Intermediate-conductance Ca2+-activated K+ channel: Research advances / 国际药学研究杂志

ABSTRACT

Intermediate-conductance Ca2+-activated K+ channel, also known as KCa3.1, IKCa and SK4, is widely distributed in fibroblasts, proliferating smooth muscle cells, endothelial cells, T lymphocytes, plasma cells, macrophages, and epithelial cells, and involved in the pathological and physiological processes such as vascular contraction, inflammation, calcification, tissue fibrosis, immune response, malignant tumor, internal and external secretory glands. In recent years, it has been found that blocking the KCa3.1 pathway or knockouting the gene can significantly prevent the pathophysiological process of its involvement. The recent use of the specific blocker TRAM-34 in animals and humans shows its safety and tolerability, providing a new direction for the treatment of related diseases. In this article, the research progress in KCa3.1 related diseases in recent years is reviewed.
