Tijaabada shaybaadhka, jawaab adag oo T-cell ah oo ka dhan ah coronaviruses-ka keena calaamadaha hargabka caadiga ah ayaa lala xiriiriyay difaac weyn oo covid-19 ah.
Dadka leh jawaab celin adag oo ka hortag ah coronaviruses-ka keena calaamadaha hargabka caadiga ah waxaa laga yaabaa in si wanaagsan looga ilaaliyo covid-19, taasoo sare u qaadeysa rajada laga qabo in la gaaro tallaalka pan-coronavirus.
Ricardo da Silva Antunes oo ka tirsan Machadka La Jolla ee Immunology ee California iyo asxaabtiisa ayaa falanqeeyay muunado dhiig ah oo laga soo aruuriyay 32 qof intii u dhaxeysay 2016 iyo 2019, ka hor inta uusan covid-19 soo bixin. Tijaabooyin badan ayaa laga qaaday qof kasta muddo lix bilood ah ilaa saddex sano.
Kooxdu waxay rabeen inay arkaan sida unugyada dif壯陽藥 aaca jirka ee shaybaaradan ay uga jawaabeen afar coronaviruses oo sababa astaamo u eg hargabka iyo sidoo kale nooca SARS-CoV-2 ee asalka ah, kaasoo ka soo baxay Wuhan, Shiinaha, dhamaadka 2019.
Fasalka coronavirus dhexdiisa, toddobo nooc ayaa la og yahay inay ku dhacaan aadanaha. Kuwaas, afar fayras ayaa keena calaamado hargab caadi ah. Waxa kale oo jira SARS-CoV, oo sababa xanuunka daran ee neef-mareenka (SARS); MERS-CoV, oo sababa xanuunka neef-mareenka ee Bariga Dhexe (MERS); iyo SARS-CoV-2, oo ah sababta masiibada socota.
Da Silva Antunes ayaa sheegay in ay muhiim ahayd in la isticmaalo muunado la qaaday ka hor faafitaanka.
“Tani waxay la macno tahay marka aan eegno natiijooyinkayaga, waxaan ognahay inay sabab u tahay xusuusta difaac ee hore u jirtay iyo inaysan ku wasakhaysan jawaabaha difaaca ee dadku ee SARS-CoV-2.”
Daraasadii ugu dambeysay, cilmi-baarayaashu waxay isku dareen dhiigga ka qaybgalayaasha iyo peptides – xadhkaha amino acids – oo ka soo jeeda hargabka kala duwan ee u eg coronaviruses.
Jawaabaha difaaca waxaa caadi ahaan kiciya jirka oo aqoonsanaya peptides-ka fayraska. Marka xigta, waxay qiyaaseen T-cell iyo jawaabaha ka hortagga unugyada dhiigga marka ay la kulmaan fayrasyadan. Iyaga oo eegaya muunado badan oo ka qaybgale kasta, cilmi-baarayaashu waxay ogaadeen in T-cell iyo jawaabaha antibody-ku ay ahaayeen kuwo deggan oo joogto ah dhammaan afarta hargab-sida coronaviruse ee caadiga ah.
Marka la eego unugyada T-yada, kuwaas oo qaarkood ay u badan tahay in lagu hawlgeliyo dib-u-qaadista dhawaanahan, waxay go’aamiyeen jawaabaha difaaca jirka inaysan sabab u ahayn dib-u-celinta caadiga ah.

Taa beddelkeeda, jawaabcelinta difaacu waxay noqon kartaa mid deggan. Da Silva Antunes wuxuu qiyaasayaa in haddii hargabkan caadiga ah ee coronaviruses-ka ah ay soo saaraan jawaab celin difaac oo isku mid ah, ay dhalin karto xasuus difaac deggan Read more: One in 8 people got long covid after infection early in the pandemic
