Qhov sib txawv tseem ceeb ntawm B hlwb thiab ntshav ntshav yog tias B hlwb yog hom qe ntshav dawb uas ua haujlwm hauv kev tiv thaiv kab mob thaum lub plasma hlwb yog hom B hlwb.
Peb lub cev tiv thaiv kab mob kuaj pom ntau yam kab mob sib kis thiab tiv thaiv peb ntawm ntau yam kab mob. Lub cev tiv thaiv kab mob muaj ob qhov tseem ceeb xws li lub cev tiv thaiv kab mob hauv lub cev (thawj kab ntawm kev tiv thaiv) thiab lub cev tiv thaiv kab mob (kev tiv thaiv theem nrab nrog kev nco). B hlwb thiab ntshav plasma yog ob pawg ntawm cov qe ntshav dawb hauv lub cev tiv thaiv kab mob. B hlwb tsim cov tshuaj tiv thaiv uas ua haujlwm ua cov tshuaj tiv thaiv kab mob thiab tso cov tshuaj tiv thaiv kab mob. Ntawm qhov tod tes, cov plasma hlwb tau qhib B hlwb uas tsim cov tshuaj tiv thaiv ntau.
B Cells yog dab tsi?
B hlwb yog ib hom qe ntshav dawb uas tsim cov tshuaj tiv thaiv kab mob sib txawv rau cov kab mob sib txawv. Yog li, B hlwb yog ib feem tseem ceeb ntawm kev tiv thaiv kab mob. Raws li txoj cai, B hlwb muaj ntau hom xws li naive B hlwb, plasma blast B hlwb, plasma hlwb, thiab nco B cell. Li no, lawv cov dej num sib txawv raws li.
Daim duab 01: B Cell
Naive B hlwb yog thawj hom B hlwb uas tsis raug rau ib qho antigen. Thaum lawv ntsib ib qho antigen, lawv tuaj yeem sib txawv ntxiv rau lwm hom B hlwb. Plasma blast cells yog thawj theem antigen raug B hlwb. Yog li ntawd, lawv tsim ib qho me me ntawm cov tshuaj tiv thaiv. Plasma cells, ntawm qhov tod tes, yog theem kawg ntawm B cell proliferation. Yog li, cov hlwb no tsim cov tshuaj tiv thaiv ntau tshaj plaws. Lub cim xeeb B cell yog qhov dormant theem ntawm B cell proliferation. Yog li ntawd, cov hlwb no muaj lub neej ntev tshaj plaws ntawm tag nrho B hlwb. Nco B hlwb ncig thoob plaws lub cev. Yog li, lawv tsim cov tshuaj tiv thaiv kab mob thib ob - cov lus teb muaj zog dua ntawm kev tiv thaiv kab mob.
Plasma Cells yog dab tsi?
Plasma hlwb yog tag nrho proliferated (activated) B hlwb. Cov hlwb no tsim cov tshuaj tiv thaiv kab mob ntau dua rau cov kab mob tshwj xeeb. B hlwb sib txawv rau hauv cov ntshav plasma vim yog kev ua haujlwm ntawm B cell thaum raug rau cov antigens tshwj xeeb. Cov txheej txheem ntawm plasma cell ntau lawm yog theem kawg ntawm B cell proliferation.
Daim duab 02: Plasma Cells
Plasma cells tuaj yeem tsim cov tshuaj tiv thaiv ntau dua thiab tso rau hauv cov ntshav thiab qog ntshav thaum muaj kab mob. Tom qab ntawd cov tshuaj tiv thaiv uas tsim tau khi nrog lub hom phiaj antigens. Thaum khi, cov tshuaj tiv thaiv no pib qhov nruab nrab lossis kev puas tsuaj ntawm txawv teb chaws cov kab mob antigens. Kev tsim cov tshuaj tiv thaiv kab mob los ntawm cov ntshav plasma tshwm sim kom txog thaum cov antigen raug rhuav tshem thiab tshem tawm ntawm peb lub cev.
Dab tsi zoo sib xws ntawm B cells thiab Plasma Cells?
- B hlwb thiab ntshav ntshav yog ob hom qe ntshav dawb.
- Lawv yog cov lymphocytes uas tsis muaj granules hauv cytoplasm.
- Lawv ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev tiv thaiv; hauv kev tsim cov tshuaj tiv thaiv.
- Ob hom hlwb muaj ib puag ncig zoo li tus nucleus.
Qhov txawv ntawm qhov sib txawv ntawm B cells thiab Plasma Cells yog dab tsi?
B hlwb yog hom qe ntshav dawb. Thaum lawv raug cov antigens, lawv tau qhib thiab hloov mus rau ob peb lwm hom cell. Plasma cell yog ib hom kab mob B uas ua kom muaj zog. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm B hlwb thiab ntshav ntshav.
Ntxiv mus, ob hom cell muaj peev xwm tsim cov tshuaj tiv thaiv. Txawm li cas los xij, plasma cells yog hom cell uas tsim cov tshuaj tiv thaiv ntau tshaj plaws hauv peb lub cev. Yog li, qhov no kuj yog qhov sib txawv ntawm B hlwb thiab cov ntshav ntshav. Tsis tas li ntawd, lwm qhov sib txawv ntawm B hlwb thiab ntshav plasma yog lawv qhov sib txawv. B hlwb tuaj yeem sib txawv rau lwm hom cell thaum cov plasma tsis tuaj yeem.
Cov duab hauv qab no nthuav tawm cov ntaub ntawv ntau ntxiv ntawm qhov sib txawv ntawm B hlwb thiab ntshav ntshav.
Summary – B Cells vs Plasma Cells
Ob leeg B cell thiab plasma hlwb yog lymphocytes thiab ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kab mob. Lawv muaj peev xwm tsim cov tshuaj tiv thaiv. Qhov sib txawv tseem ceeb ntawm B hlwb thiab ntshav plasma yog tias B hlwb yog hom qe ntshav dawb uas tsim cov tshuaj tiv thaiv kab mob sib txawv hauv kev tiv thaiv kab mob thaum lub plasma hlwb yog hom B hlwb. Naïve B hlwb yog thawj hom B hlwb uas tsis raug rau cov antigens. Thaum cov hlwb raug rau cov antigens, lawv qhib thiab hloov mus rau hauv cov ntshav plasma thiab nco B hlwb. Nco B hlwb ncig thoob plaws lub cev thiab tsim cov tshuaj tiv thaiv kab mob thib ob. Plasma cells yog cov hlwb uas tsim cov tshuaj tiv thaiv kab mob siab tshaj plaws ntawm txhua hom B cell. Yog li, qhov no qhia txog qhov sib txawv ntawm B hlwb thiab ntshav ntshav.
