Integration of „environmental“ information in the neuronal epigenome

The inhibitory actions of the heterogeneous collection of GABAergic interneurons tremendously influence cortical information processing, which is reflected by diseases like autism, epilepsy and schizophrenia that involve defects in cortical inhibition. Apart from the regulation of physiological processes like synaptic transmission, proper interneuron function also relies on their correct development. Hence, decrypting regulatory networks that direct proper cortical interneuron development as well as adult functionality is of great interest, as this helps to identify critical events implicated in the etiology of the aforementioned diseases. Thereby, extrinsic factors modulate these processes and act on cell- and stage-specific transcriptional programs. Herein, epigenetic mechanisms of gene regulation, like DNA methylation executed by DNA methyltransferases (DNMTs), histone modifications and non-coding RNAs, call increasing attention in integrating “environmental information” in our genome and sculpting physiological processes in the brain relevant for human mental health. Several studies associate altered expression levels and function of the DNA methyltransferase 1 (DNMT1) in subsets of embryonic and adult cortical interneurons in patients diagnosed with schizophrenia. Although accumulating evidence supports the relevance of epigenetic signatures for instructing cell type-specific development, only very little is known about their functional implications in discrete developmental processes and in subtype-specific maturation of cortical interneurons. Similarly, little is known about the role of DNMT1 in regulating adult interneurons functionality. This talk will provide an overview about newly identified and roles DNMT1 has in orchestrating cortical interneuron development and adult function. Further, this talk will report about the implications of lncRNAs in mediating site-specific DNA methylation in response to discrete external stimuli.
