Abstract

Substance use disorders (SUDs) is characterized by the deregulation of motivational brain circuits and involves neuroadaptation processes that contribute to the transition from controlled to compulsive consumption of drugs of abuse. Such neuroadaptations are consolidated in long-term changes due to changes in gene expression regulation. These changes are regulated by the chromatin structure and epigenetic changes in the DNA and histone proteins that make up the chromatin. The epigenetic mechanisms control the space between the nucleosomes and the levels of their condensation allowing the access of the transcriptional machinery to the promoter of a specific gene. In recent decades, studies with animal models have shown that the use of drugs of abuse can trigger epigenetic changes in several brain regions important for the perpetuation of the addiction cycle. This chapter discusses neurobiological aspects and epigenetic mechanisms, such as DNA methylation and post-translational modifications of histones involved in SUDs.
