Autism spectrum disorder ASD is a neurodevelopmental disorder characterized by impairments in communication verbal and nonverbal, social interactions, and stereotyped behaviorsinterests. The etiology of ASD is not well understood, though it likely involves both genetic and environmental factors. Immune system dysfunction has been reported in ASD in many studies. Systemic immunologic alterations in autistic individuals often have been associated with autoimmunity in particular, the generation of antibodies reactive against brain and CNS proteins. The goal of this grant proposal is to identify serum antibody biomarkers for ASD using a novel combinatorial peptoid library that has been successful for the identification of antibody biomarkers for Alzheimer s disease. An ASD blood biomarker would be very useful for early identification and targeted therapeutic intervention. During Year-1 of the grant we have 1 collected serum samples from additional male typically developing TD and unaffected sibling US controls 2 collected serum samples from additional female TD and US controls 3 made peptoid libraries and 4 screened libraries for peptoids using pooled serum samples from male ASD, and male TD controls.
