Role of Mast Cells and Neuroinflammation in Neuropsychiatric Disorders of the Developmental Period

Mast cells can release different kinds of molecules as a response to different stimuli, particularly proinflammatory mediators that contribute to neuroinflammation. The enrichment of mast cells in specific areas of the nervous system and gastrointestinal tract, together with their degranulation, histamine and neuropeptide secretion, such as substance P, and mast cell–microglia interactions, may promote neuroinflammatory signaling in neurological and psychiatric disorders during childhood and adolescence. The aim of this review is to explore the mast cell-related molecular aspects of the main neuropsychiatric disorders of the developmental period, such as ADHD, autism spectrum disorder, and epilepsy, as well as anxiety and depression. The translational analysis of molecular pathways and the relationships involved may contribute to the development of innovative and targeted therapeutic approaches.
