Abstract
BACKGROUND Immunoglobulin A nephropathy (IgAN) is the most frequent primary glomerulonephritis and the role of IL-6 in pathogenesis is becoming increasingly important. A recent whole genome DNA methylation screening in IgAN patients identified a hypermethylated region comprising the non-coding RNA Vault RNA 2-1 (VTRNA2-1) that could explain the high IL-6 levels. METHODS The pathway leading to IL-6 secretion controlled by VTRNA2-1, PKR, and CREB was analyzed in peripheral blood mononuclear cells (PBMCs) isolated from healthy subjects (HS), IgAN patients, transplanted patients with or without IgAN. The role of double and single-strand RNA in controlling the pathway was investigated. RESULTS VTRNA2-1 was downregulated in IgAN compared to HS and in transplanted IgAN patients (TP-IgAN) compared to non-IgAN transplanted (TP). The loss of the VTRNA2-1 natural restrain in IgAN patients caused PKR hyperphosphorylation, and consequently the activation of CREB by PKR, which, in turn, led to high IL-6 production, both in IgAN and in TP-IgAN patients. IL-6 levels could be decreased by the PKR inhibitor imoxin. In addition, PKR is normally activated by bacterial and viral RNA, and we found that both the RNA poly(I:C), and the COVID-19 RNA-vaccine stimulation significantly increased the IL-6 levels in PBMCs from HS but had an opposite effect in those from IgAN patients. CONCLUSION The discovery of the upregulated VTRNA2-1/PKR/CREB/IL-6 pathway in IgAN patients may provide a novel approach to treating the disease and may be useful for the development of precision nephrology and personalized therapy by checking the VTRNA2-1 methylation level in IgAN patients.

Abstract
BACKGROUND Sepsis is characterized by a dysregulated immune response and metabolic alterations, including decreased high-density lipoprotein cholesterol (HDL-C) levels. HDL exhibits beneficial properties, such as lipopolysaccharides (LPS) scavenging, exerting anti-inflammatory effects and providing endothelial protection. We investigated the effects of CER-001, an engineered HDL-mimetic, in a swine model of LPS-induced acute kidney injury (AKI) and a Phase 2a clinical trial, aiming to better understand its molecular basis in systemic inflammation and renal function. METHODS We carried out a translational approach to study the effects of HDL administration on sepsis. Sterile systemic inflammation was induced in pigs by LPS infusion. Animals were randomized into LPS (n = 6), CER20 (single dose of CER-001 20 mg/kg; n = 6), and CER20 × 2 (two doses of CER-001 20 mg/kg; n = 6) groups. Survival rate, endothelial dysfunction biomarkers, pro-inflammatory mediators, LPS, and apolipoprotein A-I (ApoA-I) levels were assessed. Renal and liver histology and biochemistry were analyzed. Subsequently, we performed an open-label, randomized, dose-ranging (Phase 2a) study included 20 patients with sepsis due to intra-abdominal infection or urosepsis, randomized into Group A (conventional treatment, n = 5), Group B (CER-001 5 mg/kg BID, n = 5), Group C (CER-001 10 mg/kg BID, n = 5), and Group D (CER-001 20 mg/kg BID, n = 5). Primary outcomes were safety and efficacy in preventing AKI onset and severity; secondary outcomes include changes in inflammatory and endothelial dysfunction markers. RESULTS CER-001 increased median survival, reduced inflammatory mediators, complement activation, and endothelial dysfunction in endotoxemic pigs. It enhanced LPS elimination through the bile and preserved liver and renal parenchyma. In the clinical study, CER-001 was well-tolerated with no serious adverse events related to study treatment. Rapid ApoA-I normalization was associated with enhanced LPS removal and immunomodulation with improvement of clinical outcomes, independently of the type and gravity of the sepsis. CER-001-treated patients had reduced risk for the onset and progression to severe AKI (stage 2 or 3) and, in a subset of critically ill patients, a reduced need for organ support and shorter ICU length of stay. CONCLUSIONS CER-001 shows promise as a therapeutic strategy for sepsis management, improving outcomes and mitigating inflammation and organ damage. TRIAL REGISTRATION The study was approved by the Agenzia Italiana del Farmaco (AIFA) and by the Local Ethic Committee (N° EUDRACT 2020-004202-60, Protocol CER-001- SEP_AKI_01) and was added to the EU Clinical Trials Register on January 13, 2021.

Abstract
Cisplatin is one of the most effective chemotherapeutic agents strongly associated with nephrotoxicity. Tubular adult renal progenitor cells (tARPC) can regenerate functional tubules and participate in the repair processes after cisplatin exposition. This study investigated the molecular mechanisms underlying the protective effect of tARPC on renal epithelium during cisplatin nephrotoxicity. By performing a whole-genome transcriptomic analysis, we found that tARPC, in presence of cisplatin, can strongly influence the gene expression of renal proximal tubular cell [RPTEC] by inducing overexpression of CYP1B1, a member of the cytochrome P450 superfamily capable of metabolizing cisplatin and of hypoxia/cancer-related lncRNAs as MIR210HG and LINC00511. Particularly, tARPC exerted renoprotection and regeneration effects via extracellular vesicles (EV) enriched with CYP1B1 and miR-27b-3p, a well-known CYP1B1 regulatory miRNA. The expression of CYP1B1 by tARPC was confirmed by analyzing biopsies of cisplatin-treated renal carcinoma patients that showed the colocalization of CYP1B1 with the tARPC marker CD133. CYP1B1 was also overexpressed in urinary EV purified from oncologic patients that presented nephrotoxicity episodes after cisplatin treatment. Interestingly CYP1B1 expression significantly correlated with creatinine and eGFR levels. Taken together, our results show that tARPC are able to counteract cisplatin-induced nephrotoxicity via CYP1B1 release through EV. These findings provide a promising therapeutic strategy for nephrotoxicity risk assessment that could be related to abundance of renal progenitors.

Abstract
Despite recent technical advances in dialysis care over the past decades, the mortality rate of critically ill patients with acute kidney injury (AKI) requiring dialysis and of chronic kidney disease (CKD) remains unacceptably high. Several preclinical studies have increased our knowledge of the principal mechanisms involved in the pathophysiology of AKI and CKD. Additionally, the development of efficient and specific compensatory sorbent systems in renal replacement therapy to remove unwanted compounds has created the possibility to treat renal diseases and their underlying pathological triggers. Recently, several biomedical blood purification materials have been developed to improve the removal of waste and inflammatory compounds, improve the quality of treatment, and reduce the duration of treatment. This chapter is focused on the principal mechanisms involved in AKI and CKD and the current state of the art for blood purification strategies to identify the most feasible solution to reduce immunological dysfunction and waste compound clearance. In this regard, the current literature underlines the high efficacy of polymethyl methacrylate membrane hemofilters to overcome the shortcomings in the efficiency of current methodologies in removing the excess of metabolic waste and inflammatory mediators from blood. The purpose of this chapter is therefore to enhance physicians' knowledge about PMMA.

Abstract
Kidney transplantation is the first-choice treatment for end-stage renal disease (ESRD). Kidney transplant recipients (KTRs) are at higher risk of experiencing a life-threatening event requiring intensive care unit (ICU) admission, mainly in the late post-transplant period (more than 6 months after transplantation). Urosepsis and bloodstream infections account for almost half of ICU admissions in this population; in addition, potential side effects related to immunosuppressive treatment should be accounted for cytotoxic and ischemic changes induced by calcineurin inhibitor (CNI), sirolimus/CNI-induced thrombotic microangiopathy and posterior reversible encephalopathy syndrome. Throughout the ICU stay, Acute Kidney Injury (AKI) incidence is common and ranges from 10% to 80%, and up to 40% will require renal replacement therapy. In-hospital mortality can reach 30% and correlates with acute illness severity and admission diagnosis. Graft survival is subordinated to baseline estimated glomerular filtration rate (eGFR), clinical presentation, disease severity and potential drug nephrotoxicity. The present review aims to define the impact of AKI events on short- and long-term outcomes in KTRs, focusing on the epidemiologic data regarding AKI incidence in this subpopulation; the pathophysiological mechanisms underlying AKI development and potential AKI biomarkers in kidney transplantation, graft and patients' outcomes; the current diagnostic work up and management of AKI; and the modulation of immunosuppression in ICU-admitted KTRs.

