摘要

Recent reports published in Cell Metabolism (Deriy et al., 2009; Li et al., 2009) suggest a role for the anion transporter CIC-3 in the secretion of insulin in pancreatic (3 cells by assisting acidification of large dense core vesicles (LDCVs). However, these reports contradict each other and our own recent work (Maritzen et al., 2008) in many ways and the mechanism by which CIC-3 influences LDCV exocy-tosis remains, in our eyes, unclear. Whereas the physiological importance of CIC-3 is obvious from the severe neurode-generation resulting from its disruption (Stobrawa et al., 2001), its function and localization are subject to considerable controversy. CIC-3 most likely operates as a Cr/H~+-exchanger, but some groups maintain that it is a Cl~ channel.
