Abstract
- K<superscript>+</superscript> channels are involved in many critical functions in lung physiology. Recently, the family of Ca<superscript>2+</superscript>-activated K<superscript>+</superscript> channels (K<subscript>Ca</subscript>) has received more attention, and a massive amount of effort has been devoted to developing selective medications targeting these channels. Within the family of K<subscript>Ca</subscript> channels, three small-conductance Ca<superscript>2+</superscript>-activated K<superscript>+</superscript> (K<subscript>Ca</subscript>2) channel subtypes, together with the intermediate-conductance K<subscript>Ca</subscript>3.1 channel, are voltage-independent K<superscript>+</superscript> channels, and they mediate Ca<superscript>2+</superscript>-induced membrane hyperpolarization. Many K<subscript>Ca</subscript>2 channel members are involved in crucial roles in physiological and pathological systems throughout the body. In this article, different subtypes of K<subscript>Ca</subscript>2 and K<subscript>Ca</subscript>3.1 channels and their functions in respiratory diseases are discussed. Additionally, the pharmacology of the K<subscript>Ca</subscript>2 and K<subscript>Ca</subscript>3.1 channels and the link between these channels and respiratory ciliary regulations will be explained in more detail. In the future, specific modulators for small or intermediate Ca<superscript>2+</superscript>-activated K<superscript>+</superscript> channels may offer a unique therapeutic opportunity to treat muco-obstructive lung diseases.
