30th June 2025 Newsletter
Hi guys. This is the sixth newsletter from the Institute of Rejuvenation Science (ICR). In these newsletters, we will tell you what we've done, since the last newsletter, to accelerate the development of rejuvenation science.
Poster presentation at the Extracellular Vesicles 2025 symposium in Paris
Poster presented at the Extracellular Vesicles 2025 symposium in Paris (France) on the 26th of June, 2025
On the 26th of June 2025, the scientific research carried out by the ICR was presented at the Extracellular Vesicles 2025 symposium in Paris (France) through a poster exhibition. It described the experiment carried out by the ICR in 2024, with the participation of Unicamp, in which we injected Pig Plasma Extracellular Particles (PPEPs) from young animals into young rats, to assess acute immunogenicity and toxicity (by the way, without any of these problems being observed). Our scientific article was accepted by the European Journal of Biological Research. In addition, we also described in the poster the experiment we will be carrying out in June 2026, when we will inject the PPEPs from young animals into old rats to rejuvenate them, as well as injecting them into young rats to see if it is possible to keep them young. This experiment is being carried out in partnership with DoNotAge.org, Heales, and all the other donors. In fact, it was Heales who exhibited the poster at this symposium in Paris.
The ICR in the media
On the 3rd of June, 2025, LongeCity, an organization focused on the development of the science of rejuvenation, published a podcast interview with us (Nicolás and Nina) about the reproduction of Harold Katcher's seminal rat rejuvenation experiment, to be carried out by the ICR in collaboration with Unicamp.

Raised funds reach 70.6% of the total
By the end of June 2025, the ICR has already raised 70.6% of the total needed to carry out the experiment to rejuvenate rats with PPEPs. This brings the total raised to US$ 52,950, with the remaining 29.4% still to be raised to reach the total of US$75,000. The ICR is contacting as many players in the field of rejuvenation science as possible to inform them about the experiment and the possibility of donations. In addition, we are looking for specialized media that may be interested in publicizing our initiative. So, if you know of a YouTube channel, podcast, newspaper or other media outlet that might be interested in publicizing this experiment, feel free to talk to us about it or directly to the media outlet.
Our president Nicolás Cherñavsky explains in a video what aging is and how to reverse it
During this month of June 2025, the president of the ICR, Nicolás Cherñavsky, published a video in which he explains what, in his view, aging is, and how to reverse it. The reason for publishing this video is to show that there is a coherent scientific theory that explains the existence of aging, as well as a concrete plan to reverse it, which can make people realize that the existence of aging is not a losing battle, but something they can get involved in to speed up the arrival of rejuvenation. You can watch the video by clicking here. If you think it's a good idea, you can share the video with friends, family and acquaintances. The video is in Portuguese, but by activating the simultaneous translation feature of YouTube's subtitles, you can understand almost everything. It's important to remember that in addition to YouTube, ICR publishes content and updates on two other social networks, Instagram and LinkedIn.
This is a collective effort
This experiment is a collective effort to reproduce Harold Katcher's seminal study, in which the ICR relies on the contribution of those interested in the realization of the experiment. Thus, if you know someone who might be interested in the content of this newsletter, you can forward it to them. Also, if you are not yet a financial contributor of the ICR, we invite you to become one by clicking on this link.
So that's it. We're carrying on, and we won't rest until we've implemented rejuvenation in human beings. See you next time!
