Abstract
Emerging preclinical autism research has shown the therapeutic promise of pharmacological inhibitors for epigenetic enzymes, such as histone deacetylases (HDAC), euchromatic histone methyltransferases (EHMT), and lysine-specific histone demethylase 1A (LSD1). These interventions restore gene expression, synaptic function, and behavioral performance in autism models, highlighting a new strategy for autism treatment.
