Abstract
Acute kidney injury (AKI) is a common, multicause clinical condition that, if ignored, often progresses to chronic kidney disease (CKD) and end-stage kidney disease, with a mortality rate of 40-50%. However, there is a lack of universal treatment for AKI. Inflammation is the basic pathological change of early kidney injury, and inflammation can exacerbate AKI. Macrophages are the primary immune cells involved in the inflammatory microenvironment of kidney disease. Therefore, regulating the function of macrophages is a crucial breakthrough for the AKI intervention. Our team chemically modified pyxinol, an ocotillol-type ginsenoside, to prepare PJ16 with higher solubility and bioavailability. In vitro, using a model of macrophages stimulated by LPS, it was found that PJ16 could regulate macrophage function, including inhibiting the secretion of inflammatory factors, promoting phagocytosis, inhibiting M1 macrophages, and promoting M1 transition to the M2c macrophage. Further investigation revealed that PJ16 may shield renal tubular epithelial cells (HK-2) damaged by LPS in vitro. Based on this, PJ16 was validated in the animal model of unilateral ureteral obstruction, which showed that it improves renal function and inhibits renal tissue fibrosis by decreasing inflammatory responses, reducing macrophage inflammatory infiltration, and preferentially upregulating M2c macrophages. In conclusion, our study is the first to show that PJ16 resists AKI and fibrosis by mechanistically regulating macrophage function by modulating the phenotypic transition from M1 to M2 macrophages, mainly M2c macrophages.

Zinc Finger Protein BCL11A Contributes to the Abortive Infection of Hirame novirhabdovirus (HIRRV) in B Lymphocytes of Flounder (Paralichthys olivaceus). J Virol 2022; 96:e0147022.

Abstract
Hirame novirhabdovirus (HIRRV) infection is characterized by a pronounced viremia, and the high viral load is typically detected in immune-related organs and the circulatory system. In the present study, we demonstrated that HIRRV has the capacity to invade part of flounder membrane-bound IgM (mIgM+) B lymphocyte. Eight quantitative real-time PCR (qRT-PCR) standard curves involving HIRRV genomic RNA (gRNA), cRNA, and six mRNAs were established based on the strand-specific reverse transcription performed with tagged primers. It was revealed that viral RNA synthesis, especially the replication of gRNA, was inhibited in B cells, and the intracellular HIRRV even failed to produce infectious viral particles. Moreover, a range of genes with nucleic acid binding activity or related to viral infection were screened out based on the transcriptome analysis of HIRRV-infected B cells, and five molecules were further selected because of their different expression patterns in HIRRV-infected B cells and hirame natural embryo (HINAE) cells. The overexpression of these genes followed by HIRRV infection and RNA binding protein immunoprecipitation (RIP) assay revealed that the flounder B cell lymphoma/leukemia 11A (BCL11A), a highly conserved zinc finger transcription factor, is able to inhibit the proliferation of HIRRV by binding with full-length viral RNA mainly via its zinc finger domains at the C terminus. In conclusion, these data indicated that the high transcriptional activity of BCL11A in flounder mIgM+ B lymphocytes is a crucial factor for the abortive infection of HIRRV, and our findings provide new insights into the interaction between HIRRV and teleost B cells. IMPORTANCE HIRRV is a fish rhabdovirus that is considered as an important pathogen threatening the fish farming industry represented by flounder because of its high infectivity and fatality rate. To date, research toward understanding the complex pathogenic mechanism of HIRRV is still in its infancy and faces many challenges. Exploration of the relationship between HIRRV and its target cells is interesting and necessary. Here, we revealed that flounder mIgM+ B cells are capable of suppressing viral RNA synthesis and result in an unproductive infection of HIRRV. In addition, our results demonstrated that zinc finger protein BCL11A, a transcription factor in B cells, is able to suppress the replication of HIRRV. These findings increased our understanding of the underlying characteristics of HIRRV infection and revealed a novel antiviral mechanism against HIRRV based on the host restriction factor in teleost B cells, which sheds new light on the research into HIRRV control.

