Hepatitis B virus (HBV) is responsible for the increasing burden of hepatitis worldwide, with an estimated 296 million people living with it. at risk of developing liver disease and cancer. Although current treatments for chronic hepatitis B (CHB), including its oral nucleo(t)ide analogs and systemic interferon alpha, are considered ineffective, the path to a definitive cure for this viral disease is very difficult. The lack of adequate laboratory animal models supporting HBV infection and the development of liver disease is one of the major obstacles. in antibiotic development. For more than forty years, disease models of the eastern groundhog and groundhog hepatitis virus have been used to study the immunopathogenesis of HBV and develop new antiviral drugs against CHB. This animal model has several advantages that make it useful for conducting basic and translational studies of HBV. Previous review articles focused on the importance of this animal model in relation to HBV replication, pathogenesis, and response. In this article, we review drug development studies and clinical trials of targeted drugs, immunomodulators, vaccines, and inhibitors of viral entry, gene expression, and antigen presentation in the groundhog model of CHB from the 2014 to present and discuss its importance. for clinical trials in patients.

Hepatitis B virus (HBV) is a hepatotropic, non-cytolytic DNA virus classified in the genus Orthohepadnavirus in the family Hepadnaviridae [1, 2]. HBV is a nucleocapsid-enveloped virus that has a 3.2 kilobase (kb) long genome of a double-stranded (ds) or circular DNA fragment (rc) [1, 3]. HBV enters the hepatocytes through a low concentration of virions in the heparin sulfate proteoglycans (HSPGs) on the cell surface, followed by high-affinity binding of the HBV surface protein ( HBsAg) with fatty acid transporter, sodium taurocholate cotransporter. protein (NTCP) [4, 5]. In addition to NTCP as an important receptor, the epidermal growth factor receptor (EGFR) has been identified as a co-receptor for HBV entry into hepatocytes [6]. After binding and internalization of HBV virions, the genome in the nucleocapsid is transported into the nucleus to complete the rcDNA into a closed circular DNA. together (cccDNA) by host DNA polymerase II and the repair machinery. Cellular DNA [7, 8]. The cccDNA is the reservoir of the HBV genome in the nucleus and is used for the translation of viral genomic and subgenomic RNAs. The 3.5-kb transcript of pregenomic RNA (pgRNA) serves as a template for nascent viral rcDNA, but also as mRNA for viral polymerase/reverse transcriptase translation and basic protein The HBV precore protein is translated from the precore mRNA, another viral transcript that is longer than pgRNA, and serves as a precursor to the soluble HBV e antigen (HBeAg) and recently the PreC antigen expression [9, 10]. In addition, the large (L-HBsAg), medium (M-HBsAg), and small (S-HBsAg) proteins are translated from 2.4 kb and 2.1 kb transcripts, while the HBV x antigen ( HBxAg) is translated from about 0.7 kb. translation [7, 11]. pgRNA together with viral polymerase/reverse transcriptase are encapsulated into newly formed nucleocapsids containing core protein (HBcAg). Encapsidation initiates the reverse transcription of pgRNA into negative DNA followed by positive DNA replication [3]. These mature nucleocapsids containing HBV rcDNA are coated by HBsAg proteins and secreted as intact virions or recycled into the nucleus for replenishment of the cccDNA pool [12, 13]. Recent studies have investigated the integration of the HBV genome into the chromosomal DNA of the host and found that this viral DNA is another source of HBsAg [14]. The increased viral load present during chronic hepatitis B (CHB) facilitates this combination and, as a second reservoir of HBsAg (in addition to cccDNA), adds to the challenge of defeating weak T cells due to prolonged exposure to viral antigens. Other studies are needed to confirm the properties of HBsAg derived from HBV DNA synthesis and confirm its involvement in immunopathogenesis.

The World Health Organization (WHO) has identified HBV infection as a serious public health problem affecting approximately 296 million people. worldwide are carriers of HBV infection [15]. Liver disorders related to HBV, such as CHB, fibrosis, cirrhosis and primary cancer or hepatocellular carcinoma (HCC), account for approximately one million deaths each year, more than any other disease. infections such as tuberculosis and acquired immunodeficiency (AIDS) caused by bacteria. with Mycobacterium tuberculosis or human immunodeficiency virus (HIV), respectively [16]. In the absence of medical treatment, the reduction of HBV infection currently depends on vaccination. In the last three decades, vaccination programs around the world have made great strides in protecting the majority of the population from HBV, especially those based on the three -dose regimen of HBsAg vaccine [17]. Current treatments against CHB are limited to oral (NA) and subcutaneous (sc) nucleos(t)ide analogs, pegylated interferon-alpha (pegIFN-α) [18]. Because NA does not specifically target cccDNA and only inhibits HBV polymerase, prolonged or lifelong administration is required to prevent relapse. viral rebound after treatment. Entecavir (ETV), tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide fumarate (TAF) are currently recommended as first-line drugs for NA treatment against CHB. They are good at managing the viral process without the development of drugs, but the percentage of patients who achieve a functional solution, defined as the serum HBV DNA and HBsAg cannot be detected or there is no seroconversion, is <10% even after prolonged treatment [19]. In contrast, the pegIFN-α trial for one year mediates a disease response without treatment in approximately 10-20% of patients. Although this pleiotropic cytokine directly targets the cccDNA and induces natural (NK) cell activity [20], the complications involved in its specific administration include treatment complications and serious side effects resulting in low the patient's compliance. Many factors, including age, HBeAg status, HBV genotype, and serum levels of HBV rcDNA and the enzyme alanine transaminase (ALT), influence individual response to pegIFN therapy. -α [21]. Therefore, future antiretroviral drugs should address both the safety and efficacy concerns of existing anti-HBV therapies. now to try shorter and more effective treatments for CHB. In this context, several antiviral agents (DAAs) have been developed to target specific steps in the HBV cycle, including viral entry, capsid formation, and protein translation and release [22, 23]. . However, the failure of these DAAs to directly target ccDNA supports the challenge of viral rebound after treatment. Since the HBV pathogenesis and the progression of liver disease depend on the use of antiviral immunity, as explained in more detail below, many methods have been developed to cope with the failure of the immune response. during CHB, including agonistic stimulation of the immune system, transfer of T cells and therapy. injection Some candidates, including both DAA and immunomodulators, have shown promise in clinical studies in HBV animal models and are currently being evaluated in clinical trials in CHB patients.

Among the various challenges involved in the study of HBV pathogenesis and the development of therapeutics against HCB, the lack of a small, immunocompetent, HBV research animal model is particularly important. The eastern groundhog (Marmota monax), specifically or experimentally infected with groundhog hepatitis virus (WHV), develops an immunopathogenesis and clinical symptoms similar to those observed during HBV infection in humans [24]. For more than forty years, this animal model has been used to understand the biology of HBV, but
