How does sumatriptan modulate nociceptive transmission within the trigeminovascular system?
OPEN
While the authors conclude that sumatriptan prevents PACAP38-induced migraine by modulating trigeminovascular nociception, the specific molecular and cellular mechanisms of this modulation are not elucidated. Understanding these pathways is critical for developing more targeted migraine therapeutics.
