LAMP2A-Mediated Autophagy Enhancement Blocks Alpha-Synuclein Propagation in Parkinson's Disease

Hypothesis

LAMP2A-Mediated Autophagy Enhancement Blocks Alpha-Synuclein Propagation in Parkinson's Disease

AAV9-mediated overexpression of LAMP2A enhances chaperone-mediated autophagy to selectively degrade pathological alpha-synuclein species, preventing Lewy body formation and blocking cell-to-cell propagation.

🧪 Overview

AAV9-mediated overexpression of LAMP2A enhances chaperone-mediated autophagy to selectively degrade pathological alpha-synuclein species, preventing Lewy body formation and blocking cell-to-cell propagation. Strongest mechanistic foundation with validated AAV platform and clear patient stratification via seed amplification assays.

No curated mechanism pathway recorded for this hypothesis.

⚖️ Evidence

⚖️ Evidence Matrix3 supports3 contradicts
Supports
LAMP2A overexpression reduces alpha-synuclein aggregation in cellular models
PMID:21300793
Supports
Chaperone-mediated autophagy activity declines with age and in Parkinson's disease
PMID:23939356
Supports
Pathological alpha-synuclein inhibits CMA creating positive feedback loop
PMID:23203657
Contradicts
CMA substrate competition risk—LAMP2A upregulation may deplete essential non-alpha-synuclein substrates causing toxicity
Contradicts
Oligomeric/fibrillar alpha-synuclein may be too large for CMA-mediated degradation even with enhanced LAMP2A
Contradicts
AAV9 dose-dependent dorsal root ganglion toxicity observed in high-dose trials
