Abstract
TRESK is the most recently reported two-pore domain K+ channel, and different from other two-pore domain channels in gene, molecular structure, electrophysiological and pharmacological properties. Although the current knowledge of this potassium channel is inadequate, researches have demonstrated that TRESK is remarkablely linked to acute and chronic pain by activation of calcineurin. The fact that TRESK is sensitive to volatile anesthetics and localization in central nerve system implies that TRESK may play a very important role in the mechanism mediating general anesthesia. The further research of TRESK may contribute to explore the underlying mechanism of some pathological conditions and yield novel treatments for some diseases.
摘要
TRESK是最近新发现的一种双孔钾通道, 其在基因、分子结构、生理药理学特性方面不同于其他类别的双孔钾通道。本文总结了TRESK的研究现状, 并根据目前的研究资料推测TRESK有可能通过激活钙调神经磷酸酶参与了急性和慢性疼痛的发生, 是吸入性全身麻醉药的作用靶点, 有可能通过对钙调神经磷酸酶的激活影响记忆, 从而参与吸入性全身麻醉药的术后遗忘效应。对TRESK的深入研究有可能揭示某些病理生理状态的内在机制。
