Cov innate tiv thaiv kab mob qhia cov kev tiv thaiv kab mob tiv thaiv kab mob thaum lub sijhawm rau pab mount tiv thaiv. Nws ua qhov no los ntawm kev tshaj tawm ob hom kev hloov pauv ntawm phagocyte nto uas qhib lub kev tiv thaiv kab mob tiv thaiv kab mob . Qhov no ceeb toom rau kev tiv thaiv kab mob tiv thaiv kab mob thiab tso cai rau cov cell hu ua T cells rau paub txog tus kab mob.
Ib yam li ntawd, kev sib raug zoo ntawm lub cev thiab lub cev tiv thaiv kab mob yog dab tsi?
Thaum lub innate immune teb yog tam sim no, cov adaptive immune teb tsis yog Txawm li cas los xij, cov txiaj ntsig ntawm kev tiv thaiv kab mob tiv thaiv kab mob yog lub sijhawm ntev, tshwj xeeb, thiab txhawb nqa lub sijhawm ntev los ntawm kev nco T cells.
Qhov thib ob, qhov txawv ntawm qhov qub thiab qhov kev tiv thaiv kab mob hloov pauv dab tsi? Tsis muaj kev tiv thaiv yog ib yam uas twb muaj lawm hauv lub cev. Kev tiv thaiv kev tiv thaiv yog tsim nyob rau hauv lus teb kom raug ib yam khoom txawv teb chaws. Thaum ua haujlwm tawm tsam ib hom antigen tshwj xeeb, tus tiv thaiv kab mob tseem nyob thoob plaws lub neej.
Tom qab ntawd, lo lus nug yog, yuav ua li cas lub cev tiv thaiv kab mob hauv lub cev ua kom lub cev tiv thaiv kab mob hloov tau?
Cov lub cev tsis muaj zog muaj cov cell uas kuaj pom tias muaj peev xwm ua rau muaj antigens, thiab tom qab ntawd qhia rau kev tiv thaiv kab mob tiv thaiv kab mob txog qhov muaj cov antigens no. Antigen-presenting cell (APC) yog ib qho tiv thaiv kab mob cell uas pom, nkag mus, thiab qhia rau adaptive immune teb txog tus kab mob.
Puas yog phagocytosis innate lossis tiv thaiv kev tiv thaiv?
Cov leukocytes uas muaj los suav nrog: cov kab mob tua neeg, cov qe mast, eosinophils, basophils; thiab phagocytic hlwb muaj xws li macrophages, neutrophils, thiab dendritic hlwb , thiab ua haujlwm hauv lub cev tiv thaiv kab mob los ntawm kev txheeb xyuas thiab tshem tawm cov kab mob uas tuaj yeem ua rau kis mob.
Pom zoo:
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
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
Dab tsi yog qhov tshuaj tiv thaiv kab mob tiv thaiv kab mob tam sim?
Cov tshuaj tiv thaiv kev hloov pauv tau txhais tias yog cov xwm txheej tsis zoo cuam tshuam nrog kev tso ntshav tag nrho lossis ib qho ntawm nws cov khoom. Cov tshuaj tiv thaiv tuaj yeem tshwm sim thaum lub sijhawm tso ntshav (mob ntshav tawm tsam) lossis hnub mus rau lub lis piam tom qab (kev hloov pauv tsis tu ncua) thiab tej zaum yuav yog immunologic lossis non-immunologic
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
