β-Endorphin Mediates Electroacupuncture-Induced Remyelination via Neural Stem Cell Lineage Modulation in Experimental Autoimmune Encephalomyelitis.
Article in CNS neuroscience & therapeutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
aimsEffective remyelination in multiple sclerosis (MS) requires both the proliferation of endogenous neural stem cells (NSCs) and their lineage-specific differentiation into oligodendrocyte progenitor cells (OPCs). This study aimed to investigate whether electroacupuncture (EA) promoted NSC proliferation and OPC differentiation via β-endorphin (β-EP)-mediated opioid signaling in a murine model of MS.
methodsExperimental autoimmune encephalomyelitis (EAE) was induced in C57BL/6 mice to model MS. EA stimulation was applied daily at the Zusanli (ST36) acupoint. NSC proliferation and OPC differentiation were assessed via immunofluorescence, flow cytometry (FCM), and RT-qPCR. β-EP expression and opioid receptor involvement were evaluated in the hypothalamus and subventricular zone (SVZ). Naloxone, a nonselective opioid receptor antagonist, was used to determine the role of opioid signaling in EA-induced effects.
resultsEA significantly enhanced NSC proliferation and increased the proportion of NSC-derived OPCs in the SVZ of EAE mice. EA treatment improved clinical score, reduced demyelination, and attenuated leukocyte infiltration of the central nervous system (CNS). Mechanistically, EA upregulated β-EP and its precursor pro-opiomelanocortin (POMC), along with opioid receptors μ-opioid receptor (MOR) and κ-opioid receptor (KOR) (encoded by Oprm1 and Oprk1, respectively). Naloxone administration abolished the beneficial effects of EA on NSC behavior and remyelination, confirming the involvement of opioid receptor-dependent β-EP signaling.
conclusionEA promotes remyelination in EAE mice by stimulating β-EP-mediated NSC proliferation and OPC differentiation. These findings reveal a novel neuroregenerative mechanism and support EA as a promising adjunctive strategy for demyelinating diseases such as MS.
