This review examines the intricate association between maternal immune activation (MIA) and autism spectrum disorder (ASD), emphasizing impact of infections during pregnancy. Epidemiological studies link viral bacterial to an elevated risk ASD, revealing complex interplay environmental factors neurodevelopmental outcomes. Immunological mechanisms, including cytokine dysregulation neuroinflammation, involve key players such as interleukin-6 tumor necrosis factor-alpha, influencing fetal brain development ASD risk. Genetic interactions contribute individual susceptibility, with specific variants MIA's on Epigenetic modifications provide a molecular exposures, MIA, enduring changes. Recognizing critical periods neurodevelopment susceptible MIA is crucial. Long-term highlight consequences behavior cognition into childhood adolescence. Exploring potential therapeutic interventions, immunomodulatory strategies pregnancy, offers hope for mitigating Despite progress, knowledge gaps persist, motivating future research guided by emerging technologies interdisciplinary approaches unravel MIA-ASD relationship.

Abstract Prenatal exposure to heightened maternal inflammation has been associated with adverse neurodevelopmental outcomes, including atypical brain maturation and psychiatric illness. In mothers experiencing socioeconomic disadvantage, immune activation can be a product of the chronic stress inherent such environmental hardship. While growing preclinical clinical evidence shown links between altered neonatal development increased inflammatory states in utero, potential mechanism by which disadvantage differentially impacts neural-immune crosstalk remains unclear. current study, we investigated associations gestational inflammation, white matter microstructure 320 mother-infant dyads over-sampled for poverty. We analyzed serum levels four cytokines (IL-6, IL-8, IL-10, TNF-α) over course pregnancy relation offspring disadvantage. Higher average IL-6 was very low status (SES; INR < 200% poverty line) lower corticospinal fractional anisotropy (FA) uncinate axial diffusivity (AD). No other cytokine SES.

Autism spectrum disorder (ASD) affects 1 in 36 people and is more often diagnosed males than females. Core features of ASD are impaired social interactions, repetitive behaviors deficits verbal communication. a highly heterogeneous heritable disorder, yet its underlying genetic causes account only for up to 80% the cases. Hence, subset cases could be influenced by environmental risk factors. Maternal immune activation (MIA) response inflammation during pregnancy, which can lead increased inflammatory signals fetus.
