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

backgroundAberrant microglial activation and impaired adult hippocampal neurogenesis play critical roles in the pathogenesis of depression. Although electroacupuncture (EA) has demonstrated clinical antidepressant efficacy, the underlying mechanisms by which it modulates microglial activity and promotes neurogenesis remain unclear.

methodsMale C57BL/6 J mice were subjected to chronic unpredictable mild stress (CUMS) for three weeks. Following this period, the mice were divided into groups receiving either EA at the Yintang (GV29) and Baihui (GV20) acupoints, imipramine (IMI) as a positive control, or no treatment (vehicle control) for an additional 3 weeks. To evaluate depressive-like behaviors, we conducted the sucrose preference test, forced swimming test, and tail suspension test. Anxiety-like behaviors were assessed using the open field test and elevated plus maze. We employed immunofluorescence, Golgi staining, Western blotting, and real-time quantitative PCR (qRT-PCR) to elucidate the effects of EA on microglia-driven hippocampal neurogenesis and BDNF signaling. Notably, loss-of-function experiments utilizing PLX5622 for microglial ablation and ANA-12 for TrkB blockade demonstrated the necessity of both microglia and BDNF signaling for the therapeutic efficacy of EA.

resultsEA treatment significantly alleviated CUMS-induced anxiodepressive behaviors. This behavioral recovery was associated with a phenotypic shift in microglia towards a pro-neurogenic state in the hippocampus. Importantly, microglia were essential for the therapeutic effects of EA, as evidenced by their ablation with PLX5622. Furthermore, EA enhanced neurogenesis by orchestrating a multi-step augmentation of BDNF signaling, which involved PKA activation, subsequent release from MeCP2-mediated transcriptional repression, and ultimately increased maturation of BDNF.

conclusionsOur findings demonstrate that EA exerts antidepressant effects by promoting a pro-neurogenic transformation of microglia. Mechanistically, these microglia enhance BDNF function via the PKA/MeCP2/BDNF pathway, thereby facilitating hippocampal neurogenesis and restoring synaptic plasticity, which collectively alleviate depressive symptoms.