Abstract
End-stage renal disease (ESRD) is characterized by deep disorders in both innate and adaptive immune systems that imply unbalance deactivation and immunosuppression. The central, widely recognized factors responsible for this immune dysregulation are uremia, uremic toxin retention, hemodialysis membrane biocompatibility, and related cardiovascular complications. Recently, several studies strengthened the concept that dialysis membranes are not considered as a simple diffusive/adsorptive device but as a platform to personalize a dialysis approach to improve the quality of life of ESRD patients. Therefore, understanding of the molecules associated with altered immune response is crucial and could lead to therapeutically intervention or adaptation of the dialysis procedure itself for the management of immunological dysfunction of ESRD patients. The polymethyl methacrylate (PMMA)-based membrane is characterized by a symmetrical structure with large-sized pores, providing a better hydrophobic and cationic adsorption capacity compared to the other synthetic membranes. Together with hydrophobic interactions, the high adsorption rate of cytokines (i.e., IL-6) can also be enhanced by the size of nano-pores placed on the membrane surface. PMMA membranes exhibit adsorptive properties for a large amount of uremic toxins including p-cresol and indoxyl sulfate, as well as β2-microglobulin characterized by higher molecular weight, maintaining the diffusive clearance of small molecules like urea with a great biocompatibility. Besides exerting a strong anti-inflammatory effects in line with the improvement of immune responses in patients undergoing dialysis, PMMA also plays a role in modulating adaptive immune response, i.e., can clear blood from soluble CD40, a natural antagonist of the CD40/CD40L signaling that acts inhibiting immunoglobulin production by B cells. This review provides an overview of the main concepts and current understanding of immune dysfunction in hemodialysis and summarizes the recent findings regarding PMMA-based dialysis as potential strategy to restore immune balance in ESRD patients.

Abstract
In the past years, indoxyl sulfate has been strongly implicated in kidney disease progression and contributed to cardiovascular morbidity. Moreover, as a result of its elevated albumin affinity rate, indoxyl sulfate is not adequately cleared by extracorporeal therapies. Within this scenario, although LC-MS/MS represents the conventional approach for IS quantification, it requires dedicated equipment and expert skills and does not allow real-time analysis. In this pilot study, we implemented a fast and simple technology designed to determine serum indoxyl sulfate levels that can be integrated into clinical practice. Indoxyl sulfate was detected at the time of enrollment by Tandem MS from 25 HD patients and 20 healthy volunteers. Next, we used a derivatization reaction to transform the serum indoxyl sulfate into Indigo blue. Thanks to the spectral shift to blue, its quantity was measured by the colorimetric assay at a wavelength of 420-450 nm. The spectrophotometric analysis was able to discriminate the levels of IS between healthy subjects and HD patients corresponding to the LC-MS/MS. In addition, we found a strong linear relationship between indoxyl sulfate levels and Indigo levels between the two methods (Tandem MS and spectrophotometry). This innovative method in the assessment of gut-derived indoxyl sulfate could represent a valid tool for clinicians to monitor CKD progression and dialysis efficacy.

Abstract
During the past decades, the gut microbiome emerged as a key player in kidney disease. Dysbiosis-related uremic toxins together with pro-inflammatory mediators are the main factors in a deteriorating kidney function. The toxicity of uremic compounds has been well-documented in a plethora of pathophysiological mechanisms in kidney disease, such as cardiovascular injury (CVI), metabolic dysfunction, and inflammation. Accumulating data on the detrimental effect of uremic solutes in kidney disease supported the development of many strategies to restore eubiosis. Fecal microbiota transplantation (FMT) spread as an encouraging treatment for different dysbiosis-associated disorders. In this scenario, flourishing studies indicate that fecal transplantation could represent a novel treatment to reduce the uremic toxins accumulation. Here, we present the state-of-the-art concerning the application of FMT on kidney disease to restore eubiosis and reverse the retention of uremic toxins.

Abstract
Acute kidney injury (AKI) is a common consequence of sepsis with a mortality rate of up to 40%. The pathogenesis of septic AKI is complex and involves several mechanisms leading to exacerbated inflammatory response associated with renal injury. A large body of evidence suggests that inflammation is tightly linked to AKI through bidirectional interaction between renal and immune cells. Preclinical data from our and other laboratories have identified in complement system activation a crucial mediator of AKI. Partial recovery following AKI could lead to long-term consequences that predispose to chronic dysfunction and may also accelerate the progression of preexisting chronic kidney disease. Recent findings have revealed striking morphological and functional changes in renal parenchymal cells induced by mitochondrial dysfunction, cell cycle arrest via the activation of signaling pathways involved in aging process, microvascular rarefaction, and early fibrosis. Although major advances have been made in our understanding of the pathophysiology of AKI, there are no available preventive and therapeutic strategies in this field. The identification of ideal clinical biomarkers for AKI enables prompt and effective therapeutic strategy that could prevent the progression of renal injury and promote repair process. Therefore, the use of novel biomarkers associated with clinical and functional criteria could provide early interventions and better outcome. Several new drugs for AKI are currently being investigated; however, the complexity of this disease might explain the failure of pharmacological intervention targeting just one of the many systems involved. The hypothesis that blood purification could improve the outcome of septic AKI has attracted much attention. New relevant findings on the role of polymethylmethacrylate-based continuous veno-venous hemofiltration in septic AKI have been reported. Herein, we provide a comprehensive literature review on advances in the pathophysiology of septic AKI and potential therapeutic approaches in this field.

Abstract
Several insults can lead to acute kidney injury (AKI) in native kidney and transplant patients, with diabetes critically contributing as pivotal risk factor. High glucose per se can disrupt several signaling pathways within the kidney that, if not restored, can favor the instauration of mechanisms of maladaptive repair, altering kidney homeostasis and proper function. Diabetic kidneys frequently show reduced oxygenation, vascular damage and enhanced inflammatory response, features that increase the kidney vulnerability to hypoxia. Importantly, epidemiologic data shows that previous episodes of AKI increase susceptibility to diabetic kidney disease (DKD), and that patients with DKD and history of AKI have a generally worse prognosis compared to DKD patients without AKI; it is therefore crucial to monitor diabetic patients for AKI. In the present review, we will describe the causes that contribute to increased susceptibility to AKI in diabetes, with focus on the molecular mechanisms that occur during hyperglycemia and how these mechanisms expose the different types of resident renal cells to be more vulnerable to maladaptive repair during AKI (contrast- and drug-induced AKI). Finally, we will review the list of the existing candidate biomarkers of diagnosis and prognosis of AKI in patients with diabetes.

Abstract
Extracellular vesicles (EV) are emerging mediators in several diseases. However, their role in the pathophysiology of antibody-mediated allograft rejection (AMR) has been poorly investigated. Here, we investigated the role of EV isolated from AMR patients in inducing tubular senescence and endothelial to mesenchymal transition (EndMT) and analyzed their miRNA expression profile. By multiplex bead flow cytometry, we characterized the immunophenotype of plasma AMR-derived EV and found a prevalent platelet and endothelial cell origin. In vitro, AMR-derived EV induced tubular senescence by upregulating SA-β Gal and CDKN1A mRNA. Furthermore, AMR-derived EV induced EndMT. The occurrence of tubular senescence and EndMT was confirmed by analysis of renal biopsies from the same AMR patients. Moreover, AMR-derived EV induced C3 gene upregulation and CFH downregulation in tubular epithelial cells, with C4d deposition on endothelial cells. Interestingly, RNase-mediated digestion of EV cargo completely abrogated tubular senescence and EndMT. By microarray analysis, miR-604, miR-515-3p, miR-let-7d-5p, and miR-590-3p were significantly upregulated in EV from AMR group compared with transplant controls, whereas miR-24-3p and miR-29a-3p were downregulated. Therefore, EV-associated miRNA could act as active player in AMR pathogenesis, unraveling potential mechanisms of accelerated graft senescence, complement activation and early fibrosis that might lead to new therapeutic intervention.

