New early detection studies of lung cancer in non-smokers launched

Government and private sector cancer scientists today launched a research partnership to find biomarkers for lung cancer that develops in people who have never smoked. The research studies are designed to create a better understanding of the biology of lung cancer and to develop a test to detect early-stage lung cancer in lifetime nonsmokers.

Discovery of process that controls T cell growth

Identifying one of the processes that plays a role in naïve and memory T-cells' growth and production could one day lead to better vaccines and possibly more effective cancer immunotherapy, said researchers at Baylor College of Medicine and Texas Children's Hospital in a report that appears in the current edition of Nature Immunology.

Discovery of gene associated with narcolepsy

Scientists funded by the National Institutes of Health have identified a gene associated with narcolepsy, a disorder that causes disabling daytime sleepiness, sleep attacks, irresistible bouts of sleep that can strike at any time, and disturbed sleep at night. The gene has a known role in the immune system, which strongly suggests that autoimmunity, in which the immune system turns against the body's own tissues, plays an important role in the disorder.
