Cov lus teb hauv lub cev hu rau kev hloov pauv lub cev tiv thaiv kab mob rau hauv kev ua si, thiab ob leeg ua haujlwm ua ke txhawm rau tshem tawm cov kab mob(Daim duab 24-1). Tsis zoo li cov lus teb hauv lub cev tsis muaj zog, cov lus teb hloov kho tau tshwj xeeb rau cov kab mob tshwj xeeb uas ua rau lawv. Lawv kuj tuaj yeem muab kev tiv thaiv ntev ntev.
Kev sib raug zoo ntawm lub cev thiab lub cev tiv thaiv kab mob yog dab tsi?
Lub cev tsis muaj zog tiv thaiv kab mob harnesses receptors uas lees paub cov qauv kev tiv thaiv kab mob thiab nrog rau cov kev paub tshwj xeeb thiab kev nco txog kev tiv thaiv kev tiv thaiv, lawv qhov kev sib cuam tshuam yog pov thawj los ntawm cov luag haujlwm hauv tiam neeg thiab kev tswj hwm. ntawm kev tiv thaiv kab mob.
Thaum twg lub cev thiab kev tiv thaiv kev tiv thaiv ua haujlwm ua ke?
INNATE THIAB ADAPTIVE IMMUNITY
Muaj ob lub subsystems hauv lub cev tiv thaiv kab mob, hu ua innate (tsis yog tshwj xeeb) lub cev tiv thaiv kab mob thiab kev hloov pauv (tshwj xeeb) tiv thaiv kab mob. Ob leeg ntawm cov subsystems no yog sib txuas thiab ua hauj lwm ua ke thaum twg cov kab mob lossis cov khoom tsis zoo ua rau lub cev tiv thaiv kab mob.
Kev tiv thaiv kab mob hauv lub cev li cas txhawb kev tiv thaiv kev tiv thaiv?
Kev tiv thaiv kab mob yoog tau pib thaum lub cev tiv thaiv kab mob hauv lub cev tsis tuaj yeem tshem tawm tus kab mob tshiab, thiab cov tshuaj tiv thaiv kab mob thiab cov tshuaj tiv thaiv kab mob ua kom muaj zog xa mus rau cov ntaub so ntswg lymphoid.
Peb hom kev tiv thaiv kab mob hauv lub cev yog dab tsi?
raws li kev tshwm simkev paub txog qhov sib txawv effector T-cell thiab innate lymphoid cell (ILC) kab, nws yog qhov tseeb tias cov kab mob hauv lub cev thiab kev hloov pauv hloov pauv mus rau hauv 3 hom loj ntawm cov cell-mediated effector tiv thaiv kab mob, uas peb xav kom categorize li hom 1, hom 2, thiab hom 3.
Pom zoo:
Puas yog lub cev tiv thaiv kab mob hauv lub cev puas tsim cov tshuaj tiv thaiv?
Lub cev tiv thaiv kab mob tau txais, nrog kev pab los ntawm lub cev hauv lub cev, tsim cov hlwb (tshuaj tiv thaiv kab mob) los tiv thaiv koj lub cev los ntawm ib tus neeg invader tshwj xeeb. Cov tshuaj tiv thaiv no yog tsim los ntawm cov hlwb hu ua B lymphocytes tom qab lub cev tau raug rau cov neeg ua phem.
Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?
Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).
Lub cev tiv thaiv kab mob ua haujlwm hauv lub cev li cas?
Lub Immune System Ua Haujlwm Li Cas? Thaum lub cev hnov cov tshuaj txawv teb chaws (hu ua antigens), lub cev tiv thaiv kab mob ua haujlwm kom paub txog cov antigens thiab tshem tawm ntawm lawv. B lymphocytes tau ua rau ua cov tshuaj tiv thaiv (tseem hu ua immunoglobulins).
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
Puas yog lub cev tiv thaiv kab mob ua haujlwm nrog lwm lub cev?
Kev Sib Tham Nrog Lwm Cov Txheej Txheem Lub cev tiv thaiv kab mob zoo li tub ceev xwm me me uas saib xyuas txhua lub cev thiab cov ntaub so ntswg hauv koj lub cev. Nws ua haujlwm zoo nrog lub circulatory system rau kev thauj mus los xav tau thiab lymphatic system rau tsim cov lymphocytes.
