In conclusion, in our prospective community-based study, aging-related biomarkers were associated with measures of subclinical atherosclerosis cross-sectionally and with all-cause mortality prospectively, supporting the concept that these biomarkers may reflect the aging process in community-dwelling adults.
The Role of Aging Macrophages in Skin Inflammation

The immune system is complex and ages in complex ways, pressed by the lifetime burden of infection and rising levels of molecular damage that trigger many of the same innate immune responses as are produced by invading pathogens. The common innate immune cells known as macrophages play many roles in the body: defense against pathogens; destruction of errant cells; assisting in tissue maintenance and regeneration. Macrophages adopt different phenotypes (M1, M2, and others) depending on the task at hand.
The aging of the macrophage population, and also the analogous microglia of the central nervous system, is not as simple a matter as there being too many angry, inflammatory M1 macrophages and too few regenerative, anti-inflammatory M2 macrophages. There is, however, a sizable amount of evidence to suggest that this growing imbalance towards inflammatory macrophage behavior is a major cause of issues in older individuals. The perspective of this review paper on macrophage aging is a narrow one, focused ...
