Key Difference – T Cells vs B Cells
cov qe ntshav dawb yog ib feem ntawm lub cev tiv thaiv kab mob. Cov hlwb no tawm tsam ntau hom kab mob txawv teb chaws nrog rau cov kab mob, kab mob, thiab co toxins uas ua rau tib neeg mob. Cov qe ntshav dawb tsawg hauv cov ntshav qhia tau tias lub cev tsis muaj zog. Muaj ob lub ntsiab ntawm cov qe ntshav dawb: phagocytes thiab lymphocytes. Lymphocytes yog ib hom qe ntshav dawb uas muaj lub ntsej muag puag ncig. Lymphocytes yog tas li tsim los ntawm qia hlwb ntawm cov pob txha pob txha. Lawv raug tso tawm mus rau hauv cov hlab ntsha thiab rau hauv lymphatic system. Lymphocytes yog peb hom tseem ceeb hu ua T hlwb, B hlwb, thiab cov cell killer ntuj. T hlwb mus rau lub thymus thiab ua rau cov hlwb paub tab thaum B hlwb nyob hauv cov pob txha pob txha thiab ua kom loj hlob. T hlwb thiab B hlwb yog cov cellular tseem ceeb ntawm lub cev tiv thaiv kab mob. Qhov sib txawv tseem ceeb ntawm T hlwb thiab B hlwb yog tias T hlwb tau koom nrog hauv kev tiv thaiv kab mob hauv cell-mediated thaum B hlwb yog lub luag haujlwm rau kev tiv thaiv kev lom zem. Cov tshuaj tiv thaiv kab mob tsis koom nrog hauv cell mediated tiv thaiv kab mob. Nws tshwm sim los ntawm kev ua kom phagocytes, antigen tshwj xeeb cytotoxic T lymphocytes, thiab cytokinins. Kev tiv thaiv humoral yog kho los ntawm cov tshuaj tiv thaiv kab mob thiab lwm yam ntxiv cov proteins thiab tshuaj tua kab mob peptides. Txawm li cas los xij, ob lub hlwb T thiab B hlwb ua haujlwm ua ke los tawm tsam tus kabmob.
T Cells yog dab tsi?
T hlwb lossis T lymphocytes yog subtypes ntawm lymphocytes. Lawv ua raws li kev tiv thaiv hlwb tiv thaiv kab mob. Lawv yog ib feem ntawm kev tiv thaiv kab mob. Lawv feem ntau koom nrog hauv cell mediated immunity uas tsis tshwm sim los ntawm kev tsim cov tshuaj tiv thaiv kab mob. T hlwb yog tsim nyob rau hauv cov pob txha pob txha. Tom qab ntawd lawv mus rau thymus thiab ua kom loj hlob. Cov T hlwb no tuaj yeem txawv ntawm lwm cov lymphocytes vim muaj T cell receptors ntawm T cell nto.
Daim duab 01: T lymphocyte
Muaj ntau hom T hlwb. Lawv yog cov pab T hlwb, nco T hlwb, killer T hlwb thiab suppressor T hlwb. Helper T hlwb koom tes nrog B hlwb hauv kev tsim cov tshuaj tiv thaiv kab mob thiab ua kom cov macrophages thiab o. Lub cim xeeb T hlwb tseem nyob hauv cov hlab ntshav los tiv thaiv kev kis kab mob yav tom ntej. Supressor T hlwb tiv thaiv cov ntaub so ntswg noj qab haus huv. Killer T cells tua cov kab mob kis ncaj qha.
B Cells yog dab tsi?
B hlwb, tseem hu ua B lymphocytes, yog ib qho subtype ntawm lymphocytes (cov qe ntshav dawb). Lawv koom nrog hauv cov tshuaj tiv thaiv kab mob adaptive. B hlwb tsim nyob rau hauv cov pob txha pob txha thiab ncig ntawm cov hlab ntsha. B hlwb tsim cov membrane khi cov proteins hu ua antibodies (immunoglobulins). Lawv nyob rau saum npoo ntawm B hlwb. Lawv tseem ceeb heev nyob rau hauv kev paub txog cov antigens tshwj xeeb uas nkag mus rau hauv lub cev. Antigens tuaj yeem yog kab mob, kab mob, tshuaj lom, thiab lwm yam. Cov tshuaj tiv thaiv uas tsim los ntawm B hlwb xaiv khi nrog cov antigens thiab tiv thaiv lawv nkag mus rau hauv cov tswv tsev. Thaum cov tshuaj tiv thaiv kab mob khi rau ib qho antigen, nws chij cov kab mob rau lub cev tiv thaiv kab mob rau kev puas tsuaj. Txhua B cell tsim cov tshuaj tiv thaiv uas yog tshwj xeeb rau nws. Cov tshuaj tiv thaiv sib txawv vim qhov sib txawv ntawm qhov sib txawv ntawm cov tshuaj tiv thaiv. Li no, thaum tag nrho cov b hlwb tsim ntau cov tshuaj tiv thaiv sib txawv, lawv tuaj yeem khi rau ntau lub hom phiaj antigens thiab tiv thaiv kab mob.
Daim duab 02: B cell
B hlwb muaj cov tshuaj tiv thaiv. Yog li ntawd, lawv tseem hu ua antigen nthuav tawm cov hlwb. Lawv kuj secrete cytokines. B hlwb thiab cov tshuaj tiv thaiv kab mob ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kab mob. Lawv qhov tsis tuaj yeem ua rau muaj kab mob tiv thaiv kab mob hnyav thiab tawm hauv lub cev mus rau hauv lub xeev uas muaj kev phom sij heev rau kev kis kab mob.
Dab tsi zoo sib xws ntawm T Cells thiab B Cells?
- B lymphocytes thiab T lymphocytes ua haujlwm ua ke los tiv thaiv kab mob.
- Ob lub hlwb yog cov qe ntshav dawb.
- Ob lub hlwb koom nrog hauv lub cev tiv thaiv kab mob.
- Ob hom cell yog tsim los ntawm cov pob txha pob txha.
Qhov txawv ntawm T Cells thiab B Cells yog dab tsi?

Summary – T Cells vs B Cells
Lymphocytes yog ib hom qe ntshav dawb ncig hauv cov ntshav. Qhov ntau tshaj ob hom lymphocytes yog T cell thiab B hlwb. B thiab T hlwb yog tsim nyob rau hauv cov pob txha pob txha. B hlwb nyob twj ywm hauv cov hlab ntsha thaum T hlwb nkag mus rau hauv thymus thiab loj hlob tuaj. B hlwb thiab T hlwb yog ob yam tseem ceeb hauv kev tiv thaiv kab mob. B hlwb koom nrog hauv kev tiv thaiv kab mob humoral thaum T hlwb koom nrog hauv cell mediated tiv thaiv. Qhov no yog qhov txawv ntawm T cells thiab B hlwb.
