Aging Fruit Fly Fat Bodies (image) Carnegie Institution for Science Share Print E-Mail Caption This image shows a comparison of lamin-B in the fat bodies of 10-day-old and 50-day-old fruit flies. As animals age, their immune systems gradually deteriorate, a process called immunosenescence. It is associated with systemic inflammation and chronic inflammatory disorders, as well as with many cancers. The causes underlying this age-associated inflammation, and how it leads to diseases, are poorly understood. New work in Carnegie's Yixian Zheng's lab sheds light on one protein's involvement in suppressing immune responses in aging fruit flies. It is published in Cell.
