Krievu biologs Deniss Rebrikovs intervij urnlam Nature paststja, ka ir gatavs modifict cilvka gnu un veikt embriju implantciju. Zintnieks ir nobriedis veikt eksperimentu jau aj gad, ja saems atbilstou atauju. Eksperiment paredzts "atslgt" gnu, kas kod olbaltumvielas, kuras auj HIV iekt organisma ns.
Lai implanttu embrijus, kam rediti gni, biologs plno modifict gnu CCR5, pie kura strdjis ar nieu biologs He Czankujs, kur 2018. gada novembr pazioja par pirmo entiski modificto brnu radanu.
Pc Rebrikova vrdiem, via gna modificanas metode bs mazk riskanta un vairk tiski pamatota.
Eksperimenta veikanas iespjamba zintniekiem izraisjusi vairkus jautjumus. Piemram, virkne specilistu uzskata, ka vl nav izstrdta atbilstoa tehnoloija. Tpat nopietnus iebildumus rada eksperimenta tisk puse.
Deniss Rebrikovs ir Kulakova vrd nosaukt Dzemdniecbas, ginekoloijas un perinatoloijas nacionl medicnas centra gnu redianas laboratorijas vadtjs..
