Nitric Oxide Signaling In Neurodegeneration plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Nitric Oxide Signaling In Neurodegeneration is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Nitric oxide (NO) is a versatile gaseous signaling molecule that plays complex roles in the nervous system. While NO serves important physiological functions in synaptic plasticity, blood flow regulation, and immune defense, dysregulated NO signaling contributes to neurodegeneration through nitrative stress, protein nitration, and mitochondrial dysfunction.
| Component | Function | Role in Neurodegeneration |
|---|---|---|
| nNOS (NOS1) | Neuronal nitric oxide synthase | Activity linked to excitotoxicity |
| eNOS (NOS3) | Endothelial NOS | BBB regulation, blood flow |
| iNOS (NOS2) | Inducible NOS | Chronic inflammation, high NO output |
| nSMase | Neutral sphingomyelinase | Ceramide generation, exosome release |
| sGC | Soluble guanylate cyclase | cGMP production |
| cGMP | Cyclic guanosine monophosphate | Second messenger |
| PDE | Phosphodiesterases | cGMP breakdown |
