in tumor tissue observed by TUNEL assay and TEM pictures. Conclusion Thus, an RGD targeting and PAD4 inhibitor-loaded system are established based on chemo-photothermal combined therapy. It could inhibit tumor growth, prevent lung metastasis and improve biosafety.

Inhibition of Peptidyl Arginine Deiminase-4 Prevents Renal Ischemia-Reperfusion-Induced Remote Lung Injury. Mediators Inflamm 2020; 2020:1724206.

Abstract
Ischemia reperfusion (IR) can lead to acute kidney injury and can be complicated by acute lung injury, which is one of the leading causes of acute kidney injury-related death. Peptidyl arginine deiminase-4 (PAD4) is a member of the PAD enzyme family and plays a critical role in inflammatory reactions and neutrophil extracellular trap formation in a variety of pathological conditions. It has been reported that PAD4 inhibition can protect certain organs from ischemic injury. In this study, we aimed to understand the mode of action of PAD4 in renal ischemia-reperfusion-mediated acute lung injury. Bilateral renal pedicle occlusion was induced for 30 min followed by reperfusion for 24 h. A specific inhibitor of PAD4, GSK484, was delivered via intraperitoneal injection to alter the PAD4 activity. The pulmonary PAD4 expression, pulmonary impairment, neutrophil infiltration, Cit-H3 expression, neutrophil extracellular trap formation, inflammatory cytokine secretion, and pulmonary apoptosis were analyzed. We found that renal ischemia reperfusion was associated with pulmonary pathological changes and increases in neutrophil infiltration, neutrophil extracellular trap formation, and inflammatory cytokine secretion in the lungs of the recipient animals. Suppression of PAD4 by GSK484 reduced remote lung injury by mitigating neutrophil infiltration, neutrophil extracellular trap formation, apoptosis, and inflammatory factor secretion. Our findings demonstrate that specific PAD4 inhibition by GSK484 may be an effective strategy to attenuate distant lung injury complicating renal ischemia-reperfusion injury.

Abstract
We determined that renal proximal tubular (PT) NF-κB essential modulator (NEMO) plays a direct and critical role in ischemic acute kidney injury (AKI) using mice lacking renal PT NEMO and by targeted renal PT NEMO inhibition with mesoscale nanoparticle-encapsulated NEMO binding peptide (NBP MNP). We subjected renal PT NEMO-deficient mice, WT mice, and C57BL/6 mice to sham surgery or 30 minutes of renal ischemia and reperfusion (IR). C57BL/6 mice received NBP MNP or empty MNP before renal IR injury. Mice treated with NBP MNP and mice deficient in renal PT NEMO were protected against ischemic AKI, having decreased renal tubular necrosis, inflammation, and apoptosis compared with control MNP-treated or WT mice, respectively. Recombinant peptidylarginine deiminase type 4 (rPAD4) targeted kidney PT NEMO to exacerbate ischemic AKI in that exogenous rPAD4 exacerbated renal IR injury in WT mice but not in renal PT NEMO-deficient mice. Furthermore, rPAD4 upregulated proinflammatory cytokine mRNA and NF-κB activation in freshly isolated renal proximal tubules from WT mice but not from PT NEMO-deficient mice. Taken together, our studies suggest that renal PT NEMO plays a critical role in ischemic AKI by promoting renal tubular inflammation, apoptosis, and necrosis.

