Lysosomal dysfunction represents one of the most promising and rapidly evolving therapeutic target areas in neurodegenerative disease drug development. The lysosome serves as the cell's primary degradative organelle, and its impairment is increasingly recognized as a central mechanism in Parkinson's disease (PD), Alzheimer's disease (AD), and aging-related neurodegeneration 1. [1]
This investment landscape analyzes the therapeutic approaches, clinical pipeline, key players, and funding trends in lysosomal dysfunction-targeted therapies for neurodegenerative diseases. The field has attracted over $2 billion in investment since 2015, with particular focus on GBA-targeted approaches, autophagy enhancement, and gene therapy modalities. [2]
| Gene | Function | Disease Link | Carrier Frequency | [3]
|------|----------|--------------|-------------------| [4]
| GBA1 | Glucocerebrosidase | PD risk factor | 5-10% of PD patients |
| GAA | Acid alpha-glucosidase | Pompe disease, neurodegeneration | Rare |
| CTSD | Cathepsin D | AD, PD | Research stage |
| ATP13A2 | ATPase 13A2 | PARK9/Kufor-Rakeb | Rare |
| LAMP2 | Lysosomal membrane protein | Danon disease | Rare |
Heterozygous GBA1 mutations are the most common genetic risk factor for Parkinson's disease:
