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.
