Macular degeneration linked to aging immune cells
From the Washington University of St. Louis School of Medicine website:
As people age, their immune systems age, too. And new research at Washington University School of Medicine in St. Louis suggests that aging immune cells increase the risk for age-related macular degeneration, a major cause of blindness in the United States.
Studying mice and cells from patients, the researchers found that as immune cells called macrophages age, they are more likely to contribute to the inflammation and abnormal blood vessel growth that damage vision in macular degeneration.
