Cell line-dependent release of quasi-enveloped hepatitis E virus reveals alternative Golgi-associated egress in the absence of pORF3.

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
Background: Hepatitis E virus (HEV) particles are released from infected cells in a quasi-enveloped form, typically via the multivesicular body (MVB) pathway, which is mediated by the viral accessory protein pORF3. However, cell-type specific aspects of this release mechanism remain poorly understood. Methods: We analyzed the release and envelopment characteristics of a pORF3-deficient genotype 3c HEV (HEVΔORF3) in comparison to wild-type HEV (HEVwt) in two human cell lines: hepatoma-derived PLC/PRF/5 and lung carcinoma-derived A549/D3 cells. Results: While viral release of HEVΔORF3 was strongly impaired in A549/D3 cells, PLC/PRF/5 cells supported efficient viral release despite the absence of pORF3. In PLC/PRF/5 cells, HEV particles retained quasi-envelopment and utilized an alternative, Golgi-associated egress pathway in the absence of pORF3. In contrast, A549/D3 cells did not support this compensatory release route. Conclusion: Our findings highlight a pronounced cell line-dependent variability in HEV release pathways, emphasizing the importance of cellular context in studies of HEV biology and antiviral strategies targeting virus egress.