Abstract
The long non-coding RNAs (lncRNA) play an important role in several biological processes including some renal diseases. Nevertheless, little is known on lncRNA that are expressed in healthy kidney and involved in renal cell homeostasis and development, and even less is known about lncRNA involved in the maintenance of human adult renal stem/progenitor cells (ARPCs) that have been shown to be very important for renal homeostasis and repair processes. Through a whole genome transcriptome screening, we found that the HOTAIR lncRNA is highly expressed in renal progenitors and potentially involved in cell cycle and senescence biological processes. By CRISPR/Cas9 genome editing, we generated HOTAIR knock-out ARPC lines and established a key role of this lncRNA in ARPC self-renewal properties by sustaining their proliferative capacity and limiting the apoptotic process. Intriguingly, the HOTAIR knock-out led to the ARPC senescence and to a significant decrease of the CD133 stem cell marker expression, that is an inverse marker of ARPC senescence and can regulate renal tubular repair after the damage. Furthermore, we found that ARPCs expressed high levels of the α-Klotho anti-aging protein and especially 2.6-fold higher levels compared to that secreted by renal proximal tubular cells (RPTECs). Finally, we showed that HOTAIR exerts its function through the epigenetic silencing of the cell cycle inhibitor p15 inducing the trimethylation of the histone H3K27. Altogether, these results shed new light on the mechanisms of regulation of these important renal cells and may support the future development of precision therapies for kidney diseases.

Abstract
Obesity is the epidemic of our era and its incidence is supposed to increase by more than 30% by 2030. It is commonly defined as a chronic and metabolic disease with an excessive accumulation of body fat in relation to fat-free mass, both in terms of quantity and distribution at specific points on the body. The effects of obesity have an important impact on different clinical areas, particularly endocrinology, cardiology, and nephrology. Indeed, increased rates of obesity have been associated with increased risk of cardiovascular disease (CVD), cancer, type 2 diabetes (T2D), dyslipidemia, hypertension, renal diseases, and neurocognitive impairment. Obesity-related chronic kidney disease (CKD) has been ascribed to intrarenal fat accumulation along the proximal tubule, glomeruli, renal sinus, and around the kidney capsule, and to hemodynamic changes with hyperfiltration, albuminuria, and impaired glomerular filtration rate. In addition, hypertension, dyslipidemia, and diabetes, which arise as a consequence of overweight, contribute to amplifying renal dysfunction in both the native and transplanted kidney. Overall, several mechanisms are closely related to the onset and progression of CKD in the general population, including changes in renal hemodynamics, neurohumoral pathways, renal adiposity, local and systemic inflammation, dysbiosis of microbiota, insulin resistance, and fibrotic process. Unfortunately, there are no clinical practice guidelines for the management of patients with obesity-related CKD. Therefore, dietary management is based on the clinical practice guidelines for the nutritional care of adults with CKD, developed and published by the National Kidney Foundation, Kidney Disease Outcome Quality Initiative and common recommendations for the healthy population. Optimal nutritional management of these patients should follow the guidelines of the Mediterranean diet, which is known to be associated with a lower incidence of CVD and beneficial effects on chronic diseases such as diabetes, obesity, and cognitive health. Mediterranean-style diets are often unsuccessful in promoting efficient weight loss, especially in patients with altered glucose metabolism. For this purpose, this review also discusses the use of non-classical weight loss approaches in CKD, including intermittent fasting and ketogenic diet to contrast the onset and progression of obesity-related CKD.

Abstract
Abstract
BACKGROUND AND AIMS
The complex system of human adult renal stem/progenitor cells (ARPCs) and their crucial role in the renewal of epithelial renal cells and regenerative processes in the adult kidneys have been recently discovered. In the human kidney, CD133+/CD24+ ARPCs are present within different segments of the nephron as a population with epithelial expansion, self-renewal and differentiation capabilities. Understanding the factors that regulate the ARPCs behaviour is fundamental to completely take advantage of their potential and to develop treatments for renal injury.
Recent studies showed that long no-coding RNA (lncRNAs) are essential to establish developmental patterning and maintain the stem cell pluripotency network, further underscoring their important role in stem cell biology/technology and cellular reprogramming. lncRNAs can be dysregulated in different types of diseases and can also modulate the cellular senescence processes.
For the first time, we studied their function in ARPCs showing that they express high levels of a particular lncRNA, HOTAIR, influencing cell senescence.
METHOD
Whole-genome lncRNA expression was performed by Agilent microarray. lncRNA expression was validated by real-time PCR. CRISPR/Cas9 system has been used to knock-down HOTAIR lncRNA. SA-β-Gal experiments were used to evaluate cellular senescence in normal ARPCs and ARPCs knock-out for HOTAIR. By ELISA, it was evaluated the expression of secreted anti-ageing protein Klotho. Fluorescence-activated cell sorting (FACS) was applied to measure CD133 and protein p15 expression in normal and transfected cells. Chromatin immunoprecipitation assay (ChIP) was used to evaluate H3K27me3 in the promoter of p15.
RESULTS
We studied the lncRNA profile of renal proximal tubular cells (RPTEC) and tubular ARPCs. We found 611 lncRNAs specifically expressed in ARPCs compared with RPTECs (Fold Change > 2; FDR < 0.05). Among the most significantly modulated lncRNAs, we demonstrated that the lncRNA HOX Transcript Antisense RNA (HOTAIR) is highly expressed in ARPCs (Fold change = 15; P < 0.001). To study the functions related to the ARPCs properties, knock-out cell lines for HOTAIR were created by the CRISPR/Cas9 technique. The silenced lines for HOTAIR immediately assumed a senescent phenotype confirmed by the beta-galactosidase assay and decreased proliferation (proliferation rate of ˂60%, P < 0.001). Moreover, we found that the constitutional, functional and inverse-senescence marker CD133+ was downregulated in knock-out cells (Fold change = 15; P < 0.01). We then studied the secreted levels of the anti-ageing protein α-Klotho which is essential to the maintenance of normal renal function and has potential clinical applications in the diagnosis of acute renal failure (AKI) and chronic kidney disease (CKD).
We discovered that ARPCs produce α-Klotho at much higher levels compared to RPTEC, at a mean concentration of 200 pg/mL versus 33 pg/mL (Fold increase = 6.6; P < 0.001). Interestingly, following the HOTAIR knock-out, the levels of α-Klotho secreted by the ARPCs dropped sharply, with a 4-fold decrease (P < .001). In addition, we found that HOTAIR was responsible for the ARPC self-renewal through the epigenetic induction of the cell cycle inhibitor p15 through the trimethylation of histone H3K27 associated with the promoter region of p15. In ARPCs knock-out for HOTAIR p15 increased significantly (Fold increase = 3; P < 0.005) and the H3K27me3 in the promoter of p15 was less enriched (Fold decrease = 1.5; P < 0.05), leading to the increase of the cell cycle inhibitor and cell senescence.
CONCLUSION
These data demonstrated that HOTAIR regulates the self-renewal capacity of ARPCs and prevents them from becoming senescent in the short term. Moreover, HOTAIR influences ARPC ability to secrete high levels of α-Klotho, and those renal progenitors, through α-Klotho secretion, are able to influence its levels in surrounding tissues and to modulate, therefore, kidney ageing.

