Cancer Neuroscience: Linking Neuronal Plasticity with Brain Tumor Growth and Resistance
Neuronal plasticity, traditionally vital for brain function, is paradoxically hijacked by brain tumors like glioblastoma to fuel their growth, invasion, and resistance to therapy, redefining cancer as a 'neuro-oncological network disease'.
This emerging field reveals that tumor cells actively form functional synapses with neurons, exploiting neurotransmitter signaling and activity-dependent mechanisms to enhance proliferation and evade treatment. The tumor microenvironment, including glial cells, further reinforces this pathological ecosystem, necessitating multi-axis therapeutic strategies.
Redefining Brain Cancer: The Neuro-Oncological Paradigm Shift
This analysis highlights a critical pivot in cancer research: moving beyond tumor-intrinsic genomics to recognize the brain's dynamic role in tumor progression. By understanding how neuronal plasticity is co-opted, we unlock new avenues for precision diagnostics and multi-targeted therapies, promising a significant shift in patient outcomes.

LTP
Core Mechanism of Learning & Memory
Synaptic Remodeling
Normal neuronal plasticity involves structural and functional changes in synapses, supporting learning and memory. This is characterized by Long-Term Potentiation (LTP), the strengthening of synaptic connections after repeated stimulation, and Long-Term Depression (LTD), which weakens connections. These processes are crucial for adaptive brain function, but in tumor-driven plasticity, these same mechanisms are pathologically reprogrammed. The N-methyl-D-aspartate receptor (NMDAR) and AMPA receptor (AMPAR) play key roles in calcium influx, driving these changes. Dendritic spine dynamics, axon growth, and intrinsic excitability are all components of this intricate system, which tumors exploit for their own growth.
NLGN3
Key Glioma Mitogen
Neuroglioma Synapses & Excitatory Signaling
High-grade gliomas (HGGs) exploit neuronal plasticity via several mechanisms. Neuroligin-3 (NLGN3), released from neurons and glial precursors, activates the PI3K–mTOR pathway in glioma cells, promoting growth. Diffuse midline gliomas (DMGs) show dependency on GABAergic inputs, which depolarize tumor cells due to abnormal chloride regulation, accelerating proliferation. Hemispheric HGGs primarily rely on glutamatergic signaling through AMPA receptors. Tumor microtubules (TMs) also contribute to invasion and resistance, sharing characteristics with neural stem cells. The tumor microenvironment creates distinct niches like the perivascular niche (PVN) that use Notch Receptor 1 (NOTCH1) signaling to maintain stem-like properties and support resistance.

SLC7A11
Mediator of Chemo/Radioresistance
Synaptic Rewiring & GSC Support
Post-treatment, gliomas exhibit adaptive synaptic rewiring. Malignant cells form excitatory synapses with peritumoral neurons, leading to membrane depolarization and calcium signaling that promotes proliferation. Neuron-derived secreted proteins like NLGN3 and BDNF (Brain-Derived Neurotrophic Factor) act as paracrine mitogens, activating pathways like MAPK/PI3K/AKT. Extracellular glutamate, accumulated via SLC7A11/xCT, promotes hyperexcitability and protects tumor cells from oxidative stress, contributing to chemo/radioresistance. Glioma stem-like cells (GSCs) thrive in neuron-rich niches, leveraging neuronal activity for self-renewal and enhanced survival post-therapy.

Targeting Neuroglioma Synapses for Therapeutic Gain
Preclinical studies demonstrate that inhibiting ADAM10 (which cleaves NLGN3) significantly reduces tumor growth. Similarly, blocking AMPA-type glutamate receptors with agents like perampanel suppresses glioma proliferation. These interventions disrupt the critical neuron-glioma crosstalk that drives tumor expansion and resistance.
Impact: These strategies represent a paradigm shift, targeting the neuro-oncological network rather than just tumor cells, offering hope for overcoming current treatment limitations.

Pharmacological & Neuromodulation Approaches
Novel therapeutic strategies aim to disrupt neuron-tumor interactions. Pharmacological approaches include glutamate inhibitors (e.g., sulfasalazine), AMPA/NMDA receptor antagonists (e.g., perampanel), and GABA agonists to restore excitatory-inhibitory balance. Neuromodulation techniques like Transcranial Magnetic Stimulation (TMS), Deep Brain Stimulation (DBS), and optogenetics offer direct control over neuronal excitability. These methods are complemented by computational and AI approaches for modeling tumor-neuron networks and personalizing therapy.

|---|---|---|---|
| Sulfasalazine | xCT cystine-glutamate exchanger | Suppresses glutamate release | Preclinical + small pilot clinical studies |
| Perampanel | AMPA-type glutamate receptors | Reduces neuronal hyperactivity & glioma proliferation | Preclinical; ongoing clinical trials |
| GABAergic Agonists | GABA-A receptor complexes | Restores inhibitory signaling | Preclinical models only |
