Abstract
Established evidence indicates that oral microbiota plays a crucial role in modulating host immune responses to viral infection. Following severe acute respiratory syndrome coronavirus 2, there are coordinated microbiome and inflammatory responses within the mucosal and systemic compartments that are unknown. The specific roles the oral microbiota and inflammatory cytokines play in the pathogenesis of coronavirus disease 2019 (COVID-19) are yet to be explored. Here, we evaluated the relationships between the salivary microbiome and host parameters in different groups of COVID-19 severity based on their oxygen requirement. Saliva and blood samples (n = 80) were collected from COVID-19 and from noninfected individuals. We characterized the oral microbiomes using 16S ribosomal RNA gene sequencing and evaluated saliva and serum cytokines and chemokines using multiplex analysis. Alpha diversity of the salivary microbial community was negatively associated with COVID-19 severity, while diversity increased with health. Integrated cytokine evaluations of saliva and serum showed that the oral host response was distinct from the systemic response. The hierarchical classification of COVID-19 status and respiratory severity using multiple modalities separately (i.e. microbiome, salivary cytokines, and systemic cytokines) and simultaneously (i.e. multimodal perturbation analyses) revealed that the microbiome perturbation analysis was the most informative for predicting COVID-19 status and severity, followed by the multimodal. Our findings suggest that oral microbiome and salivary cytokines may be predictive of COVID-19 status and severity, whereas atypical local mucosal immune suppression and systemic hyperinflammation provide new cues to understand the pathogenesis in immunologically compromised populations.

Abstract
The serum chemokine C-X-C motif ligand-10 (CXCL10) and its unique receptor (CXCR3) may predict the prognosis of patients with chronic hepatitis B (CHB) treated with tenofovir disoproxil fumarate (TDF). Nevertheless, there are few reports on the profile of CXCL10 and CXCR3 and their clinical application in HBeAg (+) CHB patients during TDF antiviral therapy. CXCL10 and CXCR3 were determined in 118 CHB patients naively treated with TDF for at least 96 weeks at baseline and at treatment weeks 12 and 24. In addition, gene set enrichment analysis was used to examine the associated dataset from Gene Expression Omnibus and explore the gene sets associated with HBeAg seroconversion (SC). The change of CXCL10 (ΔCXCL10, baseline to 48-week TDF treatment) and CXCR3 (ΔCXCR3) is closely related to the possibility of HBeAg SC of CHB patients under TDF treatment. Immunohistochemical analysis of CXCL10/CXCR3 protein in liver tissue shows that there is a significant difference between paired liver biopsy samples taken before and after 96 weeks of successful TDF treatment of CHB patients (11 pairs) but no significance for unsuccessful TDF treatment (14 pairs). Multivariate Cox analysis suggests that the ΔCXCL10 is an independent predictive indicator of HBeAg SC, and the area under the receiver operating characteristic curve of the ΔCXCL10 in CHB patients is 0.8867 (p < 0.0001). Our results suggest that a lower descending CXCL10 level is associated with an increased probability of HBeAg SC of CHB patients during TDF therapy. Moreover, liver tissue CXCL10 might be involved in the immunological process of HBeAg SC.

