Retrotransposon: an insight into neurological disorders from perspectives of neurodevelopment and aging

Abstract

Abstract Neurological disorders present considerable challenges in diagnosis and treatment due to their complex and diverse etiology. Retrotransposons are a type of mobile genetic element that are increasingly revealed to play a role in these diseases. This review provides a detailed overview of recent developments in the study of retrotransposons in neurodevelopment, neuroaging, and neurological diseases. Retrotransposons, including long interspersed nuclear elements-1, Alu, SINE-VNTR-Alu, and endogenous retrovirus, play important regulatory roles in the development and aging of the nervous system. They have also been implicated in the pathological processes of several neurological diseases, including Alzheimer's disease, X-linked dystonia-parkinsonism, amyotrophic lateral sclerosis, autism spectrum disorder, and schizophrenia. Retrotransposons provide a new perspective for understanding the molecular mechanisms underlying neurological diseases and provide insights into diagnostic and therapeutic strategies of these diseases.