Abstract
Peptidylarginine deiminases (PADs) are a family of calcium-regulated enzymes that are phylogenetically conserved and cause post-translational deimination/citrullination, contributing to protein moonlighting in health and disease. PADs are implicated in a range of inflammatory and autoimmune conditions, in the regulation of extracellular vesicle (EV) release, and their roles in infection and immunomodulation are known to some extent, including in viral infections. In the current study we describe putative roles for PADs in COVID-19, based on in silico analysis of BioProject transcriptome data (PRJNA615032 BioProject), including lung biopsies from healthy volunteers and SARS-CoV-2-infected patients, as well as SARS-CoV-2-infected, and mock human bronchial epithelial NHBE and adenocarcinoma alveolar basal epithelial A549 cell lines. In addition, BioProject Data PRJNA631753, analysing patients tissue biopsy data (n = 5), was utilised. We report a high individual variation observed for all PADI isozymes in the patients' tissue biopsies, including lung, in response to SARS-CoV-2 infection, while PADI2 and PADI4 mRNA showed most variability in lung tissue specifically. The other tissues assessed were heart, kidney, marrow, bowel, jejunum, skin and fat, which all varied with respect to mRNA levels for the different PADI isozymes. In vitro lung epithelial and adenocarcinoma alveolar cell models revealed that PADI1, PADI2 and PADI4 mRNA levels were elevated, but PADI3 and PADI6 mRNA levels were reduced in SARS-CoV-2-infected NHBE cells. In A549 cells, PADI2 mRNA was elevated, PADI3 and PADI6 mRNA was downregulated, and no effect was observed on the PADI4 or PADI6 mRNA levels in infected cells, compared with control mock cells. Our findings indicate a link between PADI expression changes, including modulation of PADI2 and PADI4, particularly in lung tissue, in response to SARS-CoV-2 infection. PADI isozyme 1-6 expression in other organ biopsies also reveals putative links to COVID-19 symptoms, including vascular, cardiac and cutaneous responses, kidney injury and stroke. KEGG and GO pathway analysis furthermore identified links between PADs and inflammatory pathways, in particular between PAD4 and viral infections, as well as identifying links for PADs with a range of comorbidities. The analysis presented here highlights roles for PADs in-host responses to SARS-CoV-2, and their potential as therapeutic targets in COVID-19.

Targeting NF-κB by the Cell-Permeable NEMO-Binding Domain Peptide Improves Albuminuria and Renal Lesions in an Experimental Model of Type 2 Diabetic Nephropathy. Int J Mol Sci 2020; 21:ijms21124225.

Abstract
Diabetic nephropathy (DN) is a multifactorial disease characterized by hyperglycemia and close interaction of hemodynamic, metabolic and inflammatory factors. Nuclear factor-κB (NF-κB) is a principal matchmaker linking hyperglycemia and inflammation. The present work investigates the cell-permeable peptide containing the inhibitor of kappa B kinase γ (IKKγ)/NF-κB essential modulator (NEMO)-binding domain (NBD) as therapeutic option to modulate inflammation in a preclinical model of type 2 diabetes (T2D) with DN. Black and tan, brachyuric obese/obese mice were randomized into 4 interventions groups: Active NBD peptide (10 and 6 µg/g body weight); Inactive mutant peptide (10 µg/g); and vehicle control. In vivo/ex vivo fluorescence imaging revealed efficient delivery of NBD peptide, systemic biodistribution and selective renal metabolization. In vivo administration of active NBD peptide improved albuminuria (>40% reduction on average) and kidney damage, decreased podocyte loss and basement membrane thickness, and modulated the expression of proinflammatory and oxidative stress markers. In vitro, NBD blocked IKK-mediated NF-κB induction and target gene expression in mesangial cells exposed to diabetic-like milieu. These results constitute the first nephroprotective effect of NBD peptide in a T2D mouse model that recapitulates the kidney lesions observed in DN patients. Targeting IKK-dependent NF-κB activation could be a therapeutic strategy to combat kidney inflammation in DN.

Abstract
Acute kidney injury (AKI) due to renal ischemia reperfusion (IR) is a major clinical problem without effective therapy and is a significant and frequent cause of morbidity and mortality during the perioperative period. Although the pathophysiology of ischemic AKI is not completely understood, several important mechanisms of renal IR-induced AKI have been studied. Renal ischemia and subsequent reperfusion injury initiates signaling cascades mediating renal cell necrosis, apoptosis, and inflammation, leading to AKI. Better understanding of the molecular and cellular pathophysiological mechanisms underlying ischemic AKI will provide more targeted approach to prevent and treat renal IR injury. In this review, we summarize important mechanisms of ischemic AKI, including renal cell death pathways and the contribution of endothelial cells, epithelial cells, and leukocytes to the inflammatory response during ischemic AKI. Additionally, we provide some updated potential therapeutic targets for the prevention or treatment of ischemic AKI, including Toll-like receptors, adenosine receptors, and peptidylarginine deiminase 4. Finally, we propose mechanisms of ischemic AKI-induced liver, intestine, and kidney dysfunction and systemic inflammation mainly mediated by Paneth cell degranulation as a potential explanation for the high mortality observed with AKI.
