Lo'da hidde ahaan la beddelay si loo soo saaro caanaha hypoallergenic

Cilmi-baarayaasha Ruushku waxay ku dhawaaqeen guusha cloning lo'da, kaas oo hidde-sidayaasha hidde-sidayaasha la bedelay rajada laga qabo in la soo saaro caanaha ka hortagga xasaasiyadda, sida laga soo xigtay "Daily Mail" ee Ingiriiska.

Lo'da la jeexjeexay ayaa hadda jirta 14 bilood, miisaankeedu waa nus tan, wuxuuna u muuqdaa inuu leeyahay wareeg taran oo caadi ah.

"Tan iyo May, lo'du waxay maalin walba ka shaqaynaysay daaqa iyadoo ka mid ah lo'da kale ee machadka," ayay tiri Galina Singina, oo ah cilmi-baare ka tirsan Xarunta Sayniska Federaalka ee Ernst ee Xannaanada Xoolaha, iyadoo xustay in "ay qaadatay waqti in la qabsado, laakiin si dhakhso ah ayey u dhacday. dhacay.”

laba guulood

Guusha tijaabadu waa laba arrimood, sida lagu sheegay warbixin ka soo baxday Machadka Sayniska iyo Tignoolajiyada ee Skoltech ee Moscow, sababtoo ah cilmi-baarayaashu waxay ku guulaysteen inay xidhaan sac awood u leh inuu la qabsado inta kale ee adhiga ah marka laga reebo isbeddelka hidde-sideyaasha si ay u kala horreeyaan. si aan loo soo saarin borotiinka, kaas oo keena dulqaad la'aanta lactose ee bini'aadamka.

Singina iyo asxaabteeda ka tirsan Machadka Skoltech iyo Jaamacadda Gobolka Moscow waxay isticmaaleen tignoolajiyada CRISPR/Cas9 si ay u "garaacdaan" hidde-sideyaasha ka mas'uulka ah beta-lactoglobulin, borotiinka keena "lactose malabsorption", oo loo yaqaan dulqaad la'aanta lactose.

Dhibaato wax ka beddelka hidde-sidayaasha lo'da

Cilmi-baadhayaashu waxay awoodeen inay xidhaan lo'da iyagoo isticmaalaya SCNT, iyada oo xudunta unugga ku-deeqaha caadiga ah loo wareejiyo ukun iyada oo xudunta laga saaray. Uurjiifka ka dhashay ka dib waxaa lagu tallaalay ilmo galeenka sac ilaa heerka dhalmada.

Inkasta oo jiirarka hidde ahaan la beddelay ay yihiin dhacdo caadi ah oo caadi ah, wax ka beddelka hidda-wadaha noocyada kale ayaa si weyn u dhib badan, sababtoo ah kharashka badan iyo dhibaatooyinka, ayuu yiri Peter Sergeev, oo ah borofisar ka tirsan Machadka Skoltech iyo qoraaga daraasadda, natiijooyinka kuwaas oo lagu daabacay Doklady Biochemistry iyo Biophysics. taranka iyo taranka.

mashruuc weyn

"Marka, habka u horseedaya taranka xoolaha ee caanaha hypoallergenic waa mashruuc cajiib ah," ayuu raaciyay Sergeev.

Qiyaastii 70 boqolkiiba dadka adduunka ayaa la ildaran nooc ka mid ah lactose malabsorption, sida laga soo xigtay Machadka Qaranka ee Sonkorowga iyo Cudurrada dheef-shiidka iyo kelyaha, taas oo ku adkeynaysa inay dheefshiido caanaha iyo waxyaabaha kale ee caanaha laga keeno.

Borofisar Sergeev waxa uu sharaxay in samaynta sac run ahaantii ay tahay tijaabo, halka tallaabada xigtana ay noqon doonto in la tallaalo daraasiin sac ah oo wata hiddo-wadaha la beddelay, si loo horumariyo taran lo’ ah oo soo saara caano dabiici ah oo hypoallergenic ah.
