Abstract
Liver fibrosis accompanies the development of various chronic liver diseases and promotes their progression. It is characterized by the abnormal accumulation of extracellular matrix proteins (ECM) and impaired ECM degradation. Activated hepatic stellate cells (HSCs) are the major cellular source of ECM-producing myofibroblasts. If liver fibrosis is uncontrolled, it may lead to cirrhosis and even liver cancer, primarily hepatocellular carcinoma (HCC). Natural killer (NK) cells are a key component of innate immunity and have miscellaneous roles in liver health and disease. Accumulating evidence shows that NK cells play dual roles in the development and progression of liver fibrosis, including profibrotic and anti-fibrotic functions. Regulating NK cells can suppress the activation of HSCs and improve their cytotoxicity against activated HSCs or myofibroblasts to reverse liver fibrosis. Cells such as regulatory T cells (Tregs) and molecules such as prostaglandin E receptor 3 (EP3) can regulate the cytotoxic function of NK cells. In addition, treatments such as alcohol dehydrogenase 3 (ADH3) inhibitors, microRNAs, natural killer group 2, member D (NKG2D) activators, and natural products can enhance NK cell function to inhibit liver fibrosis. In this review, we summarized the cellular and molecular factors that affect the interaction of NK cells with HSCs, as well as the treatments that regulate NK cell function against liver fibrosis. Despite a lot of information about NK cells and their interaction with HSCs, our current knowledge is still insufficient to explain the complex crosstalk between these cells and hepatocytes, liver sinusoidal endothelial cells, Kupffer cells, B cells, and T cells, as well as thrombocytes, regarding the development and progression of liver fibrosis.

Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) remains a major clinical problem as more than half of these cases recur after radical resection. Natural killer (NK) cells are at the forefront of the innate immune system and attack microcarcinomas and circulating tumour cells. The objective of this study was to evaluate the feasibility and toxicity of peripheral blood CD34+ stem cell-derived NK cell infusion after radical hepatectomy for HCC. METHODS AND ANALYSIS This is an open-label, single-arm, single-centre phase I study. Patients who have undergone initial hepatectomy for HCC with three or more risk factors for recurrence (≥10 ng/mL of Alpha fetoprotein (AFP), ≥360 mAU/mL of PIVKA-II, multiple tumours and ≥3 peripheral blood circulating tumour cells) will be enrolled and be treated with three peripheral blood CD34+ stem cell-derived NK cell infusions every 3 months. The primary endpoint will be safety assessment including the type and severity of adverse events, frequency of occurrence and duration of occurrence. The secondary endpoints will include survival, effect of immune response and clinical laboratory test results. ETHICS AND DISSEMINATION Ethical approval of the trial was obtained from the Certified Committee for Regenerative Medicine Hiroshima University in Japan. The trial results will be shared with the scientific community at international conferences and by publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER jRCTb060200020.

STAT1 is associated with NK cell dysfunction by downregulating NKG2D transcription in chronic HBV-infected patients. Immunobiology 2022; 227:152272. [PMID: 36122437 DOI: 10.1016/j.imbio.2022.152272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 07/30/2022] [Accepted: 09/01/2022] [Indexed: 11/23/2022]
Abstract
PURPOSE Natural killer (NK) cells are key players in the immune system, however, the exact mechanism of NK cell dysfunction during HBV infection remains poorly defined. METHODS Hepatitis B envelope antigen-negative (HBeAg-, n = 19) chronic hepatitis B infection (CHB) patients, HBeAg-positive (HBeAg+, n = 20) CHB patients, HBV-related hepatocellular carcinoma (HBV-HCC, n = 12) patients and healthy blood donors (HD, n = 20), were enrolled in our study. The phenotype and function of the corresponding NK cells of these subjects were then determined. NK cells were cocultured with HBV to assess whether HBV influences the activation of STAT1. Receptors, proliferation, apoptosis rate, and cytotoxicity of NK-92 cells were detected after STAT1 overexpression and knockdown. The relationship between STAT1 and NKG2D promoter was determined by luciferase assay. RESULTS The levels of NKG2D and STAT1 were the lowest in the HBV-HCC group compared with the HD group, followed by the HBeAg+ group and then the HBeAg- group, respectively. Interestingly, STAT1 levels were positively correlated with NKG2D expression and HBeAg status. Furthermore, STAT1 directly bound to the NKG2D promoter to regulate the transcription and expression of NKG2D. Finally, the results also suggested that knockdown of STAT1 can inhibit proliferation, increase apoptosis rate of NK-92 cells and impair cytotoxicity of NK-92 cells. CONCLUSION STAT1 is correlated with NK cell dysfunction by downregulating NKG2D transcription in HBV-infected patients. Our findings demonstrate that STAT1 is an important and positive regulator of NK cells, which could provide a potential immunotherapy target for CHB.

