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

Neuroinflammation is a key pathogenic factor for neurodegenerative diseases. Mesenchymal stem cell (MSC) transplantation, as a potential strategy for regulating neuroinflammation, has received extensive attention. Our previous research revealed that compared with ordinary MSC, MSC pretreated with tanshinone IIA (TIIA), referred to as TIIA-MSC, exhibited superior anti-neuroinflammatory activity, but the mechanism of action remains unclear. To clarify the underlying mechanism, this study integrated in vitro and in vivo experiments and evaluated the therapeutic effect of TIIA-MSC in a triple-transgenic Alzheimer's disease mouse model (3×Tg-AD mice) and explored its mechanism of action in a lipopolysaccharide (LPS)-induced BV2 microglial cell inflammation model. The results showed that TIIA-MSC could significantly improve the cognitive function of 3×Tg-AD mice, increase brain glucose metabolism levels, promote the recovery of synaptic and mitochondrial structures, and effectively alleviate neuroinflammatory responses. In vitro experiments further verified the superior inhibitory effect of TIIA-MSC on microglial cell activation and proinflammatory factor release. Mechanistic studies have indicated that the triggering receptor expressed on myeloid cells 2 (TREM2) is the key molecule that mediates this process. The knockdown of TREM2 expression significantly weakened the anti-inflammatory effect of TIIA-MSC, suggesting that TREM2 plays a central role in this process. Further analysis revealed that by activating the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway downstream of TREM2, TIIA-MSC may promote the transformation of the functional state of microglia from mainly proinflammatory to having neuroprotective and repair properties. This study systematically revealed the molecular mechanism by which TIIA-MSC regulate microglial cell phenotypic transformation through the TREM2/PI3K/Akt pathway and exert anti-neuroinflammatory effects, providing new ideas and an experimental basis for expanding the application of MSC in the treatment of neurodegenerative diseases.
