A new anterograde trans-synaptic tracer based on Sindbis virus.
Article in Neural regeneration research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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
Mapping neural circuits is critical for understanding the structure and function of the nervous system. Engineered viruses are a valuable tool for tracing neural circuits. However, current tracers do not fully meet the needs for this approach because of various drawbacks, such as toxicity and characteristics that are difficult to modify. Therefore, there is an urgent need to develop a new tracer with low toxicity and that allows for long-term studies. In this study, we constructed an engineered Sindbis virus (SINV) expressing enhanced green fluorescent protein (EGFP) reporter gene (SINV-EGFP) and found that it had no significant difference in biological characterization compared with the wild-type Sindbis virus in BHK-21 cells and neurons in vitro. We injected the virus into the visual circuit of mouse brain and found that the virus infected neurons in the local injected site and anterogradely spread in the neural circuits. Although the efficiency of transmission was limited, the findings demonstrate that SINV can be used as a new anterograde tracer to map neural circuits in mouse brain and that it spreads exclusively in the anterograde direction. Further, use of SINV in mouse brain research will provide longer time windows for circuit tracing than is possible with herpes simplex virus and vesicular stomatitis virus tracers.
