Microglia/macrophage polarization regulates spontaneous remyelination in intermittent cuprizone model of demyelination.

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
Central nervous system (CNS) lesions can repeatedly be de-and remyelinated during demyelinating diseases such as multiple sclerosis (MS). Here, we designed an intermittent demyelination model by 0.3 % Cuprizone feeding in C57/BL6 mice followed by two weeks recovery. Histochemical staining of luxol fast blue (LFB) was used for study of remyelination, detection of glial and endothelial cells was performed by immunohistochemistry staining for the following antibodies: anti Olig2 for oligodendrocyte progenitor cells, anti APC for mature oligodendrocytes, anti GFAP for astrocytes, and anti Iba-1 for microglia/macrophages, anti iNOS for M1 microglia/macrophage phenotype, anti TREM-2 for M2 microglia/macrophage phenotype and anti CD31 for endothelial cells. Also, real-time polymerase chain reaction was performed for assessment of the expression of the targeted genes. LFB staining results showed enhanced remyelination in the intermittent cuprizone (INTRCPZ) group, which was accompanied by improved motor function, increased mature oligodendrocyte cells, and reduction of astrogliosis and microgliosis. Moreover, switching from M1 to M2 polarity increased in the INTRCPZ group that was in association with downregulation of pro-inflammatory and upregulation of anti-inflammatory genes. Finally, evaluation of microvascular changes revealed a remarkable decrease in the endothelial cells in the cuprizone (CPZ) group which recovered in the INTERCPZ group. The outcomes demonstrate enhanced myelin content during recovery in the intermittent demyelination model which is in association with reshaping macrophage polarity and modification of glial and endothelial cells.
