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

The pathogenesis of Alzheimer's disease is characterized by aggregation of the amyloid-beta protein (Abeta) into neurotoxic plaques. Recent in vivo studies have suggested the non-proteolytic clearance of Abeta via receptor-mediated transport across the blood-brain barrier (BBB). The aim of this study was to investigate the role of P-glycoprotein (Pgp) and the low-density lipoprotein receptor-related protein (LRP) in Abeta efflux across the BBB. We developed an in vitro BBB-like model using Madin-Darby Canine Kidney (MDCK) cells seeded on filters separating apical (blood) and basolateral (brain) compartments. MDCK cells were stably transfected with Pgp or mLRP4, an LRP mini-receptor. When compared to empty vector-transfected cells, MDCK-Pgp cells did not transcytose radiolabeled Abeta in the basolateral-to-apical direction. MDCK-mLRP4 cells were found to endocytose and degrade, but not to trasncytose intact radiolabeled Abeta. These results implicate LRP as a mediator of Abeta degradation, but indicate that overexpression of LRP or Pgp alone is insufficient for non-proteolytic transcytosis of intact Abeta.
