Research Overview
Nociceptin
Nociceptin is a major pain-pathway peptide in the spinal cord, brainstem, and trigeminal system. Its relevance to migraine and neuropathic pain is mainly preclinical, where receptor-selective tools are being explored.
Somatostatin
Somatostatin reduces release of multiple excitatory mediators and can suppress pain signaling in preclinical and limited translational work. Its analgesic use is not standard, but the peptide is real and mechanistically relevant to pain control.
