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

Microglia has been reported to be able to regulate the proliferation, differentiation and survival of adult neural stem/progenitor cells (NSPCs) by modulating the microenvironment, which results in different consequences of adult neurogenesis. However, whether the microglial activation is beneficial or harmful to NSPCs is still controversial because of the complexity and variability of microglial activation phenotypes. In this study, we systematically explored the activation phenotypes of IFN-γ- or IL-4-induced microglia at different time after stimulation, and investigated the effects of the secretome of different phenotype of microglia on the process of proliferation, differentiation and survival of NSPCs. Moreover, the possible molecular pathways of secretory influence on NSPCS were further explored using western blotting. The result showed that IFN-γ and IL-4 differently regulate microglial phenotypes, IL-4 induced a M2-like phenotype, while IFN-γ induced a M1-like phenotype. These phenotypes of microglia can only be maintained for 24 h after removal of IFN-γ or IL-4 intervention. The secretome from IFN-γ- or IL-4-induced microglia also had opposite effects on NSPCs proliferation, differentiation and survival. The secretome from the IL-4-treated microglia promoted NSPCs proliferation, survival and differentiation into neurons and oligodendrocytes, while factors secreted by the INF-γ-treated microglia stimulated the NSPCs differentiation into astrocyte, inhibited the neurogenesis and oligodendrogliogenesis, and induced NSPCs apoptosis. Furthermore, the PI3K-Akt pathway mediates the effects of the secretome from IFN-γ- or IL-4-induced microglia on NSPC proliferation, differentiation, and survival. In conclusion, our results suggested that the secretome of microglia induced by IL-4 of IFN-γ differently regulate proliferation, differentiation and survival of adult neural stem/progenitor cell by targeting the PI3K-Akt pathway. These findings will help further study the biological mechanism of microglia regulating neurogenesis, and provide a therapeutic strategy for neurological diseases by regulating microglial phenotypes to affect neurogenesis.
