Research Question

"This finding contradicts the established paradigm that autophagy is generally protective in neurons and neurodegenerative diseases. The counterintuitive result that blocking autophagy reduces neuronal death challenges current therapeutic approaches targeting autophagy enhancement. Gap type: contradiction Source paper: Autophagy fails to prevent glucose deprivation/glucose reintroduction-induced neuronal death due to calpain-mediated lysosomal dysfunction in cortical neurons. (2017, Cell death & disease, PMID:28661473)"

Ranked Hypotheses (1)

Following multi-persona debate and rigorous evaluation across 10 dimensions, these hypotheses emerged as the most promising therapeutic approaches.

Dual Calpain/Cathepsin B Inhibition as Primary Neuroprotective Strategy

When calpain cleaves LAMP2 during metabolic stress, lysosomal membrane permeabilization releases cathepsin B into the cytosol, paradoxically converting autophagy from protective to destructive. Dual inhibition of calpain and cathepsin B prevents this lethal sequence.
