Qhov sib txawv tseem ceeb ntawm T lymphocytes thiab B lymphocytes yog tias T lymphocytes pib hauv cov pob txha pob txha thiab loj hlob hauv thymus thaum B lymphocytes pib thiab loj hlob hauv cov pob txha pob txha.
Lub ntsiab ntawm ob hom hlwb hauv cov ntshav yog cov qe ntshav liab (RBC) thiab cov qe ntshav dawb (WBC). RBC nqa thiab thauj oxygen thaum WBC pab hauv kev tiv thaiv mechanisms. Muaj ob lub ntsiab ntawm cov qe ntshav dawb li granulocytes thiab agranulocytes. Granulocytes muaj granules hauv cytoplasm thaum agranulocytes tsis muaj granules hauv cytoplasm. Agranulocytes muaj ob hom loj: lymphocytes thiab monocytes. Lymphocytes zoo ib yam li cov tsos, tab sis lawv muaj cov haujlwm sib txawv. Raws li lawv txoj haujlwm, lymphocytes tau muab faib ua T lymphocytes thiab B lymphocytes. Ob leeg yog ib qho tseem ceeb los tiv thaiv kev kis kab mob. Lub hom phiaj tseem ceeb ntawm tsab xov xwm no yog los tham txog qhov sib txawv ntawm T lymphocytes thiab B lymphocytes.
YT Lymphocytes yog dab tsi?
T lymphocytes yog hom lymphocytes, thiab kuj yog hom qe ntshav dawb koom nrog hauv kev tiv thaiv kab mob ntawm tes. 80% ntawm cov lymphocytes ncig hauv cov ntshav yog T lymphocytes. Lawv yog agranulocytes. T lymphocytes tsim nyob rau hauv cov pob txha pob txha. Tom qab ntawd, lawv tsiv mus rau thymus rau maturation. Li no, lub npe "T cells" tau muab rau cov hlwb no.
Daim duab 01: T Lymphocyte
Muaj peb hom T lymphocytes: pab T hlwb, cytotoxic T hlwb, thiab suppressor T hlwb. Helper T hlwb indirect induce lub cev tiv thaiv kab mob los ntawm secreting cytokines. Cytotoxic T lymphocytes ncaj qha tua cov kab mob kis los ntawm phagocytosis thaum cov tshuaj tua kab mob T-hlwb txwv tsis pub cov tshuaj tiv thaiv kab mob hauv lub cev.
YB Lymphocytes yog dab tsi?
B lymphocytes lossis B hlwb yog hom thib ob ntawm lymphocytes koom nrog hauv kev tiv thaiv kab mob humoral lossis antibody-mediated immunity. Lawv kuj yog agranulocytes. B lymphocytes originates thiab loj hlob nyob rau hauv cov pob txha pob txha. Lawv suav txog 20% ntawm cov lymphocytes hauv cov ntshav.
Daim duab 02: Kev ua haujlwm ntawm B lymphocytes
Muaj ob hom B lymphocytes ua cov plasma hlwb thiab cov hlwb nco. Plasma cells qhib thiab tso cov tshuaj tiv thaiv kab mob thaum ntsib cov antigen. Secreted antibodies ces neutralize cov antigens. Cov tshuaj tiv thaiv kab mob tshwj xeeb rau tus kab mob. Qhov ntawd txhais tau tias; Cov kab mob sib txawv yuav tsim cov tshuaj tiv thaiv sib txawv.
Dab tsi zoo sib xws ntawm T Lymphocytes thiab B Lymphocytes?
- Ob leeg T lymphocytes thiab B lymphocytes yog cov qe ntshav dawb.
- Lawv yog agranulocytes (tsis muaj granules hauv cytoplasm).
- Tsis tas li, lawv yog cov tshuaj tiv thaiv kab mob tshwj xeeb (lub cev tiv thaiv kab mob tuaj yeem txheeb xyuas cov neeg tawm tsam thiab tawm tsam).
- Thiab, lawv koom nrog kev tiv thaiv kev tiv thaiv ntawm peb lub cev.
- Ntxiv mus, ob hom kis tau los ntawm cov ntshav.
- Thiab, ob qho tib si yog tsim los ntawm cov pob txha pob txha tab sis paub tab nyob rau ntau qhov chaw.
Qhov txawv ntawm T Lymphocytes thiab B Lymphocytes yog dab tsi?
T lymphocytes thiab B lymphocytes yog ob hom lymphocytes nyob hauv peb cov ntshav. T lymphocytes koom nrog hauv cell-mediated tiv thaiv thaum B lymphocytes koom nrog hauv kev tiv thaiv kab mob sib kis. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm T lymphocytes thiab B lymphocytes. Tsis tas li ntawd, T lymphocytes tsim cytokines thaum B lymphocytes tsim cov tshuaj tiv thaiv. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm T lymphocytes thiab B lymphocytes yog lawv qhov chaw loj hlob. T lymphocytes mature nyob rau hauv lub thymus thaum B lymphocytes mature nyob rau hauv cov pob txha pob txha.
Ntxiv mus, muaj peb hom T lymphocytes ua pab t hlwb, cytotoxic T hlwb, thiab suppressor T hlwb thaum muaj ob hom B lymphocytes li ntshav hlwb thiab nco hlwb. Tsis tas li ntawd, T lymphocytes txav mus rau qhov chaw kis kab mob thaum B lymphocytes tsis txav mus. Yog li, peb tuaj yeem xav txog qhov no kuj yog qhov sib txawv ntawm T lymphocytes thiab B lymphocytes. Tsis tas li ntawd, 80% ntawm cov lymphocytes nyob rau hauv cov ntshav yog T lymphocytes thaum tsuas yog 20% yog B lymphocytes. Li no, qhov no kuj yog qhov sib txawv ntawm T lymphocytes thiab B lymphocytes.
Cov duab hauv qab no nthuav tawm cov ntaub ntawv ntau ntxiv ntawm qhov sib txawv ntawm T lymphocytes thiab B lymphocytes piv.
Summary – T Lymphocytes vs B Lymphocytes
Lymphocytes yog hom qe ntshav dawb tseem ceeb hauv kev tiv thaiv kab mob hauv peb lub cev. T lymphocytes koom nrog hauv cell-mediated tiv thaiv thaum B lymphocytes koom nrog hauv kev tiv thaiv kab mob humoral. Cov pob txha pob txha tsim ob leeg T lymphocytes thiab B lymphocytes. Txawm li cas los xij, T lymphocytes paub tab hauv thymus thaum B lymphocytes paub tab hauv cov pob txha pob txha. Muaj peb hom T lymphocytes li pab T hlwb, suppressor T hlwb, thiab cytotoxic T hlwb. Helper T cells qhib cytotoxic T hlwb thiab B hlwb thaum cytotoxic T hlwb tua cov kab mob los ntawm phagocytosis. Ntawm qhov tod tes, B lymphocytes tsim thiab zais cov tshuaj tiv thaiv kab mob txhawm rau txhawm rau ua kom lub cev tiv thaiv kab mob los rhuav tshem cov antigens. B lymphocytes kuj muaj ob hom tseem ceeb: plasma hlwb thiab nco hlwb. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm T lymphocytes thiab B lymphocytes.