Abstract
INTRODUCTION/AIMS Immunophenotypes are related to the therapeutic efficacy of specific immunomodulating agents in patients with myasthenia gravis (MG), but the relationship of immunophenotype to the presence or absence of thyroid antibodies is unknown. This study aims to evaluate differences in the immunophenotypes between MG patients with and without thyroid antibody (TAb) positivity to provide insight for future targeted immunotherapies. METHODS This retrospective observational study included 48 MG patients with acetylcholine receptor antibody (AchR-Ab), of which 15 (31.25%) were TAb positive. Ocular MG (OMG) was defined as ocular-only manifestations for the duration for which records were available. Peripheral lymphocyte subpopulations were measured by flow cytometry. RESULTS TAb positive patients appeared to have a higher prevalence of OMG than TAb negative patients (53.33% vs. 24.24%, P = 0.048). Percentages of B cells (mean difference (MD) = 6.16, 95% confidence interval (CI): 1.91 to 10.40, P = 0.007) and CD8 + CD28+ cells (MD = 15.14, 95%CI: 5.17 to 25.11, P = 0.013) were higher in TAb positive patients than those in TAb negative patients, while AChR-Ab titers (MD = -6.49 nmol/L, 95%CI: -9.29 to -3.70, P < 0.001), percentages of T cells (MD = -6.43, 95%CI: -11.92 to -0.94, P = 0.023), CD3 + HLA-DR+ cells (MD = -6.47, 95%CI: -12.31 to -0.63, P = 0.031) and CD8+ T cells (MD = -6.60, 95%CI: -9.86 to -3.34, P < 0.001) were lower. DISCUSSION The immunophenotypes of MG patients with and without TAb positivity were significantly different, suggesting that their sensitivity to immunotherapy may be different. Further studies focused on differences between TAb positive and TAb negative MG patients in their responses to specific immunotherapies are needed to support our exploratory findings.

Abstract
BACKGROUND The roles of CD56bright and CD56dim natural killer (NK) subsets in the viral clearance and inflammatory processes of hand, foot, and mouth disease (HFMD) remain undefined. METHODS A total of 39 HCs and 55 patients were enrolled to analyze peripheral CD56bright and CD56dim NK cells according to cell number, surface receptors, cytotoxic activities, and cytokine production. The plasma concentrations of IL-2, IL-6, IL-10, IFN-γ, TNF-α,and MCP-1 were detected using ELSA. RESULTS Peripheral blood NK cells was significantly lower in severe patients than in HCs due to the dramatic loss of CD56dim NK cells with no changes in the cell count of CD56bright NK cells. For mild patients, decreased NKp46 expression coincided with enhanced cytolysis (CD107a, GNLY, and GrB) in CD56dim NK cells and decreased NKG2A expression with enhanced IL-10 production in CD56bright NK cells. In contrast, severe patients showed the dominant expression of NKG2A and decreased expression of NKG2D accompanied by cytotoxic dysfunction in CD56dim NK cells. Imbalanced receptor expression coincided with the increased concentrations of TNF-α in CD56bright NK cells. Moreover, EV71+ patients showed significantly decreased counts of CD56dim NK cells with cytolysis dysfunction, displayed cytokine hypersecretion in CD56bright NK cells, while the EV71- patients displayed significantly higher plasma cytokine concentrations. The changes in the immune function of NK subsets and their subpopulations were closely related to clinical inflammatory parameters. CONCLUSIONS Low-frequency, exhausted immune status of CD56dim NK cells and disordered inflammatory cytokine secretion of CD56bright NK cells were associated with the progression of severe HFMD, especially in EV71-infected patients. This promoted the severity of inflammatory disorders, leading to enhanced disease pathogenesis.

Abstract
NK cells play crucial roles in defending against persistent HBV. However, NK cells present dysfunction in chronic hepatitis B virus (CHB) infection, and the associated mechanism is still not fully understood. Except for the regulatory receptors, NK cells could also be regulated by the surface and intracellular pattern recognition receptors (PRRs). In the present study, we found that the level of the adaptor of DNA sensor STING in NK cells was significantly decreased in HBeAg-negative CHB patients, and it was positively associated with the degranulation ability of NK cells. Compared to NK cells from healthy donors, NK cells from HBeAg-negative CHB patients displayed a lower responsiveness to cGAMP stimulation. Further investigation showed that HBsAg could inhibit the STING expression in NK cells and suppress the response of NK cells to cGAMP. Significantly, STAT3 was identified to be a transcription factor that directly regulated STING transcription by binding to the promoter. In addition, STAT3 positively regulated the STING associated IFN-α response of NK cells. These findings suggested that STING is an important adaptor in NK cell recognition and activation, while HBsAg disturbs NK cell function by the STAT3-STING axis, providing a new mechanism of NK disability in HBeAg-negative CHB infection.

