Molecular chatter makes for a ‘hot tumor’

A Ludwig Cancer Research study has deciphered a complex molecular conversation between cancer and immune cells that is key to orchestrating the successful invasion of tumors by T cells that kill cancer cells. “We show that two key chemokines, CCL5 and CXCL9, are universally implicated in T cell infiltration across all solid tumors,” said George Coukos, who directs the Lausanne […]

Novel antioxidant makes old blood vessels seem young again

Older adults who take a novel antioxidant that specifically targets cellular powerhouses, or mitochondria, see age-related vascular changes reverse by the equivalent of 15 to 20 years within six weeks, according to new University of Colorado Boulder research. The study, published this week in the American Heart Association journal Hypertension, adds to a growing body of evidence suggesting pharmaceutical-grade nutritional […]

New technique makes heart valve replacement safer for some high-risk patients

Scientists have developed a novel technique that prevents coronary artery obstruction during transcatheter aortic valve replacement (TAVR), a rare but often fatal complication. The method, called Bioprosthetic Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA), will increase treatment options for high-risk patients who need heart valve procedures. The findings by researchers at the National Institutes of Health […]
