Programmable self-replicating JEV nanotherapeutics redefine RNA delivery in ALS.
Review in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron degeneration, leading to paralysis and respiratory failure. Current therapies offer limited benefits, highlighting the need for novel therapeutic strategies. Antisense oligonucleotides (ASO) and CRISPR/Cas9 gene editing hold promise, but their effective delivery to the central nervous system (CNS) remains a significant challenge. Here, a potential approach involves utilizing engineered Japanese encephalitis virus (JEV) as a self-replicating nanocarrier for targeted ASO delivery to motor neurons. By leveraging JEV's natural neurotropism and "Trojan horse" mechanism of immune cell-mediated CNS entry, this strategy overcomes the blood-brain and blood-spinal cord barriers (BBB/BSCB). Incorporation of ASO sequences within the JEV genome facilitates co-packaging and sustained therapeutic delivery, while microRNA (miRNA)-mediated attenuation may enhance safety and CNS specificity. This theoretical framework offers a potential paradigm shift in CNS gene therapy for ALS and other neurodegenerative diseases by enabling efficient, targeted, and sustained ASO delivery. However, experimental validation remains critical to assess its safety and therapeutic efficacy.
