A 2026 study in Frontiers in Cellular Neuroscience looked at astrocytes, the brain’s support cells. When researchers activated a specific immune signal called TLR3 on astrocytes in Parkinson’s models, the dopamine pathway was better protected. Why this matters 👇 🧠 Astrocytes released growth and survival signals 🧠 Fewer dopamine neuron
