Differential regulation of mTOR activity in retinal ganglion cells underlies their distinct susceptibility to ischemia/reperfusion.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Retinal ischemia/reperfusion (I/R) injury drives progressive retinal ganglion cell (RGC) loss, yet mechanisms underlying neuronal type-specific vulnerability remain unclear. Using a mouse model of bilateral common carotid artery ligation, we observe decreased vessel density in the inner retina following I/R. Here, the total RGCs exhibit much more cell loss than the intrinsic photosensitive RGCs (ipRGCs). This disparity is parallel with their different mTOR activity: for ipRGCs, the mTOR activity is much higher than the total RGCs both before and after I/R. Pharmacological experiments reveal that, mTOR activation in total RGCs and high mTOR activity maintenance in ipRGCs promote rapamycin to protect the total RGCs and ipRGCs against I/R injury, respectively. Notably, the protective effects of rapamycin on total RGCs and ipRGCs manifest under different light conditions. Our findings bridge the type-specific mTOR regulation in RGCs and their distinct susceptibility to I/R injury, which offers new insights into further targeted neuroprotection.
