Researchers at MIT have made significant advances toward a novel therapeutic device that can selectively provide signals to cells traveling through the bloodstream. The technology leverages cell rolling, a biological process that slows down cells as they flow through blood vessels, allowing them to sense signals from nearby tissues.
Researchers have successfully transplanted purified adult stem cells into the hearts of severe angina patients, showing a significant reduction in pain and improved daily functioning. The study, led by Northwestern University's Douglas Losordo, provides evidence for the safety and therapeutic potential of this cell therapy approach.
A new study by researchers at the University of Miami reveals that nicotine can accelerate the progression of kidney disease in smokers. Human mesangial cells were found to express nicotinic receptors, which are activated by nicotine and lead to increased cell proliferation and fibronectin production.
Researchers discovered that a new drug called AMD3100 can rapidly mobilize blood vessel-forming cells to reach injured areas, accelerating healing. This breakthrough has the potential to improve treatment outcomes for heart attacks and strokes.
Researchers have identified four key genes in Porphyromas gingivalis that allow it to infect and survive inside artery cells. The study found that mutating these genes impaired the bacterium's ability to invade cells, providing a potential target for therapeutic interventions.
Researchers have successfully used a gene therapy approach to deliver telomerase, an enzyme that lengthens cell lifespan, without causing tumors in human patients. The technique allows for the growth of blood vessels in patients with vascular disease, offering new treatment options.
Researchers extended the lifespan of blood vessel cells from elderly donors, enabling successful culture of engineered blood vessels. This breakthrough advances tissue engineering towards treating vascular disease.
Scientists discover NKT cells primarily patrol liver blood vessels, showcasing agility and rapid movement. The study reveals surprises about NKT cell behavior, including their ability to survive without the CXCR6 gene.
A new study published in Heart found that individuals with giant cell arteritis (GCA) have a significantly higher risk of cardiovascular disease compared to healthy adults. The prevalence of GCA is estimated at one per every 500 seniors, and patients with this condition are more than twice as likely to experience heart attacks or strokes.
Researchers found that treatment with Viagra increases therapeutic levels of nitric oxide in heart cells, stabilizing mitochondria and reducing cell death. This may lead to new treatments for patients with heart failure where loss of cells is primarily due to apoptosis.
A Mount Sinai School of Medicine study identifies the shared precursor cell, called the hemangioblast, in early mouse embryos. This finding provides strong proof for the existence of a common origin for vascular cells and hematopoietic cells.
A recent study has found that gut bacteria interact with the intestine to regulate blood supply, with Bacteroides thetaiotaomicron stimulating blood vessel development. The research suggests a key developmental program shared by intestinal bacteria and their host is essential for healthy development.
Researchers have discovered that adult blood stem cells can function to make blood vessels, a breakthrough that could lead to new treatments for circulatory diseases. The discovery was made using genetically engineered mice with green glowing stem cells, which were able to form new capillary beds in the eyes.
Glioma cells induce angiogenesis by interacting with host vasculature and sprouting new vessels, defying the cooptation model. Vascular outgrowth occurs as a continuous process of growth and remodeling, starting early in tumor progression.
Scientists at the University of Illinois have developed a novel laser technique to study chromatin movement in living cells. By measuring the movement of DNA, they found evidence of subdiffusion within the cell nucleus, suggesting that molecular crowding is crucial for life.
Researchers at the University of Pittsburgh Cancer Institute found that triggering an anti-tumor immune response significantly potentiates the effects of the anti-angiogenic drug endostatin. The study showed that half of treated animals experienced complete and permanent regression of tumors, suggesting a highly effective cancer therapy.
Researchers at Rice University and the University of Texas-Houston Health Science Center have tracked the path that a polymer-DNA complex takes through a cell to its nucleus, where the new DNA can be read. This study improved our understanding of gene delivery and provided new knowledge for designing better nonviral carriers.
Researchers found that high concentrations of nitric oxide in osteoclasts prevent excessive bone resorption, a process linked to diseases like osteoporosis. This discovery may lead to new strategies for preventing bone loss and potentially treating inflammatory conditions.
University of Maryland scientists have discovered a way to transform sodium channels into calcium channels, which could lead to the development of new treatments for heart failure and various neurological conditions. This breakthrough, reported in the journal Science, opens up novel targets for drug discovery and molecular medicine.
Cornell researchers have developed a new technique to measure serotonin concentration in live cells, using pulsed lasers for excitation. This method allows for the visualization of serotonin secretory granules in real-time without damaging the cell or requiring external fluorescent markers.
