Patch-clamp studies of anion channels show a bewildering variety in their properties and regulation mechanisms.2 Amongst them, the anion channels activated by hypo-osmotic cell swelling (ICl,swell) have drawn attention because of their wide expression in virtually every vertebrate cell(s), including cardiac myocytes, and their critical roles in cell volume regulation.2–4 Cells need to regulate their volume in the face of several external and internal challenges. For this purpose, cells are endowed with various ion channels and transporters that become activated upon cell swelling or shrinkage. ICl,swell are also called by different names like volume-regulated
