Abstract

Histone deacetylase 3 (HDAC3) is a critical regulator of gene expression, influencing a variety of cellular processes in the central nervous system. As such, dysfunction of this enzyme may serve as a key driver in the pathophysiology of various neuropsychiatric disorders and neurodegenerative diseases. HDAC3 plays a crucial role in regulating neuroinflammation, and is now widely recognized as a major contributor to neurological conditions, as well as in promoting neuroprotective recovery following brain injury, hemorrhage and stroke. Emerging evidence suggests that pharmacological inhibition of HDAC3 can mitigate behavioral and neuroimmune deficits in various brain diseases and disorders, offering a promising therapeutic strategy. Understanding HDAC3 in the healthy brain lays the necessary foundation to define and resolve its dysfunction in a disease state. This review explores the mechanisms of HDAC3 in various cell types and its involvement in disease pathology, emphasizing the potential of HDAC3 inhibition to address neuroimmune, gene expression and behavioral deficits in a range of neurodegenerative and neuropsychiatric conditions.
