Abstract
Chronic liver disease is a major health issue worldwide and chronic hepatitis C (CHC) is associated with an increased risk of cirrhosis and hepatocellular carcinoma (HCC). There is evidence that the hepatitis C virus (HCV) infection is correlated with immune senescence by way of immune activation and chronic inflammation, which lead to increased metabolic and cardiovascular risk, as well as progressive liver damage. Both the innate and adaptive immunity are firmly tied to the prognosis of an infection with HCV and its response to antiviral therapy. HCV is therefore associated with increased pro-inflammatory status, heightened production of cytokines, prolonged systemic inflammation, as well as increased morbidity and mortality, mainly due to the progression of hepatic fibrosis and HCC, but also secondary to cardiovascular diseases. Viral hepatic pathology is increasingly considered a disease that is no longer merely limited to the liver, but one with multiple metabolic consequences. Numerous in vitro studies, using experimental models of acute or chronic inflammation of the liver, has brought new information on immunopathological mechanisms resulting from viral infections and have highlighted the importance of involving complex structures, inflammasomes complex, in these mechanisms, in addition to the involvement of numerous proinflammatory cytokines. Beyond obtaining a sustained viral response and halting the aforementioned hepatic fibrosis, the current therapeutic “treat-to-target” strategies are presently focused on immune-mediated and metabolic disorders, to improve the quality of life and long-term prognosis of CHC patients.

Abstract
Hepatitis C virus (HCV) infects 180 million people worldwide and over 4 million people in the United States. HCV infection is a major cause of chronic liver disease and is recognized as a risk factor for clinical cardiovascular disease (CVD). Many studies have shown increased prevalence of cardiac and inflammatory biomarkers in patients with chronic HCV infection (CHC), and though these markers may be used to risk stratify people for cardiac disease in the general population their role in the HCV population is unknown. Patients with CHC have elevated cardiac and inflammatory biomarkers compared to noninfected controls which may play a role in CVD risk stratification. We undertook a systematic review of inflammatory and cardiac biomarkers in people with HCV infection with a focus on the effect of CHC on serum levels of these markers and their utility as predictors of CVD in this population. Medline, EMBASE, and Cochrane databases were searched for relevant articles until June 2019. A total of 2430 results were reviewed with 115 studies included. Our review revealed that HCV infection significantly alters serum levels of markers of inflammation, endothelial function, and cardiac dysfunction prior to HCV treatment, and some of which may change in response to HCV therapy. Current risk stratification tools for development of CVD in the general population may not account for the increased inflammatory markers that appear to be elevated among HCV‐infected patients contributing to increased CVD risk.

Abstract
The present study evaluated the effects of heat-processed Scutellariae Radix (Scutellaria baicalensis) on lipopolysaccharide (LPS)-induced liver injury in mice. Scutellariae Radix heat-processed at 160[Formula: see text]C or 180[Formula: see text]C was orally administered at a dose of 100 mg/kg body weight for three days before the intraperitoneal injection of LPS, and the effects were compared with those of vehicle-treated LPS administered to control mice. The administration of Scutellariae Radix decreased the elevated serum monocyte chemotactic protein-1 (MCP-1), interleukin-6 (IL-6), reactive oxygen species (ROS), nitrite/nitrate, peroxynitrite, and hepatic functional parameters, and reduced the increased ROS in the liver. The augmented expressions of hepatic oxidative stress and inflammation-related proteins, phospho-p38, phosphorylated extracellular signal-regulated kinase, phosphorylated c-Jun N-terminal kinase, nuclear factor-[Formula: see text] B p65, activator protein-1, cyclooxygenase-2, inducible nitric oxide synthase, MCP-1, intercellular adhesion molecule-1, tumor necrosis factor-[Formula: see text], and IL-6, were downregulated by the heat-processed Scutellariae Radix. Hematoxylin-eosin staining showed that the increased hepatocellular damage in the liver of LPS-treated mice improved with the administration of heat-processed Scutellariae Radix. Overall, the ameliorative effects of Scutellariae Radix were superior to those when heat-processed at 180[Formula: see text]C. Our results indicate that heat-processed Scutellariae Radix acts as an anti-inflammatory agent by ameliorating oxidative stress in the liver of mice with LPS-induced liver injury.

