The modulation of pain by neuropeptides (NP) is well known at the level of primary afferents and the spinal cord. However\, little data is available on their role in pain in the brain. The relaxin family includes relaxin\, which is present in the central nervous system (CNS) and has antifibrotic properties\, and relaxin-3\, which is strictly expressed in the CNS and has anxiolytic and antidepressant effects. Our objective is to study the modulation of pain by the neuropeptides relaxin and relaxin-3 in a mouse model of persistent inflammatory pain. \nOur results show that not only the relaxin-3 / RXFP3 system\, but also the relaxin / RXFP1 system\, which is still poorly explored in the CNS\, have analgesic effects in conditions of inflammatory pain. The sites of action of these peptide systems include cortical (cingulate cortex\, claustrum) and subcortical (amygdala) regions that regulate descending pathways and sensory integration in the spinal cord. Our data highlight the therapeutic potential of this peptide family\, whose role in pain has never been tested before. \nKeywords: Chronic pain\, amygdala\, anterior cingulate cortex\, relaxin\, relaxin-3. \nPublications\nAnimal models of pain: Diversity and benefits.\nAbboud C.\, Duveau\, A.\, Bouali-Benazzouz\, R.\, Massé\, K.\, Mattar\, J.\, Brochoire\, L.\, Fossat\, P.\, Boué-Grabot\, E.\, Hleihel\, W.\, and Landry\, M.
