Mbere yo gusesengura “niba dukwiye guhangayikishwa na Omicron cyangwa tutabikora”, reka tubanze tumenyane na SARS-CoV-2 Omicron, yagaragaye gusa muri Afurika y'Epfo ku ya 9 Ugushyingo 2021, yazengurutse isi mu mpera z'ubutaha ukwezi no gukora amagambo nkindwara zanduye, dosiye ya gatatu na boosters mubushakashatsi bushyushye.

Poroteyine ihindagurika cyane itugora cyane kwirinda virusi.

Ishusho ya microscopique ya electron mu ntangiriro yiyi ngingo nifoto yambere ya “Omicron” ku isi yashyizwe ahagaragara na Li Ka Shing ishami ry’ubuvuzi, kaminuza ya Hong Kong (HKUMed) ku ya 8 Ukuboza 2021:

Ubuso bwa virusi ya virusi ifite ishusho imeze nk'ikamba, ari yo proteine ​​spike (S protein) ikoreshwa na virusi mu gutera selile.

Virusi yishingikiriza kuri poroteyine zo mu bwoko bwa spike kugira ngo ihuze na reseptors hejuru y’akagari, bituma uburyo bwa endocytose bw’akagari bwugurura umuryango w’umwanzi uteje akaga hanyuma ugashyira ingirabuzimafatizo kugira ngo ubafashe kwigana uduce duto twa virusi kugira ngo twanduze selile nyinshi.

Kubera iyo mpamvu, poroteyine ya spike ntabwo ari urufunguzo rwa virusi yinjira mu ngirabuzimafatizo gusa ahubwo ni n’intego y’urukingo rwo guhugura sisitemu y’umubiri “kumenya” no kumenya virusi.Uko urwego rwa mutation rwinshi, niko byoroshye ko antibodies zatewe ninkingo zibura.

Uhereye ku ishusho ikurikira ugereranije na moderi eshatu za “Delta” na “Omicron” spike proteine ​​zasohowe n’ibitaro bizwi cyane bya Bambino Gesu i Roma ku ya 27 Ugushyingo 2021, urashobora kumva impamvu Omicron yandura kurusha Delta.

Imyanya irangwa nibara ni uturere twahinduwe dutandukanye na virusi yumwimerere.Dukurikije isesengura, byibuze hari ihinduka ryingenzi 32 ryingenzi muri proteine ​​ya spike ya “Omicron”, irenga kure cyane “Delta”, kandi uturere twahinduwe cyane (umutuku) nabwo twibanda kumyanya ikorana ningirabuzimafatizo zabantu.

Ihinduka nk'iryo ryorohereza “Omicron” gutera ingirabuzimafatizo z'abantu kubyara, gukwirakwira mu bantu no kwirinda ubudahangarwa buterwa n'inkingo, biganisha ku kwandura cyangwa kwandura.

“Omicron” yanduza byoroshye bronchus ariko ntibishoboka ko yinjira mu bihaha.

Dukurikije ibyavuye mu bushakashatsi bwashyizwe ahagaragara na HKUMed ku rubuga rwayo rwa interineti ku ya 15 Ukuboza, variant ya Omicron yigana inshuro zigera kuri 70 kurusha Delta hamwe na Covid-19 y’umwimerere muri bronchus y’abantu ariko ikaba itari nziza mu ngingo z’ibihaha by’abantu.

Ibi birashobora gusobanura impamvu "Omicron" ikwirakwira vuba mugihe ibimenyetso byambere byanduye (umuhogo wuzuye, izuru ryuzuye) birashobora kwibeshya byoroshye kubera ubukonje busanzwe ariko ubukana bwindwara ni buke.

Ariko ntukifate nabi kuko "Omicron" idakunze gutera indwara zikomeye.Ninde uzi icyo ibisubizo byanyuma bidutegereje?

Ikirenzeho, hariho "Delta" na "Grippe" baracyatureba icyarimwe!Inzira nziza yo kubyirinda nukugerageza kugumana ubudahangarwa bwacu murwego rwo hejuru burimunsi.