Abstract
INTRODUCTION Atezolizumab plus bevacizumab combination therapy (AB) was the first-line treatment for unresectable hepatocellular carcinoma (u-HCC). IFN-γ-induced protein 10 (IP-10/CXCL10) is a chemokine to inhibit HCC proliferation by promoting the migration of cytotoxic T cells. We focused on the relationship between plasma IP-10/CXCL10 levels and the initial therapeutic response in patients receiving AB therapy. METHODS Forty-six patients receiving AB therapy were enrolled. Plasma IP-10/CXCL10 levels were measured at baseline, 3-7 days, 3 weeks, 6 weeks, and 8-12 weeks after the start of AB therapy. The initial therapeutic response was evaluated at 8-12 weeks. RESULTS The baseline IP-10/CXCL10 levels of partial response (PR) group was higher than that of stable disease (SD) or progressive disease (PD) group. Patients with the baseline IP-10/CXCL10 of 84 pg/mL or higher were likely to present PR than patients below (71 vs. 35%, p = 0.031), but prediction of PD using the baseline IP-10/CXCL10 levels was difficult. In contrast, IP-10/CXCL10 ratio of the PR group was lower than that of the SD/PD group at 3, 6, and 8-12 weeks. Patients with the 3, 6, and 8-12 weeks IP-10/CXCL10 ratio of 1.3, 0.4, and 0.4 or lower were likely to present PR than patients with ≥1.3, 0.4, and 0.4 (88, 35, 35 vs. 30, 3.8, 0%, p < 0.001, 0.011, 0.002). In other hand, the 3, 6, and 8-12 weeks IP-10/CXCL10 ratio for PD group was higher than that for non-PD group. Patients with the 3, 6, and 8-12 weeks IP-10/CXCL10 ratio of 1.3, 1.7, and 1.9 or higher were likely to present PD than patients below (85, 62, 57 vs. 32, 23, 14%, p = 0.002, 0.034, 0.009). CONCLUSION High baseline IP-10/CXCL10 levels may be associated with better outcome, and high IP-10/CXCL10 ratio after 3-12 weeks may be associated with worse outcome in u-HCC patients receiving AB therapy.

Serum cytokine change profile associated with HBsAg loss during combination therapy with PEG-IFN-α in NAs-suppressed chronic hepatitis B patients. Front Immunol 2023; 14:1121778. [PMID: 36756119 PMCID: PMC9899895 DOI: 10.3389/fimmu.2023.1121778] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Accepted: 01/09/2023] [Indexed: 01/24/2023] Open
Abstract
Objective The aim of this study was to explore the profile of cytokine changes during the combination therapy with pegylated interferon alpha (PEG-IFN-α) and its relationship with HBsAg loss in nucleos(t)ide analogs (NAs)-suppressed chronic hepatitis B patients. Methods Seventy-six patients with chronic hepatitis B with HBsAg less than 1,500 IU/ml and HBV DNA negative after receiving ≥ 1-year NAs therapy were enrolled. Eighteen patients continued to take NAs monotherapy (the NAs group), and 58 patients received combination therapy with NAs and PEG-IFN-α (the Add-on group). The levels of IFNG, IL1B, IL1RN, IL2, IL4, IL6, IL10, IL12A, IL17A, CCL2, CCL3, CCL5, CXCL8, CXCL10, TNF, and CSF2 in peripheral blood during treatment were detected. Results At week 48, 0.00% (0/18) in the NAs group and 25.86% (15/58) in the Add-on group achieved HBsAg loss. During 48 weeks of combined treatment, there was a transitory increase in the levels of ALT, IL1RN, IL2, and CCL2. Compared to the NAs group, CXCL8 and CXCL10 in the Add-on group remain higher after rising, yet CCL3 showed a continuously increasing trend. Mild and early increases in IL1B, CCL3, IL17A, IL2, IL4, IL6, and CXCL8 were associated with HBsAg loss or decrease >1 log, while sustained high levels of CCL5 and CXCL10 were associated with poor responses to Add-on therapy at week 48. Conclusions The serum cytokine change profile is closely related to the response to the combination therapy with PEG-IFN-α and NAs, and may help to reveal the mechanism of functional cure and discover new immunological predictors and new therapeutic targets.