Abstract
Hepatitis C is a liver disease caused by infection of the Hepatitis C virus (HCV). Many individuals infected by the virus are unable to resolve the viral infection and develop chronic hepatitis, which can lead to formation of liver cirrhosis and cancer. To understand better how initial HCV infections progress to chronic liver diseases, we characterised the long term pathogenic effects of HCV infections with the use of a humanised mouse model (HIL mice) we have previously established. Although HCV RNA could be detected in infected mice up to 9 weeks post infection, HCV infected mice developed increased incidences of liver fibrosis, granulomatous inflammation and tumour formation in the form of hepatocellular adenomas or hepatocellular carcinomas by 28 weeks post infection compared to uninfected mice. We also demonstrated that chronic liver inflammation in HCV infected mice was mediated by the human immune system, particularly by monocytes/macrophages and T cells which exhibited exhaustion phenotypes. In conclusion, HIL mice can recapitulate some of the clinical symptoms such as chronic inflammation, immune cell exhaustion and tumorigenesis seen in HCV patients. Our findings also suggest that persistence of HCV-associated liver disease appear to require initial infections of HCV and immune responses but not long term HCV viraemia.

Genetic Variation in the IL-6 and HLA-DQB1 Genes Is Associated with Spontaneous Clearance of Hepatitis C Virus Infection. J Immunol Res 2016; 2016:6530436.

Abstract
Background. Millions of people are infected with hepatitis C virus (HCV) worldwide and 30% spontaneously clear the infection. Reasons for HCV clearance without antiviral treatment are not well understood. Methods. Blood was collected for DNA analysis from patients with chronic HCV infection or evidence of spontaneous clearance. To overcome anticipated limitations of small sample size, primary analyses consisted of a candidate gene analysis of 12 preselected genes based on known association with host immunologic response to HCV infection. To further reduce the impact of multiple testing on power, a single likelihood ratio test was conducted for each gene using all associated SNPs assayed on the Illumina Quad 610/660W chip. Step-down permutation methods were used to adjust for multiple testing in all analyses. Results. Ninety-five and 62 patients with HCV chronic infection or spontaneous clearance, respectively, were included for analysis. HLA-DQB1 (p = 1.76⁎10(-5)) and IL-6 (p = 0.0007) genes were significantly associated with spontaneous HCV clearance. IL-28B was not significantly associated with spontaneous clearance (p = 0.17). Conclusion. Our whole-gene analytic strategy identified a previously unreported association of IL-6 with spontaneous clearance of HCV infection. We also confirmed the finding that HLA-DQB1 is associated with spontaneous resolution of HCV infection.

