Proteins in human blood coagulation can cleave alpha-synuclein, linking clotting enzymes to neurodegenerative pathology in Parkinson’s disease research published on October 28.
Parkinson’s disease remains a primary neurodegenerative pathology driven partially by aging, though its root causes stay largely unknown. They published their findings in the journal Nature Communications.
Scientists already knew that abnormal accumulation of the protein alpha-synuclein at the ends of neurons within the central nervous system contributes to the onset and progression of Parkinson’s disease. Yet the Italian team observed this interaction almost by chance when bringing thrombin and alpha-synuclein into contact. In theory, thrombin should have no relation to Parkinson’s pathology.
Instead, the study demonstrates that thrombin selectively cleaves alpha-synuclein. Consequently, an enzyme associated with blood functions and coagulation exerts effects on complex pathologies like Parkinson’s disease. The team established that this reaction occurs both in vitro and within a complex biological environment.
- Cellular Mechanism: Thrombin selectively cleaves the alpha-synuclein protein, which is abundant in the central nervous system.
- Experimental Scope: Researchers observed the reaction both in vitro and within a complex biological environment.
- Clinical Horizon: Future work will determine if this interaction detected in vitro actually forms in patients and if it will be possible to consider treatments for this disease.
The discovery bridges two physiological systems: vascular coagulation and central nervous system degeneration.
Future work by the Italian research group will determine whether this interaction detected in vitro actually forms in patients. Those upcoming investigations will also evaluate whether it will be possible to consider treatments for this disease.
| Biological Factor | Primary Function | Observed Interaction |
|---|---|---|
| Thrombin | Key enzyme of blood coagulation | Selectively cleaves alpha-synuclein |
| Alpha-Synuclein | Protein located at the ends of neurons | Abnormal accumulation contributes to Parkinson’s disease |
The research opens new avenues for exploring how an enzyme associated with blood functions and coagulation could have effects on complex pathologies like Parkinson’s disease, though determining if this interaction forms in patients remains necessary before any treatments can be considered.
