Systems Biology Approaches as a Tool in Understanding Neurodevelopmental Disorders: Some Case Studies

Systems biology has emerged as a powerful approach in neurology and neurosciences, offering novel insights into the complex mechanisms underlying various neurological diseases. The intricate nature of the nervous system necessitates a comprehensive approach to comprehending neurological disorders. Systems biology integrates multidisciplinary techniques, including genomics, proteomics, metabolomics, and computational modelling, to unravel the intricate networks of molecular interactions within neurons, glia, and other central and peripheral nervous system cells. Recently, systems biology has made significant strides in elucidating the pathogenesis of neurodegenerative disorders like Parkinson’s disease, Alzheimer’s disease, and amyotrophic lateral sclerosis. Researchers have identified key molecular players and dysregulated pathways by integrating large-scale omics data with advanced computational methods, shedding light on disease progression, and potential therapeutic targets. Furthermore, systems biology has improved our knowledge of neurodevelopmental disorders, which includes disorders in the autism spectrum and intellectual disabilities. Researchers have revealed disrupted molecular pathways underlying these conditions by deciphering gene regulatory networks and functional modules, offering new avenues for targeted interventions, and personalized medicine. Moreover, systems biology has facilitated the exploration of complex brain functions, including learning, memory, and behaviour. Integration of multi-level data, such as transcriptomics and neuroimaging, has unravelled the intricate interplay between genes, neural circuits, and cognitive processes. This book chapter presents a comprehensive overview of the usage of systems biology in neurology and neurosciences. It demonstrates how the integration of high-throughput technologies, computational modelling, and multi-omics data has widened our understanding of neurological diseases, paving the way for personalized medicine and improved patient outcomes. The chapter also highlights the potential for further advancements in the field and the importance of interdisciplinary collaborations to tackle the difficulties of studying complex neurological systems.
