Abstract
Background SARS-CoV-2-induced acute lung injury but its nucleocapsid (N) and/or Spike (S) protein involvements in the disease pathology remain elusive. Methods In vitro, the cultured THP-1 macrophages were stimulated with alive SARS-CoV-2 virus at different loading dose, N protein or S protein with/without TICAM2-siRNA, TIRAP-siRNA or MyD88-siRNA. The TICAM2, TIRAP and MyD88 expression in the THP-1 cells after N protein stimulation were determined. In vivo, naïve mice or mice with depletion macrophages were injected with N protein or dead SARS-CoV-2. The macrophages in the lung were analyzed with flow cytometry, and lung sections were stained with H&E or immunohistochemistry. Culture supernatants and serum were harvested for cytokines measurements with cytometric bead array. Results Alive SARS-CoV-2 virus or N protein but not S protein induced high cytokine releases from macrophages in a time or virus loading dependent manner. MyD88 and TIRAP but not TICAM2 were highly involved in macrophage activation triggered by N protein whilst both inhibited with siRNA decreased inflammatory responses. Moreover, N protein and dead SARS-CoV-2 caused systemic inflammation, macrophage accumulation and acute lung injury in mice. Macrophage depletion in mice decreased cytokines in response to N protein. Conclusion SARS-CoV-2 and its N protein but not S protein induced acute lung injury and systemic inflammation, which was closely related to macrophage activation, infiltration and release cytokines.

Abstract
Survival of transplanted hearts is often limited by cold ischemia time. Here, we assessed the effects of the small molecular compound TJ-M2010-5 on graft preservation. In a cardiac cold ischemia/reperfusion model, TJ-M2010-5 ameliorated myocardial ischemia/reperfusion injury (MIRI) in histidine-tryptophan-ketoglutarate (HTK) organ preservation solution. When applied in HTK solution and on donors/recipients respectively, TJ-M2010-5 exerted optimal effects when applied as an additive in the HTK solution. TJ-M2010-5-administered mice exhibited shorter rebeating time; higher beating score; stronger and more regular sinus heart rate; and amelioration of apoptosis, inflammatory reactions, and myocardial injury. Mechanistically, TJ-M2010-5 inhibited the expression of key molecules in the toll-like receptor (TLR) signaling pathway and affected downstream proteins by inhibiting myeloid differentiation factor 88 homodimerization, thereby decreasing myocardial injury. Thus, TJ-M2010-5 may exert protective effects against MIRI by blocking the TLR signaling pathway. Our findings may lead to novel approaches for organ preservation, thereby reducing organ abandonment and improving recipient prognosis. The role of the TLR signaling pathway in MIRI progress and operation procedure of the MIRI model in vivo are presented in a graphical abstract (Online Abstract Figure).

ROS-activated CXCR2 + neutrophils recruited by CXCL1 delay denervated skeletal muscle atrophy and undergo P53-mediated apoptosis. EXPERIMENTAL & MOLECULAR MEDICINE 2022; 54:1011-1023. [PMID: 35864308 PMCID: PMC9356135 DOI: 10.1038/s12276-022-00805-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 03/15/2022] [Accepted: 04/06/2022] [Indexed: 11/17/2022]
Abstract
Neutrophils are the earliest master inflammatory regulator cells recruited to target tissues after direct infection or injury. Although inflammatory factors are present in muscle that has been indirectly disturbed by peripheral nerve injury, whether neutrophils are present and play a role in the associated inflammatory process remains unclear. Here, intravital imaging analysis using spinning-disk confocal intravital microscopy was employed to dynamically identify neutrophils in denervated muscle. Slice digital scanning and 3D-view reconstruction analyses demonstrated that neutrophils escape from vessels and migrate into denervated muscle tissue. Analyses using reactive oxygen species (ROS) inhibitors and flow cytometry demonstrated that enhanced ROS activate neutrophils after denervation. Transcriptome analysis revealed that the vast majority of neutrophils in denervated muscle were of the CXCR2 subtype and were recruited by CXCL1. Most of these cells gradually disappeared within 1 week via P53-mediated apoptosis. Experiments using specific blockers confirmed that neutrophils slow the process of denervated muscle atrophy. Collectively, these results indicate that activated neutrophils are recruited via chemotaxis to muscle tissue that has been indirectly damaged by denervation, where they function in delaying atrophy. Live animal imaging experiments reveal how rapid recruitment of a subset of immune cells helps prevent muscle wasting after peripheral nerve injury. Such injuries take considerable time to heal, and there are no therapies that reliably prevent wasting of muscle lacking nervous innervation. Researchers led by JunJian Jiang and Jianguang Xu at Fudan University, Shanghai, China, have used intravital microscopy to record the cellular and molecular events that follow nerve damage in live mice. They observed heightened production of chemicals that summon immune cells known as neutrophils to the site of the injury. Even though the surrounding muscle cells were initially undamaged in this animal model, the recruited neutrophils delayed subsequent muscle wasting. This neutrophil recruitment was transient, but therapies that elicit a more sustained response could provide durable protection against muscle wasting.

