Chinese scientists say that children have made genetic immune to AIDS – Health – Life



A Chinese researcher informs the Associated Press (AP) that the & # 39; designed & # 39; has, from genetic modification, the first human being is immune to the AIDS virus (HIV).

This is Hy Jiankui, a researcher at the University of Shenzhen (China), said that he has the genetic editing tool CRISPR-cas9 (genetic sharpness) to change the embryos DNA of seven couplings that treat fertilizers.

Perhaps the DNA of these embryos is introduced (after biological surges of their DNA), the gene CCR5, which is two years, is said to protect against the AIDS virus, After it was found in a person who was rescued for the infection.

The changing embryos were taken in the hills of their biological mothers, clearing that they were two of them in one pregnancy, so it became known that two twillings would be the first beneficiaries of this progress.

While the scientific world waits for this information, the truth is that despite its potential, no independent confirmation of Jiankui's results; still the compulsory publication in a special magazine for her evaluation by peers in an academic context.

False expectations?

In addition to what it means, in theory, to stop the infection of HIV for the new generations, the ongoing anonymity created the moral debate that has always been involved with manipulation of embryos. Herman Esguerra, President of the National Academy of Medicine, affirms that nowadays does not have to be more than a personal opinion that should contain a scientific perspective before it is incorporated.

"It is very risky to fake expectations with something to be launched as AIDS, meanwhile, it is better not to comment on comment," says Esguerra.

As reported by Reuters, More than 100 scientists, most of them in China, called "madness" and opposite to ethics the change of human genes in an open letter that the Internet has squeezed. In addition, scientists have also said that the use of CRISPR-Cas9 technology to change the genes of human embryos was dangerous, unjustified and unplugged the reputation and development of the biomedical community in China.

"The biomedical etiological analysis of this so-called research only exists. Direct human experiments can only be considered as resistance"says the scientist in her letter, an instance published by the Chinese news website.

"The pandora's book is opened, we can still hope for hope to close it before it's too late, "said 120 scholars in text, written in Chinese.

The problem makes sensitivity to this kind of genetic editing in America – and in # 39; most countries are forbidden – to allow DNA changes to future generations to be handed over and there is a risk to other damage.

Cesar Burgos, President of the Colombian Association of Scientific Social Affairs, recalled that In Science, science speaks, and in that sense, it disappears from analysis based on a press message and not in serious scientific articles.

"If this is not published as it should be, it's nothing more than charlatanism," adds Burgos, the media also mentions what they publish in this context.

Paradoxes outside the power line, José Ernesto Vivas, expert in bioethics, is radically opposed to the many experiments that "eliminate the human condition and the candle of # designers on life's quality of a society with further interests mark of 'collective profit'. "It is unoriginal to think that the future generations have the characteristics that make a dominant elite," Vivas said.

China and lexicon in bioethics

The announcement has in the spotlight the lexicon of & # 39; The laws on biology in China. This country wants to become a world leader in research
Genetic and cloning, and the green areas of local legislation divided the way for controversial research.

In 2015 scientists Chinese were the first to kill the healing of human embryos, according to the journal Nat. In the same period, a laboratory was built in Tianjin (north) to cling to clergy, with the ambition to make up to 1 million cows in the year. Beginning 2018 researchers Chinese managed the genetic identical monkeys for the first time, with the same cloning technique used more than 20 years ago with the famous sheep Dolly, the first cloned scent animal.

According to Qiu Renzong, pioneer of biological problems in China, The researchers are not confused, to give only their accounts to their institution. Some of these institutions do not deserve a penalty in favor of professional speed. "China protects scientists a lot, if we make a minor mistake, it remains there, there are no sanctions," he said in Hong Kong on the side of an international congress

And more than lucal laws or in other countries, China would lead to a biomedical sector, donated Michael Donovan, founder of Veraptus, a biotechnology company in that country. Other factors affect, such as demographics. The 1.400 million residents guarantee the country a major problem of potential patients, it is suitable.

On the other hand, the pressure of religious groups is not feasible, as well as the United States, "but when it comes to life, people are the same way as they are very fast." "It seems like China has no moral limitations to the prevention of such research," said Fang Gang, a professor of biology at New York University in Shanghai.

For now, the National Health Commission, which has the rank of the Ministry, ordered an investigation into the case en Vice Minister of Science and Technology, Xu Nanping, He pointed out that when the twin was really born, he would be illegal, According to the ethical principles found in 2003, research on embryonic organs, may be possible in vitro culture, but only for 14 days after fertilization or nuclear transplantation.
