Reviewing the Development of Senotherapeutics
Today's open access paper is a very readable tour of the present state of research and development of therapies targeting senescent cells, whether to destroy them or alter their function in favorable ways. In both cases the primary goal is to reduce the senescence-associated secretory phenotype (SASP), the pro-growth, pro-inflammatory signaling that contributes to degenerative aging as the number of senescent cells rises over the course of later life. It is hoped that clearance of senescent cells will produce a sizable positive impact for late life health, reducing chronic inflammation, slowing the onset of near all age-re...

In conclusion, our study reveals that aging enhances atherosclerosis via increased inflammation of visceral fat. Our study suggests that future therapies targeting the visceral fat may reduce atherosclerosis diseaseburden in the expanding older population.

Towards Microneedle Delivery of LNP-mRNA Gene Therapies for Skin Aging
The skin is arguably one of the easiest of the large organs in the body to target for delivery of gene therapies, via established microneedle approaches. Nonetheless, much of the initial thrust of gene therapy clinical development focused instead on the liver, one of the other more tractable targets. Most material injected into the bloodstream ends up in the liver, and a single injection is logistically easier than coverage of large amounts of skin via microneedle patches, among other reasons. Given the advent of messenger RNA (mRNA) encapsulated in lipid nanoparticles (either artificial or repurposed extracellular ...

This study explored the association between tap drinking water and longevity in Cilento, Italy, to understand whether trace elements in local drinking water may have an influence on old, nonagenarian, and centenarian people and promote their health and longevity. Data on population and water sources were collected through the National Demographic Statistics, the Cilento Municipal Archives, and the Cilento Integrated Water Service. Ordinary least squares (OLS) regression and a geographically weight regression (GWR) model were used to study the spatial relationship between the explanatory and outcome variables of long...

Conclusions Implanted Hair Follicle Cells Produce Remodeling of Scar Tissue Assessment of Somatic Mosaicism as a Biomarker of Aging The Gut Microbiome of Centenarians https://www.fightaging.org/archives/2023/01/the-gut-microbiome-of-centenarians/ The state of the gut microbiome is arguably as influential on health as exercise. Various microbial species present in the gut produce beneficial metabolites, such as butyrate, or harmful metabolites, such as isoamylamine, or can provoke chronic inflammation in a variety of ways. An individual can have a better or worse microbiome, assessing these and other...

Implanted Hair Follicle Cells Produce Remodeling of Scar Tissue
Researchers here report on an interesting approach to treating scar tissue in skin. Noting that hair follicles appear to promote regeneration in healthy skin, they implant follicles into scar tissue. The result is some degree of beneficial remodeling of the scar. While the next logical step is to better understand the signaling involved in this effect, it is worth noting that researchers have been attempting to understand the mechanisms of skin regeneration for some time now. It is a very complex situation involving many different cell types, structures, and phases of activity that change over time. There is unlikely to be...

Commentary on More Drastic Scenarios of Partial Brain and Full Body Replacement
Is outright replacement of tissues a viable option for the treatment of aging? There are factions within the longevity-interested community who think that the paths to either (a) engineering replacement brain tissue for parts of the brain not involved in memory, or (b) transplantation of an old head onto a young body or brain into a young body, are short enough to be worth pursuing, where "short enough" means a few decades of work given sufficient funding. To my mind, major surgery of the sort implied by replacement of large sections of tissue or entire organs is something to be avoided in later life, given the risks and c...

Extracellular Mitochondria Have Some Ability to Selectively Target Tissues Experiencing Mitochondrial Dysfunction
Mitochondria can be ejected and taken up by cells, or transferred via connections between cells, and this appears to one of the many ways in which cells communicate or attempt to assist in cases of damage. It is of great interest to the research community that intracellular mitochondria can be taken up and used by cells, given the existence of inherited diseases resulting from mitochondrial mutations, and given the late life decline in mitochondrial function that contributes to many age-related conditions. It may be possible to deliver fully functional mitochondria as a therapy, to be ingested by cells in order to repair t...

A Look Back at 2022: Progress Towards the Treatment of Aging as a Medical Condition
At the end of 2022, we can reflect on the fact that we are steadily entering a new era of medicine, one in which mechanisms of aging are targeted rather than ignored. It is a profound change, one that will change the shape of a human life and ultimately the human condition by eliminating the greatest sources of suffering and death in the world. Year after year, we see increased funding, ongoing progress towards therapies capable of slowing aging or reversing aspects of aging, and a growing taxonomy of such potential therapies and their target mechanisms. The view of aging in the medical community and public at large...

A High Level Survey of Mechanisms of Brain Aging
Ultimately, we live and die as the brain lives and dies. The rest of the body is a support system, a complex one to be sure, but probably not as complex as the brain. Repairing the cell and tissue damage of aging in the body seems a more tractable challenge, in that replacement is always an option. Replace cells, replace the gut microbiome, add new tissues grown in a lab to organs like the liver and thymus, or grow a new body and transplant the brain. A path of ever increasing control over cells, cell signaling, and regeneration implies a future in which all damaged tissue can be replaced in one way or another ... except f...