Ntidukeneye rero guhangayikishwa cyane na “Omicron” ariko tugomba kwitonda kugirango dufate ingamba.

Byaba bimeze bite iyo selile yanduye variant ya Omicron?

Reba kuri microscopique ya electron ikurikira yatanzwe na HKUMed.

Iyi ni micrografi ya electron ya selile ya Vero (impyiko y'inguge) nyuma yamasaha 24 yanduye na Omicron variant ya SARS-CoV-2.Urashobora kubona ko virusi nyinshi zigenda ziyongera mumitsi ya selile, kandi uduce duto twa virusi twagiye twiyongera turekurwa hejuru ya selile biteguye gukora akazi kabo.

Iyi ni virusi nshya yakozwe na virusi ikoresheje “selile imwe”.Birihuta rwose!Kubwamahirwe, ni ubushakashatsi bwa vitro selile.Niba bibaye muri vivo, ntituzi umubare w'ingirabuzimafatizo zizababara, kandi uwanduye muri iki gihe usanga adafite ibimenyetso;iyo umuntu yumva nabi kandi ashaka kubikumira, biratinze!

Nyuma yo kwandura, virusi zimwe zizaba ziri imbere muri selile mugihe zimwe zizaba hanze ya selile.Sisitemu yubudahangarwa izahangana na virusi muburyo butandukanye.

Antibodies ziterwa no gukingirwa zishobora gufata gusa (kutabogama) virusi hanze ya selile.Niba virusi ishobora gufatwa ikimara kwinjira mu kagari, ibintu biroroshye;niba virusi yanduye selile, selile yumubiri ikenera gusohora interferon kugirango ihagarike kwandura virusi mu ngirabuzimafatizo no kugabanya ubwinshi n’umuvuduko w’ikwirakwizwa rya virusi kandi ikenera kandi “selile T selile” cyangwa “selile naturel selile” kugira ngo yice selile zanduye.

Virusi zombi zafashwe na antibodies zica selile zanduye zikenera macrophage kugirango zifate bits.Mbere yibi, macrophage na selile dendritic bigomba kandi gufasha kohereza ibimenyetso kuri "umufasha T selile", abayobozi bakuru ba sisitemu yumubiri, hanyuma bigatanga amabwiriza yukuri yo gukora selile cytotoxic T no kutabuza antibodi.

Inkingo irashobora gutera antibodies, kandi imiti igabanya ubukana irashobora kubuza kwandura virusi mu ngirabuzimafatizo no kugabanya ikwirakwizwa rya virusi.Ariko, kugirango rwose uhanagure virusi, ikenera buri kintu cyose cyumubiri wumubiri gukangurwa no gushimangirwa.

None, nyuma yo gukingirwa, nigute ushobora kongera byimazeyo ingirabuzimafatizo, gushimangira ubudahangarwa bw'umubiri, kunoza imikorere yubudahangarwa, guteza imbere ubudahangarwa bw'umubiri, no kwirinda gucanwa cyane?

Kuva ubushakashatsi mu myaka ya za 90,Ganoderma lucidumbyagaragaye ko byihutisha imikurire ya selile dendritic, kugenga itandukanyirizo rya selile T, gushimangira umusaruro wa antibodies na selile B, guteza imbere itandukaniro rya monocytes-macrophage, no kuzamura ibikorwa byingirabuzimafatizo zica, bifasha mukwiyongera kwinshi ingirabuzimafatizo hamwe no gusohora cytokine zitandukanye, kandi bigira ingaruka zuzuye muburyo bwo kwirinda indwara.Izi ngaruka zose zavunaguye mubishushanyo bikurikira.

Mugukurikirana, tuzagusobanurira byimbitse "kukiGanoderma lucidumirashobora kudufasha gushimangira ubudahangarwa dukeneye kurwanya virusi ”binyuze mu mpapuro nyinshi zasohotse mu binyamakuru mpuzamahanga.Mbere yibyo, turizera ko watangiye kuryaGanoderma lucidumkuko ubudahangarwa bwa buri munsi ni ngombwa cyane.Gusa nukubungabunga sisitemu nziza yumubiri burimunsi dushobora kurinda umutekano wacu burimunsi.
