Red/near Infrared Light Stimulates Release Of An Endothelium-Dependent Vasodilator And Rescues Vascular Dysfunction In A Diabetes Model.
Research Summary
This laboratory study investigated whether 670 nm light could relax blood vessels through nitric-oxide-related signalling. It examined a possible mechanism rather than testing a treatment in patients.
Who Or What Was Studied?
Experiments used isolated mouse blood vessels, including a diabetic mouse model, and cultured human microvascular endothelial cells. Human cells in culture are not human trial participants.
What Did The Research Show?
- Light increased vessel dilation, including in vessels from diabetic mice. Removing the vessel lining or scavenging nitric oxide abolished the response.
- The findings suggest that the vessel lining releases nitric-oxide-carrying substances in response to light.
Limitations And Interpretation
- These experiments do not demonstrate improved circulation, symptom relief or healing in people with diabetes.
- An isolated-vessel response cannot establish an effective or safe whole-body treatment protocol.