Abstract
Monocyte chemoattractant protein-1 (MCP-1) is a cytokine that mediates the influx of cells to sites of inflammation. Our group recently reported that propofol exerted an anti-inflammatory effect and could inhibit lipopolysaccharide (LPS)-induced production of pro-inflammatory cytokines. However, the effect and possible mechanisms of propofol on MCP-1 expression remain unclear. LPS-stimulated HepG2 cells were treated with 50 μM propofol for 0, 6, 12, and 24 h, respectively. The transcript and protein levels were measured by real-time quantitative PCR and Western blot analyses, respectively. We found that propofol markedly decreased both MCP-1 messenger RNA (mRNA) and protein levels in LPS-stimulated HepG2 cells in a time-dependent manner. Expression of apolipoprotein M (apoM) and forkhead box protein A2 (foxa2) was increased by propofol treatment in HepG2 cells. In addition, the inhibitory effect of propofol on MCP-1 expression was significantly abolished by small interfering RNA against apoM and foxa2 in LPS-stimulated HepG2 cells. Propofol attenuates LPS-induced MCP-1 production through enhancing apoM and foxa2 expression in HepG2 cells.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease that is characterized by the production of autoantibodies against nuclear antigens such as double-stranded DNA. Lupus predominantly affects women (ratio, 9:1). Moreover, premenopausal women with SLE are 50 times more likely to have a myocardial infarction. Although specific risk factors for advanced cardiovascular complications have not been identified in this patient population, endothelial dysfunction is highly prevalent. Recent studies show that the type I interferon signature gene expression coincides with impaired brachial artery flow-mediated dilation and diminished endothelial progenitor cell circulation, both markers of impaired endothelial function. Although many factors promote the development of vascular endothelial dysfunction, all pathways converge on the diminished activity of endothelial nitric oxide synthase (eNOS) and loss of nitric oxide (NO) bioavailability. Studies examining the effects of type I interferons on eNOS and NO in SLE are missing. This literature review examines the current literature regarding the role of type I interferons in cardiovascular disease and its known effects on regulators of eNOS and NO bioavailability that are important for proper endothelial cell function.

Abstract
7-O-Galloyl-D-sedoheptulose (GS) is the bioactive polyphenol isolated from the low-molecular-weight fraction of Corni Fructus (Cornus officinalis Sieb. et Zucc.). The present study was conducted to examine whether GS has an ameliorative effect on the liver of type 2 diabetic db/db mice. GS (20 or 100 mg/kg body weight/day, per os) was administered every day for 6 weeks to db/db mice, and its effect was compared with vehicle-treated db/db and m/m mice. The administration of GS decreased the elevated serum glucose, leptin, insulin, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), resistin, and hepatic functional parameters, and reduced the increased fluorescent advanced glycation endproducts (AGEs) and reactive oxygen species in the liver. The db/db mice exhibited the up-regulation of receptor for AGEs (RAGE) and AGE-related proteins; however, GS treatment significantly reduced those expressions. Moreover, the augmented expressions of oxidative stress- and inflammation-related proteins, phospho-extracellular-signal regulated kinase 1/2, phospho-c-Jun N-terminal kinase, nuclear factor-kappa B, activator protein-1, monocyte chemotactic protein-1, intracellular adhesion molecule-1, TNF-α, and IL-6, were down-regulated by GS administration. Hematoxylin-eosin staining showed that the increased hepatocellular damage in the liver of db/db mice improved with GS administration. The present results support the evidence for GS ameliorating hepatic damage through the RAGE-mediated inflammation pathway.

Abstract
BACKGROUND Immune biomarkers are implicated in HCV treatment response, fibrosis, and accelerated pathogenesis of comorbidities, though only D-dimer and C-reactive protein have been consistently studied. Few studies have evaluated HIV/HCV co-infection, and little longitudinal data exists describing a broader antiviral cytokine response. METHODS Fifty immune biomarkers were analyzed at baseline (BL) and HCV end of treatment follow-up(FU) time point using the Luminex 50-plex assay in plasma samples from 15 HCV-cleared, 24 HCV mono- and 49 HIV/HCV co-infected patients receiving antiretroviral treatment, who either did or did not receive pegylated-interferon/ribavirin HCV treatment. Biomarker levels were compared among spontaneous clearance patients, mono- and co-infected, untreated and HCV-treated, and sustained virologic responders (SVR) and non-responders (NR) at BL and FU using nonparametric analyses. A Bonferroni correction, adjusting for tests of 50 biomarkers, was used to reduce Type I error. RESULTS Compared to HCV patients at BL, HIV/HCV patients had 22 significantly higher and 4 significantly lower biomarker levels, following correction for multiple testing. There were no significantly different BL levels when comparing SVR and NR in mono- or co-infected patients; however, FU levels changed considerably in co-infected patients, with seven becoming significantly higher and eight becoming significantly lower in SVR patients. Longitudinally between BL and FU, 13 markers significantly changed in co-infected SVR patients, while none significantly changed in co-infected NR patients. There were also no significant changes in longitudinal analyses of mono-infected patients achieving SVR or mono-infected and co-infected groups deferring treatment. CONCLUSIONS Clear differences exist in pattern and quantity of plasma immune biomarkers among HCV mono-infected, HIV/HCV co-infected, and HCV-cleared patients; and with SVR in co-infected patients treated for HCV. Though >90% of patients were male and co-infected had a larger percentage of African American patients, our findings may have implications for better understanding HCV pathogenesis, treatment outcomes, and future therapeutic targets.