Abstract
Abstract
BACKGROUND AND AIMS
Replication of the enveloped SARS-COV2 virus can alter lipidomic composition and metabolism of infected cells [1]. These alterations commonly result in a decline in HDL, total cholesterol and LDL, and an increase in triglyceride levels in COVID-19 patients. Furthermore, the ‘cytokine storm’ subsequent to release of inflammatory cytokines can severely impair lipid homeostasis. Importantly, decreased HDL-cholesterol correlates with severity of COVID-19 infection and represents a significant prognostic factor in predicting poor clinical outcomes [2]. Similarly, it has been observed that COVID-19 patients’ recovery is accompanied by a rise in serum HDL levels. Pharmacological intervention that aims to restore ApoA-1 or functional HDL particles may have beneficial roles for clinical outcome of COVID-19 patients and has recently been approved for compassionate use [3].
SARS-CoV 2 spike proteins S1 and S2 can bind free cholesterol and HDL-bound cholesterol, facilitating virus entry by binding the ACE2 co-receptor Scavenger Receptor-BI (SR-BI) [4]. When activated at the trans-membrane level, SR-BI signalling culminates in Ser1173-eNOS phosphorylation with both anti-inflammatory and anti-apoptotic effect. We hypothesized that SARS-COV2 binding promoted SR-BI internalization, so that it could not exert its essential protective function. Therefore, the aim of this study is to evaluate the effects of CER-001, a mimetic HDL, in antagonizing this process.
METHOD
Endothelial and tubular (RPTEC) cells were exposed to S1, S2 and S1 + S2 (50–250 nM) with or without CER-001 (CER-001 50–500 ug/mL) and cholesterol (10–50 uM). Apoptosis tests (MTT and AnnV/PI) were performed. Internalization of SR-BI, ACE2 with S1 and activation of eNOS was evaluated by FACS analysis. SR-BI and ACE2 expression were evaluated on kidney biopsies from COVID-19 patients.
RESULTS
At concentrations used, the exposition of S1, S2 and S1 + S2 in the presence of CER-001 and cholesterol did not induce apoptosis of endothelial cells and RPTEC. Endothelial and tubular cells stimulated by S1, in presence of cholesterol, showed an increased intracellular level of SR-BI and ACE-2, with significantly reduced eNOS phosphorylation compared to baseline (P < 0.05). The treatment with CER-001 reversed trans-membrane SR-BI levels and eNOS phosphorylation to baseline values. The detection of S1 spike protein by endothelial cells immunohistochemistry revealed an increased level in S1-exposed cells with cholesterol and reduced S1 intracellular positive staining in CER-001-exposed cells (P < 0.05). Interestingly, S1-exposed cells without cholesterol appeared not to be capable of mediating S1 spike protein internalization.
Consistent with in vitro results, analysis of renal biopsies from COVID-19 patients with proteinuria showed increased SR-BI and ACE-2 cytoplasmic signals and reduced expression at the apical domain of injured tubules.
CONCLUSION
Our data confirmed the key role of lipid profile in SARS-COV2 infection, evaluating the molecular signalling involved in HDL metabolism and inflammatory processes, and could offer new therapeutic strategies for COVID-19 patients.

Abstract
BACKGROUND AND AIMS Several models have been proposed to describe the pathogenesis of Immunoglobulin A nephropathy (IgAN) and, among them, the multihit model where the gut-microbiota may play an important role. These models explain the pathogenesis of IgAN caused by the production of aberrant IgA, but it is believed that further predisposing factors are present, including immunological, genetic, environmental or nutritional factors. Recently, the role of IL-6 in IgAN pathogenesis is becoming increasingly important. It is essential for the deposition of glomerular immunoglobulin A and the development of renal disease in Cd37-deficient mice, although the pathogenetic mechanisms that determine its increase are not well known. A possible hypothesis emerges from our recent work on genome-wide DNA methylation screening in patients with IgAN, which identified, among other findings, a hypermethylated region comprising Vault 2–1 RNA (VTRNA2-1), a non-RNA coding also known as a precursor of miR-886 (pre-mi-RNA). Consistently, VTRNA2-1 expression was found downregulated in IgAN patients. Here we studied the involvement of the VTRNA2-1/PKR/CREB/IL-6 pathway in IgAN. METHOD Total RNA were isolated from PBMCs of IgAN patients, transplanted IgAN patients (TP-IgAN), non-IgAN transplanted patients (TP) and healthy subjects (HS). VTRNA2-1, CREB and PKR transcripts were evaluated by RT-PCR. Total and phosphorylated PKR, CREB and Il-6 proteins were evaluated by ELISA. Poly (I: C), a synthetic analogue of dsRNA and Pfizer-BioNTech COVID-19 COMIRNATY vaccine were used to transfect patient PBMCs. PKR inhibitor imoxin (C16) 1 µM was used to stimulate patient PBMCs. RESULTS Here we confirm that VTRNA2-1 transcript was down-regulated in native and transplanted IgAN subjects compared to HS and non IgAN transplanted patients, with a decrease of 30- and 100-folds, respectively (P < 0.05, and P < 0.0001). IgAN patients with downregulated VTRNA2-1 showed a PKR overactivation (fold increase of phosphorilation of 2.6- in IgAN and 2-folds in TP-IgAN patients; P < 0.05), coherently with the role played by VTRNA2-1 that binds to PKR and inhibits its phosphorylation. Then, we found that PKR causes the activation of CREB, a classical cAMP-inducible CRE-binding factor (fold increase of phosphorilation of 3- in IgAN and 2.67-folds in TP-IgAN patients; P < 0.01). CREB, interacting with a region of the IL-6 promoter, led to IL-6 production. Indeed, in IgAN patients we showed a IL-6 mean increase to 120 pg/mL compared to the respective controls (P < 0.05). Moreover, the IL-6 levels correlated with CREB and PKR phosphorylation (r = 0.97; P = 0.0006 and r = 0.89; P = 0.0064, respectively, for IgAN and TP-IgAN patients). Since PKR is normally activated by bacterial and viral RNA, we hypothesized that these microorganisms can further activate the PKR/CREB/IL-6 pathway leading to an excess of IL-6 production. This may explain both the high levels of IL-6, and infection involvement in the disease, and cases of IgAN associated with COVID-19 infection or with COVID-19 RNA-vaccination, and recent data showing microbiota involvement in IgAN. Effectively, we found that IgAN PMBCs stimulated with RNA poly(I: C) or the COVID-19 RNA-vaccine showed a significant increase in IL-6 levels compared to not-stimulated PBMCs (P < 0.05), supporting the pathogentic role played by viral RNA in IgAN pathogenesis and explaining the cases of IgAN patients developing episodes of macrohematuria after a COVID-19 infection or vaccination. Finally, we showed that the IL-6 secretion can be reduced by the PKR inhibitor imoxin (fold decrease of 5-folds in IgAN and TP-IgAN patients; P < 0.05). CONCLUSION In conclusion, the discovery of the upregulated VTRNA2-1/PKR/CREB/IL-6 pathway in IgAN patients may provide a new pathogenic mechanism in IgAN and may be useful for the development of novel therapeutic approaches, likely by modulating the VTRNA2-1 methylation level in IgAN patients.

Abstract
Acute kidney injury is a frequent complication of hospitalized patients and significantly increases morbidity and mortality, worsening costs and length of hospital stay. Despite this impact on healthcare system, treatment still remains only supportive (dialysis). Stem cell-derived extracellular vesicles are a promising option as they recapitulate stem cells properties, overcoming safety issues related to risks or rejection or aberrant differentiation. A growing body of evidence based on pre-clinical studies suggests that extracellular vesicles may be effective to treat acute kidney injury and to limit fibrosis through direct interference with pathogenic mechanisms of vascular and tubular epithelial cell damage. We herein analyze the state-of-the-art knowledge of therapeutic approaches with stem cell-derived extracellular vesicles for different forms of acute kidney injury (toxic, ischemic or septic) dissecting their cytoprotective, regenerative and immunomodulatory properties. We also analyze the potential impact of extracellular vesicles on the mechanisms of transition from acute kidney injury to chronic kidney disease, with a focus on the pivotal role of the inhibition of complement cascade in this setting. Despite some technical limits, nowadays the development of therapies based on stem cell-derived extracellular vesicles holds promise as a new frontier to limit acute kidney injury onset and progression.

Abstract
Our immune system actively fights bacteria and viruses, and it must strike a delicate balance between over- and under-reaction, just like Daedalus and Icarus in Greek mythology, who could not escape their imprisonment by flying too high or too low. Both human amniotic epithelial and mesenchymal stromal cells and the conditioned medium generated from their culture exert multiple immunosuppressive activities. They have strong immunomodulatory properties that are influenced by the types and intensity of inflammatory stimuli present in the microenvironment. Notably, very recently, the immunomodulatory activity of human adult renal stem/progenitor cells (ARPCs) has been discovered. ARPCs cause a decrease in Tregs and CD3+ CD4- CD8- (DN) T cells in the early stages of inflammation, encouraging inflammation, and an increase in the late stages of inflammation, favoring inflammation quenching. If the inflammatory trigger continues, however, ARPCs cause a further increase in DN T cells to avoid the development of a harmful inflammatory state. As in the flight of Daedalus and Icarus, who could not fly too high or too low to not destroy their wings by the heat of the sun or the humidity of the sea, in response to an inflammatory environment, stem cells seem to behave by paying attention to regulating T cells in the balance between immune tolerance and autoimmunity. Recognizing the existence of both suppressive and stimulatory properties, and the mechanisms that underpin the duality of immune reaction, will aid in the development of active immunotherapeutic approaches that manipulate the immune system to achieve therapeutic benefit.

