A Look Back at 2023: Progress Towards the Treatment of Aging as a Medical Condition
The market has been in the doldrums and it has been a tough year for fundraising, both for non-profits and biotech startups. The conferences have exhibited more of an academic focus as companies tightened belts and postponed investment rounds, while investors stayed home. Not that this halts the flow of hype for some projects, and nor has it slowed media commentary on the longevity industry as it presently stands. A few of the articles in that commmentary are even interesting to read! The field has grown and is more mature now than has ever been the case. Biotech of all forms is a challenging field with a high failure rate...

Reviewing What is Known of the Mechanisms of Taurine Supplementation Relevant to Aging and Metabolism
Taurine is a semi-essential amino acid. Dietary taurine supplementation has been shown to modestly slow aging in mice, though as for all such interventions there is always the question of whether it will prove to be less useful in humans, and also whether these results in mice will be disproved by the much more rigorous Interventions Testing Program (ITP), once that group gets around to assessing taurine supplementation. Few of the numerous interventions thought to modestly slow aging in mice on the basis of earlier research actually held up once subjected to the ITP degree of experimental rigor.
Speculatively, taur...

Towards Adjustment of the Gut Microbiome to Slow Aging
This paper makes the reasonable argument that means of modestly slowing aging will emerge from ways to reverse age-related changes in the varied microbial populations making up the gut microbiome. The gut microbiome changes with age, in ways that provoke chronic inflammation while also diminishing the supply of metabolites necessary for tissue function. Given the evidence generated from human and animal studies over the past decade, it is reasonable to think that the gut microbiome has as much influence on the course of long-term health as lifestyle choices relating to diet and exercise.
Aging is a complex natural...

Fight Aging! Newsletter, December 25th 2023
This study generates a comprehensive single-cell transcriptomic atlas of human atherosclerosis including 118,578 high-quality cells from atherosclerotic coronary and carotid arteries. By performing systematic benchmarking of integration methods, we mitigated data overcorrection while separating major cell lineages. Notably, we define cell subtypes that have not been previously identified from individual human atherosclerosis scRNA-seq studies.
Besides characterizing granular cell-type diversity and communication, we leverage this atlas to provide insights into smooth muscle cell (SMC) modulation. We integrate genome...

Induction of Autophagy Slows High Fat Diet Induced Atherosclerosis in Mice
Atherosclerosis is the name given to the growth of fatty lesions in blood vessel walls, narrowing and weakening blood vessels, and eventually rupturing to cause a heart attack or stroke. This is the primary cause of human mortality. Many approaches have been demonstrated to slow the progression of atherosclerosis in the most commonly used mouse models, in which atherosclerosis is rapidly induced by a combination of high fat diet and the disabling of genes, such as APOE and LDLR, that are important to maintain normal blood cholesterol levels and cholesterol transport. Very few approaches have been shown to produce a reducti...

Existing Geroprotective Drugs May Not Interact Well with Exercise
The big disadvantage of the geroprotective approach to aging, which is essentially to undertake the long-term use of supplements and small molecule drugs to alter metabolism in ways that slow aging over years and decades, is that distinct supplements and small molecules and adjustments tend to combine in unexpected ways. Short of testing every combination in laboratory species, something that Brian Kennedy's team has been working on, one can never know the outcome of combining a treatment. Based on presentations and interviews given by Kennedy in the last few years, the result of combining two geroprotectors that individua...

Season Health Announces Strategic Asset Acquisition from Wellory to Expand Clinical Network of Registered Dietitians and Insurance Coverage
Season Health, the leading integrated food-as-medicine platform, today announced the closing of a strategic acquisition of clinical assets from Wellory, one of the largest networks of registered dietitians in the country providing medical nutrition therapy to patients nationwide. This accelerates Season’s growth by significantly expanding its provider network and its ability to offer comprehensive, personalized nutrition care to more patients, including those looking for in-network benefits.
Since its founding in 2019 by Emily Hochman and Jeni Fahy, Wellory has focused on unlocking access to quality nutrition care se...

Inflammaging in the Inner Ear, a Path to Hearing Loss
Inflammaging is a blanket term for the inappropriate inflammatory reaction of the immune system to the accumulation of molecular damage and other changes that take place with age. Constant, low-grade, unresolved inflammatory activation of the immune system is a feature of aging. It alters cell behavior for the worse and is disruptive to tissue structure and function. A number of different mechanisms contribute to forming and maintaining the state of inflammaging, such as pro-inflammatory signaling produced by ever-larger numbers of senescent cells, and innate immune recognition of mislocalized mitochondrial DNA that result...

How to Measure Healthspan in Mice
Somewhere in the list of topics that are not given a great deal of thought outside the research community, there is the issue of how exactly one goes about measuring healthspan in mice, the length of life spent in good health. There is no standardization to speak of, and what is called healthspan in one study is typically assessed with a completely different set of measures from what is called healthspan in another study. Thus there are groups attempting to promote specific well-defined approaches to assessment of healthspan in animal models, in the hope that others adopt them in order to make data on the effects of interv...

Reviewing the Contributions of Circadian Rhythm Dysfunction and Dysbiosis to Blood-Brain Barrier Leakage
The blood-brain barrier is a layer of specialized cells wrapping blood vessels that pass through the brain. Only certain molecules and cells are admitted. The metabolism of the brain is thus isolated from that of the rest of the body. In particular, the immune system of the brain is quite different from that of the rest of the body. Unfortunately, this isolation is a vulnerability when, like all biological systems, the blood-brain barrier begins to break down and leak. The leakage of inappropriate molecules and cells into the brain provokes inflammation and dysfunction, and this is likely a contributing factor in the devel...

In conclusion, given the relative safety and the favourable effects of aspirin, its use in cancer seems justified, and ethical implications of this imply that cancer patients should be informed of the present evidence and encouraged to raise the topic with their healthcare team.

Ozempic: miracle drug or a band-aid for obesity?
An excerpt from Dr. T’s Drop the Fat Diet: 12 Steps to Leaner You Forever. Semaglutide, a medication often marketed as Ozempic, Wegovy, or Rybelsus, has gained immense popularity in recent years. This is especially true in an age where diabetes and obesity are on the rise. The medication is being seen as a panacea

Changes in the Gut Microbiome Correlate with Aging and Renal Function
The gut microbiome changes with age. Pro-inflammatory microbial populations grow in size at the expense of populations that produce beneficial metabolites. As researchers produce increasingly large databases of the composition of the gut microbiome across ages and populations, they are also mapping a growing number of specific connections between microbial species and aspects of aging. Some of this work shows causation, but most human data can only show correlations between aspects of the gut microbiome and aspects of aging. In today's open access paper, the authors focused on finding links between the gut microbiome and t...
