Echiche Ndị Dị Mkpa nke Ọgwụ Mgbochi MRNA
ọgwụ mgbochi mRNA, ma ọ bụ messenger RNA, bụ ihe ọhụrụ na ọgwụ mgbochi nke na-eji akụkụ ụfọdụ nke koodu mkpụrụ ndụ ihe nketa nke nje iji kpalite mmeghachi omume ahụ ji alụso ọrịa ọgụ. N'adịghị ka ọgwụ mgbochi ọdịnala, nke nwere ike iji ụdị nje ma ọ bụ nje bacteria na-adịghị ike ma ọ bụ nke na-adịghị arụ ọrụ, ọgwụ mgbochi mRNA na-eji ozi mkpụrụ ndụ ihe nketa ozugbo. Mgbe a gbanyere ya n'ime ahụ, ọgwụ mgbochi ndị a na-akụziri mkpụrụ ndụ anyị ka ha mepụta protein ndị na-akpali mmeghachi omume ahụ ji alụso ọrịa ọgụ.
Ụkpụrụ Ndị Dị Mkpa nke mRNA
Iji ghọta otu ọgwụ mgbochi mRNA si arụ ọrụ, anyị kwesịrị ibu ụzọ ghọta ihe mRNA bụ. mRNA na-anọchite anya messenger RNA, molekul nke na-ebu ntuziaka maka mmepụta protein site na DNA ruo na ribosomes, ebe a na-emepụta protein na mkpụrụ ndụ. N'ihe gbasara ọgwụ mgbochi mRNA, mRNA a gbara ọgwụ nwere ntuziaka maka ime otu n'ime protein nje - mana ọ bụghị nje ahụ dum n'onwe ya.
Mmepe Ọgwụ Mgbochi mRNA
Mmepụta ọgwụ mgbochi mRNA gụnyere ọtụtụ nzọụkwụ dị mkpa. Nke mbụ, ndị ọkà mmụta sayensị na-achọpụta otu protein dị mkpa n'ime nje ahụ nke nwere ike ịkpalite nzaghachi mgbochi ọrịa. N'ihe gbasara SARS-CoV-2, nje nke na-akpata COVID-19, protein dị mkpa a bụ protein spike (S), nke nje ahụ na-eji abanye n'ime mkpụrụ ndụ mmadụ. Ozugbo achọpụtara protein ahụ, a na-ekewapụ ozi mkpụrụ ndụ ihe nketa nke na-egosi ya ma detuo ya na mRNA emepụtara.
Otu ọgwụ mgbochi mRNA si arụ ọrụ n'ahụ
1. Ịgba ọgwụ mgbochi:
A na-agba ọgwụ mgbochi mRNA n'ime akwara, ọtụtụ mgbe n'elu ogwe aka. O nwere ihe ndị na-eme ka mmịpụta ahụ dị nro (lipid) kpuchie mmịpụta ahụ, na-echebe ya ka ọ ghara imebi ma na-enyere ya aka ịbanye n'ime sel.
2. Nsụgharị nke mRNA:
Mgbe ọgwụ mgbochi mRNA banyere n'ime mkpụrụ ndụ mmadụ site na endocytosis, a na-ahapụ mRNA n'ime cytoplasm nke mkpụrụ ndụ ahụ. Na cytoplasm, ribosomes—igwe na-emepụta protein n'ime mkpụrụ ndụ ahụ—gụọ usoro mRNA a wee malite imepụta protein e tinyere na koodu. N'ihe gbasara ọgwụ mgbochi COVID-19, protein e mepụtara bụ protein SARS-CoV-2 spike.
3. Ngosipụta Antigen:
A na-agbanwe ma na-egosi protein spike ọhụrụ ahụ n'elu mkpụrụ ndụ mmadụ site na mkpụrụ ndụ MHC (Major Histocompatibility Complex). N'oge a, sistemu ahụ ji alụso ọrịa ọgụ na-amata protein spike dị ka nke mba ọzọ.
4. Mmeghachi omume nke ahụ ji alụso ọrịa ọgụ:
Iji malite mmeghachi omume mgbochi ọrịa, mkpụrụ ndụ ndị na-eweta antigen (APCs), dị ka mkpụrụ ndụ dendritic, na-ejide protein spike ma hazie ya nke ọma. APCs na-eme ka mkpụrụ ndụ T na mkpụrụ ndụ B rụọ ọrụ, ụdị mkpụrụ ndụ ọbara ọcha nke na-arụ ọrụ dị mkpa na mmeghachi omume mgbochi ọrịa na-agbanwe agbanwe. Mkpụrụ ndụ T na-enyere aka ime ka ogbugbu mkpụrụ ndụ ndị butere ọrịa na mmepụta nke protein cytokine nke na-ahazi nzaghachi mgbochi ọrịa. Mkpụrụ ndụ B na-akwaga na plasma ma na-emepụta ọgwụ mgbochi kpọmkwem maka protein spike.
5. Mmepụta nke Ncheta Ahụ́ Ike:
Mgbe usoro nzaghachi a gasịrị, ahụ na-emepụta ebe nchekwa ahụ ji alụso ọrịa ọgụ. Mkpụrụ ndụ ncheta B na mkpụrụ ndụ ncheta T ga-echeta "protein spike". Ọ bụrụ na ahụ ekpughere nje virus mbụ ahụ n'ọdịnihu, sistemu ahụ ji alụso ọrịa ọgụ nwere ike ịmata ozugbo ma wakpo ya na arụmọrụ ka mma, na-egbochi mmepe nke ọrịa ahụ.