Abstract
Background Data from large cardiac surgery registries have been depicting a downward trend of mortality and morbidities in the last 20 years. However, despite decades of medical evolution, cardiac surgery and cardiopulmonary bypass still provoke a systemic inflammatory response, which occasionally leads to worsened outcome. This article seeks to outline the mechanism of the phenomenon. Methods A thorough review of the literature has been performed. Criteria for considering studies for this non‐systematic review were as follows: observational and interventional studies investigating the systemic inflammatory response to cardiac surgery, experimental studies describing relevant molecular mechanisms, and essential review studies pertinent to the topic. Results The intrinsic variability of the inflammatory response to cardiac surgery, together with its heterogenous perception among clinicians, as well as the arduousness to early discriminate high‐responder patients from those who will not develop a clinically relevant reaction, concurred to hitherto unconclusive randomized controlled trials. Furthermore, peremptory knowledge about the pathophysiology of maladaptive inflammation following heart surgery is still lacking. Conclusions Systemic inflammation following cardiac surgery is a frequent entity that occasionally becomes clinically relevant. Specific genomic differences, age, and other preoperative factors influence the magnitude of the response, which elements display extreme redundancy and pleiotropism that the target of a single pathway cannot represent a silver bullet.

Abstract
Nowadays, it is clear that adult stem cells, also called as tissue stem cells, play a central role to repair and maintain the tissue in which they reside by their self-renewal ability and capacity of differentiating into distinct and specialized cells. As stem cells age, their renewal ability declines and their capacity to maintain organ homeostasis and regeneration is impaired. From a molecular perspective, these changes in stem cells properties can be due to several types of cell intrinsic injury and DNA aberrant alteration (i.e epigenomic profile) as well as changes in the tissue microenviroment, both into the niche and by systemic circulating factors. Strikingly, it has been suggested that aging-induced deterioration of stem cell functions may play a key role in the pathophysiology of the various aging-associated disorders. Therefore, understanding how resident stem cell age and affects near and distant tissues is fundamental. Here, we examine the current knowledge about aging mechanisms in several kinds of adult stem cells under physiological and pathological conditions and the principal aging-related changes in number, function and phenotype that determine the loss of tissue renewal properties. Furthermore, we examine the possible cell rejuvenation strategies. Stem cell rejuvenation may reverse the aging phenotype and the discovery of effective methods for inducing and differentiating pluripotent stem cells for cell replacement therapies could open up new possibilities for treating age-related diseases.

Abstract
For decades, the complement system, the central pillar of innate immune response, was recognized as a protective mechanism against cancer cells and the manipulation of complement effector functions in cancer setting offered a great opportunity to improve monoclonal antibody-based cancer immunotherapies. Similarly, cellular senescence, the process of cell cycle arrest that allow DNA and tissue repair has been traditionally thought to be able to suppress tumor progression. However, in recent years, extensive research has identified the complement system and cellular senescence as two main inducers of tumour growth in the context of chronic, persistent inflammation named inflammaging. Here, we discuss the data describing the ambivalent role of senescence in cancer with a particular focus on tumors that are strongly dependent on complement activation and can be understood by a new, senescence-related point of view: prostate cancer and renal cell carcinoma.

Abstract
Donor organ shortage still remains a serious obstacle for the access of wait-list patients to kidney transplantation, the best treatment for End-Stage Kidney Disease (ESKD). To expand the number of transplants, the use of lower quality organs from older ECD or DCD donors has become an established routine but at the price of increased incidence of Primary Non-Function, Delay Graft Function and lower-long term graft survival. In the last years, several improvements have been made in the field of renal transplantation from surgical procedure to preservation strategies. To improve renal outcomes, research has focused on development of innovative and dynamic preservation techniques, in order to assess graft function and promote regeneration by pharmacological intervention before transplantation. This review provides an overview of the current knowledge of these new preservation strategies by machine perfusions and pharmacological interventions at different timing possibilities: in the organ donor, ex-vivo during perfusion machine reconditioning or after implementation in the recipient. We will report therapies as anti-oxidant and anti-inflammatory agents, senolytics agents, complement inhibitors, HDL, siRNA and H2S supplementation. Renal delivery of pharmacologic agents during preservation state provides a window of opportunity to treat the organ in an isolated manner and a crucial route of administration. Even if few studies have been reported of transplantation after ex-vivo drugs administration, targeting the biological pathway associated to kidney failure (i.e. oxidative stress, complement system, fibrosis) might be a promising therapeutic strategy to improve the quality of various donor organs and expand organ availability.

Abstract
High-density lipoproteins (HDLs) are a class of blood particles, principally involved in mediating reverse cholesterol transport from peripheral tissue to liver. Omics approaches have identified crucial mediators in the HDL proteomic and lipidomic profile, which are involved in distinct pleiotropic functions. Besides their role as cholesterol transporter, HDLs display anti-inflammatory, anti-apoptotic, anti-thrombotic, and anti-infection properties. Experimental and clinical studies have unveiled significant changes in both HDL serum amount and composition that lead to dysregulated host immune response and endothelial dysfunction in the course of sepsis. Most SARS-Coronavirus-2-infected patients admitted to the intensive care unit showed common features of sepsis disease, such as the overwhelmed systemic inflammatory response and the alterations in serum lipid profile. Despite relevant advances, episodes of mild to moderate acute kidney injury (AKI), occurring during systemic inflammatory diseases, are associated with long-term complications, and high risk of mortality. The multi-faceted relationship of kidney dysfunction with dyslipidemia and inflammation encourages to deepen the clarification of the mechanisms connecting these elements. This review analyzes the multifaced roles of HDL in inflammatory diseases, the renal involvement in lipid metabolism, and the novel potential HDL-based therapies.

Abstract
Delayed Graft Function (DGF) is one of the most common early complications in kidney transplantation, associated with poor graft outcomes, prolonged post-operative hospitalization and higher rejection rates. Given the severe shortage of high-quality organs for transplantation, DGF incidence is expected to raise in the next years because of the use of nonstandard kidneys from Extended Criteria Donors (ECD) and from Donors after Circulatory Death (DCD). Alongside conventional methods for the evaluation of renal allograft [e.g. serum creatinine Glomerular Filtration Rate (GFR), needle biopsy], recent advancements in omics technologies, including proteomics, metabolomics and transcriptomics, may allow to discover novel biomarkers associated with DGF occurrence, in order to identify early preclinical signs of renal dysfunction and to improve the quality of graft management. Here, we gather contributions from basic scientists and clinical researchers to describe new omics studies in renal transplantation, reporting the emerging biomarkers of DGF that may implement and improve conventional approaches.

Abstract
Diabetic nephropathy (DN) is the most frequent cause of end-stage renal disease. Tubulointerstitial accumulation of lysine 63 (K63)-ubiquitinated (Ub) proteins is involved in the progression of DN fibrosis and correlates with urinary miR-27b-3p downregulation. We explored the renoprotective effect of an inhibitor of K63-Ub (NSC697923), alone or in combination with the ACE-inhibitor ramipril, in vitro and in vivo. Proximal tubular epithelial cells and diabetic DBA/2J mice were treated with NSC697923 and/or ramipril. K63-Ub protein accumulation along with α-SMA, collagen I and III, FSP-1, vimentin, p16INK4A expression, SA-α Gal staining, Sirius Red, and PAS staining were measured. Finally, we measured the urinary albumin to creatinine ratio (uACR), and urinary miR-27b-3p expression in mice. NSC697923, both alone and in association with ramipril, in vitro and in vivo inhibited hyperglycemia-induced epithelial to mesenchymal transition by significantly reducing K63-Ub proteins, α-SMA, collagen I, vimentin, FSP-1 expression, and collagen III along with tubulointerstitial and glomerular fibrosis. Treated mice also showed recovery of urinary miR-27b-3p and restored expression of p16INK4A. Moreover, NSC697923 in combination with ramipril demonstrated a trend in the reduction of uACR. In conclusion, we suggest that selective inhibition of K63-Ub, when combined with the conventional treatment with ACE inhibitors, might represent a novel treatment strategy to prevent the progression of fibrosis and proteinuria in diabetic nephropathy and we propose miR-27b-3p as a biomarker of treatment efficacy.

