Qhov sib txawv tseem ceeb ntawm cov ntshav plasma thiab lub hlwb nco yog tias cov ntshav plasma yog theem kawg ntawm B cell proliferation uas tsim cov tshuaj tiv thaiv thaum nco B hlwb yog cov dormant theem ntawm B cell proliferation uas nco ntsoov antigens thiab tshwm sim tam sim ntawd thaum raug. uas antigen lwm zaus.
Muaj ntau hom qe ntshav dawb. Lymphocytes yog ib hom qe ntshav dawb. Muaj ob hom lymphocytes tseem ceeb: B lymphocytes thiab T lymphocytes. Ntuj tua cov hlwb kuj yog hom lymphocytes. B lymphocytes pib thiab loj hlob hauv cov pob txha pob txha. Thaum kuaj pom antigen, B lymphocytes nce ntau thiab pib sib txawv. Qee B lymphocytes tseem nyob ua lub cim xeeb B hlwb thaum muaj ntau B lymphocytes sib txawv rau hauv cov tshuaj tiv thaiv kab mob ua cov ntshav plasma. Lub ntsiab lus tseem ceeb ntawm tsab xov xwm no yog los tham txog qhov sib txawv ntawm lub cim xeeb ntawm cov hlwb thiab cov ntshav ntshav.
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 raws li qhov tshwm sim ntawm B cell activation thaum raug rau ib qho antigen. Cov txheej txheem ntawm plasma cell ntau lawm yog theem kawg ntawm B cell proliferation.
Daim duab 01: Plasma Cells
Plasma cells tuaj yeem tsim cov tshuaj tiv thaiv ntau dua thiab tso tawm 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.
Npaj Cells yog dab tsi?
Nco cov hlwb yog ib hom B hlwb sib txawv ntawm cov hlwb tsis zoo. Cov hlwb no yog lub luag haujlwm rau lub cim xeeb immunological. Yog li, lawv lub luag haujlwm tseem ceeb yog nco ntsoov cov antigens, rov qhib dua thiab tsim kev tiv thaiv kab mob sai sai thaum lawv ntsib cov antigen thib ob. Yog li ntawd, lub hlwb nco ua haujlwm hauv peb lub cev thaum tsim cov tshuaj tiv thaiv kab mob hauv nruab nrab. Memory B hlwb muaj ntau nyob rau hauv tib neeg spleen.
Daim duab 02: Lub Cev Muaj Zog
Nco lub hlwb muaj sia nyob ntev. Ntxiv mus, lawv rhiab heev rau tsawg npaum li cas ntawm antigen. Tsis tas li ntawd xwb, lawv lub cev tiv thaiv kab mob sai heev. Morphologically, lub hlwb nco zoo li cov hlwb tsis zoo B. Tab sis, lub hlwb nco nqa cov cim saum npoo, tsis zoo li cov hlwb tsis zoo. Tsis tas li ntawd, cov hlwb nco ua lub neej ntev dua li cov hlwb tsis zoo.
Dab tsi zoo sib xws ntawm Plasma Cells thiab Memory Cells?
- Plasma cells thiab nco hlwb yog ob hom kev tiv thaiv kab mob.
- Lawv originate los ntawm naïve B hlwb.
- Lawv yog cov qe ntshav dawb.
- Ob leeg tsim cov tshuaj tiv thaiv kab mob tiv thaiv kab mob txawv teb chaws.
Qhov txawv ntawm Plasma Cells thiab Memory Cells yog dab tsi?
Plasma hlwb thiab lub hlwb nco yog ob hom B lymphocytes sib txawv. Plasma hlwb tsim ntau cov tshuaj tiv thaiv kab mob, thaum lub hlwb nco nco txog cov tshuaj tiv thaiv kab mob thiab tsim cov tshuaj tiv thaiv kab mob thib ob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov ntshav plasma thiab cov hlwb nco. Tsis tas li ntawd, cov plasma hlwb muaj lub neej luv luv, thaum lub hlwb nco tau ntev.
Ntxiv mus, lwm qhov sib txawv ntawm cov ntshav plasma thiab cov hlwb nco yog tias cov hlwb nco tau muaj cov cim saum npoo, thaum lub plasma hlwb tsis ua.
Summary – Plasma Cells vs Memory Cells
Plasma hlwb yog tag nrho cov B lymphocytes uas muaj lub luag haujlwm rau cov tshuaj tiv thaiv kab mob ntau ntau thaum lub hlwb nco yog cov B hlwb sib txawv uas muaj lub luag haujlwm tswj kev tiv thaiv kab mob thiab tsim cov tshuaj tiv thaiv kab mob sai thaum raug tib antigen tom qab. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov ntshav plasma thiab cov hlwb nco. Plasma cells muaj lub neej luv luv, thaum lub hlwb nco tau ntev.
