Neuro-glioma activity-dependent growth mechanisms: an actionable circuit from NLGN3-ADAM10 to AMPA synapses. (PubMed, Transl Cancer Res)
Neuronal and oligodendroglial firing activates ADAM10, generating soluble NLGN3 (sNLGN3) that reprograms glioma cells toward a highly neural, synapse-competent state through kinase, epigenetic and mechanosensory pathways, including LYN proto-oncogene, Src family tyrosine kinase (LYN), phosphoinositide 3-kinase (PI3K)-mechanistic target of rapamycin (mTOR) and chondroitin sulfate proteoglycan 4 (CSPG4)-Piezo-type mechanosensitive ion channel component 1 (PIEZO1) signaling...On this basis, we outline an "actionable circuit" spanning neuronal activity, NLGN3-ADAM10 shedding, intracellular signaling, synaptic integration and network remodeling, and we organize emerging pharmacologic and device-based strategies into a circuit-breaking framework that includes activity dampening, inhibition of NLGN3 shedding, blockade of downstream signaling and AMPA synapses, and network-level modulation. Finally, we highlight key translational challenges and opportunities in target selectivity, brain delivery, biomarker development and adaptive trial design, arguing that multidimensional, circuit-informed interventions may complement standard surgery, radiochemotherapy and molecular targeting in selected patients with activity-driven glioma.