Abstract
BACKGROUND The relationship between cytokines and responses to peginterferon alpha-2a treatment in chronic hepatitis B patients has not yet been fully elucidated. We analyzed the serum levels of interleukin (IL)-1alpha, IL-1beta, IL-2, IL-4, IL-6, IL-8, IL-10, vascular endothelial growth factor, interferon-gamma, tumor necrosis factor-alpha, monocyte chemotactic protein-1 (MCP1) and epidermal growth factor during the treatment with peginterferon alpha-2a. METHODS Ninety-three serum samples from 20 chronic hepatitis B patients were collected before, during and after 48 weeks of peginterferon therapy and were assayed for 12 cytokines. The patients were categorized as either virologic responders (VRs) or non-responders (NRs) according to their HBV DNA levels taken at 6th month during treatment. The Evidence Investigator (Randox, Antrim, UK), a protein chip analyzer, was used to quantify cytokines. RESULTS Among the 12 cytokines, the levels of MCP1 were increased and the levels of IL-4 were decreased during the treatment in VRs. However these cytokines were not significantly changed in NRs in the treatment phases. Area under the receiver operating characteristic curve (AUROC) value of HBV DNA measured before the treatment was 0.81 in predicting VRs, and that of the baseline MCP1 was 0.76. IL-6 levels at 3rd and 6th months during the treatment also showed AUROC values 0.85 and 0.78 respectively in predicting sustained VRs. CONCLUSION Serum cytokine levels reflect the pathological differences of individual treatment phases and could also be useful in monitoring responses to peginterferon treatment in chronic hepatitis B patients.

Abstract
Chronic inflammation contributes to many prevalent diseases worldwide, and it is widely accepted that inflammatory molecules contribute to DNA damage. In this ancillary study, we investigated the influence of an encapsulated fruit and vegetable juice powder concentrate on peripheral blood lymphocytes (PBL) DNA damage. Using a double-blind, placebo-controlled approach, subjects were randomly assigned capsules containing placebo, or one of two formulations of the juice powder. Blood was drawn at baseline and after 60 days of capsule consumption. We found DNA damage in isolated PBL is suppressed after consumption of the encapsulated juice powder, and damage was correlated with the level of systemic inflammation. These data suggest a potential health benefit by consuming the juice concentrate capsules through their ability to suppress DNA damage as measured in surrogate tissues (PBL).

Abstract
To evaluate CXCL10 and CCL2 in patients with hepatitis C virus chronic infection in presence/absence of autoimmune thyroiditis (AT). CXCL10 was significantly higher in: (1) patients with AT than controls without AT (control 1) (P < 0.001; ANOVA); (2) patients with hepatitis C infection than control 1 and patients with AT (P < 0.001); (3) patients with hepatitis C virus chronic infection and AT (HCV+AT) than control 1 and patients with AT (P < 0.001) and hepatitis C (P = 0.004). By defining a high CXCL10 level as a value >218 pg/mL, 2% of control 1, 14% of patients with AT, 68% of patients with hepatitis C infection, 81% of HCV+AT had high CXCL10 (P < 0.0001; chi-square). CCL2 was similar in control 1 and patients with AT. CCL2 was significantly higher in: (1) patients with hepatitis C infection than control 1 (P = 0.04; ANOVA); (2) HCV+AT than patients with AT (P = 0.03) and control 1 (P = 0.02); no difference was observed between HCV with or without AT. Our study demonstrates: (1) higher circulating CXCL10 and CCL2 in patients with hepatitis C virus chronic infection than in controls; (2) higher CXCL10 in HCV+AT than in patients with hepatitis C infection, suggesting a stronger Th1 immune response in these patients.

