Fight Aging!
As illustrated in today's research commentary, all too many researchers continue to view aging as something distinct from age-related disease, and this inevitably leads to a poor approach to research and development. In this case, a rejection of the idea that rejuvenation is possible in principle at the present time. If one believes that aging...
Fight Aging!
Macrophages are a type of innate immune cell, and like all immune cells are involved in a great many processes in the body, ranging from tissue regeneration to clearing out molecular waste and debris to destruction of pathogens. Macrophages, and the similar microglia of the central nervous system, adopt different phenotypes, known as polarizations, depending...
Fight Aging!
Chronic inflammation is an important aspect of aging, a process that stems from low-level biochemical damage and cellular dysfunction, and that then contributes to the progression of age-related disease and tissue dysfunction. Chronic inflammation sustained over years accelerates all of the common fatal age-related conditions: it disrupts tissue maintenance, and leads to fibrosis, immune dysfunction,...
Hypoxia-Inducible Factors in Vascular Aging
Stress response mechanisms have been shown to be important in the way in which metabolism determines longevity in any given species. Short-lived species exhibit great plasticity of life span in response to stresses such as heat, cold, nutrient deprivation, and hypoxia. A mild or transient stress can trigger lasting upregulation of cell and tissue maintenance...
Inhibition of Autophagy in Mice Produces Signs of Accelerated Aging
One must always be careful in the interpretation of studies of aging in which essential biological processes are disrupted. There are any number of ways to disrupt essential biological functions to produce all sorts of consequent damage. But damage that isn't relevant to the normal processes of aging can nonetheless produce results that look very...
Fight Aging!
Today's research materials are representative of numerous initiatives aiming to produce taxonomies of the biochemistry of aging, to catalog the observed variations. Yet, with the exception of a very small number of unlucky souls bearing rare harmful mutations, we all age for the same underlying reasons. The same processes of metabolism produce the same forms...
