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

backgroundAlzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the accumulation of amyloid-β plaques, tau hyperphosphorylation, and neuroinflammation. The choroid plexus (ChP), serving as the blood-cerebrospinal fluid-brain barrier, plays essential roles in immune response to stress and brain homeostasis. However, the cellular and molecular contributions of the ChP to AD progression remain inadequately understood.

methodsTo elucidate the molecular abnormalities during the early stages of AD, we acquired single-cell transcription profiling of ChP from APP/PS1 mice with early-stage of Aβ pathology and litter-mate controls. The transcriptional alterations that occurred in each cell type were identified by differentially expressed genes, cell-cell communications and pseudotemporal trajectory analysis. The findings were subsequently validated by a series of in situ and in vitro assays.

resultsWe constructed a comprehensive atlas of ChP at single-cell resolution and identified six major cell types and immune subclusters in male mice. The majority of dysregulated genes were found in the epithelial cells of APP/PS1 mice in comparison to wild-type (WT) mice, and most of these genes belonged to down-regulated module involved in mitochondrial respirasome assembly, cilium organization, and barrier integrity. The disruption of the epithelial barrier resulted in the downregulation of macrophage migration inhibitory factor (MIF) secretion in APP/PS1 mice, leading to macrophage activation and increased phagocytosis of Aβ. Concurrently, ligands (e.g., APOE) secreted by macrophages and other ChP cells facilitated the entry of lipids into ependymal cells, leading to lipid accumulation and the activation of microglia in the brain parenchyma in APP/PS1 mice compared to WT controls.

conclusionsTaken together, these data profiled early transcriptional and cellular abnormalities of ChP within an AD mouse model, providing novel insights of cerebral vasculature into the pathobiology of AD.
