Summary

Changes in gene expression in the brain may underlie cognitive deficits inherent to neuropsychiatric and neurodegenerative disease. However, the mechanisms that underlie pathological alterations in the brain transcriptome are little understood. There is now accumulating evidence that altered chromatin plasticity and histone acetylation is involved in the pathogenesis of brain diseases. Histone deacetylase (HDAC) inhibitors exhibit neuroprotective and neuroregenerative properties and thus the targeting of HDACs appears to be a promising therapeutic strategy for the treatment of brain diseases. This article summarizes the latest results of the emerging field.
