Mapping the heterogeneity of histone modifications on hepatitis B virus-DNA using liver needle biopsies obtained from chronically infected patients.

J Virol 2019 Feb 20. Epub 2019 Feb 20.

Novartis Institutes for Biomedical Research, Infectious Diseases, Emeryville, CA, USA.

Covalently closed circular DNA (cccDNA) forms the basis for replication and persistence of hepatitis B virus (HBV) in the chronically infected liver. We have previously shown that viral transcription is subject to regulation by posttranslational modifications (PTMs) of histone proteins bound to cccDNA through analysis of HBV infected cell lines. We now report the successful adaptation of this chromatin immunoprecipitation-sequencing (ChIPseq) approach for analysis of fine-needle patient liver biopsy specimens to investigate the role of histone PTMs in chronically HBV-infected patients.

Restriction of hepatitis B virus replication by c-Abl-induced proteasomal degradation of the viral polymerase.

Sci Adv 2019 Feb 6;5(2):eaau7130. Epub 2019 Feb 6.

School of Life Science and Technology, ShanghaiTech University, Shanghai 201210, China.

About 257 million people with chronic infection of hepatitis B virus (HBV) worldwide are at high risk of developing terminal liver diseases. Reactivation of virus replication has been frequently reported in those patient populations receiving imatinib (an Abl kinase inhibitor) or bortezomib (a proteasome inhibitor) to treat concurrent diseases, but the underlying mechanism for this reactivation is unknown. We report that the HBV polymerase protein is recruited by Cdt2 to the cullin-RING ligase 4 (CRL4) for ubiquitination and proteasome degradation and that this process is stimulated by the c-Abl nonreceptor tyrosine kinase.

Hepatitis B virus-like particles expressing Plasmodium falciparum epitopes induce complement-fixing antibodies against the circumsporozoite protein.

Vaccine 2019 Feb 14. Epub 2019 Feb 14.

Victorian Infectious Diseases Reference Laboratory (VIDRL), Melbourne Health, The Peter Doherty Institute, Melbourne, Victoria 3000, Australia; Royal Melbourne Institute of Technology (RMIT) University, School of Science, Melbourne, Victoria 3001, Australia. Electronic address:

The repetitive structure of compact virus-like particles (VLPs) provides high density displays of antigenic sequences, which trigger key parts of the immune system. The hepatitis B virus (HBV) and human papilloma virus (HPV) vaccines exploit the assembly competence of structural proteins, which are the effective immunogenic components of the prophylactic HBV and HPV vaccines, respectively. To optimize vaccine designs and to promote immune responses against protective epitopes, the "Asp-Ala-Asp-Pro" (NANP)-repeat from the Plasmodium falciparum circumsporozoite protein (CSP) was expressed within the exposed, main antigenic site of the small HBV envelope protein (HBsAgS); this differs from the RTS,S vaccine, in which CSP epitopes are fused to the N-terminus of HBsAgS.

VaccHemInf project: protocol for a prospective cohort study of efficacy, safety and characterisation of immune functional response to vaccinations in haematopoietic stem cell transplant recipients.

BMJ Open 2019 Feb 15;9(2):e026093. Epub 2019 Feb 15.

Département des Maladies Infectieuses et Tropicales, Hospices Civils de Lyon, Lyon, France.

Introduction: Immune reconstitution after haematopoietic stem cell transplantation (HSCT) is a complex and dynamic process, varying from a state of nearly complete immunosuppression to an expected full immune recovery. Specific vaccination guidelines recommend reimmunisation after HSCT but data regarding vaccine efficacy in this unique population are scarce. New immune functional assays could enable prediction of vaccine response in the setting of HSCT. Read More
