Research Abstract |
The mRNA of two pore-domain potassium channel (K(2P)) was detected, and immunohistochemical findings showed TRAAK and TREK-2 expressions in the rat retina. However, patch-clamp study failed to detect K(2P) currents in isolated retinal cells. A KCNQ channel current was identified in porcine ciliary epithelial cells. Molecular biological analysis revealed that mRNAs of KCNQ1, 4 and 5 were expressed dominantly in ciliary body.
