Cell Biology Persistent Pores in Insulin Secretion

During stimulated secretion, a secretory granule fuses with the plasma membrane to release secretory granule contents. Takahashi et al. have used two-photon excitation imaging to reveal the dynamics of the fusion pore during insulin secretion from pancreatic islets. The lifetime of the pore, which was made up mostly of membrane lipids, was much longer than anticipated from other studies with single cells.
