Xovtooj - kev kho kom haum xeeb (CMI) yog tiv thaiv kab mob teb tias ua tsis koom nrog cov tshuaj tiv thaiv kab mob tab sis cuam tshuam nrog kev ua kom macrophages thiab NK- hlwb , tsim cov antigen-specific cytotoxic T-lymphocytes, thiab tso tawm ntau yam cytokines teb rau antigen.
Ua qhov no hauv kev txiav txim siab, lub luag haujlwm ntawm kev tiv thaiv kab mob hauv xov tooj ntawm tes yog dab tsi?
Xovtooj - kev kho kom haum xeeb tau hais qhia feem ntau ntawm cov kab mob me me uas muaj sia nyob hauv phagocytes thiab cov kab mob me me uas kis tsis yog-phagocytic hlwb . Nws yog qhov muaj txiaj ntsig tshaj plaws hauv kev tshem tawm tus kab mob hlwb , tab sis kuj tseem koom nrog tiv thaiv cov kab mob hu ua fungi, protozoans, qog noj ntshav, thiab kab mob intracellular.
Kuj Paub, dab tsi yog cov kauj ruam hauv xov tooj ntawm tes kho kom haum xeeb tiv thaiv kab mob? Thawj zaug kauj ruam ntawm ntawm tes - kho cov lus teb tiv thaiv kab mob yog kev ua kom muaj antigen nthuav tawm hlwb : TH1 ua ntawm tes ntsib qhov tsis txaus siab tus kab mob antigen nthuav tawm ntawm tes , thiab lees paub MHC II-txwv antigen ntawm nws saum npoo.
Xav txog qhov no, kev tiv thaiv kab mob tiv thaiv kab mob ua haujlwm zoo li cas?
Kev tso dag tiv thaiv kab mob lus teb yog kho kom haum xeeb los ntawm tshuaj tiv thaiv kab mob cov molecules uas zais los ntawm cov ntshav ntshav. Txhawm rau nkag mus rau cov cell, cov kab mob thiab cov kab mob intracellular khi rau cov molecules tshwj xeeb ntawm lub hom phiaj ntawm tes. Antibodies uas khi rau cov kab mob tuaj yeem tiv thaiv qhov no thiab tau hais kom ua rau nruab nrab cov kab mob.
Cell tiv thaiv kab mob tiv thaiv kab mob thiab tiv thaiv kev dag ntxias yog dab tsi?
Humoral Immunity : Humoral tiv thaiv yog kho kom haum xeeb los ntawm T. hlwb , IB hlwb , thiab macrophages. Cell Tiv Thaiv Kev Tiv Thaiv Kab Mob : Cell tiv thaiv kev tiv thaiv kab mob yog kho kom haum xeeb los ntawm tus pab T. hlwb , cytotoxic T. hlwb , neeg tua neeg. hlwb , thiab macrophages. Ua. Humoral Immunity : Cov humoral tiv thaiv ua haujlwm ntawm cov kab mob sab nraud thiab lawv cov co toxins

Dab tsi yog txhais los ntawm kev tiv thaiv kab mob tiv thaiv kab mob?
Kev tshuaj tiv thaiv kab mob tiv thaiv kab mob tau siv los txiav txim siab tias cov tshuaj tua kab mob tshwj xeeb tshwj xeeb cov kab mob tshwj xeeb lossis kab mob hu ua fungus. Feem ntau, qhov kev sim no ua tiav Gram Stain thiab kab lis kev cai, cov txiaj ntsig uas tau txais sai dua
Dab tsi yog kev tiv thaiv kab mob tiv thaiv kab mob hauv microbiology?
Kev tiv thaiv kev tiv thaiv yog ob txoj hauv kev cuam tshuam nrog kev tiv thaiv tsis zoo (cov tshuaj tiv thaiv tsim los ntawm B cells) thiab kev tiv thaiv ntawm tes (T cells qhia tawm tsam cov kab mob hauv hlwb). Antigens, tseem hu ua immunogens, yog cov lwg me me uas qhib kev tiv thaiv kev tiv thaiv
Kev tiv thaiv kab mob thiab kev tiv thaiv kab mob yog dab tsi?
Lub cev tiv thaiv kab mob yog lub network nyuaj ntawm cov cell thiab cov protein uas tiv thaiv lub cev tiv thaiv kab mob. Lub cev tiv thaiv kab mob khaws cov ntaub ntawv ntawm txhua tus kab mob (microbe) nws tau swb lawm yog li nws tuaj yeem lees paub thiab rhuav tshem cov kab mob sai sai yog tias nws nkag mus rau hauv lub cev dua
Cell tiv thaiv kev tiv thaiv kab mob txhais tau li cas?
Los ntawm Wikipedia, phau ntawv txhais lus pub dawb. Kev tiv thaiv kab mob ntawm tes yog kev tiv thaiv kab mob uas tsis koom nrog cov tshuaj tiv thaiv kab mob. Qhov tseeb, kev tiv thaiv kab mob hauv nruab nrab ntawm tes yog ua kom muaj phagocytes, antigen-specific cytotoxic T-lymphocytes, thiab tso tawm ntau yam cytokines hauv kev teb rau antigen
Cov tshuaj tiv thaiv ua haujlwm li cas lawv ua haujlwm tiv thaiv kab mob thiab kab mob?
Cov tshuaj tiv thaiv ua haujlwm los ntawm kev cob qhia lub cev tiv thaiv kab mob kom paub thiab tawm tsam cov kab mob, xws li kab mob lossis kab mob. Txhawm rau ua qhov no, qee cov molecules los ntawm cov kab mob yuav tsum tau nkag rau hauv lub cev kom ua rau muaj kev tiv thaiv kab mob. Cov molecules no hu ua antigens, thiab lawv muaj nyob rau tag nrho cov kab mob thiab cov kab mob
