Core Viewpoint - The study reveals the complex interactions between neurons and glioblastoma cells, highlighting long-range cholinergic input as a significant factor in glioblastoma progression, providing new insights for cancer neuroscience research [4][8]. Group 1: Research Findings - The research team created a comprehensive brain connectivity map of glioblastoma (GBM) cells, demonstrating the influence of long-range cholinergic neurons on GBM progression [4][9]. - Local inputs are primarily glutamatergic, while long-distance connections exhibit diverse neurotransmitter characteristics, with cholinergic projections from the basal forebrain being a conserved input across different regions [7][9]. - The study identifies that acetylcholine release through muscarinic receptor CHRM3 promotes GBM growth in a circuit-specific manner, and blocking both acetylcholine and glutamate pathways results in an additive anti-tumor effect [10] [9]. Group 2: Implications for Treatment - Anticholinergic drug scopolamine inhibits GBM growth, while acetylcholinesterase inhibitor donepezil exacerbates the condition, indicating the potential for targeted therapies based on neurotransmitter signaling [4][7]. - The findings suggest that long-range neural regulatory pathways could serve as promising therapeutic targets for glioblastoma treatment [8].
