Investigating Serine Proteases in Autism Spectrum Disorder

Research from the Department of Medical Biochemistry in Turkey has unveiled new insights into the role of serine proteases in autism spectrum disorder (ASD). The study focused on 44 children with ASD and 43 age- and sex-matched controls, assessing symptom severity and specific behavioral domains. The results suggest that peripheral biochemical markers may aid in identifying ASD subtypes and guiding personalized therapeutic strategies.

Key Takeaways:

  • The study aimed to elucidate the potential role of serine proteases and their associated regulatory molecules in the etiopathogenesis of ASD.
  • Behavioral assessments were conducted using the Childhood Autism Rating Scale (CARS), the Autism Behavior Checklist (ABC), and the Repetitive Behavior Scale-Revised, Turkish Version (RBS-R-TV).
  • Serum concentrations of motopsin, agrin, C-terminal agrin fragment (CAF), tissue plasminogen activator (tPA), neuroserpin, and plasminogen activator inhibitor-1 (PAI-1) were determined using enzyme-linked immunosorbent assay (ELISA).
  • Serum levels of all analyzed molecules were significantly reduced in the ASD group compared to controls.
  • The observed domain-specific associations support the hypothesis that ASD comprises heterogeneous neurodevelopmental trajectories.
  • Peripheral biochemical markers may aid in identifying ASD subtypes and guiding personalized therapeutic strategies.
  • The study has been peer-reviewed and published in the Journal of Molecular Neuroscience.
  • Researchers identified additional authors including Ozlem Dogan, Fatma Zehra Kirsan, and Didem Behice Oztop.
  • The Journal of Molecular Neuroscience is published by SpringerNature and can be contacted at Springernature, Campus, 4 Crinan St, London, N1 9XW, England.

Statistics:

  • 44 children with ASD and 43 age- and sex-matched controls were included in the study (p < 0.05).
  • Serum levels of all analyzed molecules were significantly reduced in the ASD group compared to controls (p < 0.05).
  • The observed domain-specific associations support the hypothesis that ASD comprises heterogeneous neurodevelopmental trajectories.
  • The study aimed to elucidate the potential role of serine proteases and their associated regulatory molecules in the etiopathogenesis of ASD (2025, Journal of Molecular Neuroscience).
