How serotonin-related brain signals in psychedelic drugs differ between sexes

Updated

Abstract

Sex and endocrine state may modulate responses to classic serotonergic psychedelics through various serotonergic mechanisms.

  • Classic psychedelics primarily act by activating the 5-HT2A receptor.
  • Therapeutic effects of these compounds can vary significantly based on biological sex.
  • Existing studies often overlook sex-by-treatment effects, limiting understanding of variability.
  • Sex and endocrine state may influence serotonin clearance and signaling pathways.
  • There is a need for more sex-informed research in both preclinical and clinical settings.
