SASP is a prime suspect for how #Senescent cells cause #Inflammation, #Cancer and #Fibrosis. But SASP is a mix of many secreted proteins, so the @MayoClinic looked closely at 24 factors.
1st, they show which factors are secreted by different cell types (in culture).

Next, and more exciting, they measured which SASP factors increase with age in human blood. #ChronicInflammation is an important mechanism of aging, but really defining #ChronicInflammation is hard and often not even attempted. So this detailed analysis is great.
Last, a thorough analysis of SASP factors predicting #Age, #Frailty & adverse outcomes post-surgery. This is important because #Aging is not a "disease". So speeding up the application of #AgingBiology to #Healthcare requires linking #MechanismsOfAging to reimbursable conditions.