Impact of direct-acting antiviral regimens on hepatic and extrahepatic manifestations of hepatitis C virus infection. World J Hepatol 2022; 14:1053-1073.

Abstract
Hepatitis C virus (HCV) is a common cause of liver disease and is associated with various extrahepatic manifestations (EHMs). This mini-review outlines the currently available treatments for HCV infection and their prognostic effect on hepatic manifestations and EHMs. Direct-acting antiviral (DAA) regimens are considered pan-genotypic as they achieve a sustained virological response (SVR) > 85% after 12 wk through all the major HCV genotypes, with high percentages of SVR even in advanced fibrosis and cirrhosis. The risk factors for DAA failure include old males, cirrhosis, and the presence of resistance-associated substitutions (RAS) in the region targeted by the received DAAs. The effectiveness of DAA regimens is reduced in HCV genotype 3 with baseline RAS like A30K, Y93H, and P53del. Moreover, the European Association for the Study of the Liver recommended the identification of baseline RAS for HCV genotype 1a. The higher rate of hepatocellular carcinoma (HCC) after DAA therapy may be related to the fact that DAA regimens are offered to patients with advanced liver fibrosis and cirrhosis, where interferon was contraindicated to those patients. The change in the growth of pre-existing subclinical, undetectable HCC upon DAA treatment might be also a cause. Furthermore, after DAA therapy, the T cell-dependent immune response is much weaker upon HCV clearance, and the down-regulation of TNF-α or the elevated neutrophil to lymphocyte ratio might increase the risk of HCC. DAAs can result in reactivation of hepatitis B virus (HBV) in HCV co-infected patients. DAAs are effective in treating HCV-associated mixed cryoglobulinemia, with clinical and immunological responses, and have rapid and high effectiveness in thrombocytopenia. DAAs improve insulin resistance in 90% of patients, increase glomerular filtration rate, and decrease proteinuria, hematuria and articular manifestations. HCV clearance by DAAs allows a significant improvement in atherosclerosis and metabolic and immunological conditions, with a reduction of major cardiovascular events. They also improve physical function, fatigue, cognitive impairment, and quality of life. Early therapeutic approach with DAAs is recommended as it cure many of the EHMs that are still in a reversible stage and can prevent others that can develop due to delayed treatment.

Abstract
Lipid accumulation and inflammation act together to induce, sustain, and further development of chronic liver disease. Hepatitis C virus (HCV) infection induces metabolic and immune changes in liver macrophages, promoting lipid accumulation and inflammation that synergize and culminate in the development of steatohepatitis and fibrogenesis. Chronic HCV patients have increased liver macrophages with disruptions in cholesterol metabolism and alterations in inflammatory mediators. While HCV-induced changes in inflammatory mediators are well documented, how HCV triggers metabolic change in macrophages is unknown. In this report, we examined the mechanism of macrophage sensing of HCV to cause metabolic impairment and subsequent immune dysfunction. We demonstrate that HCV protein and RNA kinetics in macrophages are distinct from hepatocytes. In macrophages, HCV RNAs and protein accumulate rapidly after exposure but internalized RNAs quickly decline to a low-level set point. Notably, exposure of macrophages to HCV resulted in increased lipids and cholesterol and activation of cholesterol-sensing, immunomodulatory liver X receptors (LXRs). Furthermore, we provide evidence that HCV RNA accumulation in macrophages occurs through scavenging receptors. These results suggest that HCV released from infected hepatocytes stimulates accumulation of lipids and activation of LXR in macrophages contributing to metabolic changes involved in HCV-induced chronic liver disease. Our results provide novel insight into mechanisms through which impaired lipid metabolism in macrophages associated with HCV infection promotes development of liver steatohepatitis and fibrosis.

