Background: Regulation of TRPV1 by phosphoinositides is controversial. Results: ATP reactivates TRPV1 after run-down in excised inside-out patches by generating phosphoinositides; many other negatively charged lipids may also support TRPV1 activity. Conclusion: Despite its promiscuous activation, phosphoinositides are the key endogenous cofactors for TRPV1 activity. Significance: Our data may reconcile discordant data obtained in different experimental settings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
