Cell Based Immunotherapy For Neurodegenerative Diseases is a treatment approach for neurodegenerative diseases. This page provides comprehensive information about its mechanism of action, clinical evidence, and therapeutic potential.
Cell-based immunotherapy leverages the patient's own immune cells or engineered cells to target pathological proteins and modulate neuroinflammation in neurodegenerative diseases. This approach combines cellular therapy with immunotherapy principles, offering potential disease-modifying effects.
Chimeric antigen receptor (CAR) T cells are engineered to recognize specific disease-related targets:
T cell collection → Gene engineering (CAR construct) → Cell expansion
→ Reinfusion → Target recognition → Immune response:
├── Direct target killing
├── Cytokine release
├── Immune activation
└── Long-term surveillance
| Target | Disease | Development Stage |
