Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairments in communication skills and social behaviors. Several studies have suggested that neuroimmune dysfunction plays a significant role in the pathogenesis of ASD; however, its exact etiology is unknown. Interleukin-16 (IL-16), a chemoattractant, is associated with various inflammatory processes. However, its role in children with ASD is unclear. This study aimed to investigate whether IL-16 expression is associated with immune dysfunction in children with ASD. We examined IL-16 expression in CD4, CD8, CD14, CCR3, and CXCR7 cells in typically developing (TD) controls and children with ASD using flow cytometry in peripheral blood mononuclear cells (PBMCs). We also investigated the expression of IL-1βIL-16, IL-6IL-16, and TNF-αIL-16 in TD controls and children with ASD. We further explored IL-16 mRNA and protein expression using RT-PCR and western blotting. CD4IL-16, CD8IL-16, CD14IL-16, CCR3IL-16, and CXCR7IL-16 cells increased significantly in children with ASD compared with TD controls. We also showed that expression of IL-1βIL-16, IL-6IL-16, and TNF-αIL-16 was elevated in children with ASD compared with TD controls. Moreover, IL-16 mRNA and protein expression was significantly induced in children with ASD compared with TD controls. These results suggest that IL-16 expression could play an essential role in immune alteration in children with ASD.

Background: Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder lacking objective biomarkers for early diagnosis. DNA methylation is a promising epigenetic marker, and machine learning offers a data-driven classification approach. However, few studies have examined whole-blood, genome-wide DNA methylation profiles for ASD diagnosis in school-aged children.

Autism spectrum disorder (ASD) is a neurodevelopmental syndrome that impacts two main areas: social communication and restrictive or repetitive behaviors. Other symptoms and comorbidities may be manifested, according to the different clinical presentations and severity levels. ASD diagnosis can be performed by two years of age; however, certain diagnostic challenges may lead to a late diagnosis and significant intervention delay.

Background & Objectives: The global rise in autism spectrum disorder (ASD) has highlighted the burden on healthcare systems and the significant impact on affected families. This study explored caregivers' perspectives on the healthcare experiences of children with ASD and the related challenges faced by families in Ras Al Khaimah, UAE.
Methods: A descriptive, cross-sectional study was conducted among caregivers of 38 children with confirmed ASD attending two autism centers.

Introduction: Absence of language development is a condition encountered across a large range of neurodevelopmental disorders, including a significant proportion of children with autism spectrum disorder. The neurobiological underpinnings of non-verbal ASD (nvASD) remain poorly understood.
Methods: This study employed multimodal MRI to investigate white matter (WM) microstructural abnormalities in nvASD, focusing on language-related pathways.

Parents of children with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) face unique challenges that may significantly increase stress levels, potentially impacting the emotional well-being of the entire family. In Mexico, limited research has examined the association between parental stress and coping strategies among families with children with developmental disabilities. This study aimed to compare stress levels and coping strategies among parents of children with ASD, ADHD, and neurotypical developing (NTD) children, as well as to analyze differences in coping styles across these groups.
