RecruitingMicroRNA Regulation of Chronic Inflammation During AgingThis is an observational study enrolling healthy individuals aged 18-35 and 65y and older to determine the health of immune cells in the blood and how these cells create inflammation and effect health as we age. It is hoped that once the nature of this relationship has been discovered we can more effectively design therapies to reduce this inflammation. The enrollment goal is 40 participants. The study will occur over the course of 1 month which will include a screening visit and a second visit where the participants will undergo an oral glucose tolerance test, blood draws and leg strength \& exercise tests.
