Cov qe ntshav dawb ua lub luag haujlwm tseem ceeb hauv ob qho tib si innate thiab yoog raws kev tiv thaiv kab mob. Cov yoog raws kev tiv thaiv kab mob yog kho los ntawm cov kab mob tiv thaiv kab mob hu ua cov lymphocytes . Cov no yog B thiab T cells. B cells zais cia tshuaj tiv thaiv , tshwj xeeb cov protein molecules uas khi rau cov kab mob tshwj xeeb.
Ntxiv mus, puas yog cov tshuaj tiv thaiv ib feem ntawm lub cev tiv thaiv kab mob?
Qhov thib ob, ob qho tib si innate thiab kev yoog raws tiv thaiv kab mob kuj xav tau ntau yam tshuaj yaj yeeb pom hauv ntshav thiab lwm yam kua hauv lub cev. Cov no yog cov protein zoo li cov enzymes, tshuaj tiv thaiv thiab luv amino amino chains. Cov tshuaj no yog rau kev tiv thaiv kev dag ntxias (los ntawm Latin lub ntsiab lus lom zem: "kua").
Ib tus kuj tseem yuav nug, puas yog qhov mob los yog hloov pauv? Kev mob ua lub luag haujlwm tseem ceeb hauv kev tswj cov kab mob thiab hauv kev hloov pauv tom ntej yoog raws kev tiv thaiv kab mob. Kev lig kev cai, innate kev tiv thaiv kab mob tau piav qhia raws li cov lus teb sai sai tshwm sim los ntawm cov generic thiab tsis hais tshwj xeeb uas txhais tau tias tsis muaj peev xwm nco tau.
Ua qhov no hauv kev txiav txim siab, dab tsi yog qhov sib txawv ntawm lub cev thiab lub cev tiv thaiv kab mob sib txawv?
Tsis muaj kev tiv thaiv yog ib yam uas twb muaj lawm hauv lub cev. Kev tiv thaiv kev tiv thaiv yog tsim teb kom raug rau cov khoom txawv teb chaws. Thaum ua haujlwm tawm tsam ib hom antigen tshwj xeeb, tus kev tiv thaiv tseem nyob thoob plaws lub neej.
Puas yog interferons innate lossis hloov pauv?
Hom I IFNs (IFN-I) yog cytokines, uas ua lub luag haujlwm tseem ceeb hauv innate thiab yoog raws tiv thaiv kab mob ntawm cov vertebrates. Hauv qhov tseem ceeb, IFN-Kuv raug ntxias thiab zais cia thaum tus tswv tsev paub txog kab mob nucleic acids thiab tiv thaiv lwm lub cell tiv thaiv kev kis tus kab mob los ntawm kev txhawb cov tshuaj tiv thaiv kab mob.
Pom zoo:
Agar yog dab tsi siv rau kev sim tshuaj tiv thaiv kab mob tiv thaiv kab mob?
Müeller-Hinton agar nquag siv hauv qhov tshuaj tiv thaiv kab mob tiv thaiv kab mob no
Cov tshuaj tiv thaiv kab mob pab tiv thaiv kab mob li cas?
Cov tshuaj tiv thaiv, tseem hu ua immunoglobulins, yog Y-zoo li cov proteins uas tsim los ntawm lub cev tiv thaiv kab mob los pab tiv thaiv cov neeg nkag los ntawm kev ua phem rau lub cev. Thaum pom cov tshuaj antigen hauv lub cev, lub cev tiv thaiv kab mob yuav tsim cov tshuaj tiv thaiv los ua cim antigen rau lub cev kom rhuav tshem
Yuav ua li cas thiaj txo tau cov tshuaj tiv thaiv kab mob tiv thaiv kab mob?
Yuav ua li cas thiaj li txo qis kev kis tshuaj tiv thaiv kab mob Tsis txhob siv tshuaj tua kab mob los kho kab mob, xws li khaub thuas, khaub thuas, hnoos los yog mob caj pas. Siv tshuaj tua kab mob tsuas yog thaum kws kho mob sau ntawv rau lawv. Thaum koj tau txais tshuaj tua kab mob, noj tag nrho daim ntawv tshuaj txawm tias koj nyob zoo los
Vim li cas cov kab mob hloov pauv tshuaj tiv thaiv kab mob?
Cov tshuaj tiv thaiv kab mob evolve ib txwm los ntawm kev xaiv ntuj los ntawm kev hloov pauv hloov pauv, tab sis nws kuj tuaj yeem tsim kho los ntawm kev siv cov kev ntxhov siab hloov mus rau cov pej xeem. Cov tshuaj tua kab mob yog ib puag ncig siab; cov kab mob uas muaj kev hloov pauv uas tso cai rau lawv muaj sia nyob yuav nyob rau qhov rov tsim dua tshiab
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
