Significance of TRP channels in oxidative stress

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.
