Description
Astrocytes are support cells in the brain that change shape and behavior when the brain is inflamed or hurt, a state called reactivity. Shane Liddelow asks in 2025 what those reactive cells truly do, and whether the same states show up across diseases as unlike as Alzheimer's and brain cancer. He draws on gene, protein, and lipid studies in rodents, human grown cells, and mice.
Some reactive states first mapped in injury and dementia also appear in brains carrying tumors, he reports, and there they can feed tumor growth and spread. Other states seem to guard tissue, forming borders around damage. Because the same states recur across diseases, lessons from one may guide treatments for another. Liddelow argues that aiming drugs at reactivity is a shared opening worth testing.
