Characterizing and Interrupting Microglia-Astrocyte Neuroinflammatory Amplification Loops

Microglia-derived IL-1α, TNF, and C1q activate neurotoxic A1 astrocytes, which in turn secrete complement factors feeding back to microglia. Breaking this loop is a therapeutic strategy, but the dominant axes vary by disease/stage and multiple redundant pathways limit single-target approaches.

Microglia-astrocyte crosstalk amplification loops in neurodegeneration

Microglia activate astrocytes via IL-1alpha/TNF/C1q, and reactive astrocytes feed back to microglia via complement/chemokines.
