Memory B hlwb raug tsim tawm thaum cov lus teb thawj zaug rau cov tshuaj tiv thaiv T-dependent. Lawv tsis tsim cov tshuaj tiv thaiv, piv txwv li, tsis tiv thaiv, tshwj tsis yog tias rov raug cov tshuaj tiv thaiv kab mob ua rau lawv qhov sib txawv rau hauv cov tshuaj tiv thaiv uas tsim cov plasma hlwb.
Lub cim xeeb B hlwb tsim cov tshuaj tiv thaiv li cas?
Txhua B cell tsim ib hom tshuaj tiv thaiv kab mob, txhua tus muaj qhov tshwj xeeb antigen-binding site. Thaum lub cev tsis muaj zog lossis nco B cell yog qhib los ntawm antigen(nrog kev pab ntawm tus pab T cell), nws proliferates thiab sib txawv rau hauv cov tshuaj tiv thaiv-secreting effector cell.
Cov hlwb twg tuaj yeem tsim cov tshuaj tiv thaiv?
A lymphocyte yog ib hom qe ntshav dawb uas yog ib feem ntawm lub cev tiv thaiv kab mob. Muaj ob hom lymphocytes tseem ceeb: B hlwb thiab T hlwb. Cov B hlwb tsim cov tshuaj tiv thaiv uas siv los tua cov kab mob invading, kab mob, thiab co toxins.
Lub hlwb puas muaj kev tiv thaiv?
Differentiation of memory B cells rau hauv plasma cells yog ceev tshaj qhov sib txawv los ntawm naïve B hlwb, uas tso cai rau lub cim xeeb B hlwb los tsim ntau dua efficient Secondary immune response Kev ua tau zoo thiab sib sau ua ke ntawm lub cim xeeb B cell teb yog lub hauv paus rau cov tshuaj tiv thaiv thiab tshuaj tua kab mob.
Covid puas ua rau lub hlwb nco?
Lub cev tiv thaiv kab mob tseem ceeb tau tsim tom qab COVID-19, suav nrog tag nrho plaub hom kev tiv thaiv kab mob loj. Kwv yees li 95% ntawm cov neeg mob khaws cia lub cim xeeb tiv thaiv kab mob ntawm ~ 6 lub hlis tom qab kis kab mob. Circulating antibody titers tsis tau kwv yees ntawm T cell nco.

Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Cov tshuaj tiv thaiv puas tiv thaiv kab mob?
Cov ntaub ntawv tshiab kawg qhia tau tias kev txhaj tshuaj tsis yog tiv thaiv tib neeg cov tshuaj tiv thaiv xwb, nws txo qis txoj hauv kev uas lawv tuaj yeem kis tus kabmob mus rau lwm tus. Cov tshuaj tiv thaiv COVID-19 puas tiv thaiv kev sib kis?
Puas yog cov tshuaj tiv thaiv kab mob sib txuas tau suav tias yog kev tiv thaiv kab mob?
Antibody drug conjugates (ADCs) yog ib hom tshuaj tiv thaiv kab mob. Lawv yog tsim los ntawm peb yam: monoclonal antibody (mAb) thiab cytotoxic payload ua los ntawm cov kws khomob kws khomob, uas txuas nrog ua ke siv cov tshuaj sib txuas . Puas yog tshuaj tiv thaiv kab mob tib yam li kev tiv thaiv kab mob?
Cov tshuaj tiv thaiv puas muaj txiaj ntsig tiv thaiv delta variant?
Cov tshuaj tiv thaiv Delta muaj txiaj ntsig zoo li cas ntawm cov tshuaj tiv thaiv COVID-19? Hais txog Delta Variant: Cov tshuaj tiv thaiv muaj txiaj ntsig zoo rau kev mob hnyav, tab sis Delta variant ua rau ntau dua Kev kis kab mob thiab kis tau sai dua li cov qauv ua ntej ntawm tus kab mob uas ua rau COVID-19.
Cov neeg mob tiv thaiv kab mob yuav tsum tau txais cov tshuaj tiv thaiv?
Vim li cas CDC thiaj pom zoo tias cov neeg uas muaj kev tiv thaiv kab mob tiv thaiv kab mob tau txais koob tshuaj mRNA COVID-19 ntxiv los ntxiv rau 2-dose thawj koob tshuaj tiv thaiv kab mob mRNA COVID-19? Cov neeg uas muaj kev tiv thaiv kab mob los yog cov neeg siv tshuaj tiv thaiv kab mob yog nyob ntawm muaj kev pheej hmoo ntau rau tus kab mob COVID-19 hnyav .
