An hepatitis B and D virus infection model using human pluripotent stem cell-derived hepatocytes.
Current culture systems available for studying hepatitis D virus (HDV) are suboptimal. In this study, we demonstrate that hepatocyte-like cells (HLCs) derived from human pluripotent stem cells (hPSCs) are fully permissive to HDV infection across various tested genotypes. When co-infected with the helper hepatitis B virus (HBV) or transduced to express the HBV envelope protein HBsAg, HLCs effectively release infectious progeny virions. We also show that HBsAg-expressing HLCs support the extracellular spread of HDV, thus providing a valuable platform for testing available anti-HDV regimens. By challenging the cells along the differentiation with HDV infection, we have identified CD63 as a potential HDV co-entry factor that was rate-limiting for HDV infection in immature hepatocytes. Given their renewable source and the potential to derive hPSCs from individual patients, we propose HLCs as a promising model for investigating HDV biology. Our findings offer new insights into HDV infection and expand the repertoire of research tools available for the development of therapeutic interventions.
期刊介绍：
EMBO Reports is a scientific journal that specializes in publishing research articles in the fields of molecular biology, cell biology, and developmental biology. The journal is known for its commitment to publishing high-quality, impactful research that provides novel physiological and functional insights. These insights are expected to be supported by robust evidence, with independent lines of inquiry validating the findings.
The journal's scope includes both long and short-format papers, catering to different types of research contributions. It values studies that:
Communicate major findings: Articles that report significant discoveries or advancements in the understanding of biological processes at the molecular, cellular, and developmental levels.
Confirm important findings: Research that validates or supports existing knowledge in the field, reinforcing the reliability of previous studies.
Refute prominent claims: Studies that challenge or disprove widely accepted ideas or hypotheses in the biosciences, contributing to the correction and evolution of scientific understanding.
Present null data: Papers that report negative results or findings that do not support a particular hypothesis, which are crucial for the scientific process as they help to refine or redirect research efforts.
EMBO Reports is dedicated to maintaining high standards of scientific rigor and integrity, ensuring that the research it publishes contributes meaningfully to the advancement of knowledge in the life sciences. By covering a broad spectrum of topics and encouraging the publication of both positive and negative results, the journal plays a vital role in promoting a comprehensive and balanced view of scientific inquiry.
