Beautiful work & insightful BlueSkytorial by @venkataramanilab.bsky.social. Using modified rabies viruses, they show that glioblastoma tumor cells rapidly make connections with neurons & these interactions represent targetable vulnerabilities that could open therapeutic avenues for brain cancers.

Characterizing and targeting glioblastoma neuron-tumor networks with retrograde tracing
Rapid integration of glioblastoma into neuronal circuits promotes glioblastoma invasion and growth, as shown by rabies-based retrograde tracing. Targeting of neuron-tumor networks with pharmacological or rabies-mediated disconnection offers therapeutic potential.

💊 This led us to combine radiation with drugs that reduce neuronal activity. The combination proved more effective at treating tumors than either approach alone. 10/15

🧬 Using single-cell RNA sequencing and a functional neurotransmitter receptor screening, we found tumor cells express receptors for multiple neurotransmitters. This allows them to receive signals from many different types of neurons. 7/15

🌐 These weren't just local connections. The tumor cells established networks with neurons across different brain regions and even between hemispheres across large distances, showing remarkable integration. 5/15

⚡️ The timeline surprised us: Tumor cells formed functional connections with neurons very quickly with neurons within hours in culture and just days in the brain- much earlier than previously known and expected. 4/15

🔬 Our approach used the infection of tumor cells with a modified rabies virus that can only jump once to a directly connected neuron. When a neuron connects to a tumor cell, it lights up, creating a precise map of their connectome. 3/15

🧪 How do brain tumors communicate with neurons? We developed a tracing system using modified rabies viruses to map these connections across the entire brain, revealing unexpected complexity. 2/15
