New insight into inflammatory bowel disease may lead to better treatments
A newly discovered link between bacteria and immune cells sheds light on inflammatory bowel disease, an autoimmune condition that affects 1.6 million people in the United States, according to researchers at Washington University School of Medicine in St. Louis.
Finding points to a cause of chronic lung disease
Scientists have long suspected that respiratory viruses play a critical role in the development of chronic lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). Studying mouse and cell models of this process, researchers now have shown how immune cells dispatched to the lung to destroy a respiratory virus can fail to disperse after their job is done, setting off a chain of inflammatory events that leads to long-term lung problems.
Heart’s own immune cells can help it heal
The heart holds its own pool of immune cells capable of
helping it heal after injury, according to new research in mice at
Washington University School of Medicine in St. Louis.
Moving cells with light holds medical promise
Scientists at Washington University School of Medicine in St. Louis have shown they can coax cells to move toward a beam of light. The feat is a first step toward manipulating cells to control insulin secretion or heart rate using light.
Cholesterol buildup links atherosclerosis and macular degeneration
A new study raises the intriguing possibility that drugs prescribed to lower cholesterol may be effective against macular degeneration, a blinding eye disease. Researchers at Washington University School of Medicine in St. Louis have found that age-related macular degeneration shares a common link with atherosclerosis. Both problems have the same underlying defect: the inability to remove a buildup of fat and cholesterol.
