Changes in the Hepatitis B Surface Antigen Level According to the HBeAg Status and Drug Used in Long-term Nucleos(t)ide Analog-treated Chronic Hepatitis B Patients

open access: yesThe Korean Journal of Gastroenterology, 2021
Background/Aims: The HBsAg levels have been used to monitor the chronic hepatitis B (CHB) treatment response to antiviral therapy. On the other hand, it is unclear if the HBsAg quantification levels at each treatment point differ according to the HBeAg ...

Serum hepatitis B virus RNA levels as a predictor of HBeAg seroconversion during treatment with peginterferon alfa-2a

open access: yesVirology Journal, 2019
Background Hepatitis B e antigen (HBeAg) seroconversion represents an endpoint of treatment of chronic hepatitis B virus (HBV) infections. Methods We have studied whether levels of serum hepatitis B virus ribonucleic acid (HBV RNA) during pegylated ...

Seroprevalence of hepatitis B infection and associated risk factors among drug users in drop-in centers of Isfahan, Iran

open access: yesInternational Journal of Preventive Medicine, 2018
Background: Scientists perceive drug users (DUs) as a high-risk population for hepatitis B virus (HBV) infection. Effective strategies aiming at the reduction of HBV infection can be depicted when its epidemiological status is clearly defined.

Hepatitis B e antigen-negative chronic hepatitis B [PDF]

open access: yesHepatology, 2001
Summary HBeAg-negative CHB has now a worldwide distribution, developing in the course of HBeAg-positive chronic HBV infection during or after the phase of HBeAg loss and its seroconversion to anti-HBe. It is caused by replicating noncytopathic HBV mutants either unable to produce HBeAg (precore mutants) or with down-regulated transcription of the ...

Monoclonal Antibodies Specific for Hepatitis B e Antigen and Hepatitis B Core Antigen

open access: yesHybridoma, 2011
Despite effective vaccination programs in many countries, HBV infection is still a serious health problem throughout the world; more than 2 billion people have been infected with Hepatitis B virus (HBV). The serologic markers are crucial indicators in clinical diagnosis of HBV infection. The persistent presence of anti-HBc is associated with chronicity,

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Linearized hepatitis B surface antigen and hepatitis B core-related antigen in the natural history of chronic hepatitis B [PDF]

open access: yesClinical Microbiology and Infection, 2014
Changes in two novel HBV serological markers, linearized hepatitis B surface antigen (HQ-HBsAg) and hepatitis B core-related antigen (HBcrAg), in the natural history of chronic hepatitis B (CHB) have not been well characterized. Serum HQ-HBsAg and HBcrAg levels of 404 Asian treatment-naïve CHB patients were analysed in a cross-sectional manner ...

Neutralization of the PTX3/CD44 axis suppresses TGF‐β1 signaling in kidney fibrosis

open access: yesFEBS Letters, EarlyView.
This study investigates how the PTX3/CD44 axis promotes kidney fibrosis by activating TGF‐β1 signaling. We demonstrate that the neutralizing antibody WHC‐001 effectively inhibits this pathway, suppressing myofibroblast activation and partial epithelial–mesenchymal transition (EMT).

A recombinant human immunoglobulin with coherent avidity to hepatitis B virus surface antigens of various viral genotypes and clinical mutants.

open access: yesPLoS ONE, 2020
The hepatitis B virus (HBV) envelope is composed of a lipid bilayer and three glycoproteins, referred to as the large (L), middle (M), and small (S) hepatitis B virus surface antigens (HBsAg). S protein constitutes the major portion of the viral envelope