Abstract
Background & Aims We aim to describe the liver immune microenvironment by analyzing liver biopsies from patients with chronic HBV infection (CHB). Host immune cell signatures and their corresponding localization were characterized by analyzing the intrahepatic transcriptome in combination with a custom multiplex immunofluorescence panel. Method Matching FFPE and fresh frozen liver biopsies were collected from immune active patients within the open-label phase IV study GS-US-174-0149. RNA-Seq was conducted on 53 CHB liver biopsies from 46 patients. Twenty-eight of the 53 samples had matched FFPE biopsies and were stained with a 12-plex panel including cell segmentation, immune and viral biomarkers. Corresponding serum samples were screened using the MSD Human V-plex Screen Service to identify peripheral correlates for the immune microenvironment. Results Using unsupervised clustering of the transcriptome, we reveal two unique liver immune signatures classified as immune high and immune low based on the quantification of the liver infiltrate gene signatures. Multiplex immunofluorescence analysis demonstrated large periportal lymphoid aggregates in immune high samples consisting of CD4 and CD8 T cells, B cells and macrophages. Differentiation of the high and low immune microenvironments was independent of HBeAg status and peripheral viral antigen levels. In addition, longitudinal analysis indicates that treatment and normalization of ALT correlates with a decrease in liver immune infiltrate and inflammation. Finally, we screened a panel of peripheral biomarkers and identified ICAM-1 and CXCL10 as biomarkers that strongly correlate with these unique immune microenvironments. Conclusion These data provide a description of immune phenotypes in patients with CHB and show that immune responses are downregulated in the liver following nucleotide analogue treatment. This may have important implications for both the safety and efficacy of immune modulator programs aimed at HBV cure. Lay summary Liver biopsies from patients with chronic hepatitis B were submitted to RNA-Seq and multiplex immunofluorescence and identified two different liver immune microenvironments: immune high and immune low. Immune high patients showed elevated immune pathways, including interferon signaling pathways, and increase presence of immune cells. Longitudinal analysis of biopsies from treatment experienced patients showed that treatment correlates with a marked decrease in inflammation and these findings may have important implications for both safety and efficacy of immune modulator programs for HBV cure.

Peg-interferon alpha add-on Tenofovir disoproxil fumarate achieved more HBsAg loss in HBeAg-positive chronic hepatitis B naïve patients. J Viral Hepat 2021; 28:1381-1391.

Abstract
Several studies have showed that combining peg-interferon alpha (Peg-IFNα) with nucleotide analogues has complementary effects in chronic hepatitis B (CHB), but the optimal regimen and potential mechanisms remain unclear. This was a prospective, longitudinal and multicentre clinical trial (NCT03013556). HBeAg-positive CHB naïve patients were randomly assigned to three groups: tenofovir disoproxil fumarate (TDF) monotherapy for 96 weeks, TDF alone for 48 weeks and sequentially Peg-IFNα added for 48 weeks, TDF de novo combination with Peg-IFNα for 48 weeks then TDF alone for 48 weeks. The primary endpoint was HBeAg seroconversion at week 96 and HBsAg loss as the secondary endpoint. Furthermore, the levels of 12 cytokines in serum were assessed at different time points. A total of 133 patients were included in the analysis. The rates of HBeAg seroconversion at 96 weeks were not significant different among the three groups (p = 0.157). Interestingly, patients in the Peg-IFNα add-on group showed markedly lower HBsAg level compared with the other two groups at week 96. In addition, only three patients in the Peg-IFNα add-on group achieved HBsAg loss. For the following 24 weeks from week 96, no HBsAg reappearance in the three patients and no new patients with HBsAg loss were observed in the three groups. Serum cytokine analysis showed that the baseline level of interferon-inducible protein-10 (IP-10) was strongly higher in HBeAg conversion patients and HBsAg loss patients. Compared with de novo combination and TDF alone, the addition of Peg-IFNα in TDF-treated group might be an effective strategy for HBsAg loss in HBeAg-positive CHB naïve patients.

Abstract
Chemokines are crucial inflammatory mediators needed during an immune response to clear pathogens. However, their excessive release is the main cause of hyperinflammation. In the recent COVID-19 outbreak, chemokines may be the direct cause of acute respiratory disease syndrome, a major complication leading to death in about 40% of severe cases. Several clinical investigations revealed that chemokines are directly involved in the different stages of SARS-CoV-2 infection. Here, we review the role of chemokines and their receptors in COVID-19 pathogenesis to better understand the disease immunopathology which may aid in developing possible therapeutic targets for the infection.

The association between serum cytokine and chemokine levels and antiviral response by entecavir treatment in chronic hepatitis B patients. Antivir Ther 2019; 23:239-248.

