Inflammaging (also known as inflamm-aging or inflamm-ageing) is a chronic, sterile, low-grade inflammation that develops with advanced age, in the absence of overt infection, and may contribute to clinical manifestations of other age-related pathologies.
This state, called chronic inflammation, also builds up naturally as we grow older, hence the term inflammaging, get it? If you’re 60 or older, you might see it in your blood tests, Tracey says.
[59] [60] [61] A substantial body of evidence implicates chronic inflammation as a critical driver of immune dysfunction, premature appearance of aging-related diseases, and immune deficiency. [ 59 ] [ 62 ] Many now regard HIV infection not only as an evolving virus-induced immunodeficiency, but also as chronic inflammatory disease. [ 63 ]
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.
T cells' functional capacity is most influenced by aging effects. Age-related alterations are evident in all T-cell development stages, making them a significant factor in immunosenescence. [27] T-cell function decline begins with the progressive involution of the thymus, which is the organ essential for T-cell maturation.
An immune-mediated inflammatory disease (IMID) is any of a group of conditions or diseases that lack a definitive etiology, but which are characterized by common inflammatory pathways leading to inflammation, and which may result from, or be triggered by, a dysregulation of the normal immune response.

The free radical theory of aging states that organisms age because cells accumulate free radical damage over time. [1] A free radical is any atom or molecule that has a single unpaired electron in an outer shell. [2] While a few free radicals such as melanin are not chemically reactive, most biologically relevant free radicals are highly ...
