When the Brain's Armor Crumbles: How Cerebellar Nets Trigger Autism Social Deficits Through ARNT2
Kanazawa University researchers trace autism social deficits to a precise mechanism: perineuronal nets in the deep cerebellar nuclei degrade across both environmental (VPA) and genetic (Chd8) models, triggering ARNT2 transcription factor surges that silence cerebellar output neurons and disconnect midbrain-thalamus social circuits — with ARNT2 suppression alone fully rescuing behavior.