Abstract
BACKGROUND Although nucleoside/nucleotide analogue therapy is thought to suppress chronic hepatitis B (CHB) via regulation of inflammatory cytokines/chemokines, the mechanism is still unclear. In this study, serum cytokine/chemokine levels were measured in CHB patients treated with entecavir, and the association with antiviral response was analysed. METHODS A total of 78 Japanese patients with CHB were enrolled, and serum cytokine/chemokine levels were measured at baseline and at 12, 24 and 48 weeks of entecavir treatment using the MULTIPLEX kit. RESULTS Antiviral response to entecavir treatment was significantly associated with hepatitis B surface antigen (HBsAg) titre and serum interferon-gamma-inducible protein 10 (IP-10) level (12w; P=0.0002; OR=0.020 [95% CI 0.002, 0.156], P=0.003; OR=0.042 [95% CI 0.005, 0.336], respectively). HBe-positive patients whose serum macrophage-derived chemokine (MDC) level was lower (<582.83 pg/ml) and IP-10 level was higher (≥1,323.13 pg/ml) achieved hepatitis B e antigen (HBeAg) loss earlier than those who remained HBeAg-positive (P=0.044). HBsAg reduction by entecavir treatment was significantly associated with higher initial tumour necrosis factor-alpha (TNF-α) level (≥15.20 pg/ml) and higher alanine aminotransferase level (≥73 IU/l; P=0.009; OR=18.460 [95% CI 2.044, 166.709], P=0.022; OR=7.709 [95% CI 1.341, 44.327], respectively). CONCLUSIONS Results of the present study indicate that changes in cytokine/chemokine levels following entecavir therapy are associated with response to antiviral therapy in CHB patients. Monitoring of serum cytokine/chemokine levels could be useful for predicting reduction of HBV DNA and HBsAg and HBe seroconversion.

Circulating CXCL10 in cirrhotic portal hypertension might reflect systemic inflammation and predict ACLF and mortality. Liver Int 2018; 38:875-884.

Abstract
BACKGROUND & AIMS CXCR% ligands play an important role in hepatic injury, inflammation and fibrosis. While CXCL9 and CXCL11 are associated with survival in patients receiving transjugular intrahepatic portosystemic shunt (TIPS), the role of CXCL10 in severe portal hypertension remains unknown. METHODS A total of 89 cirrhotic patients were analysed. CXCL10 protein levels were measured in portal and hepatic blood at TIPS insertion and 2 weeks later in 24 patients. CXCL10 and IL8 levels were assessed in portal, hepatic, cubital vein and right atrium blood in a further 25 patients at TIPS insertion. Furthermore, real-time PCR determined hepatic CXCL10-mRNA in 40 cirrhotic patients. RESULTS Hepatic CXCL10 showed no association with decompensation. By contrast, circulating CXCL10-levels were higher in portal than in hepatic vein blood, suggesting an extrahepatic source of CXCL10 in cirrhosis. However, CXCL10 protein in blood samples from portal, hepatic, cubital veins and right atrium correlated excellently with each other and with IL-8 levels. Higher CXCL10 circulating levels were associated with presence of ascites and higher Child scores. Higher CXCL10 circulating protein levels were associated with acute decompensation, acute-on-chronic liver failure (ACLF) and independently with mortality. Moreover, a decrease in CXCL10 protein levels after TIPS insertion was associated with better survival in each cohort and analysed together. DISCUSSION Circulating CXCL10 possibly reflects systemic inflammation and it is correlated with acute decompensation, ACLF and complications in patients with severe portal hypertension receiving TIPS. CXCL10 predicts survival in these patients and a decrease in CXCL10 after TIPS may be considered a good prognostic factor.

Association of mRNA expression level of IP-10 in peripheral blood mononuclear cells with HBV-associated acute-on-chronic liver failure and its prognosis. Curr Med Sci 2017; 37:755-760.

