Innate immune recognition and evasion strategies of hepatitis B virus: from DNA to RNA and viral proteins.
Review in Frontiers in immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Innate immunity constrains the hepatitis B virus (HBV) by sensing pathogen-associated molecular patterns (PAMPs) and inducing type I/III interferons and interferon-stimulated genes. This review synthesizes molecular mechanisms by which HBV nucleic acids and proteins are detected by pattern recognition receptors (PRRs) and how the virus evades such surveillance. At the DNA level, covalently closed circular DNA (cccDNA) persists as a chromatin-like episome with low immunogenicity; cGAS-STING signaling is functionally dampened, whereas nuclear interferon-inducible protein 16(IFI16) and cytoplasmic/nuclear ABCF1 bind cccDNA to repress transcription, and APOBEC3A-mediated deamination requires robust interferon signaling. At the RNA level, TLR3/7/8 and retinoic acid-inducible Gene I(RIG-I) sense circulating HBV RNA and 5'-triphosphate pregenomic RNA, respectively. HBV counteracts RIG-I-like receptor (RLR) pathways through ADAR1 editing, TIAR-dependent translational control, and a metabolic checkpoint involving lactate-MAVS/hexokinase, whereas spliced viral RNAs (svRNAs) have emerged as immunologically relevant species. At the protein level, Hepatitis B Surface Antigen (HBsAg) impairs interferons (IFN) induction by blocking the TAK1-TAB2-NF-κB/IRF axis; Hepatitis B Virus X Protein (HBx) sustains cccDNA transcription via DDB1-directed Smc5/6 degradation and broadly suppresses PRR/IFN signaling, with TRIM25 acting as a host restriction factor. These insights nominate combinatorial strategies-PRR agonists (TLR/STING), MAVS sensitization, metabolic disinhibition, pharmacological disruption of the HBx-DDB1 axis, and reinforcement of IFI16/ABCF1-to achieve functional control of cccDNA and advance curative hepatitis B virus (HBV) therapy.
