Vim li cas cov menyuam yaus maj mam nrog COVID-19? Cov kws tshawb fawb tau pom ib qho tseem ceeb

Vim li cas cov menyuam yaus zoo li ua tau zoo nrog COVID-19 ntau dua li cov laus? Cov lus nug no cov kws kho mob thiab cov kws tshawb fawb tau nug lawv tus kheej yuav luag txij thaum pib ntawm tus kabmob coronavirus. Cov kws tshawb fawb ntawm Stanford University hauv Asmeskas tau tshaj tawm tias lawv tau pom cov lus teb ua tau. Lawv qhov kev tshawb pom tau luam tawm los ntawm cov ntawv xov xwm muaj koob npe tshawb fawb "Science".

1. Cov menyuam yaus ntawm txhua lub hnub nyoog tuaj yeem kis tau tus kab mob COVID-19, tab sis feem ntau muaj mob me lossis tsis muaj tsos mob
2. Txoj Kev Kawm: Cov ntshav sau los ntawm cov menyuam yaus ua ntej muaj kev sib kis muaj ntau B hlwb uas tuaj yeem khi rau SARS-CoV-2 ntau dua li cov neeg laus cov ntshav. Qhov no txawm hais tias cov menyuam yaus tseem tsis tau raug tus kabmob coronavirus
3. Cov kws tshawb fawb pom zoo tias qhov ua ntej raug rau tib neeg tus mob coronavirus (uas ua rau mob khaub thuas) tuaj yeem ua rau muaj kev tiv thaiv kab mob sib kis, thiab tias cov tshuaj tiv thaiv clonal no tuaj yeem muaj ntau zaus hauv menyuam yaus.

COVID-19 hauv menyuam yaus. Feem ntau kis tus mob coronavirus me me

Twb yog thaum pib ntawm tus kabmob SARS-CoV-2, nws tau pom tias cov menyuam yaus muaj tus kabmob me me nrog tus kabmob coronavirus - cov tsos mob ntawm COVID-19 feem ntau tsis tuaj lossis cov tsos mob me.

Nws yog ib qho tsim nyog xa mus rau ntawm no rau cov ntaub ntawv hais txog qhov mob hnyav dua ntawm COVID-19 ntawm cov menyuam yaus. - Nws muaj tseeb tias ntau tus neeg hauv pab pawg menyuam yaus thiab cov tub ntxhais hluas muaj qee cov tsos mob tom qab kis tus kabmob SARS-CoV-2. Txawm li cas los xij, nws tsis muaj tseeb thiab kuv tsis nco qab nws hauv kuv lub tsev kho mob tias cov kev kawm COVID-19 hnyav hauv pab pawg hnub nyoog no tau loj hlob sai - Prof. Magdalena Marczyńska, tus kws tshaj lij ntawm kev kis kab mob hauv cov menyuam yaus. Tus kws kho mob tau hais tias feem ntau cov menyuam yaus tseem kis tus kabmob SARS-CoV-2 tus kabmob me me.

Lub tsev kho mob Mayo muaj koob npe kuj tseem hais txog qhov no hauv nws txoj kev sib txuas lus (Lub koom haum ua haujlwm tshawb fawb thiab kev kho mob, nrog rau kev saib xyuas neeg mob sib xyaw). Raws li nws tau tshaj tawm hauv mayoclinic.org, cov menyuam yaus ntawm txhua lub hnub nyoog tuaj yeem tsim COVID-19, tab sis feem ntau muaj mob me lossis tsis muaj tsos mob.

1. Cov menyuam yaus kis tau tus kab mob COVID-19 li cas thiab lawv cov tsos mob li cas?

Vim li cas qhov no tshwm sim? Cov kws tshawb fawb tau sim daws qhov tsis paub yuav luag txij thaum pib muaj kev sib kis. Qhov kev piav qhia yuav raug pom los ntawm cov kws tshawb fawb los ntawm American Stanford University. Lawv tau tshaj tawm rau lub Plaub Hlis 12 hauv Kev Tshawb Fawb, ib qho ntawm cov ntawv xov xwm muaj koob npe tshaj plaws. Cov kws sau ntawv tau taw qhia tias cov kev tshawb fawb no tseem nyob rau theem pib, tab sis tuaj yeem piav qhia vim li cas cov menyuam yaus muaj kev hloov pauv me ntsis ntawm COVID-19.

Vim li cas cov menyuam yaus zoo dua nrog COVID-19?

Hauv lawv txoj kev tshawb nrhiav cov lus teb rau cov lus nug saum toj no, cov kws tshawb fawb tau tsom mus rau lub cev tiv thaiv kab mob. Thiab, qhov tseeb, lawv pom ib qho tseem ceeb uas tuaj yeem ua lub luag haujlwm (tsawg kawg hauv ib feem) rau kev sib zog ntawm COVID-19 hauv cov menyuam yaus. Tab sis txij thaum pib.

Lub cev tiv thaiv kab mob muaj xws li: cov hlwb xws li B lymphocytes (paub txog "tus yeeb ncuab", tsim cov tshuaj tiv thaiv kab mob), T lymphocytes ( txheeb xyuas thiab rhuav tshem cov kab mob hauv cov hlwb) thiab macrophages (tua cov kab mob thiab lwm cov hlwb txawv teb chaws). Txawm li cas los xij, cov kws tshawb fawb tau sau tseg tias qhov no tsis txhais tau tias peb txhua tus muaj tib lub cev tiv thaiv kab mob. «B lymphocytes yog lub luag haujlwm rau nco txog cov kab mob uas peb lub cev tau ntsib ua ntej, yog li lawv tuaj yeem ceeb toom koj yog tias lawv tuaj hla lawv dua. Nyob ntawm seb cov kab mob dab tsi peb twb tau kis mus rau thiab yuav ua li cas cov receptors uas khaws qhov no >> nco << hloov thiab hloov pauv, peb txhua tus muaj qhov sib txawv >> ntau yam << ntawm lub cev tiv thaiv kab mob " - cov kws tshawb fawb piav qhia.