Abstract
HBV-associated acute-on-chronic liver failure is prevalent in mainland China. The prognosis of HBV-ACLF is poor. The mortality of HBV-ACLF is approximately 80%. Therefore, a prognostic indicator was needed in order to allow us to intervene as soon as possible. The model for end-stage liver disease (MELD) scoring system is widely used to predict the prognosis of liver failure. However, the assessment is too complex to restrict its application. This study aimed to investigate the expression of IP-10 in peripheral blood mononuclear cells (PBMC), in order to explore the relationship between the expression and prognosis of patients with HBV-ACLF. The mRNA level of IP-10 in PBMCs were analyzed in 80 patients with HBV-ACLF, 40 patients with chronic hepatitis B (CHB) and 40 healthy people by fluorescent quantitative PCR. IP-10 mRNA level was significantly higher in the HBV-ACLF group than in the other two groups (P<0.01). Group with MELD score below 30 had lower IP-10 mRNA level than group with MELD score over 30 (P<0.05). The IP-10 mRNA level in PBMCs in positive group was higher than that in negative group (P<0.01). With a threshold of 0.925, the area under the receiver operating characteristic (ROC) curves was 0.815. These findings suggest that assessment of IP-10 mRNA level in the PBMCs would be helpful for evaluating the disease severity and prognosis in patients with HBV-ACLF.

Abstract
Chemokines are small chemotactic cytokines that are involved in the regulation of immune cell migration. Multiple functional properties of chemokines, such as pro-inflammation, immune regulation, and promotion of cell growth, angiogenesis, and apoptosis, have been identified in many pathological and physiological contexts. Human immunodeficiency virus (HIV) infection is characterized by persistent inflammation and immune activation during both acute and chronic phases, and the "cytokine storm" is one of the hallmarks of HIV infection. Along with immune activation after HIV infection, an extensive range of chemokines and other cytokines are elevated, thereby generating the so-called "cytokine storm." In this review, the effects of the upregulated chemokines and chemokine receptors on the processes of HIV infection are discussed. The objective of this review was to focus on the main chemokines and chemokine receptors that have been found to be associated with HIV infection and latency. Elevated chemokines and chemokine receptors have been shown to play important roles in the HIV life cycle, disease progression, and HIV reservoir establishment. Thus, targeting these chemokines and receptors and the other proteins of related signaling pathways might provide novel therapeutic strategies, and the evidence indicates a promising future regarding the development of a functional cure for HIV.

Abstract
Interferon-γ-inducible protein 10 (IP-10), also known as chemokine C-X-C motif ligand (CXCL) 10, is closely associated with antiviral immunity and the progression of chronic hepatitis B (CHB). However, the value of baseline serological and histological IP-10 expression levels in predicting the efficacy of the antiviral response to nucleoside/nucleotide analogues (NAs) is still unknown. In our research, intrahepatic and peripheral IP-10 expression levels were systemically examined before and after treatment with entecavir (ETV). Baseline serological and histological IP-10 expression levels were significantly increased in patients with CHB, particularly in patients with higher degrees of liver inflammation and liver fibrosis. Moreover, higher baseline intrahepatic IP-10 levels indicated better prognoses in patients with CHB after entecavir therapy. The baseline IP-10 level was also positively associated with several clinical parameters, including baseline levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hepatitis B virus (HBV) DNA, and hepatitis B surface antigen (HBsAg), and with the decrease in HBsAg levels after treatment. In addition, monocyte-derived IP-10 was expressed at higher levels in patients with CHB than in patients with liver cirrhosis (LC) and healthy controls (HC). According to the results of our in vitro experiments, IP-10 directly promoted hepatocyte apoptosis. Based on these findings, baseline serological and histological IP-10 levels might predict CHB severity and the decrease in HBsAg levels after entecavir therapy.

Abstract
Challenges in the management of chronic hepatitis B virus (HBV) infection involve the prediction of the natural course to identify patients who require antiviral therapy and the prediction of functional cure as ultimate goal of antiviral therapy. HBV DNA as marker for viral replication is important but not sufficient for an adequate management of patients with chronic HBV infection. Data on the quantification of additional HBV marker such as hepatitis B surface antigen (HBsAg), hepatitis B core-related antigen (HBcrAg) and hepatitis B virus RNA (HBV RNA) have accumulated in recent years. Here we review the current evidence how to use these markers and discuss open issues that require additional research.
