T pab hom 1 (Th1) cov cell yog caj ces ntawm CD4 + effector T cell uas txhawb nqa cov tshuaj tiv thaiv kab mob hauv lub cev thiab xav tau rau kev tiv thaiv tus tswv tiv thaiv kab mob vais lav thiab kab mob. Th1 cells tso tawm IFN-gamma , IB -2 , IL-10, thiab TNF-alpha/beta.
Ib yam li ib tus tuaj yeem nug, ua li cas th2 hlwb zais?
T pab hom 2 ( Th2 ) cell yog qhov sib txawv ntawm CD4+ Effector T. ntawm tes tias zais IL-4, IL-5, IL-9, IL-13, thiab IL-17E/IL-25. Cov no cell yog yuav tsum muaj kev tiv thaiv kev lim hiam thiab ua lub luag haujlwm tseem ceeb hauv kev sib koom tes tiv thaiv kev tiv thaiv kab mob rau cov kab mob loj sab nraud.
Zoo sib xws, th1 sawv rau dab tsi? Hom 1 T pab ( Th1 ) cov cell tsim cov tshuaj interferon-gamma, interleukin (IL) -2, thiab qog necrosis factor (TNF) -beta, uas qhib macrophages thiab muaj lub luag haujlwm rau kev tiv thaiv kab mob ntawm tes thiab phagocyte-tiv thaiv cov lus teb.
Ib sab saum toj no, th1 cell qhib li cas?
Th2 pab hlwb ua rau muaj kev tiv thaiv tsis txaus ntseeg, feem ntau tiv thaiv kab mob sab nrauv suav nrog helminths. Lawv tau ua los ntawm polarizing cytokines IL-4 thiab IL-2, thiab lawv cov nyhuv cytokines yog IL-4, IL-5, IL-9, IL-10, IL-13 thiab IL-25.
Puas yog cd4 th1 lossis th2?
Tus Th1 subset ntawm CD4+ NPE T cells zais cov cytokines feem ntau cuam tshuam nrog kev mob, xws li IFN-gamma thiab TNF thiab ua rau muaj kev tiv thaiv kab mob tiv thaiv kab mob ntawm tes. Th2 ua cov khoom tsim tawm cytokines xws li IL-4 thiab IL-5 uas pab B cov cell kom nthuav dav thiab sib txawv thiab cuam tshuam nrog kev tso dag tsis zoo.

Abdominal ultrasound: Ultrasound tsim cov duab ntawm lub zais zis thiab cov kua tsib ducts. Nws qhia pom cov tsos mob ntawm tus kab mob los yog qhia tias muaj qhov txhaws ntawm cov kua tsib ntws. Ultrasound yog qhov kev kuaj pom feem ntau ua los ntsuas qhov txawv txav ntawm lub zais zis

Dab tsi yog cov enzymes ua rau lub zais zis zais?
Bile yog lub zog enzyme uas pab txhawm rau zom cov rog. Thaum cov zaub mov koj noj muaj roj, lub plab thiab duodenum zais ib yam khoom uas txhawb lub zais zis kom sib cog lus, yog li ua rau cov kua tsib nkag mus rau hauv txoj hnyuv. Bile emulsifies cov rog, ua rau nws muaj zog rau kev tsim khoom
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
