1 · What the graph read from it

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.

2 · The registry

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

Messenger RNA (mRNA) therapeutics delivered by lipid nanoparticles (LNPs) have advanced from concept to clinic at unprecedented speed, yet their promise for neurodegenerative diseases remains largely untapped. Currently intractable age-related proteinopathies such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis demand new therapies that combine molecular precision with scalable manufacturing. This review surveys recent advances in engineering LNPs that traverse the blood-brain barrier (BBB), evade innate immune surveillance, and achieve cell-selective expression in the ageing brain. We highlight emerging chemistries, including BBB-shuttling ionizable lipids, peptide-functionalized shells, and liver-detargeted formulations that enable systemic or minimally invasive delivery to the central nervous system (CNS) in animal models. Although no CNS-directed mRNA-LNP has yet reached clinical trials, first-in-human studies for rare metabolic disorders demonstrate favourable safety, manufacturability, and durable protein replacement. Drawing lessons from COVID-19 mRNA vaccines and ongoing liver-targeted programmes, we outline a translational roadmap for brain applications. Major hurdles that are critically assessed include efficient endosomal escape in aged neurons, heterogeneity of the senescent BBB, chronic-dose immunogenicity, and large-scale synthesis of next-generation lipids. Finally, we propose design rules and analytical standards to address outstanding knowledge gaps in expression durability and age-related BBB alterations. Together, these insights chart a path for engineering mRNA-LNP therapeutics capable of meeting the rising burden of neurodegenerative diseases in an ageing global population.
