What molecular mechanisms link GBA1 mutations to ER calcium homeostasis impairment in neurons?

OPEN

The study demonstrates that GBA1 mutations cause ER calcium dysregulation, but the mechanistic pathway connecting lysosomal glucocerebrosidase deficiency to ER calcium handling is unexplained. Understanding this connection is critical since ER calcium disruption appears to be an early event triggering the downstream apoptotic cascade.
