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

Brain development and function require uptake of essential omega-3 fatty acids in the form of lysophosphatidylcholine via major-facilitator superfamily transporter MFSD2A, a potential pharmaceutical target to modulate blood-brain barrier (BBB) permeability. MFSD2A is also the receptor of endogenous retroviral envelope syncytin-2 (SYNC2) in human placenta, where it mediates cell-cell fusion and formation of the maternal-fetal interface. Here, we report a cryo-electron microscopy structure of the human MFSD2A-SYNC2 complex that reveals a large hydrophobic cavity in the transporter C-terminal domain to occlude long aliphatic chains. The transporter architecture suggests an alternating-access transport mechanism for lipid substrates in mammalian MFS transporters. SYNC2 establishes an extensive binding interface with MFSD2A, and a SYNC2-soluble fragment acts as a long-sought-after inhibitor of MFSD2A transport. Our work uncovers molecular mechanisms important to brain and placenta development and function, and SYNC2-mediated inhibition of MFSD2A transport suggests strategies to aid delivery of therapeutic macromolecules across the BBB.
