Long term therapeutic effects of icariin-loaded PLGA microspheres in an experimental model of optic nerve ischemia via modulation of CEBP-β/G-CSF/noncanonical NF-κB axis.
Article in Bioengineering & translational medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
An ischemic insult at optic nerve (ON) is followed by detrimental neuroinflammation that results in progressive and long-lasting retinal ganglion cell (RGC) death and vision loss. Icariin was reported to be a safe and effective natural anti-inflammatory drug. Herein, we evaluated the long-term therapeutic effects of a single intravitreal injection of poly(lactide-co-glycolide) PLGA-icariin in a rat model of anterior ischemic optic neuropathy (rAION). Treatment with PLGA microspheres of icariin preserved the visual function and RGC density for 1 month in the rAION model. In addition, ON edema and macrophage infiltration were inhibited by treating PLGA microspheres of icariin. We found that the binding complex of icariin and CCAAT enhancer binding protein beta (CEBP-β) significantly induced endogenous granulocyte colony-stimulating factor (G-CSF) expression to activate noncanonical nuclear factor kappa B (NF-κB) signaling pathway by promoting an alternative phosphorylation reaction of IKK-β. Activation of noncanonical NF-κB signaling pathway promoted the M2 microglia/macrophage polarization and AKT1 activation, which prevented neuroinflammation and RGC apoptosis after ON infarct. This study concluded that protective mechanism of icariin is a CEBP-β/G-CSF axis-induced noncanonical NF-κB activation, which provides the long-term neuroprotective effects via anti-inflammatory and antiapoptotic actions after ON ischemia.
