@NextScience Extracellular reHMGB1 → macrophage activation/inflammation via the SASP → increased CD38 expression → NAD⁺ depletion → further senescence This mechanism enables the systemic propagation of senescence, creating a self-sustaining loop of inflammaging

🚨 Scientists found a protein that carries "old age signals" through the body — and blocking it literally reversed the damage. In a major breakthrough in aging research, scientists at Korea University’s College of Medicine have discovered that cellular aging can spread throughout the body via the bloodstream. The culprit is ReHMGB1, a redox-sensitive version of a protein called HMGB1, which is secreted by aging, or senescent, cells. This protein was shown to trigger aging-like effects in distant, healthy tissues—reducing their ability to regenerate and harming muscle performance. In mouse models, researchers successfully blocked ReHMGB1 using antibodies, resulting in fewer signs of aging and improved recovery after injury. This study, published in Metabolism – Clinical and Experimental, provides the first direct evidence that aging is not just a local cellular process but one that can be systemically transmitted through blood. By identifying ReHMGB1 as a key molecular messenger in this process, researchers now have a potential target for therapies aimed at slowing or even reversing age-related decline. The findings could have far-reaching implications for treating a range of conditions tied to aging, from muscle wasting to organ degeneration. Source: Jeon, O. H., et al. (2025). Propagation of senescent phenotypes by extracellular HMGB1 is dependent on its redox state. Metabolism – Clinical and Experimental.

@bryan_johnson This is true. If you want to live longer and healthier, master inflammaging before it masters you. Here’s why it starts, how it spirals and the chronobiological tools used by our cells to control it.

Proud of this one: no detectable systemic inflammation in my body across three consecutive tests in 30 days. Inflammation is a killer. Achieving this requires perfection of nutrition, sleep, stress management, exercise and life systems. For those of you who love this stuff but find the logistics and know how hard. I'm building the systems for you. Coming soon.

Today, some 45M deaths a year owe to biological aging, and we treat these deaths as mostly inevitable. But what if they are not? What if preventing our newly slow deaths is a moral and economic imperative? In my @TEDx talk, I suggest progress in aging bio may offer the highest social return of all possible investments in biomedical research. Aging science could soon make for the most impactful breakthroughs in human history, exceeding the impacts of germ theory and antibiotics in redesigning how we live and die. If we truly reverse biological aging, we’ll add trillions to GDP—and more meaning to life. youtube.com/watch?v=kB1IFG…

When NAD+ crashes, the ancient mitochondrial endosymbiosis breaks down — the cell falls back into "archaea mode". Then start the diseases. #citeas" target="_blank" rel="nofollow noopener">nature.com/articles/s4158…
William A. Wallace, Ph.D.@WilliamWallace

Mitochondria are not just power plants. They are decision-makers. They regulate inflammation, aging, and disease. A quick breakdown: 🔵 Energy signaling, not just energy production Mitochondria don’t just make energy. They decide how energy is produced, where it’s used, and when cells change their behavior. Energy itself acts as a signal that tells cells what to do. 🟣 Inflammation control When mitochondria are damaged, they release internal components into the cell. The immune system interprets these as danger signals and turns inflammation on, even without infection. 🟡 Aging regulation As we age, cells become worse at clearing damaged mitochondria. These dysfunctional mitochondria build up, increasing oxidative damage and low-grade inflammation that drives aging. 🟢 Why many diseases look different but share the same root Neurodegenerative disease, heart disease, diabetes, obesity, autoimmune disease, sepsis, and cancer all involve failure of mitochondrial function. Different organs. Same underlying problem. 🟠 Why “antioxidants” alone miss the point The problem isn’t just damage. It’s where the damage happens, why it happens, and whether the cell can remove the broken machinery afterward. 🔴 Why this changes how we think about health You don’t treat dozens of unrelated diseases separately. You support mitochondrial health—and multiple systems improve together. What this all means: • Mitochondria are control centers, not batteries • Inflammation often starts as an energy problem • Aging reflects declining cellular maintenance • Many diseases are the same biology showing up in different tissues Health isn’t just chemistry. It’s how cells manage energy. And mitochondria sit at the center of the system. Doi:10.1038/s41392-025-02253-4

The effect of obesity and aging on NAD+/Sirtuin metabolism transcription and DNA methylation in subcutaneous adipose tissue of monozygotic twin pairs discordant for BMI "Impaired NAD+/SIRT metabolism in AT may play a key role in obesity- and aging-related diseases. Both conditions are characterized by downregulation of NAD+/SIRT pathway genes, correlating with increased adiposity, insulin resistance, inflammation, and dyslipidemia. Obesity uniquely disrupts expression of NAD+/SIRT regulated mitochondrial genes, while aging is characterized by altered PARP expression, particularly increased PARP1, likely exacerbating metabolic dysfunction in AT." nature.com/articles/s4136…

@SunWeatherMan The fifth and, in my opinion, the most important is magnesium. Whitout it, it is impossible to get nmn converted into nad+. When NAD+ crashes, the ancient mitochondrial endosymbiosis breaks down into "archaea mode" x.com/i/status/20058…

The golden triangle of looking younger just became a quad-stack. Collagen Red light Lymphatic drain And now, NMN for NAD Holy shit. Trainer noticed and we asked randoms my age… average was 32. Im 41, and looked it a decade ago. Recommend dissolve-under-tongue lozenges.

Never get Alzheimer’s Disease: The NAD+ Breakthrough 1/9) This graph hints at a potential breakthrough in Alzheimer’s disease. It shows that NAD+, a key energy carrier in the brain, is depleted in Alzheimer’s—but preserved in cognitively healthy brains. Restoring it may not just protect memory—it might reverse dementia.
