Qhov sib txawv tseem ceeb ntawm cell mediated thiab antibody mediated immunity yog tias cell mediated immunity rhuav tshem cov kab mob sib kis ntawm cell lysis los ntawm cytokines, tsis muaj cov tshuaj tiv thaiv kab mob, thaum cov tshuaj tiv thaiv kab mob kho cov tshuaj tiv thaiv kab mob los ntawm kev tsim cov tshuaj tiv thaiv antigens.
Cell mediated immunity thiab antibody mediated immunity yog ob hom kev tiv thaiv thawj zaug uas tshwm sim hauv peb lub cev. Cell mediated immunity ua haujlwm tawm tsam intracellular pathogens. Yog li, nws ua haujlwm hauv cov kab mob uas muaj kab mob thiab rhuav tshem cov kab mob los ntawm kev tso cytokines. Hauv qhov sib piv, cov tshuaj tiv thaiv kab mob sib haum xeeb ua haujlwm tawm tsam cov kab mob hauv lub cev los ntawm kev tsim cov tshuaj tiv thaiv kab mob tiv thaiv cov antigens uas muaj nyob sab nraum cov kab mob los yog dawb ncig hauv cov ntshav. Ntxiv mus, B lymphocytes tsuas yog nqa tawm cov tshuaj tiv thaiv kab mob sib kis thaum T lymphocytes nqa tawm kev tiv thaiv kab mob ntawm tes.
Cell Mediated Immunity yog dab tsi?
Cell mediated immunity yog ib hom kev tiv thaiv kab mob thawj zaug uas ua haujlwm hauv peb lub cev. Cell mediated immunity tsis induce tsim cov tshuaj tiv thaiv. Nws tshwm sim los ntawm kev tso tawm ntau yam cytokines thiab ua kom phagocytes. Cell mediated immunity ua haujlwm tawm tsam cov kab mob hauv lub cev xws li kab mob thiab kab mob. Thaum tus kab mob nkag mus rau hauv lub cell thiab kis mus rau nws, antibody mediated tiv thaiv tsis tuaj yeem txheeb xyuas nws. Li no, cell mediated immune teb tuaj rau hauv kev ua si thiab tua cov kab mob ntawm tes ua ntej cov kab mob sib npaug hauv cov hlwb.
Daim duab 01: Cell Mediated Immunity
T lymphocytes yog lub cev tiv thaiv kab mob loj uas ua rau lub cev tiv thaiv kab mob sib kis. Naïve T cells qhib thiab hloov mus rau hauv effector T hlwb tom qab ntsib cov kab mob antigen-presenting (APCs). Helper T hlwb tso tawm cytokines uas pab qhib T hlwb los khi rau cov kab mob 'MHC-antigen complex thiab sib txawv T cell rau hauv cytotoxic T cell. Cytotoxic T hlwb ces ua rau cov kab mob kis mus rau apoptosis lossis cell lysis. Tsis tas li ntawd, cytokines nrhiav cov neeg tua neeg ntuj thiab phagocytes los rhuav tshem cov kab mob. Nyob rau hauv txoj kev no, cell mediated tiv thaiv teb rau cov kab mob kis, graft rejection, mob o thiab qog tiv thaiv kab mob.
Antibody Mediated Immunity yog dab tsi?
Antibody mediated immunity, raws li lub npe qhia, tshwm sim los ntawm kev tsim cov tshuaj tiv thaiv. Nws tshwj xeeb teb rau cov antigens uas muaj kev ywj pheej los yog nthuav tawm sab nraum cov kab mob. Thaum ib qho antigen nkag mus rau hauv peb cov ntshav nrog kev pab ntawm T cells, B lymphocytes sib txawv rau hauv cov ntshav plasma. Plasma hlwb proliferate, thiab tag nrho cov proliferated plasma hlwb tsim cov tshuaj tiv thaiv tshwj xeeb tiv thaiv cov antigens. Antibodies khi nrog antigens thiab neutralize los yog deactivate lawv los yog ua rau lysis.
Daim duab 02: Antibody Mediated Immunity
Cov tshuaj tiv thaiv yog immunoglobulin proteins. Muaj tsib hom tshuaj tiv thaiv xws li IgA, IgG, IgM, IgE thiab IgD. IgG yog hom tshuaj tiv thaiv ntau tshaj plaws. Antibodies txo qis tom qab lawv deactivate antigens. Txawm li cas los xij, B lymphocytes tsim cov hlwb nco thaum lawv ntsib ib qho antigen. Cov hlwb nco no tsim cov plasma hlwb thiab cov tshuaj tiv thaiv kab mob sai thiab mob siab rau thaum peb raug tib antigen thib ob. Yog li, antibody mediated immunity muab kev tiv thaiv ntev ntev rau cov antigens tshwj xeeb.
Dab tsi zoo sib xws ntawm Cell Mediated thiab Antibody Mediated Immunity?
- Cell mediated thiab antibody mediated immunity yog ob pawg ntawm kev tiv thaiv kab mob.
- Lawv yog cov txheej txheem tiv thaiv thawj.
- Pab T cells pab ob hom kev tiv thaiv kab mob.
- Ob hom kev tiv thaiv kab mob feem ntau tshwm sim nyob rau hauv vivo, thiab ob lo lus teb feem ntau ua haujlwm sib koom ua ke.
Qhov txawv ntawm Cell Mediated thiab Antibody Mediated Immunity yog dab tsi?
Cell mediated tiv thaiv yog yooj yim los ntawm T lymphocytes los ntawm kev tso tawm ntawm cytokines thaum cov tshuaj tiv thaiv kab mob sib kis tau yooj yim los ntawm B lymphocytes los ntawm kev tsim cov tshuaj tiv thaiv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cell mediated thiab antibody mediated immunity. Cell mediated immunity ua hauj lwm tawm tsam intracellular pathogens thaum antibody mediated kev tiv thaiv ua hauj lwm tawm tsam extracellular pathogens. Tsis tas li ntawd, cell mediated immunity tsim cov lus teb qeeb, thaum antibody mediated immunity tsim cov lus teb sai. Qhov no kuj yog qhov sib txawv ntawm cell mediated thiab antibody mediated immunity.
Cov hauv qab no infographic qhia txog qhov sib txawv ntawm cell mediated thiab antibody mediated immunity.
Summary – Cell Mediated vs Antibody Mediated Immunity
Cell mediated immunity thiab antibody mediated immunity yog ob pawg ntawm kev hloov kho lub cev. Antibody mediated immunity yog lub hauv paus tiv thaiv kab mob uas ua haujlwm tawm tsam cov kab mob extracellular. Nws yog tsuas yog yooj yim los ntawm B lymphocytes los ntawm kev tsim cov tshuaj tiv thaiv kab mob. Hauv qhov sib piv, cell mediated immunity yog thawj qhov kev tiv thaiv uas ua haujlwm tawm tsam cov kab mob intracellular. Nws yog tsuas yog yooj yim los ntawm T lymphocytes ntawm cytokine tso tawm. Helper T cells pab ob leeg cell mediated, thiab antibody mediated immunity. Yog li, qhov no yog cov lus piav qhia luv luv ntawm qhov sib txawv ntawm cell mediated thiab antibody mediated immunity.
