Popis: According to the theory of inflammaging, aging of the body and the development of age-related diseases are a consequence of a chronic progressive generalized inflammatory process that develops and persists throughout life under the influence of negative factors of an infectious and non-infectious nature. Inflammaging has a number of features that distinguish it from acute inflammation: a chronic nature of inflammation, a low level of inflammation, blurry clinical state (in the early stages of clinical manifestations there may not be any at all). The key pathogenetic role in inflammation plays age-associated changes in the innate immune system, which are referred to in the English literature as “immunosenescence” and oxidative stress. The main source of reactive oxygen species and free radicals in the cells are mitochondria. With age, the concentration of intracellular glutathione, one of the main factors of the antioxidant protection of the cell, decreases and a pathological condition arises in which the rate of production of free radicals and reactive oxygen species significantly exceeds the antioxidant capabilities, which leads to the formation of oxidative stress and disruption of the structure and function of cells. Oxidative stress, inflammation and neuroinflammation are closely related to cognitive impairment, pathological state that is often observed in a group of elderly and senile patients. Further study of the pathogenesis of Inflammaging and the role of oxidative stress in it will potentially lead to development of methods to slow down aging and treat age-related cognitive impairments.
