Nattokinase Promotes Post-stroke Neurogenesis and Cognition Recovery via Increasing Circulating Irisin.
The therapeutic potential of treatments for post-stroke cognitive impairment (PSCI) is severely limited by the autonomic regeneration capacity of the adult brain. Nattokinase (NK), a serine protease from the traditional food natto, has many beneficial effects on the cardiovascular system by modulating the blood system. While the role of blood factors in neurogenesis and cognition is well-established, it remains unclear whether NK can serve as an anti-PSCI agent through these factors. Our study demonstrates that NK protects against acute ischemic stroke and impressively promotes neurogenesis in rat models by increasing peripheral blood irisin, leading to improved cognitive functions. Our findings demonstrate NK to be a promising candidate for treating PSCI, and we also highlight irisin as a novel target of NK, suggesting its potential role in the peripheral blood-to-brain axis.

Cerebellar hemorrhage provoked by combined use of nattokinase and aspirin in a patient with cerebral microbleeds.
Nattokinase is used as a health-promoting medicine for preventing thrombosis due to its fibrinolytic activity. Cerebral microbleed is remnant of blood extravasations from the damaged vessels related to cerebral microangiopathies. We report a patient, having used aspirin for secondary stroke prevention, who had an acute cerebellar hemorrhage after taking nattokinase 400 mg daily for 7 consecutive days. In addition to the hemorrhagic lesion, multiple microbleeds were demonstrated on brain MR images. We suggest that nattokinase may increase risk of intracerebral hemorrhage in patients who have bleeding-prone cerebral microangiopathy and are receiving other antithrombotic agent at the same time.
