The Path to the Clinic for First Generation Senolytic Therapies
Senolytic therapies selectively destroy lingering senescent cells in old tissues, improving health as a result. Senescent cells, while never very large in absolute numbers, even in late life, actively maintain a degraded state of tissue and organ function via secretions that provoke chronic inflammation, detrimental alterations to the behavior of normal cells, and harmful remodeling of tissue structure, such as the development of fibrosis. A large number of animal studies have demonstrated rapid rejuvenation and reversal of aspects of specific age-related conditions to result from clearance of senescent cells. The best of ...

The Inflammatory Burden of Infection Accelerates Hematopoietic Aging
Researchers here provide evidence for the inflammatory burden of infection to accelerate the aging of the hematopoietic system responsible for generating blood and immune cells. A greater exposure to infectious disease throughout life may be causing presently irreversible damage in the stem cell populations that produce the immune system. It is already known that restoration of these stem cell populations is an important target for the rejuvenation of the aged immune system, along with regeneration of the thymus and clearance of misconfigured and damaged populations of immune cells. It is unclear as to which of the many po...

Cellular Senesence, a Key Target in the Treatment of Aging
Scores of animal studies provide compelling evidence for cellular senescence to contribute meaningfully to many age-related conditions, and yet more such studies demonstrate rapid and sizable rejuvenation via targeted removal of senescent cells in old animals using varieties of senolytic therapy. Senescent cells are created constantly in the body, the result of cells reaching the Hayflick limit on replication, tissue injury, or encountering cellular damage or toxicity. When an individual is young, these newly senescent cells are near all removed by a combination of programmed cell death and the actions of the immune system...

In Other Words: Not All Cultures Are Human
The word culture may make you think of a flag, style of clothing, celebration, or some other tradition associated with a particular group of people. But in biomedical science, a culture is a group of cells grown in a lab. Scientists use cultures to learn about basic biological processes and to develop and test new medicines. Credit: NIGMS. The Birth of a Culture Scientists can grow many types of cells as cultures, from bacteria to human cells. To create a culture, a researcher adds cells to a container such as a Petri dish along with a mix of nutrients the cells need to grow and divide. The exact recipe varies depe...

Klotho in the Pathology of Aging
Klotho is a longevity-associated protein; more of it slows aging, less of it accelerates aging, at least in animal studies. While researchers have spent considerable effort investigating the effects of klotho on the brain, as it improves cognitive function, it seems likely that its effects arise via improved kidney function in old age. Loss of kidney function, and thus clearance of metabolic toxins and waste from the bloodstream, is harmful to tissues throughout the body. Manipulation of klotho may be a good way to assess just how much harm is generated by the age-related decline of the kidneys. The subject of thi...

Fight Aging! Newsletter, August 8th 2022
In conclusion, aging research will benefit from a better definition of how specific regulators map onto age-dependent change, considered on a phenotype-by-phenotype basis. Resolving some of these key questions will shed more light on how tractable (or intractable) the biology of aging is. Does Acarbose Extend Life in Short Lived Species via Gut Microbiome Changes? https://www.fightaging.org/archives/2022/08/does-acarbose-extend-life-in-short-lived-species-via-gut-microbiome-changes/ Acarbose is one of a few diabetes medications shown to modestly slow aging in short-lived species. Researchers here take a ...

Are Pharmacological Approaches to Slow Aging in Fact Promising?
Today's open access review paper looks over a selection of what I would consider to be largely unpromising small molecules, each with evidence for their ability to slow aging, but very modestly and unreliably in most cases. Looking at the bigger picture, for much of the public it is still surprising to hear that the pace of aging can be adjusted via any form of therapy, so there is probably a role for simple, low-cost small molecule drugs in the process of education that leads to more serious efforts aimed at producing the means of human rejuvenation. Still, entirely too much effort is devoted towards small molecules that ...

In this study, we used the recently released Infinium Mouse Methylation BeadChip to compare such epigenetic modifications in C57BL/6 (B6) and DBA/2J (DBA) mice. We observed marked differences in age-associated DNA methylation in these commonly used inbred mouse strains, indicating that epigenetic clocks for one strain cannot be simply applied to other strains without further verification. Interestingly, the CpGs with highest age-correlation were still overlapping in B6 and DBA mice and included the genes Hsf4, Prima1, Aspa, and Wnt3a. Furthermore, Hsf4, Aspa, and Wnt3a revealed highly significant age-associated DNA methyla...

Aubrey de Grey on Progress in SENS Rejuvenation Research
In this recent interview with Aubrey de Grey touches on a number of areas of progress made by the research and development community in recent years, projects that lead towards rejuvenation therapies based on the Strategies for Engineered Negligible Senescence (SENS). In the SENS view, supported by a very sizable literature accumulated over the past century, aging is caused by underlying processes of damage accumulation. What we think of as aging is a diverse collection of downstream consequences of that damage. Periodically repairing the underlying damage, allowing the normal maintenance of the body to continue as it woul...

In conclusion, we show that PVS morphology in mice is variable and that the structure and function of pia suggests a previously unrecognized role in regulating CSF transport and amyloid clearance in aging and disease. Reversing Ovarian Fibrosis in Mice https://www.fightaging.org/archives/2022/07/reversing-ovarian-fibrosis-in-mice/ Researchers here provide evidence for ovarian fibrosis to be an important mechanism in limiting the age at which female mammals can remain fertile. Interestingly, existing antifibrotic drugs can produce some reversal of this fibrosis, enough to restore ovulation in mice. Fibros...

Discussing the Accelerated Aging of Cancer Survivors
It is well known that cancer survivors who underwent chemotherapy or radiotherapy exhibit a shorter life expectancy, greater chance of unrelated cancer incidence, and greater risk of age-related disease. The most reasonable hypothesis at present is that these undesirable outcomes are the result of an increased burden of senescent cells. Historically, cancer treatments have been in large part designed to force cancerous cells into senescence, those that are not killed outright by the therapy. Since these cancer therapies are toxic to cells, they also tend to cause off-target cell death and senescence. It is possible that si...

Fight Aging! Newsletter, July 11th 2022
In this study we employ a transcriptome-wide and multi-tissue approach to analyze the influence of both LTDR and short-term DR (STDR) at old age on the aging phenotype. We were able to characterize a common transcriptional gene network driving inflammaging in most of the analyzed tissues. This network is characterized by chromatin opening and upregulation in the transcription of innate immune system receptors and by activation of interferon signaling through interferon regulatory factors, inflammatory cytokines, and Stat1-mediated transcription. We also found that both DR interventions ameliorate this inflammaging phenotyp...