1. Lymphocytes - lub luag haujlwm hauv lub cev thiab sib txawv ntawm cov qauv [Qhia]

Nco qab tias kev ua haujlwm receptor yog ua los ntawm cov tshuaj tiv thaiv kab mob (immunoglobulins) tam sim no nyob rau saum npoo ntawm B lymphocyte. Lawv tuaj yeem khi rau cov tshuaj tiv thaiv kab mob / kab mob (txhua cov tshuaj tiv thaiv kab mob lees paub ib qho tshwj xeeb antigen), ua rau muaj kev tiv thaiv kab mob tiv thaiv nws (cov tshuaj tiv thaiv kab mob).

Nrog rau tag nrho cov no hauv siab, cov kws tshawb fawb ntawm Stanford University tau tshuaj xyuas seb cov kab mob tiv thaiv kab mob sib txawv li cas ntawm ib tus neeg mus rau lwm tus, tab sis kuj yuav hloov pauv li cas hauv tib neeg lub neej. Lawv pom tias cov ntshav sau los ntawm cov menyuam yaus ua ntej muaj kev sib kis muaj ntau B hlwb uas tuaj yeem khi rau SARS-CoV-2 ntau dua li cov ntshav ntawm cov neeg laus. Qhov no tshwm sim txawm hais tias cov me nyuam tseem tsis tau raug tus kab mob no. Nws ua tau li cas?

COVID-19 hauv menyuam yaus. Lawv lub cev tiv thaiv kab mob ua haujlwm li cas?

Cov kws tshawb fawb piav qhia tias cov receptors tau hais los saum toj no yog tsim los ntawm tib lub ' qaum' hu ua immunoglobulin sequences. Txawm li cas los xij, lawv tuaj yeem hloov pauv lossis hloov pauv, tsim kom muaj ntau yam ntawm cov receptors uas muaj peev xwm rhuav tshem cov kab mob uas lub cev tseem tsis tau cuam tshuam nrog. Peb kov ntawm no lub tswv yim ntawm lub thiaj li hu ua cross resistance. Ua tsaug rau lub cim xeeb ntawm lymphocytes, lub cev tiv thaiv kab mob sai dua thiab muaj zog dua thaum rov sib cuag nrog cov antigen. Yog hais tias qhov no tshwm sim nyob rau hauv cov ntaub ntawv ntawm tus kab mob nrog ib tug zoo xws li cov kab mob, nws yog precisely cross-resistance.

Qhov tseeb, thaum cov kws tshawb fawb tau saib B-cell receptors hauv cov menyuam yaus, lawv pom tias, piv rau cov neeg laus, lawv muaj ntau dua 'clones' tsom rau cov kab mob thiab cov kab mob uas lawv twb tau ntsib lawm. Ntau B hlwb kuj tau pom nyob rau hauv cov menyuam yaus, thiab lawv tuaj yeem 'hloov' kom ua tau zoo tiv thaiv SARS-CoV-2 yam tsis muaj kev sib cuag nrog nws thawj zaug.

Raws li cov kws tshawb fawb, qhov no tuaj yeem yog vim qhov tseeb tias lub cev tiv thaiv kab mob ntawm cov menyuam yaus tau zoo dua mus rau ntau hom antigens tom qab kis tus kabmob sib txawv, tsis tshua muaj kev phom sij tshaj li tus neeg saib xyuas tus kabmob kis tam sim no (nco ntsoov tias tus kabmob coronaviruses yog lub luag haujlwm. rau li 10-20 feem pua ​​​​ntawm cov mob khaub thuas). 'Peb kwv yees tias kev kis tus kab mob coronavirus ua ntej tib neeg tuaj yeem ua rau muaj kev tiv thaiv kab mob sib kis thiab tias cov lus teb clonal no feem ntau tshwm sim thaum menyuam yaus,' cov kws tshawb fawb tau xaus lus hais tias 'kev tiv thaiv kab mob hauv cov menyuam yaus yog qhov tseem ceeb tshwj xeeb vim lawv tsim thawj lub cim xeeb. B lymphocytes, uas ua rau lub cev tiv thaiv yav tom ntej cov lus teb ».

Thaum kawg, cov kws tshawb fawb ntawm Stanford University tau taw qhia tias yuav muaj ntau yam uas ua rau cov menyuam yaus feem ntau muaj cov tsos mob me me ntawm COVID-19. Lawv qhov kev tshawb pom, txawm li cas los xij, tau nthuav tawm qee qhov kev paub tsis meej, muab kev pom rau menyuam yaus B-cell yooj thiab nws lub luag haujlwm hauv kev tiv thaiv kab mob yav tom ntej.

Tej zaum koj yuav txaus siab rau:

1. Ntau tus menyuam yaus muaj lub sijhawm nyuaj ntawm COVID-19. Ib qho kev mob tshwm sim tshwj xeeb tshaj yog tsim nyog
2. COVID-19 tuaj yeem ua rau muaj teeb meem thyroid
3. Cov poj niam cev xeeb tub muaj ntau thiab ntau dua. Yuav ua li cas thaum tus poj niam cev xeeb tub mob nrog COVID-19?