Abstract
Recent evidence has shown that natural killer (NK) cells have an immunoregulatory function in the pathogenesis of myasthenia gravis (MG). In this study, the phenotype and function of NK cell subsets in peripheral blood of new-onset MG (N-MG) and stable MG (S-MG) patients were explored. Circulating CD56dim and CD56bright NK cells were increased and decreased, respectively, in patients with N-MG and S-MG compared with healthy control (HC). Moreover, all circulating NK cell subsets from N-MG patients showed significantly lower expression of activating receptor NKG2D and production of Interferon (IFN) -γ than that from HC. The killing effects of NK cells on CD4+ T cells and Tfh cells were impaired in MG patients, whereas, they promoted the differentiation and activation of Tfh cells. These data indicated that the immune-regulation of NK cells on CD4+ T cells and Tfh cells in MG patients was abnormal, which may contribute to the immune-pathological mechanism of MG.

Abstract
With the global spread of coronavirus disease 2019 (COVID-19), the important role of natural killer (NK) cells in the control of various viral infections attracted more interest, via non-specific activation, such as antibody-dependent cell-mediated cytotoxicity (ADCC) and activating receptors, as well as specific activation, such as memory-like NK generation. In response to different viral infections, NK cells fight viruses in different ways, and different NK subsets proliferate. For instance, cytomegalovirus (CMV) induces NKG2C + CD57 + KIR+ NK cells to expand 3-6 months after hematopoietic stem cell transplantation (HSCT), but human immunodeficiency virus (HIV) induces KIR3DS1+/KIR3DL1 NK cells to expand in the acute phase of infection. However, the similarities and differences among these processes and their molecular mechanisms have not been fully discussed. In this article, we provide a summary and comparison of antiviral mechanisms, unique subset expansion and time periods in peripheral blood and tissues under different conditions of CMV, HIV, Epstein-Barr virus (EBV), COVID-19 and hepatitis B virus (HBV) infections. Accordingly, we also discuss current clinical NK-associated antiviral applications, including cell therapy and NK-related biological agents, and we state the progress and future prospects of NK cell antiviral treatment.

Highly activated TRAIL + CD56 bright NK cells are associated with the liver damage in HBV-LC patients. Immunol Lett 2021; 232:9-19. [PMID: 33515618 DOI: 10.1016/j.imlet.2020.12.008] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 12/16/2020] [Accepted: 12/17/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Chronic hepatitis B-related liver cirrhosis(HBV-LC)is the most common cirrhosis in China, which is characterized as liver damage and high mortality. We aim to investigate the characteristics of TRAIL+NK cells in patients with HBV-LC and their relationship with liver damage in patients with HBV-LC. METHODS Thirty cases each of chronic hepatitis B (CHB), HBV-related compensated liver cirrhosis (HBV-CLC) and HBV-related decompensated liver cirrhosis (HBV-DLC) patients were recruited in this study. Thirty age-and sex-matched healthy individuals were recruited as healthy controls (HCs). NK cell phenotypes were determined using flow cytometry. Serum chemokine concentrations were ascertained using the CBA Flex set. Cell apoptosis was analyzed using the Annexin V-PE/7-AAD apoptosis Kit. RESULTS CD56bright NK cells increased, but CD56dim NK cells reduced in HBV-LC patients. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) was mainly expressed on CD56bright NK cells. As the degree of liver damage increased, the frequency and activation of total TRAIL+NK cells and TRAIL+NK cell subsets continued to increase, especially in the HBV-LC patients. Furthermore, the difference in frequency and activation of total TRAIL+NK cells between the HBV-CLC and HBV-DLC groups was mainly due to the highly activation and increase of TRAIL+CD56bright NK cells. With the increasing degree of liver damage, CXCR3-associated chemokines (including CXCL9, CXCL10 and CXCL11) were constantly increased, particularly in the HBV-DLC group. The expression of CXCR3 on CD56bright NK cells was almost 100 % in all enrolled cohorts. CXCR3-associated chemokines were negatively correlated with liver function and positively correlated with fibrosis degree. TRAIL+CD56bright NK cells were negatively correlated with liver function, and positively correlated with fibrosis degree and CXCR3-associated chemokines. The apoptosis of K562 cells and hepatocytes was suppressed partially by the TRAIL-neutralizing antibodies. CONCLUSIONS The increase of CXCR3-related chemokines (including CXCL9, CXCL10 and CXCL11) might be related to the migration of TRAIL+ CD56bright NK cells to the liver. Highly activated TRAIL+ CD56bright NK cells were associated with the liver damage in HBV-LC patients. These findings may provide new perspectives and theoretical basis for future immunotherapy of HBV-LC patients.
