Abstract:
:The 5-HT2A receptor is a target for hallucinogenic and non-hallucinogenic ligands that evoke unique behavioral, electrophysiological and molecular consequences. Here, we explored the differential effects of distinct 5-HT2A receptor ligands on signaling pathways downstream to the 5-HT2A receptor. The hallucinogenic 5-HT2A receptor agonist DOI evoked an enhanced signaling response compared to the non-hallucinogenic 5-HT2A receptor agonist lisuride in human/rat 5-HT2AR-EGFP receptor expressing HEK293 cell lines and cortical neuronal cultures. We noted higher levels of phospho-PLC, pPKC, pERK, pCaMKII, pCREB, as well as higher levels of IP3 and DAG production following 5-HT2A receptor stimulation with DOI. Our study reveals distinct signaling signatures, differing in magnitude and kinetics at the 5-HT2A receptor in response to DOI versus lisuride.