Abstract
Viral hepatitis B (HBV) and hepatitis C (HCV) infections remain the most common risk factors for the development of hepatocellular carcinoma (HCC), and their heterogeneous distribution influences the global prevalence of this common type of liver cancer. Typical hepatitis infection elicits various immune responses within the liver microenvironment, and viral persistence induces chronic liver inflammation and carcinogenesis. HBV is directly mutagenic but can also cause low-grade liver inflammation characterized by episodes of intermittent high-grade liver inflammation, liver fibrosis, and cirrhosis, which can progress to decompensated liver disease and HCC. Equally, the absence of key innate and adaptive immune responses in chronic HCV infection dampens viral eradication and induces an exhausted and immunosuppressive liver niche that favors HCC development and progression. The objectives of this review are to (i) discuss the epidemiological pattern of HBV and HCV infections, (ii) understand the host immune response to acute and chronic viral hepatitis, and (iii) explore the link between this diseased immune environment and the development and progression of HCC in preclinical models and HCC patients.

Abstract
An efficient compound enzyme extraction process was developed and optimized to extract the polysaccharide from Erythronium sibiricum bulb via response surface methodology. The polysaccharide E2P was obtained. Then, the preliminary characteristics of E2P were determined via colorimetry and chromatography. Additionally, the immunoregulatory activities of E2P and another polysaccharide (ESBP, extracted using the hot water method) were compared. The optimized extraction results were as follows: temperature (54.56 °C), time (2.52 h), pH (6.53), and enzyme concentration ratio (0.5% cellulase:1.5% amylase). The yield (64.18% ± 2.91%) obtained under the aforementioned conditions was considerably higher than the yield of ESBP (37.25% ± 0.17%). The total sugar, uronic acid, starch, and protein contents of E2P were 81.77% ± 2.84%, 3.31% ± 0.45%, 3.29% ± 0.01%, and 0.24% ± 0.02%, respectively. The HPLC result suggested that the predominant monosaccharides of E2P included glucose, galactose, and arabinose, with a molar ratio of 543.2:1:1.8. The in vitro tests in RAW264.7 cells indicated that ESBP exhibited better immunomodulatory activities than E2P. In particular, ESBP can promote the proliferation, phagocytosis, and cytokine secretion abilities of cytokines, such as nitric oxide, tumor necrosis factor-α, and interleukin (IL)-1β of RAW264.6 cells. By contrast, E2P can only promote phagocytosis ability and the secretion of IL-1β.

Abstract
The hepatitis C virus (HCV), an obligatory intracellular pathogen, highly depends on its host cells to propagate successfully. The HCV life cycle can be simply divided into several stages including viral entry, protein translation, RNA replication, viral assembly and release. Hundreds of cellular factors involved in the HCV life cycle have been identified over more than thirty years of research. Characterization of these cellular factors has provided extensive insight into HCV replication strategies. Some of these cellular factors are targets for anti-HCV therapies. In this review, we summarize the well-characterized and recently identified cellular factors functioning at each stage of the HCV life cycle.

Abstract
The present review describes the various roles of cyclodextrins (CDs) in vaccines against viruses and in antiviral therapeutics. The first section describes the most commonly studied application of cyclodextrins—solubilisation and stabilisation of antiviral drugs; some examples also refer to their beneficial taste-masking activity. The second part of the review describes the role of cyclodextrins in antiviral vaccine development and stabilisation, where they are employed as adjuvants and cryopreserving agents. In addition, cyclodextrin-based polymers as delivery systems for mRNA are currently under development. Lastly, the use of cyclodextrins as pharmaceutical active ingredients for the treatment of viral infections is explored. This new field of application is still taking its first steps. Nevertheless, promising results from the use of cyclodextrins as agents to treat other pathologies are encouraging. We present potential applications of the results reported in the literature and highlight the products that are already available on the market.

