Multiple Roles of Transient Receptor Potential (TRP) Channels in Inflammatory Conditions and Current Status of Drug Development

[ Vol. 13 , Issue. 3 ]


Olivier Radresa, Michel Pare and Jeffrey S. Albert   Pages 367 - 385 ( 19 )


During inflammation, several Transient Receptor Potential (TRP) channels are directly or indirectly activated by inflammatory signaling molecules and microenvironmental changes including heat, oxidative conditions or low pH. In either case, specific TRP isoforms participate in chains of pro- or anti-inflammatory signaling cascades often including activation of transcription factors, protein kinases and phospholipases, which result in signal integration or amplification. In a few cases, their potentials as therapeutic targets for inflammatory conditions like pruritis, cystitis, dermatitis, asthma among other conditions are investigated pre-clinically or clinically by pioneering academic groups and industries. Significant efforts are still devoted to the understanding of the detailed physiological roles played by TRP channels during inflammation. This review intends to summarize key biological findings and reports of drug discovery activities when available, in an overview of the current status and recent developments in the field.
