Epigenetics and Neuroinflammation Associated With Neurodevelopmental Disorders: A Microglial Perspective

Area of Science:

• Neuroscience
• Developmental Biology
• Epigenetics

Background:

• Neuroinflammation is implicated in neurodevelopmental disorders, including autism spectrum disorders, fetal alcohol syndrome, and cerebral palsy.
• Epigenetic modifications, such as DNA methylation and microRNA (miRNA) expression, are increasingly recognized as key players in neuroinflammation.
• The interplay between genetic and environmental factors can influence epigenetic regulation and neuroinflammation, potentially leading to developmental disorders.

Purpose of the Study:

• To review the role of epigenetic dysregulation in microglia-mediated neuroinflammation.
• To compare findings from mammalian and zebrafish models regarding epigenetics and neuroinflammation.
• To highlight the connection between epigenetic alterations, neuroinflammation, and neurodevelopmental disorders.

Main Methods:

• Literature review focusing on epigenetic mechanisms (DNA methylation, miRNA) in microglia.
• Comparative analysis of studies in mammals and zebrafish.
• Synthesis of evidence linking epigenetic dysregulation to neuroinflammation and neurodevelopmental outcomes.

Main Results:

• Evidence suggests that altered DNA methylation and miRNA profiles in microglia are associated with neuroinflammation.
• Epigenetic dysregulation in microglia can be influenced by both genetic predisposition and environmental exposures.
• Both mammalian and zebrafish models provide insights into the conserved mechanisms of microglia-mediated neuroinflammation.

Conclusions:

• Epigenetic dysregulation in microglia is a significant factor contributing to neuroinflammation and subsequent neurodevelopmental disorders.
• Understanding these epigenetic mechanisms is crucial for developing targeted interventions.
• Comparative studies across species like mammals and zebrafish can elucidate fundamental pathways involved in neurodevelopmental disorders.
