<prompt> Pfupisa nyaya yacho: Masayendisiti anotaura kuti ava pedyo nokugadzira mushonga unogona kurapa HIV. Chikwata chevaongorori chave chichigadzira nzira yokuzvidzivirira nayo inoshandiswa nemabhakitiriya uye kudzidzisa gadziriro iyi yakaita sechisero kuti izive utachiona hweHIV. Mukuedza kwavo, vakawana kuti unyanzvi hwacho hwaigona kubvisa zvakakwana masero anosvika 72 muzana akanga atapukirwa neHIV. Chikwata chevaongorori chave kugadzira nzira yekudzivirira inoshandiswa nemabhakitiriya uye kudzidzisa michina iyi yakaita sechisero kuti izive hutachiona hweHIV inoratidzwa pamufananidzo CRISPR tekinoroji inonyatsochinja zvikamu zvinotarisirwa zvejeniki kodhi. Kusiyana nemamwe mashandiro anoita kuti majini adzikire, Crispr inonanga zvinhu zvinobva mugenomu uye inodzima majini zvachose paDNA. DNA yakatemwa inozivikanwa seyakaputsika kaviri inonyatsotevedzera rudzi rwokuchinja kunoitika nenzira yomuzvarirwo, somuenzaniso pashure pokugara kwenguva refu uri muzuva. Asi kusiyana nemwaranzi yeUV inogona kukonzera kuchinja kwemagene, Crispr inokonzera kuchinja kunenge kuchiitika panzvimbo chaiyo mugenome. Apo gadziriro dzamasero dzinogadzirisa kuputsika kweDNA, dzinobvisa chidimbu chiduku cheDNA. Nenzira iyi, vanzveri vanogona kudzima nemazvo majini chaiwo ari mugenome. Kushanduka-shanduka kwakaita kuti pave nezvimwe zvinhu zvinoshamisa zvikuru zvinodzivirira zvinhu zvipenyu pazvirwere zvinokonzerwa nemasero azvo, anodaro Juan Carlos Izpisua Belmonte, purofesa weSalks Gene Expression Laboratory muCalifornia. Kunzwisisa mashandiro anoita masoja okudzivirira zvirwere ayo mabhakitiriya anozvidzivirira nawo pazvirwere zvinokonzerwa nemavhairasi kwakatigonesa kugadzira nzira itsva dzokurwisa utachiona hunoparadza, hwakadai seHIV, muvarwere. Apo kopi yeutachiona hweHIV inopinda musero romunhu, inogona kuparadza zvikuru. Inodzora mashandiro anoita sero racho pacharo kuti riite makopi ezvinhu zvomuviri zveutachiona uye rinobva raviga makopi aya mumagene esero racho pacharo. Kubva ipapo, sero romurwere rinova fekitari yeHIV, richigadzira makopi matsva eutachiona kuti apararire mumuviri wose. Mishonga iripo yeHIV inonangidzira ngwariro pamatanho akasiana-siana oupenyu uhwu; mimwe inomisa utachiona kuti hurege kubatanidzwa mu...  <response>: Masayendisiti akadzidzisa mabhakitiriya akaita sechisero kuti azive utachiona hweHIV. Vakawana mutoo unobudirira wokugura majini eHIV, uchibvisa utachiona. Izvi zvakaita kuti utachiona hwacho hubviswe mumasero anosvika 72 muzana. Nzira yeCRISPR yakatobvisawo utachiona hweHIV hwakanga husina kushanda muDNA yemasero acho. Ongororo ichangobva kuitwa inoratidza kuti nzira iyi inoshanda pakurwisa utachiona hweHIV huri kushanda, hwakareba, pane kuti hurwise utachiona hwakapfupikiswa, husingashandi.
