The case of genetic modified twin causes international changes: they will never have HIV

Conflict and doubt, that is the reaction to the announcement that a Chinese scientist launched the first genetically modified children's books in # 39; the world would be created for certain diseases by using the CRISPR gene editing tech.

The controversy started then specialized publications such as the American magazine MIT Technology Review studying scientists He Jiankui, who has youtube recorded yesterday on youtube where he claims that healing twins have changed.

According to the Chinese researchers, the girls, Lulu and Nana "have been born many weeks ago," by in vitro fertilization with genetic modification technology, "they come to HIV infection."

In this video, it seeks to use the CRISPR / Cas9 technique and focuses on the experiment that indicates that genetic modification "does not do to prevent genetic disease" but rather to give "girls the natural capability of a possible future HIV infection. "

To achieve its purpose, it claims that the CCR5 has "deactivated," which offers many causes the virus to prevent a cell and that in practice an improvement of DNA.

"I understand that my work is controversial, but I think families need this technology and I'm ready to criticize them," he says in one of the video's.

The University of Science and Technology of & nbsp; The southern city of Shenzhen city today asserts its professor in a statement and stated that he was not aware of this project.

The institution said that the "was seriously injured by the case" and calls on February, as early as February, as soon as possible to give explications.

"The university invites international experts to investigate this event, which is a serious wound of ethics and academic standards," said the institution on the project, which has also asked questions about his justice, Since then, it has not been published in any scientific journal.

The Chinese press has for its part recognized today that the study controversies between scholars and the public in the country.

The China Daily Daily announces the & # 39; s disadvantage & # 39; about ethics and its effectiveness, and show that the parents of # 39; The two babies are HIV positive, say Bai Hua, head of Baihualin, an unregulated organization treated with people with HIV. illness,

Meanwhile, more than 120 academies of Chinese academic community in & nbsp; Responses to Sina Weibo, the Chinese equivalent of Twitter, that "any attempt" to make changes in human embryos by genetic modifications is "crazy," and that Roommates these babies contribute "a high risk".

"The government must take rapid measures to support research on the subject," adds Chinese scientists.

The controversy also comes one day for researchers on this field beginning an important meeting on the change of genome, which takes place from 27 to 29 November in Hong Kong.

Generally, the current nature is also a member of a discussion, and argues in an article that the anonymous "outrage" was caused by the international scientific community and that, as it were, "would represent a significant ship in the use of the change of human genome. "

"It is frozen, dangerous and responsible," said Joyce Harper, a researcher at University College London, this publication.

"This experiment provides ordinary and healthy children at risk without requiring real benefits," writes the magazine.

The nature of this kind of instrument has been used to date only to investigate its elimination of disease-changing mutations, and adding that the scientific community "has long asked" the establishment of ethical guidelines for a long time That would be a matter of fact.

In 2016 a group of Chinese scholars pioneers in use in people, especially with liver cancer, genetic modification technology CRISPR, or the report of the magazine Natuer was used.

Scientists in the United Kingdom have discovered that CRISPR gene editing technology has caused more damage to cells than previously believed, according to a study published this year by the same magazine.
