B hlwb feem ntau ua haujlwm los ua cov tshuaj tiv thaiv kab mob tiv thaiv antigens, ua raws li cov tshuaj tiv thaiv kab mob tam sim no (APCs), thiab nws thiaj li loj hlob mus rau hauv lub hlwb B kom muaj kev tiv thaiv mus ntev. B hlwb tau txais clonal xaiv thiab txhim kho zoo ib yam li T hlwb nrog qee qhov sib txawv.

Lub hlwb twg los ntawm kev xaiv clonal?

Clonal xaiv ntawm lymphocytes: 1) Ib qho hematopoietic qia cell tau txais kev sib txawv thiab kev hloov caj ces los tsim 2) cov lymphocytes tsis paub qab hau nrog ntau yam sib txawv antigen receptors. Cov uas khi rau 3) antigens los ntawm lub cev cov ntaub so ntswg raug puas tsuaj, thaum tus so loj hlob mus rau hauv 4) inactive lymphocytes.

Pob B hlwb puas raug tshem tawm clonal?

B hlwb ua kom pom kev sib raug zoo rau tus kheej lub hlwb tuaj yeem nkag mus clonal deletion hauv pob txha pob txha. Qhov no tshwm sim tom qab kev ua haujlwm B-cell receptor (BCR) tau sib sau ua ke.

Vim li cas nws tseem ceeb uas B hlwb raug xaiv clonal?

B hlwb muaj nyob raws li clones muab los ntawm ib lub xovtooj. Yog li cov tshuaj tiv thaiv kab mob thiab lawv cov kab mob sib txawv tuaj yeem lees paub thiab / lossis khi tib lub ntsej muag tshwj xeeb uas muaj cov tshuaj lom neeg macromolecules ntawm ib qho antigen. Clonality muaj qhov tshwm sim tseem ceeb rau lub cim xeeb immunogenic

B hlwb raug xaiv qhov twg?

Ob leeg B thiab T hlwb tau xaiv qhov zoo thiab tsis zoo hauv thawj lub cev lymphoid. Kev xaiv zoo yuav tsum muaj kev taw qhia los ntawm antigen receptor rau lub cell kom ciaj sia. Txhim kho B hlwb raug xaiv zoo thaum lub pre-B receptor khi nws ligand.
