Tom qab ntawd koj lub cev tuaj yeem tsim cov riam phom zoo tshaj plaws tiv thaiv cov neeg tawm tsam, uas tuaj yeem yog kab mob, kab mob lossis kab mob parasites. Lwm hom T - hlwb paub thiab tua tus kab mob hlwb ncaj qha Ib txhia pab B - hlwb ua cov tshuaj tiv thaiv kab mob, uas nthuav tawm thiab khi rau antigens. A T - ntawm tes (txiv kab ntxwv) tua mob qog noj ntshav ntawm tes (mauv).
Ntawm no, yuav ua li cas T cells pab B cells?
Pab T - hlwb txhawb B - hlwb ua cov tshuaj tiv thaiv kab mob thiab pab neeg tua neeg hlwb txhim kho Tua neeg T - hlwb ncaj qha tua hlwb uas twb tau kis los ntawm tus neeg txawv tebchaws tuaj txeeb chaw. T - hlwb kuj tseem siv cytokines ua cov xa xov lwg me me kom xa cov lus qhia tshuaj mus rau lwm qhov ntawm lub cev tiv thaiv kab mob kom nce nws cov lus teb.
Ib tus kuj yuav nug, qhov sib txawv ntawm T cells thiab B cells yog dab tsi? Ob leeg T cells thiab B cells raug tsim tawm hauv pob txha pob txha. Cov T hlwb tsiv mus rau thymus rau kev loj hlob. Lub ntsiab qhov sib txawv ntawm T cells thiab B cells yog li T hlwb tsuas tuaj yeem lees paub tus kab mob antigens sab nraum tus kab mob hlwb qhov twg B hlwb tuaj yeem paub qhov chaw antigens ntawm cov kab mob thiab kab mob.
Ib qho ntxiv, B cells thiab T cells ua dab tsi hauv kev tiv thaiv kab mob?
T hlwb koom nrog hauv ntawm tes -nruab nrab kev tiv thaiv , qhov chaw B hlwb feem ntau yog lub luag haujlwm rau kev dag ntxias kev tiv thaiv (ntsig txog cov tshuaj tiv thaiv). Cov muaj nuj nqi ntawm T hlwb thiab B hlwb yog kom lees paub qhov tshwj xeeb "tsis yog tus kheej" antigens, thaum lub sijhawm txheej txheem hu ua antigen nthuav qhia.
B thiab T cells paub txog cov antigens tshwj xeeb li cas?
B - hlwb muaj B - ntawm tes Cov neeg txais ntawm lawv qhov chaw uas tuaj yeem ua tau paub lab hom sib txawv ntawm antigens . T - hlwb ib yam muaj T - ntawm tes receptors uas kuaj pom antigen ntawm qhov chaw ntawm Antigen Qhia tawm hlwb . Cov antigens tau nthuav tawm rau cov T - hlwb los ntawm MHC- Antigen nyuaj.
Pom zoo:
Neuroglial cells yog dab tsi thiab lawv lub luag haujlwm yog dab tsi?
Cov hlwb uas tsim myelin, tiv thaiv, txhawb nqa, thiab tswj kev sib npaug hauv koj lub paj hlwb hu ua glial cells. Lawv kuj tseem raug hu ua neuroglia thiab txawm tias yooj yim dua glia. Hauv cov lus ntxaws ntxaws, neuroglia yog cov hlwb hauv koj lub paj hlwb uas tsis yog neurons
Qhov sib txawv ntawm tus pab T cells thiab cytotoxic T cells yog dab tsi?
T hlwb yog li ntawd hu ua vim lawv feem ntau tsim nyob rau hauv lub thymus. Raws li cov npe hais tias pab T hlwb 'pab' lwm lub hlwb ntawm lub cev tiv thaiv kab mob, thaum cytotoxic T hlwb tua cov kab mob kis kab mob thiab qog. Tsis zoo li cov tshuaj tiv thaiv kab mob, TCR tsis tuaj yeem khi cov tshuaj tiv thaiv ncaj qha
Lub luag haujlwm ntawm T cells thiab B cells yog dab tsi?
T cells koom nrog hauv kev tiv thaiv kab mob ntawm tes, qhov B hlwb feem ntau yog lub luag haujlwm rau kev tiv thaiv kev dag ntxias (hais txog cov tshuaj tiv thaiv). Kev ua haujlwm ntawm T hlwb thiab B hlwb yog kom paub txog cov 'tsis yog tus kheej' antigens, thaum lub sijhawm ua haujlwm hu ua antigen nthuav qhia
Dab tsi yog qhov sib txawv ntawm glial cells thiab lawv cov haujlwm?
Hom Glia Glial hlwb ntawm (a) hauv nruab nrab paj hlwb muaj xws li oligodendrocytes, astrocytes, ependymal hlwb, thiab microglial hlwb. Oligodendrocytes tsim lub myelin sheath ncig axons. Astrocytes muab cov as -ham rau cov neurons, tswj hwm lawv ib puag ncig sab nraud, thiab muab kev txhawb nqa yam ntxwv
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
