Reelin and its complex involvement in brain development and function

Reelin is a neuroprotein with crucial role during neurodevelopment and also in postnatal period. It regulates neuronal migration and positioning in developing neocortex and cerebellar cortex. Postnatally it participates in regulation of dendritic and axonal growth, synaptogenesis, neurotransmission and it contribute to synaptic plasticity necessary for learning and memory functions. Role of Reelin seems to be rather complex, profound research gradually uncovers its further functions. Deficits of Reelin were detected in neuropsychiatric disorders such as schizophrenia, bipolar disorder and autism. Pathogenesis of these disorders is far from being clearly understood. Reelin contribution to these diseases seems to be vital, since genetic variants of Reelin were associated with these diseases and often influence symptom severity. Reelin is a promising candidate molecule with potential future use in diagnostics and therapy, however further detailed research is essential.
