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

Adeno-associated virus (AAV)-PHP.B, a capsid variant of AAV serotype 9, is highly permeable to the blood-brain barrier. A major obstacle to the systemic use of AAV-PHP.B is the generation of neutralizing antibodies (NAbs); however, temporal profiles of NAb production after exposure to AAV-PHP.B, and the influence on later AAV-PHP.B administration, remains unknown. To address these, AAV-PHP.Bs expressing either GFP or mCherry by neuron-specific or astrocyte-specific promoters were intravenously administered to mice at various intervals, and brain expression was examined. Injection of two AAV-PHP.Bs, separated temporally, showed that as little as a 1-day interval between injections resulted in a significant decrease in expression of the second transgene, with a complete loss of expression after 7 days, paralleling an increase in serum NAb titers. Brain parenchymal injection was explored to circumvent the presence of NAbs. Mice systemically pre-treated with an AAV-PHP.B were injected intra-cerebrally with an AAV-PHP.B expressing GFP. After 2 weeks, marked GFP expression in the cerebellum was evident, showing that pre-existing NAbs did not affect the AAV-PHP.B directly injected into the brain. In contrast, reversing the injection order, i.e., cerebellar injection followed by systemic injection, completely eliminated expression of the second transgene. We confirmed that intra-cerebellar injection produced NAbs in the serum, but not in the cerebrospinal fluid (CSF). Our results indicate that the preclusion of brain transduction by a second AAV-PHP.B administration begins from the first day following systemic injection and is established within 1 week. Serum NAbs can be avoided by directly injecting AAV-PHP.Bs into brain tissue.
