Immunosenescence is the gradual deterioration of the immune system, brought on by natural age advancement. A 2020 review concluded that the adaptive immune system is affected more than the innate immune system. [1] Immunosenescence involves both the host's capacity to respond to infections and the development of long-term immune memory.
Senescence (/ s ɪ ˈ n ɛ s ə n s /) or biological aging is the gradual deterioration of functional characteristics in living organisms. Whole organism senescence involves an increase in death rates or a decrease in fecundity with increasing age, at least in the later part of an organism's life cycle.
A 2019 survey found that globally, we think old age begins at 66. When asked to describe it, we usually use the term wise (35%), followed by frail (32%), lonely (30%), and respected (25%). People ...
The concentration of this cytokine is usually very low or non-detectable in young adults though levels increase in old age and are very high in the elderly. [2] Moreover, elevated IL-6 has also been associated with disability and mortality in older adults. High serum levels are associated with cognitive impairment, low locomotion, and ...

Immunology is a branch of biology and medicine [1] that covers the study of immune systems [2] in all organisms.. Immunology charts, measures, and contextualizes the physiological functioning of the immune system in states of both health and diseases; malfunctions of the immune system in immunological disorders (such as autoimmune diseases, hypersensitivities, [3] immune deficiency, [4] and ...
Aging is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death. The hallmarks of aging are the types of biochemical changes that occur in all organisms that experience biological aging and lead to a progressive loss of physiological integrity, impaired function and, eventually, death.
