Introduction to Young Plasma Infusions

Just to clarify for everyone what the phrase "young plasma infusions" refers to: 

Plasma is the water portion of blood in which blood cells are suspended. It includes salts, proteins, hormones, and many other non-cell components. 

The idea of transferring young plasma into older people for the purpose of rejuvenation is at least somewhat related to studies of parabiosis, which found that when an old mouse shares the circulatory system of a young mouse, the old mouse appears to get younger (and the young mouse appears to get older, by some measures). 

The thinking here is that there are components in the blood--possibly non-cell components such as hormones and signaling factors--that affect health and rejuvenation capacity. 

One way to replicate these possible positive effects of non-cell components of young blood is to infuse older people with plasma from younger people. Plasma donation and infusion are common and standardized medical procedures, so it does not need special development or approval like a new pharmaceutical does. 

At least one company is providing this service commercially: Ambrosia. As of this writing, their website is not functioning properly. 

It would be interesting to many members of this group if anyone receiving young plasma would share their experiences in this section of the forum. If you'd like to share your story, I invite you to click "start a new topic" on the right side of the forum page in this section.

    • Fred Cloud Pardon the very belated reply! (Notifications were not working for me.)

      I have actually had young plasma twice. Before/after results were not clear one way or another. In theory, it helped slow my aging at least a bit. But we need much more science to be done on this.

    • BrianMDelaney Oh wow. I see he is one of the ambrosia doctors. I didnt realize they had any on the east coast. So you paid $16,000 and didn't notice much? Well thats a bummer. My doc offered me the plasma but I did research and decided to go with gdf11 instead. I have been on it for 6 months and have had great gains from it.

    • Paul Beauchemin I agree, I wonder what the equivalent is versus whole plasma. Meaning, do you they pick a certain fraction and give you a large amount of that component that they extract from several liters of plasma? I know you cant just take gdf11 and concentrate it and give it as an injection all at once.

  • I'm assuming Paul you are referring to Josh Mitteldorf's "Age Reduction Breakthrough" article where he talks about Harold Katcher's plasma fraction treatment reducing the epigenetic age of multiple tissue. According to David Sinclair, if the findings hold up, "rejuvenation of the body may become commonplace within our lifetimes."

  • "Elixir" Resets Horvath's Clock

         This is the work being referred to above.  A preprint was recently placed on BioRXiv at https://www.biorxiv.org/content/10.1101/2020.05.07.082917v1 , authored by Steve Horvath, many others, and in particular Harold Katcher and Akshay Sanghavi, the founders of Nugenics Research of Mumbai, India  They report an experiment in which they use "Elixir", a Nugenics proprietary combination of active ingredients extracted from the blood plasma of young rats.  They administer Elixir to old rats, and observe the effects on various biomarkers of aging, including Horvath's famous DNA methylation profiles.  The results are spectacular, showing that the DNA methylation profiles were reset in age in various tissues ranging from liver to brain and other biomarkers showed similar results.  A popular account of the paper is available at Longevity Technology.

         I am very surprised by these results.  I had previously argued that periodic injections of young plasma could not be expected to do much because the active agents could only be resident in the recipient's bloodstream for a day or so, and any beneficial effect would be transitory at best.  These experimental results indicate that this is not the case.  The effects on rats last well after the treatment  period and seem to be permanent.  Therefore, I'm puzzled.  I don't understand the mechanism.

         I asked Harold Katchner about this.  He would only say that my assumptions were wrong, but implied that he was unable to explain why and how for trade-secret reasons.

         If anyone understands how brief exposure to the active agents in a derivative of young plasma can produce long-lasting effect, please explain it to me.

    • JGC Just guessing but it seems that there is a rejuvenating effect - repair of aged organs - and that is why there is a long lasting effect.

      JGC Its a great question what they are using or how this is working. Since they call it plasma fraction, it could be anything found in plasma and I don't think it is just plasma in naturally occurring ratios. If I had to guess I think they are using concentrations of plasma that gives high levels of components like gdf11 and maybe spiking it with exosomes.

      JGC There is a paper that explains tet enzymes role and the fact that dna demethylation occurs in a cyclical manner. Young plasma has tet enzymes and old one has less. What these guys did is most likely stumble on the number of times and frequency you need to apply young plasma in rats to cause demethylation. Basically it looks that due to biology of demethylation it doesn’t have to be a constant application. The next step as I see it would be to repeat it in marmosets and then we get closer to human applications. The exciting part is that with the same stone you can kill two birds- address the aging and cancer like breast and prostate too. Here is the paper http://genesdev.cshlp.org/content/30/7/733.full

      One can peer a bit behind the Elixir curtain.  Harold Katcher has commented that their Elixir does not contain GDF11, which is downstream from the effects they are producing. He also commented that ultimately the active ingredients in Elixir will be produced by chemical synthesis and will not need to be extracted from the blood plasma of young donors.

      Thanks, Joe.  I will ask Katcher to deny (as he did for GDF11) that the TET enzymes play a role in Elixir, and see what he says.

      Yes.  But he won't before they do animal tests.  Their plan is to get $50M of venture capital and set up a branch in California that rejuvenates dogs and cats.  They don't need FDA approval for that, just a cooperative vet.

      JGC Interesting. Well Josh said "Katcher is committed to bypassing the standard channel of Big Pharma, proceeding on his own with appropriate partners to assure that the the technology gets to a wide public at affordable prices" Why not set up in mexico or panama etc and offer it to humans? I say he should set up shop next to Dr Riordan at the stem cell institute in panama.

      JGC Seems so complicated and unnecessary. Why not bypass all of that and go offshore? There are alot of unproven therapies offered now like stem cells and people pay top dollar and flock to place like riordan in panama and pay $25k. So he actually should forget all the partners and funding and california regs. and set it up himself offshore and offer it to humans now and then create the study with the humans using it. He might need a million at most and he can be helping people sooner, cheaper and easier.

      JGC if you go https://twc-stanford.shinyapps.io/aging_plasma_proteome/ you can enter a gene/protein in the blood and see level of changes with aging. There is about 2925 proteins associated with aging captured in that database. The ones that you would want to promote, increase levels of, as there are much higher levels associated with young blood are growth differentiation factor 15 GDF15 and RET. The ones who you want to demote or decrease levels of are: SCARF2, SOST, ADP Ribosylation Factor Interacting Protein 2 (ARFIP2), PTN, IGDCC4, MLN, and CGA. The list is pretty exhaustive so whatever protein is in elixir is most likely captured by that database already. of Also GDF-11 levels are pretty constant with age so it doesn't look like it matters much. So what does he say about what is in elixir? If I were to experiment I would up the dose of promoters and filter out demoters and apply it to marmosets to properly establish dose and schedule.

  •      I just looked up the size of TET1, which is the smallest of the three TET proteins.  It has a mass of 80,000 Daltons (which we physicist call 80,000 AMU).  I think that's much too big to get past the cell wall, so I'm not sure that having it resident in the bloodstream would do anything.   A link to picture of TET1 is below.

         On the other hand, one can buy 10 micrograms of TET1 for $188.  Does anyone want to try shooting up some?

      JGC yeah tet proteins are actually very large ~180-230-kDa. What I was trying to say is that high 5hmC in young blood restores tet2, which in turn binds to dna and demethylates. See attached pic illustration.

  • Interesting point JGC, Is TET1 found circulating in plasma or does it just exist intracellularly? Because if it isn't found in plasma then would we be able to eliminate this as a possibility of the active ingredient in Elixir. (assuming Katcher is being forthright about this being a plasma fraction.)
