Unique Properties of the Large Antigen of Hepatitis Delta Virus [PDF]

Journal of Virology, 1999
ABSTRACT The large form of the hepatitis delta virus (HDV) protein (L) can be isoprenylated near its C terminus, and this modification is considered essential for particle assembly. Using gel electrophoresis, we separated L into two species of similar mobilities. The slower species could be labeled by the incorporation of [

High Prevalence of Active HDV Infection Among HBsAg‐Positive Patients in Urban and Rural Areas in Gabon: A Cross‐Sectional Retrospective Study

Health Science Reports, Volume 9, Issue 2, February 2026.
ABSTRACT Background HDV, a defective virus dependent on hepatitis B for assembly, can lead to severe liver diseases and an increased risk of progressing to complications such as hepatocellular carcinoma. Given the high prevalence of HDV in Gabon, especially in central Africa, understanding the epidemiology and associated risks is crucial.

Alcohol Abstinence Does Not Fully Reverse Abnormalities of Mucosal-Associated Invariant T Cells in the Blood of Patients With Alcoholic Hepatitis [PDF]

, 2019
OBJECTIVES: Alcoholic hepatitis (AH) develops in approximately 30% of chronic heavy drinkers. The immune system of patients with AH is hyperactivated, yet ineffective against infectious diseases.

Construction of Reverse Genetics System for Feline Calicivirus FCV‐BJ616 and Proteomic Analysis

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
This study successfully isolated the FCV‐BJ616 strain derived from cats and established a reverse genetics system. In vivo experiments showed that rFCV‐BJ616 exhibits wild‐type virulence, leading to high fever, weight loss, and multi‐organ lesions in infected cats. Proteomic analysis indicated that both rFCV‐BJ616 and FCV‐BJ616 share similar regulatory

Tumor Immunotherapy and Microbiome: From Bench‐to‐Bedside Applications

MedComm, Volume 7, Issue 2, February 2026.
The microbiome is related to the efficacy of immunotherapy and can be utilized to predict the efficacy and adverse reactions of immunotherapy. Microbiome‐targeted intervention strategies can improve the efficacy of ICI, but necessitating more comprehensive exploration.

A virus-like particle of the hepatitis B virus preS antigen elicits robust neutralizing antibodies and T cell responses in mice [PDF]

, 2018
The preS antigen of hepatitis B virus (HBV) corresponds to the N-terminal polypeptide in the large (L) antigen in addition to the small (S) antigen. The virus-like particle (VLP) of the S antigen is widely used as a vaccine to protect the population from

Relating structure to function in the hepatitis delta virus antigen [PDF]

Journal of Virology, 1993
Hepatitis delta virus expresses two forms of a single protein, the small (delta Ag-S) and large (delta Ag-L) antigens, which are identical except for an additional 19 residues present at the C terminus of delta Ag-L. While delta Ag-S is required to promote genome replication, delta Ag-L potently inhibits this process and also facilitates packaging of ...

Ten‐Year Follow‐Up After 96 Weeks Treatment With Peginterferon Plus Tenofovir in Hepatitis D (HIDIT‐II): Improved Clinical Outcome After Combination Therapy

United European Gastroenterology Journal, Volume 14, Issue 1, February 2026.
ABSTRACT Background Chronic delta hepatitis represents a major health burden. Until recently, pegylated interferon‐alfa‐2a (PEG‐IFNα) therapy was the only treatment option for patients infected with hepatitis D virus (HDV). The aim of this study was to evaluate 10‐year long‐term clinical and virological outcomes after 96 weeks of treatment with PEG ...

Efficacy of a pre-S containing vaccine in patients receiving lamivudine prophylaxis after liver transplantation for chronic hepatitis B [PDF]

, 2007
Lamivudine monoprophylaxis against hepatitis B virus (HBV) reinfection after liver transplantation is associated with recurrence due to escape mutants and second generation recombinant HBV vaccine is not effective.

Distinct 5′ UTR Requirements for Translation of the Bicistronic X/P mRNA Among Avian Orthobornaviruses

Microbiology and Immunology, Volume 70, Issue 2, Page 80-90, February 2026.
ABSTRACT Orthobornaviruses express X and the phosphoprotein (P) from a bicistronic X/P mRNA, and these proteins regulate polymerase activity. In mammalian orthobornaviruses, the 5′ untranslated region (5′ UTR) of the X/P mRNA controls the translational balance between X and P and thereby promotes efficient replication.
