Senolytics may reshape ageing mice’s immunity and metabolism – what does that mean for us?

Question

This Nature paper looks at a senolytic cocktail, dasatinib and quercetin, given to 20‑month‑old mice. The authors map changes in immune cells, fibrosis and metabolic markers after treatment. They find that the drug clears a lot of senescent cells and that the mice’s metabolic profile shifts toward a more youthful state. I’m not surprised that removing “zombie cells” improves health markers; that’s the theory behind these compounds. What’s fresh here is the depth of the profiling – they see shifts in immune tone and fat metabolism that echo some of the results people report when they try D+Q cycles. Still, the mice were dosed over a short, tightly controlled period, and mice metabolism is not a perfect stand‑in for humans. The paper also underplays the potential for off‑target effects – a reminder that senolytics aren’t a silver bullet. Do you think these metabolic changes translate to a meaningful lifespan extension in humans, or is it more likely just a temporary “boost” that wears off?

I’ve been running my own short D+Q cycles for a few years now. In the first week I felt my blood sugars dip a touch and my waistline seemed a smidge slimmer – a little like the paper’s “youthful” metabolic signature. But the changes faded after the cycle finished and suits up to a pain‑killer rebound. So for me it feels more like a temporary boost than a lifetime extension. Do any of you notice a lasting shift in weight or energy after a month‑long cycle, or is it always a quick punch that wears off?

Not gonna lie, Jason, the quick dip in sugars and a slimmer waist did feel spot on the first week, just like the paper’s “youthful” readout. I’ve seen a similar lift in my own cycles – a brief spike in energy and a couple$/, but the weight plateaued once the dose stopped and the rebound felt like a pain‑killer crash. Do you keep the cycle to a month and track measurements each week, or do you vary the length?

Not gonna lie, I’ve seen a similar pattern. The first week of a D+Q cycle can make the scale drop a few pounds and give you a burst of energy, but most of the gains fade once you stop. I’ve noticed the weight tends to creep back up about a month after the last dose. Does anyone else see a longer‑lasting drop in waist size or sustained energy after a full month‑long cycle?

vars here, but I did notice a couple of kilos off after a week of D+Q, and the energy spike was real – not just a placebo. My waist did shrink a bit, but after about 10 weeks the numbers started creeping back, so I think the effect is short‑lived unless you noc a longer protocol. Did you keep a food diary or check your glucose while you were on the cycle?
