Chigadzirwa chesainzi chekurapa chirwere chemoyo

Mukutsvaga kutsva kutsva, masayendisiti achanyorazve DNA nechinangwa chekutsvaga kurapa kwekutanga kwepasi rose kwezvirwere zvemoyo, mune izvo zvinogona kutsanangurwa se "nguva yakasimba" mumunda wemishonga yemoyo.

Maererano nezvakadhindwa ne "Boldsky" webhusaiti, masayendisiti anotungamira pasi rose kubva kuUnited Kingdom, United States neSingapore vakabatana pachirongwa che "Cure Heart" kugadzira vaccine yevarwere vemoyo. Sekureva kwenhau, British Heart Foundation yakapa € 30 miriyoni kuchirongwa ichi chinoponesa hupenyu.

Kekutanga, vatsvakurudzi vachashandisa maitiro chaiwo emajini, anozivikanwa sekushandurwa kwekutanga, mumoyo kugadzira uye kuedza kurapwa kwekutanga kwezvirwere zvetsandanyama yemoyo, nechinangwa chekukanganisa majini asina kunaka.

Chirwere chemoyo chekugara nhaka

"Chirwere chemoyo chekugara nhaka" ishoko rinosanganisira zvirwere zvose zvemwoyo zvinopfuudzwa kubva kuvabereki kuenda kuvana vavo, kureva kuti kana mumwe kana vabereki vose vane gene rakaremara kana rakashandurwa, pane mukana we50 / 50 wekupfuudza kuvana. Zvimwe zvirwere zvemoyo zvinogarwa nhaka zvinosanganisira hypertrophic cardiomyopathy uye hypercholesterolemia.

Vamwe vanhu vane hosha yemwoyo inogarwa nhaka vangasava nezviratidzo zvakawanda, uye chirwere chacho hachiongororwi kutozosvikira pashure pokunge varohwa nehana kamwe kamwe, kupera simba, kana kuti kufa kamwe kamwe. Nhamba dzinoratidza kuti 0.8 kusvika 1.2% yevacheche pasi rose vanobatwa nechirwere chemoyo.

Nhoroondo mukana uye 30 makore ekutsvakurudza

Komiti yekuraira inotungamirwa naProfessor Sir Patrick Vallance, chipangamazano mukuru wesainzi kuhurumende yeBritain, vakasarudza boka rine chekuita nekudzidza kwakakosha, ukuwo Muzvinafundo Hugh Watkins, wekuYunivhesiti yeOxford uye muongorori mukuru weCure Heart project, akataura kuti cardiomyopathy. Chirwere chakakomba.Chimiro “chakajairika” munyika yose uye chinozivikanwa kuti chinokanganisa munhu mumwe chete pavanhu 250.

Muzvinafundo Watkins akawedzera, achitsanangura chidzidzo ichi se "mukana wenguva-mune-chizvarwa" wakanangana nekuderedza kushushikana kunoramba kuripo pamusoro pekufa kamwe kamwe, kutadza kwemoyo uye zvingangodiwa zvekuisirwa moyo.

Muzvinafundo Watkins akatsanangura, "Mushure memakore makumi matatu ekutsvagisa, akawanda majini uye hurema hwemajini zvakawanikwa zvinokonzeresa kwakasiyana cardiomyopathy uye mashandiro avanoita. Zvinotendwa kuti pachave nekurapa kwejeni kunowanikwa kutanga miedzo yekiriniki mukati memakore mashanu anotevera. "

Kugadziriswa kwemajini akaremara

Zvinotarisirwa kuti purogiramu itsva yekutsvakurudza ichagadzirisa zvachose kuchinja kwemajini kunokonzera kukonzera matambudziko emwoyo.

Muchirevo chechinyorwa chino, Christine Seidman, purofesa paHarvard Medical School uye muongorori aitungamirira basa racho, akatsanangura kuti chinangwa chaiva “chokugadzirisa mwoyo” uye kudzorera kushanda kwayo kwemazuva ose, achitsanangura kuti “machinjiro akawanda akaonekwa pakati pevarwere anotungamira. pakuchinjazve bhii rimwe kubva paDNA code, zvinoreva kuti pane mushonga nekuchinja monogram uye kudzorera bumbiro racho.”

Maererano nevatsvakurudzi, mapiyona anobva kumakondinendi matatu uye akasiyana mumunda wezvinyorwa uye zvakanyatsoruramisa gene editing inobatanidzwa muchidzidzo, miedzo yevanhu haisati yaitwa, asi kuedza kwemhuka kwakabudirira uye kuvimbisa.

Vatsvakurudzi vakawedzera kuti pane tarisiro yekuti vanhu vari panjodzi yekubatwa nechirwere chemoyo nekuda kwekuvapo kwemajini asina kunaka mumhuri dzavo vanokwanisa kuwana kurapwa chirwere chavo chisati chatanga.
