Towards Sensory Hair Cell Regeneration in the Inner Ear
Numerous forms of deafness, including age-related hearing loss, involve either loss of hair cells in the inner ear or loss of their axonal connections to the brain. These cells do not normally regenerate in mammals, and there is some interest in finding a way to bypass the suppression mechanisms that allow growth of hair cells during development but prevent regrowth during adult life. Approaches that show promise in animal studies include stem cell transplants, gene therapies, and small molecules targeting regulatory pathways. Here, researchers report on the ability of a mix of small molecules and siRNAs to produce regener...

Mitochondrially Targeted Lipid Nanoparticles as a Delivery System
This study reports on an attempt to establish a system for delivering an antioxidant molecule CoQ10 to mitochondria and the validation of its therapeutic efficacy in a model of acetaminophen liver injury caused by oxidative stress in mitochondria. A CoQ10-MITO-Porter, a mitochondrial targeting lipid nanoparticle (LNP) containing encapsulated CoQ10, was prepared using a microfluidic device. It was essential to include polyethylene glycol (PEG) in the lipid composition of this LNP to ensure stability of the CoQ10, since it is relatively insoluble in water.
Based on transmission electron microscope observations and sma...

In an Ideal World, How Much Would We Spend on Health Care? – Part 1
BY BEN WHEATLEY
We have heard it said before, and it is no longer shocking to say, that in 2021 the United States spent $4.3 trillion on health care. To put this gaudy number in some perspective, we measure it as a share of our economy and report that health care comprised 18.3% of our gross domestic product. CMS projects that health care will approach 20% of GDP in coming years—one-fifth of everything we buy and sell in this country.
In a recent report, the Health Affairs Council on Health Care Spending and Value said that “it is unclear what percentage of GDP would represent the ideal level to devote to healt...

In conclusion, NAT mitigated age-associated cerebral injury in mice through gut-brain axis. The findings provide novel evidence for the effect of NAT on anti-aging, and highlight the potential application of NAT as an effective intervention against age-related diseases.

Retinal Cell Reprogramming Restores Vision in Non-Human Primate Study
Early applications of in vivo cellular reprogramming to medicine are cautiously focused on retinal regeneration. The eye is as close to an isolated system as one is going to find in the body, and only small amounts of a gene therapy vector are required for effective delivery. This very localized, comparatively isolated therapy bypasses or minimizes many of the technical concerns and areas of uncertainty regarding reprogramming, allowing those who are focused on pushing applications to the clinical to forge ahead. The more interesting applications remain those in which reprogramming factors are delivered systemically to muc...

In conclusion, frailty progression accelerates in males with one LTCs and females with two LTCs or more. Health providers should be aware of planning a suitable intervention once the elderly have two or more health conditions.
Plasma Transfer Lowers Epigenetic Age and Mortality in Rats

Plasma transfer from young to old individuals has produced mixed results in animals and little to no benefit in humans where assessed rigorously. These studies were driven by the hypothesis that young plasma contains m...

Exercise and Alternative Mechanisms of Telomerase
Discussion on the canonical and extra-telomeric roles of telomerase are presented, followed by a detailed summary of the evidence on how exercise influences telomerase. Finally, the potential cell signalling underpinning the exercise-induced modulation of telomerase are discussed with directions for future research.

In conclusion, oral NR altered the gut microbiota in rats and mice, but not in humans. In addition, NR attenuated body fat mass gain in rats, and increased fat and energy absorption in the HFD context.

A Narrow Review on Progress Towards Gene Therapies to Treat Aging
There are a great many genes that one might target with gene therapies to treat aspects of aging. The review here is quite narrow in scope, and only looks at a few approaches to gene therapy, and a few of the genes that might be targeted, those that have arguably received more attention in this context and are either the subjects of small clinical trials or might be entering trials in the near future. It even omits follistatin and myostatin in favor of telomerase, klotho, VEGF, and APOE. The latter is probably not all that interesting as a target, but it is very well researched as a result of the strong focus on funding Al...

How Happy Cells Manufacture New Medications
This article focuses on the technology that ensures quality in the process, and is based on a conversation with Graziella Piras, PhD, Life Science Business Development Director at 908 Devices.
Traditional drugs are built from molecules synthesized chemically, combining the active ingredients with other substances that protect the molecules and ensure that they’re delivered to the right part of the body after being swallowed, injected, or otherwise applied.
Biotherapeutics, in contrast, are manufactured by living cells; sometimes the cells themselves are the drug. Biosimilars are just biotherapeutics that can replace ...

Towards An Aging Clock Based on Retinal Imaging of the Microvasculature
Blood vessel density declines with age, alongside other detrimental changes in the microvasculature, such as small areas of tissue damage following microbleeds. All of this can be readily imaged in the retina, and retinal imaging is already in widespread use in clinical practices. Thus it is interesting to see progress towards an aging clock that uses this aspect of degenerative aging as a marker. A number of potential therapeutic strategies may meaningfully increase angiogenesis and thus microvascular density in later life, such as increased circulating VEGF via gene therapy, or use of existing FDA-approved CLCX12 agonist...