Abstract
Some microRNAs (miRNAs) play important roles in lung ischemia-reperfusion injury (LIRI) injury. Here, this study aimed to examine whether miR-141 was related to lung ischemia-reperfusion injury (IRI) via regulating autophagy and the epidermal growth factor receptor (EGFR), and to explore the underlying signal transduction pathways. To this end, we constructed the LIRI cell model and mouse models, separately. According to RT-qPCR and Western blotting (WB) analysis results, miR-141 up-regulation together with β-catenin and EGFR down-regulation within mouse pulmonary microvascular endothelial cells (PMVECs) or lung tissues was related to lung IRI. Besides, we conducted dual-luciferase reporter assay, which suggested the binding of EGFR to miR-141. In addition, we carried out TUNEL staining, HE staining, and flow cytometric analysis to assess the apoptosis of PMVECs and the injury to mouse lung tissues. Furthermore, we performed light-chain immunofluorescence assay to examine autophagosomes within PMVECs. According to our results, miR-141 suppressed β-catenin level through reducing EGFR level. Besides, the miR-141/EGFR/β-catenin axis enhanced autophagy to aggravate LIRI. To sum up, miR-141 suppresses EGFR expression to inhibit β-catenin level, which subsequently aggravates autophagy and complicates LIRI. The above results offer the candidate therapeutic target for the treatment of lung IRI.

Necroptosis triggers spatially restricted neutrophil-mediated vascular damage during lung ischemia reperfusion injury. Proc Natl Acad Sci U S A 2022; 119:e2111537119.

Abstract
Intravital imaging, oxidative lipidomics, and a transplant model were used to define mechanisms that regulate neutrophil recruitment into lungs during ischemia reperfusion injury, a clinically relevant form of sterile inflammation. We found that early neutrophil-mediated damage is largely confined to the subpleural vasculature, a process that is orchestrated by a spatially restricted distribution of nonclassical monocytes that produce chemokines following necroptosis of pulmonary cells. Neutrophils disrupt the integrity of subpleural capillaries, which is associated with impaired lung function. Neutrophil-mediated vascular leakage is dependent on TLR4 expression on vascular endothelium, NOX4 signaling, and formation of neutrophil extracellular traps. Our research provides insights into mechanisms that regulate neutrophil recruitment during sterile lung inflammation and lays the foundation for developing new therapies. Ischemia reperfusion injury represents a common pathological condition that is triggered by the release of endogenous ligands. While neutrophils are known to play a critical role in its pathogenesis, the tissue-specific spatiotemporal regulation of ischemia-reperfusion injury is not understood. Here, using oxidative lipidomics and intravital imaging of transplanted mouse lungs that are subjected to severe ischemia reperfusion injury, we discovered that necroptosis, a nonapoptotic form of cell death, triggers the recruitment of neutrophils. During the initial stages of inflammation, neutrophils traffic predominantly to subpleural vessels, where their aggregation is directed by chemoattractants produced by nonclassical monocytes that are spatially restricted in this vascular compartment. Subsequent neutrophilic disruption of capillaries resulting in vascular leakage is associated with impaired graft function. We found that TLR4 signaling in vascular endothelial cells and downstream NADPH oxidase 4 expression mediate the arrest of neutrophils, a step upstream of their extravasation. Neutrophil extracellular traps formed in injured lungs and their disruption with DNase prevented vascular leakage and ameliorated primary graft dysfunction. Thus, we have uncovered mechanisms that regulate the initial recruitment of neutrophils to injured lungs, which result in selective damage to subpleural pulmonary vessels and primary graft dysfunction. Our findings could lead to the development of new therapeutics that protect lungs from ischemia reperfusion injury.