Abstract
BACKGROUND Chronic inflammation in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection increases cognitive impairment. With newer, direct-acting antiviral therapies for HCV, our objective was to determine whether chronic inflammation would be decreased and cognition improved with HCV sustained viral response (SVR) in coinfection. METHODS We studied 4 groups longitudinally: 7 HCV-monoinfected and 12 HIV/HCV-coinfected persons before and after treatment for HCV, 12 HIV-monoinfected persons, and 9 healthy controls. We measured monocyte activation and gene expression, monocyte-derived exosome micro-ribonucleic acid (miRNA) expression, plasma inflammation, and cognitive impairment before and after therapy. RESULTS Plasma soluble CD163 and neopterin were decreased in HCV mono- and coinfected persons. Blood CD16+ monocytes were decreased in coinfection after HCV treatment. Global deficit score improved 25% in coinfection with the visual learning/memory domain the most improved. Hepatitis C virus SVR decreased monocyte interferon genes MX1, IFI27, and CD169 in coinfection and MX1, LGALS3BP, and TNFAIP6 in HCV monoinfection. Monocyte exosomes from coinfected persons increased in microRNA (miR)-19a, miR-221, and miR-223, all of which were associated with decreasing inflammation and nuclear factor-κB activation. CONCLUSIONS Hepatitis C virus cure in coinfection brings monocyte activation to levels of HIV alone. Cognitive impairment is significantly improved with cure but not better than HIV infection alone, which strong suggests that cognitive impairment was driven by both HIV and HCV.SummaryHCV cure in HIV coinfection improves monocyte and plasma activation markers and increases cognitive function in the visual learning/memory domain.

Abstract
Hepatocellular carcinoma (HCC) has one of highest mortalities globally amongst cancers, but has limited therapeutic options once in the advanced stage. Hepatitis B or C virus infection are the most common drivers for HCC carcinogenesis, triggering chronic liver inflammation and adding to the complexity of the immune microecosystem of HCC. The emergence of immunotherapy has afforded a new avenue of therapeutic options for patients with advanced HCC with a history of hepatitis B or C virus infection. This article reviews the change of immunity elicited by hepatitis B or C virus infection, the immune feature of HCC, and the clinical evidence for immunotherapy in advanced HCC and discusses future directions in this field.

Abstract
Host defense against invading pathogens within the liver is dominated by innate immunity. Natural killer (NK) cells have been implicated at all stages of hepatitis C virus (HCV) infection, from providing innate protection to contributing to treatment-induced clearance. Decreased NK cell levels, altered NK cell subset distribution, activation marker expression, and functional polarization toward a cytolytic phenotype are hallmarks of chronic HCV infection. Interferon α (IFN-α) is a potent activator of NK cells; therefore, it is not surprising that NK cell activation has been identified as a key factor associated with sustained virological response (SVR) to IFN-α-based therapies. Understanding the role of NK cells, macrophages, and other innate immune cells post-SVR remains paramount for prevention of disease pathogenesis and progression. Novel strategies to treat liver disease may be aimed at targeting these cells.

Abstract
Follistatin-like protein 1 (FSTL1) is a pleiotropic cytokine involved in multiple processes including organ development, carcinogenesis, metastasis and so on. Some recent studies have suggested a possible role of FSTL1 in the inflammatory diseases. We for the first time tried to unravel its effect on the colitis, and explore the possible mechanisms. Here we found that FSTL1 was upregulated in active human and murine colitis. It facilitated proinflammatory M1 polarization of macrophages and inhibited the M2 anti-inflammatory phenotype, leading to excessive production of multiple inflammatory cytokines in vitro and in vivo. Haplodeletion of FSTL1 in mice significantly reduced the clinical and histological activity of colitis. Most importantly, macrophage depletion diminished the difference between DSS-treated WT and FSTL1+/- mice. Altogether, our results suggested that FSTL1 may also serve as an important contributor in the colonic inflammation. The possible mechanism may be related to its modulation on macrophage polarization.

