Immune cell age plays role in retinal damage in age-related macular degeneration

ApteStudying a mouse model of age-related macular degeneration, the leading cause of blindness in older Americans, scientists at the School of Medicine have found age is key in determining whether damaging blood vessels will form beneath the retina and contribute to vision loss. The scientists, led by principal investigator Rajendra Apte, discovered that specific immune cells called macrophages play a role in the disease process in older mice by failing to block the development of abnormal, leaky blood vessels behind the retina.

A solution to social security and education funding: it’s all part of the cycle of life

Bill Michalski/WUSTL PublicationsA loan finances a young person’s education. Twenty years later, that child is working, contributing to the economy and paying off their loan. As they repay, the capitalized value of the loan pays back their debt to the previous generation in the form of a pension.Funding social security and education are often thought of as separate issues. But the two issues should be linked, says economist Michele Boldrin, the Joseph Gibson Hoyt Distinguished Professor in Arts & Sciences at Washington University in St. Louis. In the same way that younger generations take care of their elders as a kind of “return” on their parent’s investment, so too can the U.S. invest in the educational needs of its children and have the accumulated debt be paid off to retirees when it comes due.
