Tib neeg kuj nug, nws txhais li cas los ua antigen tshwj xeeb?
Antigen Qhov tshwj xeeb. Cov antigens tshwj xeeb yog lees paub los ntawm cov tshuaj tiv thaiv zoo li no antigens lossis los ntawm T lymphocyte receptors tsim los khi rau tshwj xeeb kev txiav txim ntawm cov cell los yog cov ntaub so ntswg.
Ib sab saum toj no, dab tsi yog lub cev tiv thaiv kab mob? Cov tshuaj tiv thaiv kab mob tshwj xeeb yog tshwm sim los ntawm antigens. Cov tiv thaiv kab mob teb rau antigens los ntawm kev tsim cov cell uas ncaj qha tawm tsam cov kab mob, lossis los ntawm kev tsim cov protein tshwj xeeb hu ua tshuaj tiv thaiv kab mob. Cov tshuaj tiv thaiv txuas mus rau ib qho antigen thiab nyiam cov hlwb uas yuav engulf thiab rhuav tshem cov kab mob.
Ntxiv mus, dab tsi yog lub cev tiv thaiv kab mob tshwj xeeb?
Lub adaptive tiv thaiv kab mob , kuj hu ua tau tiv thaiv kab mob los yog, tsis tshua muaj, raws li cov kev tiv thaiv kab mob tshwj xeeb , yog subsystem ntawm tag nrho tiv thaiv kab mob uas yog tsim los ntawm cov kws tshwj xeeb tshwj xeeb, cov kab mob hauv lub cev thiab cov txheej txheem uas tshem tawm cov kab mob lossis tiv thaiv lawv txoj kev loj hlob.
Dab tsi yog qhov txawv ntawm kev tiv thaiv tshwj xeeb thiab tsis tshwj xeeb?
nonspecific tiv thaiv yog yam uas tiv thaiv lub cev los ntawm ntau yam kab mob, kab mob, thiab kab mob. Kev tiv thaiv tshwj xeeb yog yam uas tiv thaiv lub cev los ntawm tshwj xeeb kab mob.
