Immunological Theory of Aging Essay - 748 Words

Throughout history, mankind has been obsessed with discovering a cure for any ailments or disorders that could disrupt or hinder their short lives, especially those to evade the aging process. With society becoming increasingly interested in everlasting beauty and living longer, the race to discover the main contributor toward aging begun in the early nineteen hundreds. In the midst of this quest, several biological theories had been developed. Among these theories is the immunity or immunological theory. This paper will discuss the immunological theory of aging by explaining the theory, giving a history of its origin and a description of further development within the evolution of the theory. Aging, as exhibited within the immunity†¦show more content†¦During this same time, immunologists and cell biologists were in a stalemate of debates focused on aging in respect to their individual fields. In the same period, a cytokine that was found to have promoted T-cell proliferation within cellular culture was discovered, promoting a flourish of immunology papers announcing the discovery of proof that the â€Å"unlimited growth of normal human T-cells† existed and directly countered the biologists’ Hayflick limit programmed aging theory (Effros, 2005). However, intrigued by the constant conflict of these two groups of researchers, Walford anxiously investigated whether or not the claim that human lymphocytes cultured were in truth restricted by the Hayflick limit was true (Effros, 2005). In order to come to a solution to the question, Walford systemically analyzed the proliferative potential of the lymphocytes. These cells derived from the peripheral bl ood of young adult donors were propagated in the cell culture with repeated stimulation of an antigen (Effros, 2005). Continuous exposure to the T-cell specific growth factor interleukin-2, concluded with a mean number of population doublings, showed a steady decrease between the ages of 25 and 40 (Effros, 2005). With the continuous repeat of this data, Walford’s reasoning began toShow MoreRelatedAn Accurate Plan Of Care For Older Adults1522 Words   |  7 PagesAs individuals age changes occur physiologically that are part of normal aging. These changes occur in all organ systems and can impact an individual’s quality of life. The changes related to aging can be attributed to an individual’s genetic make up, lifestyle, physical activity, and dietary lifestyle. Being able to differentiate between normal changes in aging against disease process is important because it can help clinicians develop a plan of care (Boltz, Capezuti, Fulmer, Zwicker, 2012).

There are many theories of biological aging, such as the Cellular Aging Theory, Immunological Theory, and the Wear and Tear Theory. The Cellular Aging theory describes the process of aging in which cells slow their number of replication, thus giving each species a â€Å"biological clock that determines its maximum life span† and how quicklyRead MoreHow We Can Live Longer Essay1444 Words   |  6 Pages I.

It is very important to see how people change as they age and the various experiences they go through. One of the most common diseases among older people is dementia. Among the different types of dementia, the most prevalent one is Alzheimer’s disease (AD). It is important to look at all of the signs and symptoms of each type of dementia to see which specific type best describes a person’s condition.

The sarcophagus was designed to last about 30 years, and current designs would create a new shelter with a lifetime of 100 years. But radioactivity in the damaged reactor would need to be contained for 100,000 years
