Epigenetic-based therapies in the preclinical and clinical treatment of Huntington's disease.

The study of epigenetics is providing novel insights about the functional and developmental complexity of the nervous system. In neuropathology, therapies aimed at correcting epigenetic dysregulation have been extensively documented in a large variety of models for neurodegenerative, neurodevelopmental and psychiatric disorders. Taking the treatment of Huntington's disease as a paradigm for the study of these ameliorative strategies, this review updates the main conclusions derived from the use of epigenetic drugs at the preclinical and clinical stages, including actions beyond epigenetics.
