Specifically, miRNAs control macromolecular complexes in neurons, glia and immune cells and regulate signals used for neuro-immune communication in the pain pathway. Therefore, miRNAs may be hypothesized as critically important master switches modulating chronic pain. In particular, understanding the concerted function of miRNA in the regulation of nociception and endogenous analgesia and defining the importance of miRNAs in the circuitries and cognitive, emotional and behavioral components involved in pain is expected to shed new light on the enigmatic pathophysiology of neuropathic pain, migraine and complex regional pain syndrome. Specific miRNAs may evolve as new druggable molecular targets for pain prevention and relief. Furthermore, predisposing miRNA expression patterns and inter-individual variations and polymorphisms in miRNAs and/or their binding sites may serve as biomarkers for pain and help to predict individual risks for certain types of pain and responsiveness to analgesic drugs. miRNA-based diagnostics are expected to develop into hands-on tools that allow better patient stratification, improved mechanism-based treatment, and targeted prevention strategies for high risk individuals.}, language = {en} } @article{OehlerKistnerMartinetal.2017, author = {Oehler, Beatrice and Kistner, Katrin and Martin, Corinna and Schiller, J{\"u}rgen and Mayer, Rafaela and Mohammadi, Milad and Sauer, Reine-Solange and Filipovic, Milos R. and Nieto, Francisco R. and Kloka, Jan and Pfl{\"u}cke, Diana and Hill, Kerstin and Schaefer, Michael and Malcangio, Marzia and Reeh, Peter W. and Brack, Alexander and Blum, Robert and Rittner, Heike L.}, title = {Inflammatory pain control by blocking oxidized phospholipid-mediated TRP channel activation}, series = {Scientific Reports}, volume = {7}, journal = {Scientific Reports}, number = {5447}, doi = {10.1038/s41598-017-05348-3}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-158536}, year = {2017}, abstract = {Phospholipids occurring in cell membranes and lipoproteins are converted into oxidized phospholipids (OxPL) by oxidative stress promoting atherosclerotic plaque formation. Here, OxPL were characterized as novel targets in acute and chronic inflammatory pain. Oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine (OxPAPC) and its derivatives were identified in inflamed tissue by mass spectrometry and binding assays. They elicited calcium influx, hyperalgesia and induced pro-nociceptive peptide release. Genetic, pharmacological and mass spectrometric evidence in vivo as well as in vitro confirmed the role of transient receptor potential channels (TRPA1 and TRPV1) as OxPAPC targets. Treatment with the monoclonal antibody E06 or with apolipoprotein A-I mimetic peptide D-4F, capturing OxPAPC in atherosclerosis, prevented inflammatory hyperalgesia, and in vitro TRPA1 activation. Administration of D-4F or E06 to rats profoundly ameliorated mechanical hyperalgesia and inflammation in collagen-induced arthritis. These data reveal a clinically relevant role for OxPAPC in inflammation offering therapy for acute and chronic inflammatory pain treatment by scavenging OxPAPC.}, language = {en} }
