Reactive oxygen species induce oxidative stress, leading to cell damage, but also function as signal transduction molecules. Transient receptor potential (TRP) channels have been attracting increasing attention as Ca2+-permeable channels that sense environmental changes. The members of one class of TRP channels have emerged as reactive oxygen species sensors. The significance of Ca2+ signaling induced by the activation of reactive oxygen species-sensitive TRP channels under pathological conditions is currently being elucidated. The selective inhibition of reactive oxygen species-sensitive TRP channels represents a future challenge that may lead to new therapeutic strategies for the suppression of reactive oxygen species-related diseases.
Keywords: Oxidative stress; Reactive oxygen species; TRP channels; TRPA1; TRPM2.
