Team & # 39; scientists from the University & # 39; Shenzhen, China, stated that created the first baby b & # 39; genetic engineering with a view to making them "resistant to diseases", reported the publication MIT Technology Review, underlined by the Argentine specialists but approached with & # 39; caution.
He Jiankui, scientist who conducted research which was used gene editing technique known as Crispr, Revealed the process & # 39; fertilization was still ongoing until the newborn twins Lulu and Nana, "genetically modified" b & # 39; such that "Can not get the AIDS virus (HIV)."
He Jiankui, responsible for the fact unprecedented & # 39; genetic manipulation, in his laboratory in southern China – AP
"The results indicated that the operation worked with & # 39; correct way, as planned", Assured in the Asia & # 39; a video on YouTube.
The results of & # 39; this study were originally published yesterday by the specialist journal MIT, Although local media (such as, for example, the newspaper China Daily) said today it still lacks a "constancy".
He, who announced that next month "will be announced more details of the investigation," said the modification did not tfittexx to eliminate genetic diseases but "to babies given natural ability to withstand possible future infection -HIV ".
"The technology & # 39; & # 39 Crispr used in; this case to eliminate the gateway to the AIDS virus (HIV)", explained in dialogue. Télam with Marcelo Rubinstein, researcher at the Research Institute on Genetic Engineering and Molecular Biology (Ingebi) of & # 39; Conicet,
"Until now no one has ever reported that created a genetically modified babies, So they can be the first, "added the specialist, who is also Professor of Genetic Engineering in the Faculty of Exact Sciences UBA.
The Chinese scientists claim to have created genetically modified babies and surprised world – AP
B & # 39; link with the technique (Crispr), Rubinstein stressed "it is possible to be used with & # 39; level & # 39; security potentially very high", adding that "increase the technological arsenal that began to be used 40 years ago the first test tube baby, With aggregate notorious here one gene is modified by & # 39; direct and direct way in new babies ".
"This change in the genetic code is inerettabbli, so children and children of & # 39; these genetically modified babies can be carriers of new mutations," he continued.
While Jiankui He explained that the aim of his research is to prevent disease by & # 39; improvements in DNA, Rubinstein is clear that "subjective appreciation". and not necessarily potential prevention & # 39; disease by modifying the genome should be read as improving itself ".
However, the Argentine specialist emphasized that "it is undoubtedly a very interesting area of & # 39; research".
"Already there were other types of & # 39; presentations in the United States using the same technology in the repair of the mutation, but in & # 39; that case the experiment was interrupted in embryonic and babies did not manage to be born ", detailed.
For his part, Sergio Papier, a specialist in Reproductive Medicine, told Telam that "gene editing is a valuable alternative for the future", Although it found that "at present remains & # 39; experimental method until proven effectiveness and its security protocols & # 39; are rigorous research of science, legal and ethical".
F & # 39; this sense, Rubinstein said that "obviously this topic will issue meetings & # 39; & # 39 panels; ethics will address the issue at & # 39; each country."
"But ethics is a cultural construction changed so it is difficult to predict x & # 39; will happen in & # 39; short and medium term using the & # 39; that the gene editing technology" , said.
