Cette revue presente les etudes precliniques et cliniques mettant en evidence un impact du microbiote sur la perception de la douleur dans differents contextes pathologiques. Le lien entre le microbiote et l’activation des neurones est discute au travers de l’interaction directe hote–microbiote qui implique l’activation des nocicepteurs par les composes ou metabolites microbiens. De nouvelles etudes sur l’interaction entre le microbiote et le systeme nerveux devraient conduire a l’identification de nouveaux ligands microbiens et de medicaments ciblant les recepteurs de l’hote, qui pourraient a terme ameliorer la gestion de la douleur chronique et le « bien-etre ».","PeriodicalId":11303,"journal":{"name":"Douleur Et Analgesie","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84332318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ongoing research aims at either finding new treatments to replace opioids or reducing its heavy adverse effects due to long-term use: opioid-induced hyperalgesia and antinociceptive tolerance. In a recent study, Doyle et al. (2020) demonstrate that the activation of sphingosine-1-phosphate receptor subtype 1 (S1PR1) in the central nervous system contributes to morphine-induced hyperalgesia and antinociceptive tolerance in a rodent model of chronic pain. By targeting S1PR1 with molecules with functional antagonistic properties (some of which are FDA-approved for multiple sclerosis treatment), hyperalgesia and tolerance were significantly reduced without modifying morphine pharmacokinetics or efficacy.","PeriodicalId":11303,"journal":{"name":"Douleur Et Analgesie","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69373021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Depuis 2007, le ministère de la Santé finance des projets de prise en charge de la douleur. En 2013, une équipe algologique multidisciplinaire composée d’un médecin, un/une infirmière et un psychologue a été mise en place dans chaque hôpital aigu en Belgique. Sa mission est de sensibiliser les soignants à la nécessité d’une prise en charge correcte de la douleur dans le but de prévenir l’apparition d’une chronicisation.

The main entry pathway for SARS-CoV-2 into the cell is thought to be through binding to the angiotensin converting enzyme 2, but it seems another protein can induce its viral entry: neuropilin-1 receptor (NRP-1). NRP-1 is usually bound by vascular endothelial growth factor-A (VEGF-A), a - amongst other- pronociceptive factor. By binding to NRP-1, the Spike protein of SARS-CoV-2 blocks neuronal signaling, reducing the pro-nociceptive implication of VEGF-A. This analgesic role of SARS-CoV-2 gave rise to an increase in screenings for new compounds that could interfere with this pathway. Preventing VEGFA from binding to NRP1 opens new possibilities for therapeutic strategies in the field of neuropathic pain.","PeriodicalId":11303,"journal":{"name":"Douleur Et Analgesie","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69373826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
