Autoantibodies in autism spectrum disorders (ASD)

Area of Science:

• Neuroimmunology
• Developmental Neuroscience
• Behavioral Science

Background:

• Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by social, communication, and behavioral deficits.
• The precise causes of ASD remain largely unknown, with current understanding pointing to a multifactorial etiology involving genetic, environmental, and immunological factors.
• Immune system dysregulation, particularly the presence of autoantibodies, is increasingly recognized as a potential contributing factor in ASD.

Purpose of the Study:

• To review existing literature on immune system anomalies and autoantibodies in individuals with ASD.
• To present findings from the authors' group regarding autoantibodies targeting neural antigens in ASD patients.
• To highlight the potential role of neuroinflammation and autoimmunity in the pathophysiology of ASD.

Main Methods:

• Literature review of studies investigating immune markers in ASD.
• Presentation of original research data on autoantibody prevalence in ASD cohorts.
• Analysis of autoantibodies directed against specific neural antigens.

Main Results:

• Various immune system anomalies have been reported in subjects diagnosed with ASD.
• Autoantibodies targeting neural antigens are present in a subset of individuals with ASD.
• The authors' research group has identified specific autoantibodies linked to ASD.

Conclusions:

• Autoantibodies against neural antigens represent a significant area of investigation in ASD etiology.
• Immune system dysfunction may play a crucial role in the development or manifestation of ASD.
• Further research into neuroautoimmunity could lead to novel diagnostic or therapeutic strategies for ASD.
