Alterations in CB1R expression occur selectively and progressively and have been linked to numerous metabolic disorders, cancer, and neurodegenerative diseases. Recent studies have begun to unveil the transcriptional and epigenetic mechanisms regulating CB1R expression, involving inflammatory transcription factors, nuclear receptors, metabolic regulators, redox-sensitive pathways, hormone-responsive factors, as well as chromatin remodeling marks and promoter methylation. These modulatory programs collectively shape CB1R abundance and availability and may critically influence the efficacy and safety of cannabinoid-based therapies.
