New Technique Uses Carbon Nanoparticles to Fight Artery Plaque Buildup
Cardiovascular disease is a major concern that affects millions of people worldwide. One of the key factors contributing to this disease is the buildup of plaques in our arteries, which can lead to atherosclerosis and other serious health issues. Scientists have recently developed a groundbreaking new technique that uses carbon nanoparticles to target and reduce these dangerous plaques.
Plaques form in our arteries due to a buildup of fatty substances, cholesterol, dead cells, and other deposits. This process, known as atherosclerosis, can cause the walls of the arteries to thicken and stiffen, leading to restricted blood flow and increased risk of heart attacks and strokes.
A team of researchers from Michigan State University and Stanford University utilized nanoparticles thinner than a human hair, loaded with a drug that activates immune cells, to target and reduce plaque buildup in pigs with atherosclerosis. Through precise targeting, they were able to significantly reduce plaque levels in the animals.
“Using PET scans, we were able to measure the effects of the therapy on pig arteries,” explained biomedical engineer Bryan Smith of Michigan State University. “We showed that we can decrease inflammation levels in the plaque using both PET imaging and molecular assays.”
The nanoparticle treatment works by reactivating a process called efferocytosis, where the immune system clears out dead or damaged cells that contribute to plaque formation in the arteries. This targeted approach showed promising results in pigs, with no observable side effects or collateral damage to healthy cells.
With atherosclerosis being a leading cause of death in many countries, finding effective ways to reduce plaque buildup is crucial. Alongside healthy lifestyle changes, such as diet and exercise, this new nanoparticle therapy could offer a novel approach to combating cardiovascular disease.
The research team is now focused on preparing these nanoparticles for human clinical trials, with the hope of eventually bringing this innovative treatment to those at risk of atherosclerosis and related cardiovascular issues.
The study detailing this breakthrough technique has been published in Nature Communications, showcasing the potential for advancing nanoparticle-based therapies in the fight against cardiovascular disease.