Mol Ther 2021; 29:2873-2885.

Abstract
Dysregulated long non-coding RNAs (lncRNAs) have been shown to contribute to the pathogenesis of ischemic stroke. However, the potential role of lncRNAs in post-stroke microglial activation remains largely unknown. Here, we uncovered that lncRNA-U90926 was significantly increased in microglia exposed to ischemia/reperfusion both in vivo and in vitro. In addition, adenovirus-associated virus (AAV)-mediated microglial U90926 silencing alleviated neurological deficits and reduced infarct volume in experimental stroke mice. Microglial U90926 knockdown could reduce the infiltration of neutrophils into ischemic lesion site, which might be attributed to the downregulation of C-X-C motif ligand 2 (CXCL2). Mechanistically, U90926 directly bound to malate dehydrogenase 2 (MDH2) and competitively inhibited the binding of MDH2 to the CXCL2 3' untranslated region (UTR), thus protecting against MDH2-mediated decay of CXCL2 mRNA. Taken together, our study demonstrated that microglial U90926 aggravated ischemic brain injury via facilitating neutrophil infiltration, suggesting that U90926 might be a potential biomarker and therapeutic target for ischemic stroke.

Abstract
Primary graft dysfunction (PGD) is the predominant cause of early graft loss following lung transplantation. We recently demonstrated that donor pulmonary intravascular nonclassical monocytes (NCM) initiate neutrophil recruitment. Simultaneously, host-origin classical monocytes (CM) permeabilize the vascular endothelium to allow neutrophil extravasation necessary for PGD. Here, we show that a CCL2-CCR2 axis is necessary for CM recruitment. Surprisingly, although intravital imaging and multichannel flow cytometry revealed that depletion of donor NCM abrogated CM recruitment, single cell RNA sequencing identified donor alveolar macrophages (AM) as predominant CCL2 secretors. Unbiased transcriptomic analysis of murine tissues combined with murine KOs and chimeras indicated that IL-1β production by donor NCM was responsible for the early activation of AM and CCL2 release. IL-1β production by NCM was NLRP3 inflammasome dependent and inhibited by treatment with a clinically approved sulphonylurea. Production of CCL2 in the donor AM occurred through IL-1R-dependent activation of the PKC and NF-κB pathway. Accordingly, we show that IL-1β-dependent paracrine interaction between donor NCM and AM leads to recruitment of recipient CM necessary for PGD. Since depletion of donor NCM, IL-1β, or IL-1R antagonism and inflammasome inhibition abrogated recruitment of CM and PGD and are feasible using FDA-approved compounds, our findings may have potential for clinical translation.

Abstract
Current immunosuppressive therapy has led to excellent short-term survival rates in organ transplantation. However, long-term graft survival rates are suboptimal, and a vast number of allografts are gradually lost in the clinic. An increasing number of animal and clinical studies have demonstrated that monocytes and macrophages play a pivotal role in graft rejection, as these mononuclear phagocytic cells recognize alloantigens and trigger an inflammatory cascade that activate the adaptive immune response. Moreover, recent studies suggest that monocytes acquire a feature of memory recall response that is associated with a potent immune response. This form of memory is called “trained immunity,” and it is retained by mechanisms of epigenetic and metabolic changes in innate immune cells after exposure to particular ligands, which have a direct impact in allograft rejection. In this review article, we highlight the role of monocytes and macrophages in organ transplantation and summarize therapeutic approaches to promote tolerance through manipulation of monocytes and macrophages. These strategies may open new therapeutic opportunities to increase long-term transplant survival rates in the clinic.
