Elevated immune response in the brain of autistic patients.

This study determined immune activities in the brain of ASD patients and matched normal subjects by examining cytokines in the brain tissue…. ASD patients displayed an increased innate and adaptive immune response through the Th1 pathway, suggesting that localized brain inflammation and autoimmune disorder may be involved in the pathogenesis of ASD.
