ER-Endolysosome Axis
This section details how the endoplasmic reticulum (ER) and endolysosomes communicate, focusing on lipid transfer, calcium signaling, and organelle positioning. It highlights how V-ATPase, essential for lysosomal acidification, influences ER homeostasis and stress responses, and how disruptions in this axis contribute to neurodegenerative conditions like Alzheimer's and Parkinson's diseases.
Golgi-Lysosome Crosstalk
This part explores the Golgi apparatus's role as a trafficking hub for lysosomal proteins and lipids. It emphasizes the importance of V-ATPase in maintaining Golgi pH gradients for proper enzyme sorting and delivery. Disruptions in Golgi-lysosome interactions, common in neurodegenerative diseases such as AD, PD, and Huntington's, are shown to lead to impaired protein processing and accumulation.
Mitochondria-Lysosome Interplay
This section examines the functional cooperation between mitochondria and lysosomes in metabolism and signaling, mediated by contact sites (MLCs). It describes how V-ATPase activity is crucial for mitochondrial quality control and how its dysfunction impairs mitophagy, leading to damaged mitochondria accumulation. Pathological feedback loops involving these organelles are central to AD, PD, and Huntington's diseases.
Pathological Cascade of Lysosomal Failure
Lysosomal Acidification Failure (V-ATPase)
→
Endomembrane System Dysfunction (ER, Golgi, Mitochondria)
→
Neurodegenerative Disease Progression (AD, PD, HD)
The research establishes a clear pathological cascade: initial failure of lysosomal acidification, primarily due to V-ATPase dysfunction, triggers widespread endomembrane system disruption, ultimately driving neurodegenerative disease progression.

Reduction in neuronal lysosomal degradation efficiency observed in early Alzheimer's models due to V-ATPase impairment.
A significant finding indicates a substantial drop in lysosomal degradation efficiency early in Alzheimer's disease progression, directly linked to compromised V-ATPase activity.
ER-Lysosome Crosstalk Dysfunction in Neurodegenerative Diseases
| Disease | Key Dysfunction | Impact |
|---|---|---|
| Alzheimer's Disease (AD) | PS1 mutation impairs V0a1 trafficking, calcium dysregulation |
|
| Parkinson's Disease (PD) | DRAM1/STIM1 tethering, VPS13C mutation, GBA1 mutations |
|
| Huntington's Disease (HD) | IRE1 activation, mHtt accumulation |

This table highlights how ER-lysosome contact site dysfunctions manifest uniquely across different neurodegenerative diseases, detailing the specific molecular pathways affected and their downstream consequences.
Therapeutic Targeting of V-ATPase in PD Models
A small molecule (C381) directly stimulated V-ATPase activity, restoring lysosomal acidity and improving proteolytic efficiency in Parkinson's disease models. This led to significant reductions in inflammation and neuropathology, improving cognitive function and neuronal survival. The study highlighted a 90% improvement in neuronal viability after C381 administration.
This case study demonstrates the therapeutic potential of directly targeting V-ATPase activity to restore lysosomal function and ameliorate Parkinson's disease pathology, offering a promising new treatment avenue.
