How does PIKFYVE inhibition activate unconventional protein clearance via exocytosis?

PARTIALLY ADDRESSED

The abstract describes a novel mechanism where PIKFYVE inhibition triggers exocytosis of aggregation-prone proteins, but the molecular pathway is not explained. Understanding this mechanism is critical since protein aggregation is central to ALS pathogenesis and this represents a potentially new therapeutic approach. Gap type: unexplained_observation Source paper: PIKFYVE inhibition mitigates disease in models of diverse forms of ALS. (2023, Cell, PMID:36754049)
