Description
Summary:In the present thesis, and in the context of the Sigma-1 receptor (σ1R) research project running at the pharmaceutical company ESTEVE, we addressed, at the preclinical level, the role played by selective σ1R antagonism/blockade in nociception in order to ascertain the therapeutic interest of σ1R antagonists in pain treatment. Taking advantage of using selective σ1R pharmacological tools and the in vivo microdialysis technique, the mechanism and the site of action of selective antagonism of σ1R were investigated in pain conditions involving sensitization (formalin model) as well as in acute thermal pain (tail-flick test) to look at the modulation of opioid-induced efficacy and safety-related outcomes. The results of this thesis provide new knowledge about σ1R as a pain target suitable for therapeutic intervention to get analgesia and support the use of σ1R antagonists as opioid adjuvants to treat pain conditions
