Introduction Neuroinflammation-responsive neurons are neurons that actively respond to inflammatory signals in the central nervous system. These cells play a critical role in neurodegeneration, as chronic neuroinflammation is a hallmark of Alzheimer's disease, Parkinson's disease, ALS, and other neurodegenerative disorders. Understanding neuronal responses to inflammation is crucial for developing therapeutic interventions[@glass2010].
