202 Redox - Principles and Advanced Applications

The transient receptor potential (TRP) family includes cation-permeable ion channels activated by diverse stimuli ranging from chemical compounds, mechanical force and temperature. TRPA1, TRPV1, TRPC5, TRPM2, and TRPM7 are reported to be activated by reactive oxygen species (ROS). The sensitivity of TRPs to ROS is in part associated with pathogenesis caused by ROS and physiological adaptations to redox signals. The present review focuses on the well-defined ROS-sensitive TRP channels, TRPA1 and TRPM2, and summarizes recent reports regarding their activation mechanism by ROS and their relevance to pathological conditions and physiological functions in which ROS are involved.
