Thaum lub innate immune teb yog tam sim no, cov adaptive immune teb tsis yog Txawm li cas los xij, cov txiaj ntsig ntawm adaptive immune teb yog lub sijhawm ntev, tshwj xeeb, thiab txhawb nqa lub sijhawm ntev los ntawm kev nco T cells.
Ntawm no, dab tsi yog qhov sib txuas ntawm kev xeeb tub thiab tiv thaiv kev tiv thaiv?
Dendritic cells (DC) yog lub cim tshwj xeeb ntawm cov cell uas muaj peev xwm ntxias tau thawj tiv thaiv kab mob teb. Raws li ib feem ntawm cov lub cev tsis muaj zog system, DC teeb tsa thiab xa cov ntaub ntawv los ntawm ntiaj teb sab nraud mus rau lub hlwb ntawm tiv thaiv kab mob qhov system.
Qhov thib ob, dab tsi ua kom muaj kev tiv thaiv los ntawm tus kheej thiab hloov pauv? Tsis muaj kev tiv thaiv (tseem hu ua ntuj lossis haiv neeg kev tiv thaiv ) muab txoj kab kev tiv thaiv kab mob thaum ntxov. Qhov tshwj xeeb Cheebtsam ntawm kev tiv thaiv kev tiv thaiv yog cov hlwb hu ua lymphocytes thiab lawv cov khoom zais, xws li cov tshuaj tiv thaiv kab mob.
Tsuas yog li ntawd, cov hlwb twg koom nrog hauv lub cev thiab kev tiv thaiv kab mob?
Ntau yam ntawm hlwb hauv lub cev tsis muaj zog system (xws li dendritic hlwb , macrophages, mast hlwb , neutrophils, basophils thiab eosinophils) tsim cytokines lossis cuam tshuam nrog lwm yam hlwb ncaj qha nyob rau hauv thiaj li yuav qhib lub adaptive tiv thaiv kab mob qhov system.
Ib qho piv txwv ntawm kev tiv thaiv hauv lub cev yog dab tsi?
Piv txwv ntawm innate tiv thaiv kab mob suav nrog: hnoos reflex Enzymes hauv kua muag thiab cov tawv nqaij. Cov hnoos qeev, uas ntxiab cov kab mob thiab cov me me. Tawv nqaij.

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
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Dab tsi yog qhov sib txawv ntawm lub cev xeeb tub thiab cov lus teb tiv thaiv kab mob?
Kev tiv thaiv tsis tau yog ib yam uas twb muaj lawm hauv lub cev. Kev tiv thaiv kev tiv thaiv tau tsim los teb rau kis tau cov khoom txawv teb chaws. Thaum ua kom muaj zog tiv thaiv ib hom antigen, kev tiv thaiv tseem nyob thoob plaws lub neej
Dab tsi yog kev sib raug zoo ntawm kev sib raug zoo ntawm deviance thiab stigma?
'Stigma' yog txheej txheem los ntawm cov zej zog hauv zej zog 'tshem tawm' cov tswv cuab uas ua txhaum lawv cov kev xav tau thiab cov qauv. Ib tus neeg ua txhaum ntau dua thiab cov qauv ntawm ib puag ncig kev sib raug zoo yog 'deviant'
Dab tsi yog kev sib raug zoo ntawm cov tshuaj tiv thaiv kab mob thiab B hlwb?
Teb Chaws Asmeskas: Dab tsi yog qhov kev sib raug zoo ntawm cov tshuaj tiv thaiv kab mob thiab B hlwb? Thaum B cell receptor khi nws cov cognate antigen (antigen tau tsim rau qhov tshwj xeeb B cell) nws tau hloov pauv thiab tuaj yeem tso daim ntawv soluble ntawm tus txais ntawd. Daim ntawv soluble ntawm tus neeg txais khoom paub tias yog tshuaj tiv thaiv kab mob
