2779.2671 Eternal Youth (Lower) (Alliance Leader V Heaven V Additional Chapter 3)

"Really useful?" Zhou Litao had only heard various rumors before, saying that in some place, an elderly person once went to do experiments to earn money, regularly exchanging blood. Later he discovered that he rarely got sick and seemed younger than his peers, etc.

The rumor said that after the experiment ended, that old man still sought to regularly exchange young people's blood to maintain this state.

At that time, hearing it, Zhou Litao just laughed it off, thinking this was basically just folk legend, fiction, etc.

But Zheng Lao Ban said the related experimental results were published in top-tier journals like Nature, which makes it interesting.

"TonyWyss-Coray collected the blood of young mice and transfused it into old mice. Five weeks later, the old mice that received the blood showed significant changes in the brain. Their learning ability, environmental adaptability, and memory improved, and even their physical strength increased."

"He later conducted human trials, which caused a big controversy, and I don't know whether he gave up or did it secretly." Zheng Ren said, "However, TonyWyss-Coray ultimately believed that some component in the blood is linked to bodily aging. In the future, we might be able to extract these substances from blood, develop anti-aging drugs, and extend human lifespan."

"Zheng Lao Ban, this thing... can we actually do it?" Zhou Litao's eyes changed.

Zheng Ren shook his head slightly, saying, "We can only say that, without full verification, we temporarily do not recommend it; besides blood exchange, there's also so-called blood cleansing, which we also do not recommend because the project is immature and the risk is relatively high."

"Ah?"

"Limited type? In any era, any dynasty, any person will have a certain limitation." Zheng Ren laughed and said.

"You could just tell him that not few emperors throughout history died from alchemy; no need to make it so complicated." Su Yun said.

"That's pretty much the meaning." Zheng Ren said, "Without long-term, large-scale experimental samples, we still can't confirm whether it's effective. Moreover, we don't know if blood exchange has any side effects, or whether it will change personality."

"Change personality?" Zhou Litao jumped in fright.

"Don't listen to his nonsense; bone marrow transplantation does have similar cases proving DNA changes. Blood exchange causing personality change has never been heard of." Su Yun said.

"That's because current research is insufficient, or perhaps it's being kept secret. Similar to Bota Laboratory, not all results need to be first published in top-tier journals." Zheng Ren said.

"What you're saying has nothing to do with it. Manager Zhou, don't listen to the boss's nonsense; at least with the current limited samples, there appear to be no side effects." Su Yun argued.

Zhou Litao swallowed a mouthful of saliva, wondering if this were feasible, could human lifespan be greatly extended in the future?

"As for the theoretical foundation, we have to go back to a very old experiment, almost 200 years old." Zheng Ren said, "Heterospecific symbiosis, have you heard of it?"

Zhou Litao shook his head.

Su Yun said, "When I was performing heart transplant surgery on mice, I wanted to try it, but I didn't get the chance before returning to Hai Cheng."

"Heterospecific? Symbiosis?" Zhou Litao was a bit doubtful, wondering if there wasn't any rejection reaction.

"Heterospecific symbiosis is connecting two animals with different traits and states together, letting them share a common bloodstream, to study which substance in the blood affects health."

"This has been around for nearly 200 years, with no definitive conclusion yet. The earliest model was developed in 1864 by French zoologist PaulBert to study shared circulation: the sides of two mice are cut open, then their skin and muscle walls are sewn together, to study the interactions produced between different animals via blood circulation."

"Cut open, different mice sharing blood... Zhou Litao immediately felt this was something those mad scientists would come up with."

"Black technology, ruling the world—those clichéd plots in bloody movies and TV shows filled Zhou Litao's mind."

"Heterospecific symbiosis once provided the theoretical basis for finding leptin." Zheng Ren said, "The two connected mice, the fat one quickly became thin. Leptin, this chemical substance, was discovered in this way."

"Zheng Lao Ban, wasn't that mouse thin from starvation?" Zhou Litao asked.

"Hahaha, Manager Zhou, your question is really sharp." Su Yun laughed loudly.

Zhou Litao immediately realized that Zheng Lao Ban had said this experiment provided the theoretical basis for finding leptin, so it definitely wasn't due to starvation.

"The discovery of leptin earned Coleman and Friedman the 2010 Lasker Award together." Zheng Ren said, "But it doesn't work in humans. Now many people claim leptin can reduce weight, yet there's no theoretical basis."

Su Yun raised her eyebrows, her boss having gone on a big circle, ultimately returning to one theme—animal research results cannot be realized in humans, leptin being a typical example of this theory.

"This person is truly narrow-minded," Su Yun thought disdainfully, glancing at her own boss.

"Using the decomposition method of basic experiments, scientists mainly identified four functionally distinct protein molecules: CCL11, GDF11, TIMP2, and VCAM1. However, there is still much debate about their functions."

"Some substances not only fail to bring benefits to people, but actually cause greater harm."

"Boss, if you were as conservative as you are, penicillin wouldn't exist. Hurry back to live in a cave and go hunting every day, okay?" Su Yun said disparagingly.

"I'm just saying that blood exchange, which lacks certainty, doesn't involve what you mentioned." Zheng Ren said, "Getting back to the topic, glutathione is actually a rather interesting drug. Many drug trials have proven it indeed has an effect on delaying aging."

"Really!" Zhou Litao's eyes lit up.

"Who knows." Zheng Ren began to speak irresponsibly, saying casually, "No matter what, it's just a guess; the related pharmacological trials are still being further studied. Teacher Tu spent many years researching before extracting artemisinin from sweet wormwood."

"I think glutathione's effect is limited; if we truly want to stay youthful, we should start research from young people's blood." Su Yun said firmly, "The mouse experiments have already achieved some effect; next we need to do human trials."

"Don't talk nonsense." Zheng Ren stubbed out his cigarette, chuckling, "Go take a look at Cui Lao, then go home and eat."

Su Yun seemed to still have much to say, but talking more about this would just be speculation. Ancient emperors held the highest-end resources of their time, yet they never imagined that pill after pill of elixirs would become poison that brings death.

Heavy metal poisoning, which now seems unavoidable, was actually eagerly taken by emperors and officials; thinking about it, it has a somewhat suicidal connotation.
