KCa1.1 Inhibition Attenuates Fibroblast‐like Synoviocyte Invasiveness and Ameliorates Disease in Rat Models of Rheumatoid Arthritis

Objective Fibroblast‐like synoviocytes (FLS) participate in joint inflammation and damage in rheumatoid arthritis (RA) and its animal models. The purpose of this study was to define the importance of KCa1.1 (BK, Maxi‐K, Slo1, KCNMA1) channel expression and function in FLS and to establish these channels as potential new targets for RA therapy. Methods We compared KCa1.1 expression levels in FLS from rats with pristane‐induced arthritis (PIA) and...
