Nattokinase promotes stroke recovery
We explored how nattokinase, a serine protease derived from the traditional food natto, can benefit individuals who have experienced strokes, particularly focusing on cognitive recovery. Our study specifically aimed to uncover whether nattokinase can act as an anti-post-stroke cognitive impairment (PSCI) agent by influencing blood factors that are crucial for brain health.

The results were telling. We discovered that nattokinase has protective effects against acute ischemic strokes and plays a significant role in promoting neurogenesis, which is the process of generating new brain cells. Through experiments conducted on rat models, we observed that nattokinase notably increases irisin levels in peripheral blood. Irisin is a protein that has emerged as an interesting player in enhancing cognitive functions.

By linking the increased levels of irisin to improved cognitive abilities, our findings suggest that nattokinase could be a promising therapy for those suffering from PSCI, positioning irisin as a potential target for treatment. Overall, our research highlights the exciting possibilities that nattokinase offers in the realm of stroke recovery and brain health.

Nattokinase shows promise in stroke
We examined how nattokinase (NK), a powerful enzyme, can benefit patients who suffer from strokes. Our research focused on the effects of NK in a model of transient middle cerebral artery occlusion (tMCAO), which simulates ischemic stroke and its aftermath. By administering different doses of NK to rats before they underwent surgery, we wanted to see if it could reduce brain damage and improve recovery.

Our observations revealed that NK treatment significantly reduced the size of brain injury and enhanced recovery from neurological issues. It also helped lower levels of harmful pro-inflammatory and coagulation substances while reducing oxidative stress markers in the affected brain area. These findings show NK’s potential in protecting the brain from the damaging effects of stroke.

Furthermore, we explored NK's protective properties in laboratory tests simulating neuron injury due to lack of oxygen and glucose. We found that it was effective in countering cell death across these models, working through various biological pathways. However, when we blocked NK's activity with a specific inhibitor, we noticed that its protective effects vanished, demonstrating that NK's enzymatic activity is crucial for its benefits.

Overall, this study highlights the multi-faceted protective role of nattokinase in brain injuries caused by ischemic events, confirming its potential as a therapeutic agent in stroke treatment.

Frequently Asked Questions

A stroke occurs when the blood supply to a part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. This can happen in two primary ways: an ischemic stroke, which occurs when a blood vessel supplying blood to the brain is obstructed, often due to a blood clot; and a hemorrhagic stroke, which occurs when a blood vessel in the brain bursts, leading to bleeding in or around the brain. The severity and outcome of a stroke can vary widely depending on the type, location, and amount of brain tissue affected, as well as the speed with which medical treatment is received.

Recognizing the symptoms of a stroke is crucial for prompt treatment and recovery. Common signs include sudden numbness or weakness in the face, arm, or leg, especially on one side of the body, confusion, trouble speaking or understanding speech, vision problems in one or both eyes, and difficulty walking, which may include dizziness or loss of balance coordination. The acronym FAST can help remember the key signs: Face drooping, Arm weakness, Speech difficulty, and Time to call emergency services. If you or someone you know exhibits these symptoms, it's vital to seek immediate medical attention, as timely intervention can significantly improve outcomes.