Abstract
BACKGROUND No study evaluates serum levels of CXCL10 and CCL2 chemokines in patients with hepatitis C associated mixed cryoglobulinaemia. AIMS To measure circulating CXCL10 and CCL2 in cryoglobulinaemic patients. PATIENTS AND METHODS Serum CXCL10 and CCL2 were assayed in 70 consecutive cryoglobulinaemic patients, and in 2 control groups (1:1, gender- and age-matched) of healthy (controls), or of chronic hepatitis C subjects without cryoglobulinaemia. RESULTS Cryoglobulinaemic patients showed higher CXCL10 serum levels than controls (p<0.0001), or hepatitis C patients (p=0.001) (389 +/- 141, 91 +/- 51, 311 +/- 142 pg/ml, respectively). By defining a "high CXCL10" as a value at least 2 S.D. above the mean value of the control group (>193 pg/ml), 79% of cryoglobulinaemic patients, 5% of the controls and 69% of hepatitis C patients had high CXCL10 (p<0.0001). CXCL10 levels were (p<0.01) increased in cryoglobulinaemic patients with active vasculitis, with respect to those without (445+/-108, 339 +/- 161 pg/ml, respectively). Cryoglobulinaemic patients showed significantly higher CCL2 serum level than controls (p<0.01), but not than hepatitis C patients (541 +/- 493, 387 +/- 173 and 451 +/- 281 pg/ml, respectively). CONCLUSION Our study first demonstrates high serum levels of CXCL10 and CCL2 chemokines in cryoglobulinaemic patients. Circulating CXCL10 is higher overall in cryoglobulinaemic patients with active vasculitis, suggesting a prevalence of the Th1 immune response in this phase.

Abstract
Chemokines have been identified to play an important role in endocrine autoimmune disease and hepatitis C chronic infection. To our knowledge, no study has evaluated serum levels of CXCL10 and CCL2 in patients with "mixed cryoglobulinemia and hepatitis C virus chronic infection" (MC) in the presence or absence of autoimmune thyroiditis (AT). Serum CXCL10 and CCL2 were assayed in 60 patients with MC, in 45 patients with "MC with AT" (MC + AT), and in controls (60 without [control 1] and 45 with AT [control 2]). CXCL10 was significantly higher (1) in control 2 than in control 1 (P < .001), (2) in MC than in control 1, and (3) in MC + AT than in controls 1 and 2 and in MC (P = .002). A high CXCL10 level (>mean + SD control 1; >167 pg/mL) was present in 7% control 1, 21% control 2, 49% MC, and 78% MC + AT (P < .0001). CCL2 was significantly higher in MC and in MC + AT than in control 1 or in control 2 (P < .01). A high CCL2 level (>mean + SD control 1; >730 pg/mL) was present in 2% control 1, 1% control 2, 18% MC, and 21% MC + AT (P < .0001). The study demonstrates high CXCL10 and CCL2 serum levels in patients with MC; CXCL10 in MC + AT is significantly higher than that in MC. Future studies in larger series will be needed to evaluate the potential usefulness of serum CXCL10 and CCL2 determination as a prognostic marker in the follow-up of MC patients, also in relation to the presence of AT.