Abstract
The biological process of renal aging is characterized by progressive structural and functional deterioration of the kidney leading to end-stage renal disease, requiring renal replacement therapy. Since the discovery of pivotal mechanisms of senescence such as cell cycle arrest, apoptosis inhibition, and the development of a senescence-associated secretory phenotype (SASP), efforts in the understanding of how senescent cells participate in renal physiological and pathological aging have grown exponentially. This has been encouraged by both preclinical studies in animal models with senescent cell clearance or genetic depletion as well as due to evidence coming from the clinical oncologic experience. This review considers the molecular mechanism and pathways that trigger premature renal aging from mitochondrial dysfunction, epigenetic modifications to autophagy, DNA damage repair (DDR), and the involvement of extracellular vesicles. We also discuss the different pharmaceutical approaches to selectively target senescent cells (namely, senolytics) or the development of systemic SASP (called senomorphics) in basic models of CKD and clinical trials. Finally, an overview will be provided on the potential opportunities for their use in renal transplantation during ex vivo machine perfusion to improve the quality of the graft.

Abstract
Pentraxins are a family of evolutionarily conserved pattern recognition molecules with pivotal roles in innate immunity and inflammation, such as opsonization of pathogens during bacterial and viral infections. In particular, the long Pentraxin 3 (PTX3) has been shown to regulate several aspects of vascular and tissue inflammation during solid organ transplantation. Our study investigated the role of PTX3 as possible modulator of Complement activation in a swine model of renal ischemia/reperfusion (I/R) injury. We demonstrated that I/R injury induced early PTX3 deposits at peritubular and glomerular capillary levels. Confocal laser scanning microscopy revealed PTX3 deposits co-localizing with CD31+ endothelial cells. In addition, PTX3 was associated with infiltrating macrophages (CD163), dendritic cells (SWC3a) and myofibroblasts (FSP1). In particular, we demonstrated a significant PTX3-mediated activation of classical (C1q-mediated) and lectin (MBL-mediated) pathways of Complement. Interestingly, PTX3 deposits co-localized with activation of the terminal Complement complex (C5b-9) on endothelial cells, indicating that PTX3-mediated Complement activation occurred mainly at the renal vascular level. In conclusion, these data indicate that PTX3 might be a potential therapeutic target to prevent Complement-induced I/R injury.

Abstract
Sepsis-induced acute kidney injury (AKI) is a frequent complication in critically ill patients, refractory to conventional treatments. Aberrant activation of innate immune system may affect organ damage with poor prognosis for septic patients. Here, we investigated the efficacy of polymethyl methacrylate membrane (PMMA)-based continuous hemofiltration (CVVH) in modulating systemic and tissue immune activation in a swine model of LPS-induced AKI. After 3 h from LPS infusion, animals underwent to PMMA-CVVH or polysulfone (PS)-CVVH. Renal deposition of terminal complement mediator C5b-9 and of Pentraxin-3 (PTX3) deposits were evaluated on biopsies whereas systemic Complement activation was assessed by ELISA assay. Gene expression profile was performed from isolated peripheral blood mononuclear cells (PBMC) by microarrays and the results validated by Real-time PCR. Endotoxemic pigs presented oliguric AKI with increased tubulo-interstitial infiltrate, extensive collagen deposition, and glomerular thrombi; local PTX-3 and C5b-9 renal deposits and increased serum activation of classical and alternative Complement pathways were found in endotoxemic animals. PMMA-CVVH treatment significantly reduced tissue and systemic Complement activation limiting renal damage and fibrosis. By microarray analysis, we identified 711 and 913 differentially expressed genes with a fold change >2 and a false discovery rate <0.05 in endotoxemic pigs and PMMA-CVVH treated-animals, respectively. The most modulated genes were Granzyme B, Complement Factor B, Complement Component 4 Binding Protein Alpha, IL-12, and SERPINB-1 that were closely related to sepsis-induced immunological process. Our data suggest that PMMA-based CVVH can efficiently modulate immunological dysfunction in LPS-induced AKI.

Abstract
The pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease 2019 (COVID-19), resulting in acute respiratory disease, is a worldwide emergency. Because recently it has been found that SARS-CoV is dependent on host transcription factors (TF) to express the viral genes, efforts are required to understand the molecular interplay between virus and host response. By bioinformatic analysis, we investigated human TF that can bind the SARS-CoV-2 sequence and can be involved in viral transcription. In particular, we analysed the key role of TF involved in interferon (IFN) response. We found that several TF could be induced by the IFN antiviral response, specifically some induced by IFN-stimulated gene factor 3 (ISGF3) and by unphosphorylated ISGF3, which were found to promote the transcription of several viral open reading frame. Moreover, we found 22 TF binding sites present only in the sequence of virus infecting humans but not bat coronavirus RaTG13. The 22 TF are involved in IFN, retinoic acid signalling and regulation of transcription by RNA polymerase II, thus facilitating its own replication cycle. This mechanism, by competition, may steal the human TF involved in these processes, explaining SARS-CoV-2's disruption of IFN-I signalling in host cells and the mechanism of the SARS retinoic acid depletion syndrome leading to the cytokine storm. We identified three TF binding sites present exclusively in the Brazilian SARS-CoV-2 P.1 variant that may explain the higher severity of the respiratory syndrome. These data shed light on SARS-CoV-2 dependence from the host transcription machinery associated with IFN response and strengthen our knowledge of the virus's transcription and replicative activity, thus paving the way for new targets for drug design and therapeutic approaches.

Abstract
Adult Renal Stem/Progenitor Cells (ARPCs) have been recently identified in the human kidney and several studies show their active role in kidney repair processes during acute or chronic injury. However, little is known about their immunomodulatory properties and their capacity to regulate specific T cell subpopulations. We co-cultured ARPCs activated by triggering Toll-Like Receptor 2 (TLR2) with human peripheral blood mononuclear cells for 5 days and 15 days and studied their immunomodulatory capacity on T cell subpopulations. We found that activated-ARPCs were able to decrease T cell proliferation but did not affect CD8+ and CD4+ T cells. Instead, Tregs and CD3+ CD4- CD8- double-negative (DN) T cells decreased after 5 days and increased after 15 days of co-culture. In addition, we found that PAI1, MCP1, GM-CSF, and CXCL1 were significantly expressed by TLR2-activated ARPCs alone and were up-regulated in T cells co-cultured with activated ARPCs. The exogenous cocktail of cytokines was able to reproduce the immunomodulatory effects of the co-culture with activated ARPCs. These data showed that ARPCs can regulate immune response by inducing Tregs and DN T cells cell modulation, which are involved in the balance between immune tolerance and autoimmunity.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal agent of coronavirus disease 2019 (COVID-19), first emerged in Wuhan, China. The clinical manifestations of patients infected with COVID-19 include fever, cough, and dyspnea, up to acute respiratory distress syndrome (ARDS) and acute cardiac injury. Thus, a lot of severe patients had to be admitted to intensive care units (ICU). The pathogenic mechanisms of SARS-CoV-2 infection are mediated by the binding of SARS-CoV-2 spikes to the human angiotensin-converting enzyme 2 (ACE-2) receptor. The overexpression of human ACE-2 is associated with the disease severity in SARS-CoV-2 infection, demonstrating that viral entry into cells is a pivotal step. Although the lung is the organ that is most commonly affected by SARS-CoV-2 infection, acute kidney injury (AKI), heart dysfunction and abdominal pain are the most commonly reported co-morbidities of COVID-19. The occurrence of AKI in COVID-19 patients might be explained by several mechanisms that include viral cytopathic effects in renal cells and the host hyperinflammatory response. In addition, kidney dysfunction could exacerbate the inflammatory response started in the lungs and might cause further renal impairment and multi-organ failure. Mounting recent evidence supports the involvement of cardiovascular complications and endothelial dysfunction in COVID-19 syndrome, in addition to respiratory disease. To date, there is no vaccine, and no specific antiviral medicine has been shown to be effective in preventing or treating COVID-19. The removal of pro-inflammatory cytokines and the shutdown of the cytokine storm could ameliorate the clinical outcome in severe COVID-19 cases. Therefore, several interventions that inhibit viral replication and the systemic inflammatory response could modulate the severity of the renal dysfunction and increase the probability of a favorable outcome.

