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 intranasal pathway is a promising antibody delivery route for the treatment of neurological diseases, but the mechanisms mediating nose-to-brain/spinal cord transport are poorly understood. The aim of our study was to determine if the transport of antibodies can pharmacologically be modulated in the mouse CNS. The pharmacokinetics and distribution of recombinant antibodies were followed in brain and spinal cord homogenates and biofluids by ELISA and immunofluorescence. A non-CNS antigen-binding antibody (FG12) was used to monitor target-independent transport whereas 11C7 mAb, neutralizing the myelin-associated growth inhibitor Nogo-A, was applied to induce CNS target-dependent neuronal growth response. Fast axonal transport/neuronal activity were inhibited with Lidocaine pre-treatment on the olfactory mucosa. Antibody uptake was enhanced across the olfactory epithelium with the co-administration of the cell-penetrating peptide Penetratin. Growth signalling pathways were examined by Western blotting. FG12 was detected in the brain and spinal cord as early as 30 ​min after intranasal administration. After 1 ​h, the concentration of FG12 rapidly declined in all CNS areas and was back to baseline values at 24 ​h. Lidocaine prevented the early rise in FG12 concentration in the spinal cord. This effect was not observed in the brain. Penetratin allowed to maintain the elevation of FG12 and to activate 11C7-induced growth signalling in the spinal cord at 24 ​h. Our data suggest that the pharmacological modulation of transport mechanisms in the nose-to-CNS pathways may allow to control the therapeutic effects of antibodies in neurological diseases.
