T cells from patients with melanoma can trigger a protective immune response against the disease according to a new study out of University Hospitals Case Medical Center Seidman Cancer Center and Case Western Reserve University School of Medicine. Published in the July/August issue of Journal of Immunotherapy, these new findings demonstrate that T cells derived from lymph nodes of patients with melanoma can be expanded in number and activated in the laboratory for intravenous administration in the treatment of patients.

Around half of all breast cancer patients could one day benefit from having the cheap and widely-available female hormone progesterone added to their treatment, according to Cancer Research UK funded research published in Nature today. Tumours fuelled by the female hormone oestrogen are treated with drugs like tamoxifen to block oestrogen receptors, which cause cancer cells to grow.

New research from the University of Copenhagen and Herlev and Gentofte Hospital shows that high vitamin C concentrations in the blood from the intake of fruit and vegetables are associated with a reduced risk of cardiovascular disease and early death. Fruit and vegetables are healthy. We all know that. And now there is yet another good reason for eating lots of it.

Flu vaccines can be something of a shot in the dark. Not only must they be given yearly, there's no guarantee the strains against which they protect will be the ones circulating once the season arrives. New research by Rockefeller University scientists and their colleagues suggests it may be possible to harness a previously unknown mechanism within the immune system to create more effective and efficient vaccines against this ever-mutating virus.

A new analysis of dietary patterns among more than 100,000 Americans suggests that frequent consumption of citrus - namely whole grapefruit and orange juice - may be associated with an increased risk of melanoma. Melanoma risk was 36% higher in people who consumed citrus fruit or juice at least 1.6 times daily compared to those who consumed them less than twice per week.

As the South Korean epidemic of Middle East Respiratory Syndrome (MERS) continues unabated, researchers have raced to find treatments for the deadly virus, which has killed more than 400 people since it was first discovered three years ago in Saudi Arabia. Now, scientists at the University of Maryland School of Medicine and Regeneron Pharmaceuticals, Inc., have discovered and validated two therapeutics that show early promise in preventing and treating the disease,

A new study suggests that people with a genetic predisposition to high blood pressure have a lower risk for Alzheimer's disease. However, authors conclude the connection may have more to do with anti-hypertension medication than high blood pressure itself.