Abstract
Growing evidences suggest that peritubular capillaries pericytes are the main source of scar-forming myofibroblasts during chronic kidney disease (CKD), as well as early phases of acute kidney injury (AKI). In a swine model of sepsis and I/R (Ischemia Reperfusion) injury-induced AKI we demonstrated that renal pericytes are able to transdifferentiate toward α-SMA+ myofibroblasts leading to interstitial fibrosis. Even if precise pericytes identification requires transmission electron microscopy and the co-immunostaining of several markers (i.e., Gli, NG2 chondroitin sulphate proteoglycan, CD146, desmin or CD73) and emerging new markers (CD248 or TEM1, endosialin), previous studies suggested that PDGFR-β could be used as marker for renal pericytes characterization. Recently, double immunofluorescence staining of PDGFR-β and α-SMA was performed to identify the damage activated pericytes (PDGFR-β+/α-SMA+ cells) in the early phase of fibrosis development. Our data highlighted the crucial role of renal pericytes in the physiopathology of sepsis and I/R associated AKI. In this protocol, we describe the procedure for double immunofluorescence staining of PDGFR-β and α-SMA in swine Formalin-Fixed Paraffin-Embedded (FFPE) kidney biopsies and the method for image analysis and quantification.

Abstract
Background and Aims
The recent discovery of a complex system of human Adult renal stem/progenitor cells (ARPCs) dedicated to the renewal of epithelial renal cells has allowed scientists to better understand how the regenerative process can occur in the adult kidney. ARPCs have a great potential in view of developing future treatments for both acute and chronic renal injury. However, to completely take advantage of their capability it is essential to study the factors regulating the stem cell behavior. Recently, long noncoding RNAs (lncRNAs) have been recognized as a crucial class of gene expression regulators.
lncRNAs have several distinguishing characteristics that provide particular regulatory functions, including cell- and tissue-specific expression and the ability to transduce higher-order spatial information. Several lncRNAs modulate some somatic stem cell renewal or differentiation, while others promote a differentiation program. Their functions are often helped by proteic co-factor that convey the ability to activate or repress gene expression or to post-transcriptionally regulate other RNAs. Furthermore, numerous lncRNAs have been shown to act as competing endogenous RNAs, where the lncRNAs are proposed to bind to and compete miRNAs away from cognate mRNA targets. The aim of the study was to evaluate the basal expression profile of lncRNA expressed specifically in ARPCs.
Method
lncRNA expression profile was obtained from ARPCs and renal proximal tubular cells (RPTECs) alone or following cisplatin damage induction. We used Agilent SurePrint G3 Human Gene Expression Microarrays providing comprehensive coverage of genes and transcripts using the latest annotation databases. Genespring and R software were used for the analysis. lncRNA expression was validated by Real-time PCR. CrispR/Cas9 system has been used to knock-down specific lncRNA.
Results
We compared lncRNA expression between ARPCs and RPTECs: 45 lncRNA were differently modulated in ARPCs vs RPTECs (Fold change 1.5; FDR <0.05). In particular, we found 13 lncRNA upregulated and 32 lncRNA downregulated. Classification analysis showed that most of lncRNA modulated in ARPCs interfere with WNT signaling pathway, immune cell activation, and G-protein signaling pathway. Moreover, the overrepresentation test showed their involvement in calcium-mediated signaling, cell cycle and protein glycosylation processes (p<0.005). Among most significantly modulated lincRNAs we found HOTAIR and CCND2-AS1 that were upregulated in ARPCs compared to RPTECs. When we knocked-down the HOTAIR lncRNA ARPCs were not able to normally proliferate in cell culture. However, following cisplatin damage induced in RPTECs, ARPCs upregulated the LINC00511 and the miR210-HG. LINC00511 binds histone methyltransferase enhancer of zeste homolog 2 (EZH2, the catalytic subunit of the polycomb repressive complex 2 - PRC2), a highly conserved protein complex that regulates gene expression by methylating lysine 27 on histone H3. It acts as a modular scaffold of EZH2/PRC2 complexes, coordinates their localization, and specifies the histone modification pattern on the target genes, including p57. LINC00511 can affect cell proliferation, invasiveness, and apoptosis.
Conclusion
ARPCs express specific lncRNAs that could explain some of the ARPC stemness properties and their capacity to repair damage induced by cisplatin. Our findings suggest that lncRNA may represent a novel therapeutic target in acute and chronic renal injury.

Abstract
Background and Aims
EVs (Extracellular vesicles) are circulating microparticles able to mediate cell-to cell communication by carrying proteins, DNA, RNA or antibodies on their surface. EV are emerging as pivotal in renal Antibody-mediated rejection (AMR), one of the major causes of transplant failure associated to a massive complement activation. AMR is characterized by endothelial to mesenchymal transition (EndMT) and the occurrence of tubular accelerated senescence process, known as graft “Inflammaging”. However, the potential role of EVs in accelerating the renal aging and graft fibrosis after AMR is not well understood.
Method
Plasma EVs were isolated from 10 Acute AMR (AAMR), 10 Chronic AMR (CAMR) patients, 5 stable graft transplanted patients and 5 healthy volunteers. EVs were isolated by ultracentrifugation at 100.000 g for 1h at 4°C, quantified by Nanoparticle Tracking Analysis (Nanosight, NTA EV/ml) and characterized by FACS (Attune Nxt). RPTEC and endothelial cell culture were incubated with EVs (5e+4 EVs/cells target for 24h. MTT test was performed to assess cell viability. Cellular senescence was investigated by qPCR for p21, p53, Klotho and CYP1B1 and SA-β-gal staining were performed. To assess EndMT analysis for CD31, VE-cadherin, Vimentin, Collagen I was performed by FACS. mRNA level of C3 and CFH were also measured by qPCR and C4d deposits were evaluated in endothelial cell colture by IF. Renal biopsies were then analyzed for inflammaging (p16INK4a) and EndMT markers (CD31/αSMA) by IHC and IF.
Results
The Nanosight analysis showed significant differences in the amount of-EVs count per ml of plasma in AMR patients compared to healthy subjects. EVs appeared to be significantly augmented in acute AMR, in a higher manner than chronic AMR (NTA, p=0.0154). By cytofluorimetric analysis, the endothelial markers CD31 and VE- cadherin appeared to be significantly increased compared of healthy control, indicating a predominant endothelial EV origin (p<0.05). Furthermore, an increase for CD3, CD4, CD8, CD40 and CD40L lymphocyte/monocytes markers was found. In vitro, the exposure of RPTEC and endothelial cells to AMR-derived EVs did not induce the loss of cell proliferation. However, AMR-derived EVs induced senescence in RPTEC, as observed by increase in SA-β-gal positive cells, upregulation of p21, p53, CYP1B1 and downregulated KL gene expression (p<0.05). EVs induced the EndMT as observed by FACS with the downregulation of CD31, VE-cadherin (CD144) and increase of Vimentin and Collagen I (p=0.025). To evaluate the contribution of EVs to local complement activation, C3 and CFH qPCR analysis were performed. EVs from AMR patients induced a significant increase in C3 gene expression with concomitant downregulation in CFH in RPTEC. EV exposition induced the classical and lectin pathway activation in endothelial culture medium, and C4d deposition. These data support the hypothesis that circulating EVs can amplify local complement activation in systemic endothelial and tubular cells during AMR, therefore leading to accelerated senescence and fibrosis as later effects. Finally, renal AMR biopsies showed significant tubular senescence as indicated by p16 expression; p16 was significantly upregulated in Chronic compared with Acute AMR biopsies (p<0.05). The AMR biopsies showed positivity for EndMT, as indicated by CD31 decrease and interstitial αSMA upregulation (p<0.05).
Conclusion
These results suggest a putative role for circulating AMR derived-EVs in inducing the tubular inflammaging by local complement activation and early fibrosis by EndMT. The EVs cargo characterization that is ongoing might highlight novel targets for therapeutic intervention.

