B-lymphocytes tsim immunocompetence hauv cov pob txha.
B lymphocytes tsim lawv qhov kev tiv thaiv kab mob nyob qhov twg?
Cov lymphocytes no txhim kho kev tiv thaiv kab mob hauv cov kab mob hauv lub cev: thymus, rau T lymphocytes thiab bursa ntawm Fabricius (hauv cov noog), ntawm nws qhov sib npaug (hauv cov tsiaj txhu), rau B. lymphocytes.
B lymphocytes tsim ua dab tsi?
B lymphocytes ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kab mob tshwj xeeb los ntawm kev tsim cov tshuaj tiv thaiv. B lymphocytes paub txog cov antigens soluble ntawm immunoglobulins anched rau ntawm lawv qhov chaw thiab sib txawv rau hauv cov tshuaj tiv thaiv kab mob, hu uaplasma cells, muaj peev xwm secreting immunoglobulins.
YImmunocompetence ntawm lymphocytes yog dab tsi?
In reference to lymphocytes, immunocompetence txhais tau hais tias a B cell los yog T cell yog paub tab thiab paub txog antigens thiab tso cai rau ib tug neeg los txhim kho lub cev tiv thaiv kab mob.
YYuav ua li cas cov lymphocytes ua immunocompetent?
Lub hauv paus txheej txheem rau kev txhim kho lub cev tiv thaiv kab mob rau tus kheej-antigens tshwm sim thaum xaiv rau cov hlwb tsis muaj zog, khi rau tus kheej thaum T thiab B lymphocyte maturation. Txhua T lossis B lymphocytes uas paub txog yam tsis muaj kev phom sij txawv teb chaws lossis "tus kheej" antigens raug tshem tawmua ntej lawv tuaj yeem loj hlob mus rau hauv cov hlwb tiv thaiv kab mob.
Pom zoo:
Cov tshuaj tiv thaiv tam sim no puas tiv thaiv kab mob sib txawv?
2) qhov sib txawv tam sim no yog qhov sib txawv tshaj plaws ntawm COVID-19. Nws yog ze li ob zaug kis tau tus kab mob ua ntej thiab yuav ua rau mob hnyav dua. Txawm hais tias kev tshawb fawb qhia tias cov tshuaj tiv thaiv COVID-19 tsis tshua muaj txiaj ntsig zoo rau qhov sib txawv, cov tshuaj tiv thaiv tseem zoo li muab kev tiv thaiv COVID-19 hnyav.
Puas yog kev tiv thaiv kev tiv thaiv tsis sib txawv ntawm tus kheej?
Peb xav tias lub cev tiv thaiv kab mob ua tiav kev ntxub ntxaug tus kheej tsis yog tus kheej, thaum hloov pauv kev tiv thaiv, tsis yog los ntawm kev lees paub qhov sib txawv ntawm tus kheej thiab txawv teb chaws antigens, tab sis los ntawm kev pom qhov avidity ntawm T cell activation.
Puas yog lub cev tiv thaiv kab mob hauv lub cev puas tsim cov tshuaj tiv thaiv?
Lub cev tiv thaiv kab mob tau txais, nrog kev pab los ntawm lub cev hauv lub cev, tsim cov hlwb (tshuaj tiv thaiv kab mob) los tiv thaiv koj lub cev los ntawm ib tus neeg invader tshwj xeeb. Cov tshuaj tiv thaiv no yog tsim los ntawm cov hlwb hu ua B lymphocytes tom qab lub cev tau raug rau cov neeg ua phem.
Puas yog kev tiv thaiv kev tiv thaiv?
Cov txheej txheem tiv thaiv yog tus cwj pwm tib neeg siv cais lawv tus kheej ntawm cov xwm txheej tsis zoo, kev ua, lossis kev xav. Cov tswv yim kev puas siab puas ntsws no yuav pab tau tib neeg kom nyob deb ntawm lawv tus kheej thiab kev hem lossis kev xav tsis zoo, xws li kev ua txhaum lossis kev txaj muag.
Puas yog c txawv kev tiv thaiv kev tiv thaiv?
Siv Kev Tiv Thaiv Kev Tiv Thaiv txhawm rau tiv thaiv C. txawv ntawm kev kis mus rau lwm tus neeg mob. Kev Tiv Thaiv Kev Tiv Thaiv txhais tau tias: o Thaum twg ua tau, cov neeg mob C. C. diff yog dab tsi? Muab cov neeg mob uas muaj Clostridioides difficile kab mob nyob rau hauv ib chav ntiav thaum twg los tau.
