Models of Immune Aging
2018
Abstract Biochemical changes, impaired immune responses to new antigens, and inflammation-based disorders are commonly found in aged individuals. Thus, many studies have addressed the immune system of healthy elderly, including centenarians, since a well-preserved immune system appears to be a major factor of longevity. Longitudinal studies in humans are complicated, as most immune changes associated with aging develop slowly. Human models of accelerated immune aging in clinical conditions allow exploring the age-related changes in the human immune system and the mechanisms of accelerated aging in chronic infections and autoimmunity. Even if they do not perfectly mimic immune function and i…
