Summary
Elevated levels of certain cytokines, including IL-34 and IL-10, were observed in children with autism spectrum disorder (ASD). These cytokine differences may indicate underlying autism pathophysiology but did not correlate with symptom severity.
Area of Science:
- Immunology
- Neuroscience
- Genetics
Background:
- Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with increasing prevalence.
- The role of immune dysregulation, particularly involving cytokines, is an emerging area of research in ASD.
- Microglia-regulating and T-helper cytokines are implicated in neuroinflammation and immune responses.
Purpose of the Study:
- To compare serum levels of IL-34, CSF-1, and T-helper cytokines (IL-12, IFN-γ, IL-4, IL-10, TGF-β, IL-17, IL-23) between children with ASD and healthy controls.
- To explore the relationship between these cytokine levels and the severity of autism symptoms as assessed by the Childhood Autism Rating Scale (CARS).
- To evaluate the diagnostic potential of these cytokines in distinguishing individuals with ASD.
Main Methods:
- Serum samples were collected from 42 children diagnosed with ASD and 40 healthy controls.
- Cytokine concentrations were quantified using the Enzyme-Linked Immunosorbent Assay (ELISA) method.
- Autism symptom severity was measured using the Childhood Autism Rating Scale (CARS).
- Receiver Operating Characteristic (ROC) curve analysis was employed to assess discriminative power.
Main Results:
- Serum levels of IL-34, CSF-1, IFN-γ, IL-4, IL-10, and IL-17 were significantly elevated in the ASD group compared to controls (p < 0.05).
- These elevated cytokines demonstrated significant power in distinguishing individuals with ASD.
- Interleukin-10 (IL-10) exhibited the highest discriminative ability (AUC = 0.743, p < 0.001).
- No significant correlations were found between the measured cytokine levels and autism severity scores.
Conclusions:
- The study identified elevated serum levels of IL-34, CSF-1, IFN-γ, IL-4, IL-10, and IL-17 in children with ASD.
- These cytokine alterations suggest potential involvement in the pathophysiology of autism.
- Further research with larger sample sizes and longitudinal designs is needed to confirm these findings and explore clinical utility.

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
