10Panx is a mimetic inhibitory peptide of panx1, which is a mammalian protein ectopically expressed to function as a hemi-channel, that readily and reversibly inhibits the panx1 currents. 10Panx has attracted increasing attention as it allows scientists readily and reliably to examine inhibition of panx1 in cells where efficient and consistent delivery of siRNA is highly difficult. According to results of multiple previous studies, 10Panx selectively inhibits P2X7R-induced dye uptake without altering other aspects of R2X7R activation and ATP-evoked membrane currents, constitutive dye-uptake and hemichannel-like currents that are induced by the overexpression of panx1, and ATP-mediated IL-1β release.
