Unraveling the role of neuregulin-mediated astrocytes-OPCs axis in the pathogenesis of age-related macular degeneration and Parkinson's disease.
Article in Scientific reports, 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
Age-related macular degeneration (AMD) and Parkinson's disease (PD) are prevalent and debilitating conditions that lead to irreversible blindness and dyskinesia, respectively. Emerging evidences imply that retinal abnormalities may serve as early indicators for monitoring PD. This study endeavors to explore the complex interactions and focus on their shared molecular and pathological mechanisms. We employed a comprehensive approach by integrating single-cell RNA sequencing (scRNA-seq) datasets, obtained from dry AMD retinas and PD brain tissues, along with Weighted Gene Co-expression Network Analysis (WGCNA)-related computational analysis. Gene Set Enrichment Analysis (GSEA) was conducted to analyze PD-related genes within retinal ganglion cells in dry AMD. Cell-cell chat was utilized to predict intercellular communication and signaling pathways. Module eigengenes (MEs) were calculated to identify specific gene modules. Dysregulation of PALLD, FYN and ZMZ1 may lead to cell structural abnormalities, impaired mitochondrial functions, and increased susceptibility to neuroinflammation, contributing to the AMD and PD progression. Additionally, this study highlighted an astrocyte-oligodendrocyte precursor cell (OPCs) signaling axis mediated by Neuregulin (NRG), which is hypothesized to influence neuroinflammatory processes characteristic of dry AMD and PD pathogenesis. Notably, ME-salmon module associated with gene dysregulation exhibited a strong positive correlation with the ME-blue module, linked to neurodegenerative impairment, and the ME-yellow module, related to mitochondrial dysfunction. The comprehensive investigation on astrocytes-OPCs signaling axis, and the NRG signaling pathway advances our understanding of the intricate biological processes underpinning AMD and PD. This research underscores the critical importance about exploring glial-related cell interactions, providing valuable insights into potential novel therapeutic approaches for these complex diseases.