A bioinformatics investigation into the pharmacological mechanisms of the effect of the Yinchenhao decoction on hepatitis C based on network pharmacology. BMC Complement Med Ther 2020; 20:50. [PMID: 32050950 PMCID: PMC7076901 DOI: 10.1186/s12906-020-2823-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2019] [Accepted: 01/20/2020] [Indexed: 12/29/2022] Open
Abstract
Background Globally, more than 170 million people are infected with hepatitis C virus, a major cause of cirrhosis and hepatocellular carcinoma. The Yinchenhao Decoction (YCHD) is a classic formula comprising three herbal medicines. This decoction have long been used in China for clinically treating acute and chronic infectious hepatitis and other liver and gallbladder damp heat-accumulation disorders. Methods In this study, we identified 32 active ingredients and 200 hepatitis C proteins and established a compound-predicted target network and a hepatitis C protein–protein interaction network by using Cytoscape 3.6.1. Then, we systematically analyzed the potential targets of the YCHD for the treatment of hepatitis C. Finally, molecular docking was applied to verify the key targets. In addition, we analyzed the mechanism of action of the predicted targets by the Kyoto Encyclopedia of Genes and Genomes and gene ontology analyses. Results This study adopted a network pharmacology approach, mainly comprising target prediction, network construction, module detection, functional enrichment analysis, and molecular docking to systematically investigate the mechanisms of action of the YCHD in hepatitis C. The targets of the YCHD in the treatment of hepatitis C mainly involved PIK3CG, CASP3, BCL2, CASP8, and MMP1. The module and pathway enrichment analyses showed that the YCHD had the potential to influence varieties of biological pathways, including the TNF signaling pathway, Ras signaling pathway, PI3K-Akt signaling pathway, FoxO signaling pathway, and pathways in cancer, that play an important role in the pathogenesis of hepatitis C. Conclusion The results of this study preliminarily verified the basic pharmacological effects and related mechanisms of the YCHD in the treatment of hepatitis C.

Abstract
Cyclodextrins, since their discovery in the late 19th century, were mainly regarded as excipients. Nevertheless, developments in cyclodextrin research have shown that some of these hosts can capture and include biomolecules, highlighting fatty acids and cholesterol, which implies that they are not inert and that their action may be used in specific medicinal purposes. The present review, centered on literature reports from the year 2000 until the present day, presents a comprehensive description of the known biological activities of cyclodextrins and their implications for medicinal applications. The paper is divided into two main sections, one devoted to the properties and applications of cyclodextrins as active pharmaceutical ingredients in a variety of pathologies, from infectious ailments to cardiovascular dysfunctions and metabolic diseases. The second section is dedicated to the use of cyclodextrins in a range of biomedical technologies.

Abstract
Hepatitis C virus (HCV) infection always leads to chronic hepatitis via dysregulation of host immunity. Notch signaling also modulates the response of monocytes/macrophages. Thus, we aimed to investigate the regulatory role of Notch signaling to CD14+ monocytes. Forty patients with chronic hepatitis C and twenty normal controls (NC) were enrolled. CD14+ monocytes and CD4+ T cells were purified from peripheral bloods. Notch receptors' mRNA expression in CD14+ monocytes was semi-quantified by real-time PCR. Cytokine production by CD14+ monocytes in response to γ-secretase inhibitor (GSI) was investigated by ELISA. GSI-induced CD14+ monocytes activity to HCV clearance in Huh7.5 cells and to CD4+ T cell differentiation was also assessed in direct and indirect contact co-culture system. Notch1 mRNA relative level was approximately 10-fold elevated in CD14+ monocytes from chronic hepatitis C patients when compared with NC. GSI stimulation resulted in enhanced cytokines production by CD14+ monocytes from chronic hepatitis C patients. GSI-stimulated CD14+ monocytes from chronic hepatitis C patients induced suppression of HCV RNA replication in both direct and indirect contact co-culture system of CD14+ monocytes and HCVcc-infected Huh7.5 cells, and this process was accompanied by elevation of interferon-γ production but not increased target cell death. Moreover, GSI stimulation also enhanced CD14+ monocytes-induced Th1 and Th17 cells activation, and this process required direct cell-to-cell contact. Effective antiviral therapy down-regulated Notch1 mRNA expression and promoted cytokine production by CD14+ monocytes from chronic hepatitis C. Current data revealed an important immunoregulatory property of Notch signaling to CD14+ monocytes in chronic HCV infection.
