Psilocybin, the principle psychoactive ingredient in magic mushrooms, extends the lifespan of human cells, a lab examine suggests. Researchers additionally discovered that the psychedelic compound slows sure hallmarks of getting old in older mice whereas enhancing their fur high quality.
The findings, revealed July 8 within the journal npj Ageing, present the primary experimental proof of psilocybin’s potential anti-aging properties.
“The examine supplies a singular have a look at the potential of psychedelics to advertise wholesome getting old and supplies a provocative mechanism to clarify how they do it,” Scott Thompson, a professor within the College of Colorado Division of Psychiatry who was not concerned within the analysis, advised Reside Science in an electronic mail.
Nevertheless, “a lot extra work shall be required to take these findings ahead in a method that may reveal whether or not or not the findings are relevant and adaptable for human well being,” Thompson stated.
Just lately, research have explored psilocybin’s therapeutic potential for treating numerous circumstances, equivalent to anxiousness, melancholy and neurodegenerative problems like Alzheimer’s illness. A few of this analysis has led to scientific trials with promising outcomes. However researchers have not but pinned down precisely how the psychedelic achieves its advantages.
One idea, dubbed the “psilocybin-telomere speculation,” proposes that psilocybin preserves the size of telomeres, the protecting caps of repetitive DNA sequences positioned on the ends of chromosomes. Researchers have lengthy understood that telomeres shorten with age, and the speed of that shortening correlates to the speed of getting old.

So if psilocybin protects telomere size, might it additionally delay getting old?
To search out out, examine senior creator Dr. Louise Hecker, an affiliate professor at Baylor Faculty of Drugs in Houston, and colleagues administered completely different doses of psilocin, which psilocybin will get damaged down into within the physique, to remoted human lung and pores and skin cells. The workforce discovered that the psilocin prolonged the lifespans of the cells by as much as 57%, relying on the dose given.
The psilocin additionally preserved the cells’ telomere size and decreased ranges of oxidative stress, or the buildup of reactive molecules. Concurrently, it led to greater ranges of Sirt1, a protein related to longevity.
In brief, the psilocin made the cells appear as if youthful cells, Hecker advised Reside Science. Hecker’s analysis includes trying on the impacts of getting old on the physique, and the whole lot she knew to check for “simply labored” she stated. “I used to be floored by the information.”
The workforce then went on to check the consequences of psilocybin on roughly 19-month-old feminine mice — which, in human years, can be of their early 60s. The mice acquired month-to-month doses of psilocybin for 10 months. On the finish of that interval, 80% of the handled mice had been nonetheless alive, in contrast with solely 50% of an untreated group. The handled mice additionally displayed hair development the place they’d beforehand had bald spots, and their once-white hair grew again brown.
“It is thrilling that we may give this intervention in late life and have such a dramatic affect,” Hecker stated.
Psychedelics, usually, are identified to alter the workings of the immune system and the physique’s stress resilience, each of which might have an effect on organ well being, Thompson stated. “What’s new on this examine is the provocative suggestion that adjustments within the size of telomeres — necessary regulators of DNA replication — could also be produced by psychedelics.”
A significant limitation of the examine is that the drug doses used within the lab mice are a lot greater than these sometimes administered to people, Thompson stated. That stated, Hecker argues that this comparability would not think about the a lot sooner metabolism of mice and the consequently shortened time the psychedelics are lively within the animals.
The findings set the stage for investigating psilocybin as a remedy for getting old and age-related ailments, Hecker stated. Future analysis ought to examine optimum doses to make use of in people, in addition to the potential dangers, she stated.
