However, it remains difficult to eradicate the cccDNA of HBV in hepatocyte nuclei. Thus, serological biomarkers such as HBsAg, HBV DNA, and HBcrAg have been established to estimate HBV replication activity, predict therapeutic responses, and assess the risk of HCC development.&lt;span&gt;&lt;sup&gt;4, 5&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;Although the currently available quantitative HBsAg assay has been proven to correlate with serum HBV DNA and intrahepatic cccDNA levels,&lt;span&gt;&lt;sup&gt;6&lt;/sup&gt;&lt;/span&gt; it cannot distinguish HBsAg in terms of HBV virions and noninfectious SVPs. Hepatitis B virus envelope proteins include three distinct types of HBsAg: S-HBsAg, M-HBsAg, and L-HBsAg. The HBV particles in a patient's blood include infectious Dane particles containing viral DNA and SVPs. The SVPs are composed mainly of S-HBsAg and are 1000 times more abundant than Dane particles, which are composed primarily of M-HBsAg protein. To accurately assess disease status, HBV virions must be closely monitored and clearly distinguished from SVPs.&lt;/p&gt;&lt;p&gt;Hepatitis B surface antigens are heavily glycosylated with N-glycans and O-glycans.&lt;span&gt;&lt;sup&gt;7, 8&lt;/sup&gt;&lt;/span&gt; Whole-glycan structural analyses have revealed that the PreS2 domain on M-HBs, but not on L-HBs, contain a highly conserved O-glycosylated site in genotype C.&lt;span&gt;&lt;sup&gt;9, 10&lt;/sup&gt;&lt;/span&gt; A recombinant monoclonal antibody against this HBsAgGi was then generated using an O-glycosylated PreS2 peptide. Unlike conventional HBsAg testing, which recognizes the entirety of viral particles, HBsAgGi specifically identifies infectious HBV particles containing M-HBsAg, that is, Dane particles containing DNA and RNA. Hepatitis B antigen glycan isomer testing is now commercially available and can be measured in patient serum with an enzyme-linked immunosorbent assay kit featuring a monoclonal antibody to O-glycosylated PreS2 on M-HBsAg. Evidence on the clinical utility of HBsAgGi is now growing.&lt;/p&gt;&lt;p&gt;Recent studies have described correlations of HBsAgGi with other HBV-associated markers along with HBsAgGi kinetics.

This study examined the detrimental effects of liver fibrosis on the antitumor functions of liver natural killer (NK) cells and the interleukin-33 (IL-33) signaling pathway.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>Our investigation, anchored in both human physiologies using living and deceased donor livers and the carbon tetrachloride (CCl₄)-induced mouse fibrosis model, aimed to show a troubling interface between liver fibrosis and weakened hepatic immunity.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The Fibrosis-4 (FIB-4) index emerged as a salient, non-invasive prognostic marker, and its elevation correlated with reduced survival and heightened recurrence after HCC surgery even after propensity matching (<i>n</i> = 385). We established a strong correlation between liver fibrosis and liver NK cell dysfunction by developing a method for extracting liver NK cells from the liver graft perfusate. Furthermore, liver fibrosis ostensibly disrupted chemokines and promoted IL-33 expression, impeding liver NK cell antitumor activities, as evidenced in mouse models. Intriguingly, our results implicated IL-33 in diminishing the antitumor responses of NK cells. This interrelation, consistent across both mouse and human studies, coincides with clinical data suggesting that liver fibrosis predisposes patients to an increased risk of HCC recurrence.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Our study revealed a critical relationship between liver fibrosis and compromised tumor immunity, emphasizing the potential interference of IL-33 with NK cell function. These insights advocate for advanced immunostimulatory therapies targeting cytokines, such as IL-33, aiming to bolster the hepatic immune response against HCC in the context of liver fibrosis.</p>\u0000 </section>\u0000 </div>","PeriodicalId":12987,"journal":{"name":"Hepatology Research","volume":"55 1","pages":"115-129"},"PeriodicalIF":3.9,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/hepr.14102","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141971005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
