Abstract: Depression involves plasticity of brain reward neurons, although the mechanisms and behavioral relevance are unknown. Transcriptional profiling of nucleus accumbens (NAc) for RhoGTPase related genes, known regulators of synaptic structure, following chronic social defeat stress, revealed a long-term reduction in Rac1 transcription. This was marked by a repressive chromatin state surrounding its proximal promoter. Inhibition of class 1 HDACs with MS-275 rescued both decreased Rac1 transcription and social avoid…
