The Parkinson disease (PD) genetic LRRK2 gain-of-function mutations may relate to the ER pathological changes seen in PD patients at postmortem. Human induced pluripotent stem cell (iPSC)-derived neurons with the PD pathogenic LRRK2 G2019S mutation exhibited neurite collapse when challenged with the ER Ca<sup>2+</sup> influx sarco/ER Ca<sup>2+</sup>-ATPase inhibitor thapsigargin (THP). Baseline ER Ca<sup>2+</sup> levels measured with the ER Ca<sup>2+</sup> indicator CEPIA-ER were lower in LRRK2 ...[more]
