TLDR
It is proposed that inflammaging can be flanked by anti-inflammaging as major determinants not only of immunosenescence but eventually of global aging and longevity.About:

Chronic Inflammation (Inflammaging) and Its Potential Contribution to Age-Associated Diseases
TL;DR: The session on inflammation of the Advances in Gerosciences meeting held at the National Institutes of Health/National Institute on Aging in Bethesda on October 30 and 31, 2013 was aimed at defining these important unanswered questions about inflammaging.
Journal ArticleDOI
Four faces of cellular senescence
TL;DR: The challenge now is to understand the senescence response well enough to harness its benefits while suppressing its drawbacks.
Journal ArticleDOI
Inflammaging: a new immune–metabolic viewpoint for age-related diseases
TL;DR: It is argued that chronic diseases are not only the result of ageing and inflammaging; these diseases also accelerate the ageing process and can be considered a manifestation of accelerated ageing, and the use of new biomarkers capable of assessing biological versus chronological age in metabolic diseases is proposed.
Journal ArticleDOI
Cellular senescence and the senescent secretory phenotype: therapeutic opportunities.
TL;DR: This work reviews the mechanisms that induce senescence and the SASP, their associations with chronic disease and frailty, therapeutic opportunities based on targeting senescent cells and the ASP, and potential paths to developing clinical interventions.

TL;DR: This article showed that spermidine, a natural polyamine whose intracellular concentration declines during human ageing, markedly extended the lifespan of yeast, flies and worms, and human immune cells.

Pleiotropy, natural selection, and the evolution of senescence
TL;DR: August Weismann's theory is subject to a number of criticisms, the most forceful of which are: 1) The fallacy of identifying senescence with mechanical wear, 2) the extreme rarity, in natural populations, of individuals that would be old enough to die of the postulated death-mechanism, 3) the failure of several decades of gerontological research to uncover any deathmechanisms, and 4) the difficulties involved in visualizing how such a feature could be produced

Pleiotropy, Natural Selection, and the Evolution of Senescence
TL;DR: A new individual entering a population may be said to have a reproductive probability distribution as discussed by the authors, where the reproductive probability is zero from zygote to reproductive maturity, i.e., the individual will have no reproductive capability from birth to maturity.

Inflamm‐aging: An Evolutionary Perspective on Immunosenescence
Claudio Franceschi,Massimiliano Bonafè,Silvana Valensin,Fabiola Olivieri,Maria De Luca,Enzo Ottaviani,Giovanna De Benedictis +6 more
TL;DR: The beneficial effects of inflammation devoted to the neutralization of dangerous/harmful agents early in life and in adulthood become detrimental late in life in a period largely not foreseen by evolution, according to the antagonistic pleiotropy theory of aging.

TL;DR: The results provide a causative link between mtDNA mutations and ageing phenotypes in mammals by creating homozygous knock-in mice that express a proof-reading-deficient version of PolgA, the nucleus-encoded catalytic subunit of mtDNA polymerase.

The gut flora as a forgotten organ
Ann M O'Hara,Fergus Shanahan +1 more
TL;DR: The flora has a collective metabolic activity equal to a virtual organ within an organ, and the mechanisms underlying the conditioning influence of the bacteria on mucosal homeostasis and immune responses are beginning to be unravelled.
