One of the ways in which cell damage characteristic of aging can provoke inflammation is via the mislocalization of DNA. Either nuclear DNA or mitochondrial DNA can find its way to the cytosol, where it can trigger responses evolved to detect bacterial or viral infection, or severe cell damage. This creates a cascade of downstream signaling leading to an inflammatory response. In youth these events occur comparatively rarely, and in circumstances wherein immune response and potentially even cell death are beneficial. With age, however, there is a continued mild but growing level of dysfunction and consequent sustained inflammation that is never fully resolved. Such continual infl…
