Immunomodulation: Systemic Anti-Inflammatory Pathways of 5-HT2A Agonists
5-HT2A agonists act as powerful anti-inflammatory agents, inhibiting pro-inflammatory cytokines like TNF-alpha and IL-6 at sub-nanomolar concentrations.
5-HT2A Receptors as Master Regulators of Inflammation
Beyond neurotransmission, 5-HT2A receptors are abundantly expressed on vascular endothelial cells, immune lymphocytes, and cerebral microglia.
Potent Suppression of Tumor Necrosis Factor (TNF-alpha)
Research at LSU Health Sciences Center confirmed that 5-HT2A agonist activation profoundly blocks TNF-alpha-induced expression of inflammatory genes and adhesion molecules.
