The aim of the study was to analyze cytokine profiles in neonatal dried blood samples (n-DBSS) retrieved from The Danish Newborn Screening Biobank of children developing Autism Spectrum Disorders (ASD) later in life and controls. Samples of 359 ASD cases and 741 controls were analyzed using Luminex xMAP technology and clinical data were retrieved from nationwide registers. Findings showed that children developing ASD were more likely to have decreased levels of both T helper-1(Th-1)-like cytokines (i.e. IFN-γ) and Th-2like cytokines (i.e. IL-4, IL-10) which may suggest a depressed or hypoactive immune cell activity during neonatal period in ASD.
