Removing HDAC3 improves long-term memory problems caused by disrupting a neuron-specific gene regulator

Deleting HDAC3 can improve long-term memory and synaptic plasticity impairments caused by BAF53b mutation.

• Histone acetylation and nucleosome remodeling are both involved in long-term memory formation.
• Enhancing histone acetylation typically leads to improved long-term memory.
• Blocking the chromatin remodeling subunit BAF53b disrupts nucleosome remodeling and impairs memory.
• The deletion of HDAC3 may counteract the negative effects of BAF53b mutation on memory and synaptic function.
• There is a dynamic interplay between histone modification and nucleosome remodeling in memory regulation.