Abstract
The present investigation was designed to identify potential biomarker(s) and assess the involvement of inflammatory pathway in dimethylnitrosamine (DMN)-induced liver fibrosis in rats. Following DMN-treatment (10 mg/ml/kg, i.p., given three consecutive days each week for 4 weeks) body and liver weights were significantly decreased concurrent with increasing severity of liver damage assessed by bridging fibrosis, a histopathologic assessment and characteristic of human liver disease. Protein C along with albumin, C-reactive-protein (CRP), haptoglobin and total protein were significantly reduced and correlated with changes in liver histopathology. Biochemical markers of liver functions were significantly increased and correlated with changes in liver histopathology and plasma levels of protein C. Soluble intracellular-adhesion-molecule-1 (sICAM-1) levels were increased significantly but were poorly correlated with histopathology and protein C levels. Inflammatory chemokines and other analytes, monocyte-chemoattractant-protein-1 and 3 (MCP-1 and MCP-3), macrophage-colony-stimulating-factor (M-CSF) were significantly increased during the disease progression, whereas macrophage-derived-chemokine (MDC) and CRP were significantly suppressed. Circulating neutrophils and monocytes were also increased along with disease progression. The differential changes in sICAM-1, hyaluronic acid, gamma-glutamyltranspeptidase (GGT), neutrophil and other inflammatory chemokines suggest the involvement of inflammatory pathways in DMN-induced liver fibrosis. In conclusion, the progressive changes in protein C along with other noninvasive biochemical parameters whose levels were significantly correlated with disease progression may serve as biomarkers for pharmacological assessment of targeted therapy for liver fibrosis.

Abstract
BACKGROUND Hereditary Hemochromatosis (HH) is a genetic disease associated with iron overload, in which individuals homozygous for the mutant C282Y HFE associated allele are at risk for the development of a range of disorders particularly liver disease. Conformational diseases are a class of disorders associated with the expression of misfolded protein. HFE C282Y is a mutant protein that does not fold correctly and consequently is retained in the Endoplasmic Reticulum (ER). In this context, we sought to identify ER stress signals associated with mutant C282Y HFE protein expression, which may have a role in the molecular pathogenesis of HH. RESULTS Vector constructs of Wild type HFE and Mutant C282Y HFE were made and transfected into HEK293 cell lines. We have shown that expression of C282Y HFE protein triggers both an unfolded protein response (UPR), as revealed by the increased GRP78, ATF6 and CHOP expression, and an ER overload response (EOR), as indicated by NF-kappaB activation. Furthermore, C282Y HFE protein induced apoptotic responses associated with activation of ER stress. Inhibition studies demonstrated that tauroursodeoxycholic acid, an endogenous bile acid, downregulates these events. Finally, we found that the co-existence of both C282Y HFE and Z alpha 1-antitrypsin protein (the protein associated with the liver disease of Z alpha 1-antitrypsin deficiency) expression on ER stress responses acted as potential disease modifiers with respect to each other. CONCLUSION Our novel observations suggest that both the ER overload response (EOR) and the unfolded protein response (UPR) are activated by mutant C282Y HFE protein.

Abstract
This study was to evaluate the effects of thalidomide on expression of adhesion molecules in liver cirrhosis. The cirrhosis was induced in Wistar rats by intraperitoneal injection of CCl(4), and thalidomide (10 mg/kg/day or 100 mg/kg/day) was given by intragastric administration for 8 weeks. Liver histopathology and immunohistochemistry were significantly improved and the expressions of ICAM-1, VCAM-1, E-selectin, and TNF-alpha mRNA and protein were decreased significantly in rats treated with a high dose of thalidomide. Close positive correlation was observed in the expression of the TNF-alpha mRNA and that of ICAM-1, VCAM-1, and E-selectin mRNA, respectively. These results indicate that thalidomide exerts its effect on the downregulation of adhesion molecules via TNF-alpha signaling pathway to inhibit liver fibrosis.

Abstract
We investigated the relationships between plasma monocyte chemoattractant protein-1, serum C-reactive protein, and the degree of hepatic inflammation in patients with chronic liver disease. Monocyte chemoattractant protein-1 concentration was correlated with the histological hepatic inflammation (estimated by the Knodell index) and with standard liver function tests (P<0.01). C-reactive protein was not correlated with any of the variables studied. These results underline the role of monocyte chemoattractant protein-1 in the pathogenesis of liver impairment and suggest that this chemokine may be a reliable marker of inflammation in hepatic derangements.