Abstract
Background and Aims
Sepsis-induced acute kidney injury (AKI) is a growing health care problem, refractory to conventional treatments. This disease is characterized by an overwhelmed immune response against a primary insult that become responsible for renal dysfunction and poor outcome. Therapeutic strategies based on blood purification have been developed for the treatment of this disease. The use of polymethyl methacrylate (PMMA) membrane hemofilter in continuous hemodiafiltration (CHDF) modality showed better hemodynamic stability and efficient renal support in chronic dialysis maintenance. Here we investigated the efficacy of Hemofeel PMMA membrane (TORAY, Japan) in interfering with Complement activation and renal damage in a swine model of sepsis-induced AKI.
Method
After 3 hours from LPS infusion, 7 hours of PMMA-CVVH treatment or 7 hours of polysulfone (PSF)-CVVH were performed. Animals were sacrificed after 24h from LPS infusion. Histologic and renal function parameters were analyzed in all pigs. Pentraxin-3 (PTX3) and C5b-9 deposits were assessed on renal biopsies. Systemic Complement activation was evaluated by Wieslab kit. Gene expression profile was obtained from isolated PBMCs by Agilent SurePrint G3 Porcine Gene Expression Microarrays. Genespring and R software were used for the analysis. Results were validated by Real-time PCR.
Results
Analysis of renal biopsies from septic pigs presented increased interstitial leucocyte infiltrate, extensive collagen deposition and diffuse glomerular thrombi compared to healthy pigs (p<0.05). Confocal analysis showed extensive PTX-3 and C5-b9 deposits at tubulo-interstitial level associated with significant activation of systemic complement classical and alternative pathways (p<0.05). Interestingly, PMMA-CVVH treatment significantly reduced local and systemic complement activation, leucocyte infiltrate and tubule-interstitial fibrosis (p<0.05). On the contrary, no significant improvement was observed by PSF-CVVH treatment. Then, we compared the whole-genome gene expression profiles of swine PBMC. We identified 711 differentially expressed genes comparing PBMC before LPS infusion (LPS T0) and after 24 hours from LPS infusion (LPS T24) and 913 genes comparing gene expression profiles of LPS T24 group with that of septic pigs treated with PMMA-CVVH (PMMA T24 group) (fold change >2 ; false discovery rate <0.05). The most modulated genes were Granzime B, Complement Factor B, Complement Component 4 Binding Protein Alpha, IL-12, SERPINB-1 and TIMP-2 that were closely related to sepsis-induced immunological process. Finally, quantitative PCR confirmed the microarray data indicating that Granzime B and Complement Factor B upregulation in PBMC was significantly hampered by PMMA treatment.
Conclusion
Our data suggest that LPS induced AKI is characterized by activation of Classical and alternative Complement pathways resulting in significant renal tissue damage. By interfering with complement activation and inflammatory response, PMMA membrane might prevent dysfunctional activation of resident renal cells with prevention of sepsis-induced AKI.

Abstract
The aberrant activation of complement system in several kidney diseases suggests that this pillar of innate immunity has a critical role in the pathophysiology of renal damage of different etiologies. A growing body of experimental evidence indicates that complement activation contributes to the pathogenesis of acute kidney injury (AKI) such as delayed graft function (DGF) in transplant patients. AKI is characterized by the rapid loss of the kidney's excretory function and is a complex syndrome currently lacking a specific medical treatment to arrest or attenuate progression in chronic kidney disease (CKD). Recent evidence suggests that independently from the initial trigger (i.e., sepsis or ischemia/reperfusions injury), an episode of AKI is strongly associated with an increased risk of subsequent CKD. The AKI-to-CKD transition may involve a wide range of mechanisms including scar-forming myofibroblasts generated from different sources, microvascular rarefaction, mitochondrial dysfunction, or cell cycle arrest by the involvement of epigenetic, gene, and protein alterations leading to common final signaling pathways [i.e., transforming growth factor beta (TGF-β), p16 ink4a , Wnt/β-catenin pathway] involved in renal aging. Research in recent years has revealed that several stressors or complications such as rejection after renal transplantation can lead to accelerated renal aging with detrimental effects with the establishment of chronic proinflammatory cellular phenotypes within the kidney. Despite a greater understanding of these mechanisms, the role of complement system in the context of the AKI-to-CKD transition and renal inflammaging is still poorly explored. The purpose of this review is to summarize recent findings describing the role of complement in AKI-to-CKD transition. We will also address how and when complement inhibitors might be used to prevent AKI and CKD progression, therefore improving graft function.

Abstract
During sepsis, the increased synthesis of circulating lipopolysaccharide (LPS)-binding protein (LBP) activates LPS/TLR4 signaling in renal resident cells, leading to acute kidney injury (AKI). Pericytes are the major source of myofibroblasts during chronic kidney disease (CKD), but their involvement in AKI is poorly understood. Here, we investigate the occurrence of pericyte-to-myofibroblast trans-differentiation (PMT) in sepsis-induced AKI. In a swine model of sepsis-induced AKI, PMT was detected within 9 h from LPS injection, as evaluated by the reduction of physiologic PDGFRβ expression and the dysfunctional α-SMA increase in peritubular pericytes. The therapeutic intervention by citrate-based coupled plasma filtration adsorption (CPFA) significantly reduced LBP, TGF-β, and endothelin-1 (ET-1) serum levels, and furthermore preserved PDGFRβ and decreased α-SMA expression in renal biopsies. In vitro, both LPS and septic sera led to PMT with a significant increase in Collagen I synthesis and α-SMA reorganization in contractile fibers by both SMAD2/3-dependent and -independent TGF-β signaling. Interestingly, the removal of LBP from septic plasma inhibited PMT. Finally, LPS-stimulated pericytes secreted LBP and TGF-β and underwent PMT also upon TGF-β receptor-blocking, indicating the crucial pro-fibrotic role of TLR4 signaling. Our data demonstrate that the selective removal of LBP may represent a therapeutic option to prevent PMT and the development of acute renal fibrosis in sepsis-induced AKI.

Abstract
Endothelial dysfunction is a hallmark of LPS-induced acute kidney injury (AKI). Endothelial cells (ECs) acquired a fibroblast-like phenotype and contributed to myofibroblast generation through the endothelial-to-mesenchymal transition (EndMT) process. Of note, human adult renal stem/progenitor cells (ARPCs) enhance the tubular regenerative mechanism during AKI but little is known about their effects on ECs. Following LPS exposure, ECs proliferated, decreased EC markers CD31 and vascular endothelial cadherin, and up-regulated myofibroblast markers, collagen I, and vimentin. The coculture with ARPCs normalized the EC proliferation rate and abrogated the LPS-induced EndMT. The gene expression analysis showed that most of the genes modulated in LPS-stimulated ARPCs belong to cell activation and defense response pathways. We showed that the ARPC-specific antifibrotic effect is exerted by the secretion of CXCL6, SAA4, and BPIFA2 produced after the anaphylatoxin stimulation. Next, we investigated the molecular signaling that underlies the ARPC protective mechanism and found that renal progenitors diverge from differentiated tubular cells and ECs in myeloid differentiation primary response 88-independent pathway activation. Finally, in a swine model of LPS-induced AKI, we observed that activated ARPCs secreted CXCL6, SAA4, and BPIFA2 as a defense response. These data open new perspectives on the treatment of both sepsis- and endotoxemia-induced AKI, suggesting an underestimated role of ARPCs in preventing endothelial dysfunction and novel strategies to protect the endothelial compartment and promote kidney repair.-Sallustio, F., Stasi, A., Curci, C., Divella, C., Picerno, A., Franzin, R., De Palma, G., Rutigliano, M., Lucarelli, G., Battaglia, M., Staffieri, F., Crovace, A., Pertosa, G.

Abstract
Pericytes are one of the principal sources of scar-forming myofibroblasts in chronic kidneys disease. However, the modulation of pericyte-to-myofibroblast transdifferentiation (PMT) in the early phases of acute kidney injury is poorly understood. Here, we investigated the role of complement in inducing PMT after transplantation. Using a swine model of renal ischemia/reperfusion (I/R) injury, we found the occurrence of PMT after 24 h of I/R injury as demonstrated by reduction of PDGFRβ+/NG2+ cells with increase in myofibroblasts marker αSMA. In addition, PMT was associated with significant reduction in peritubular capillary luminal diameter. Treatment by C1-inhibitor (C1-INH) significantly preserved the phenotype of pericytes maintaining microvascular density and capillary lumen area at tubulointerstitial level. In vitro, C5a transdifferentiated human pericytes in myofibroblasts, with increased αSMA expression in stress fibers, collagen I production, and decreased antifibrotic protein Id2. The C5a-induced PMT was driven by extracellular signal-regulated kinases phosphorylation leading to increase in collagen I release that required both non-canonical and canonical TGFβ pathways. These results showed that pericytes are a pivotal target of complement activation leading to a profibrotic maladaptive cellular response. Our studies suggest that C1-INH may be a potential therapeutic strategy to counteract the development of PMT and capillary lumen reduction in I/R injury.
