Hauv cov xwm txheej no, cov tiv thaiv kab mob lawv siv cell -nruab nrab kev tiv thaiv rau rhuav tshem mob lub cev hlwb . T hlwb yog lub luag haujlwm rau ntawm tes -nruab nrab kev tiv thaiv . Tua neeg T hlwb (cytotoxic cov T hlwb ) pab tshem tawm lub cev uas kis tus kab mob hlwb los ntawm kev tso cov co toxins rau hauv lawv thiab txhawb apoptosis.
Tib neeg tseem nug, hom cell twg yog lub luag haujlwm tiv thaiv kab mob hauv cov cell?
Interestingly, ntau cov kab mob intracellular vam hauv ib qho ntawm qhov ua tau zoo tshaj plaws hom xov tooj ntawm kev tiv thaiv kab mob tiv thaiv kab mob, uas yog, mononuclear phagocytes xws li macrophages thiab dendritic hlwb (DCs) [5].
Ib yam li ntawd, yuav ua li cas T cells rhuav tshem cov kab mob? Cov T hlwb thiab B. hlwb hu ua ke cov lymphocytes . Lawv ua qhov no los ntawm ncaj qha tua cov hlwb uas tau invaded los ntawm kab mob , lossis los ntawm kev tso cov tshuaj lom hu ua "cytokines," uas tuaj yeem txhawb lwm tus neeg tua neeg hlwb tshwj xeeb muaj peev xwm ua kom puas lub kab mob.
Ib yam nkaus, lub luag haujlwm ntawm T cells hauv kev tiv thaiv kab mob ntawm tes yog dab tsi?
Kev tiv thaiv ntawm tes yog kho kom haum xeeb los ntawm T lymphocytes , kuj hu ua T hlwb . Lawv lub npe hais txog lub cev uas lawv tsim tawm: thymus. Hom ntawm kev tiv thaiv txhawb nqa kev puas tsuaj ntawm cov kab mob me me nyob hauv phagocytes, lossis tua cov kab mob hlwb kom tshem tawm cov chaw tso dej ntawm kev kis kab mob.
Hom kev tiv thaiv twg ua T cells muab?
Lawv yog qhov tseem ceeb hauv kev tuav tswv tiv thaiv kab mob teb tiv thaiv kab mob. T hlwb ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kab mob hauv lub cev xws li cov kab mob, protozoa thiab kab mob intracellular, thiab hauv kev tiv thaiv rau extracellular pathogens los ntawm muab pab rau cov tshuaj tiv thaiv kab mob.
Pom zoo:
Dab tsi yog kev tiv thaiv kab mob tiv thaiv kab mob hauv microbiology?
Kev tiv thaiv kev tiv thaiv yog ob txoj hauv kev cuam tshuam nrog kev tiv thaiv tsis zoo (cov tshuaj tiv thaiv tsim los ntawm B cells) thiab kev tiv thaiv ntawm tes (T cells qhia tawm tsam cov kab mob hauv hlwb). Antigens, tseem hu ua immunogens, yog cov lwg me me uas qhib kev tiv thaiv kev tiv thaiv
Qhov twg ntawm cov tshuaj tiv thaiv hauv qab no yog siv rau kev txhaj tshuaj tiv thaiv kab mob?
Passive Immunization DISEASE NAME OF MATERIAL Cytomegalovirus Cytomegalovirus immun globulin, txhaj tshuaj tiv thaiv kab mob Diphtheria Diphtheria antitoxin, equine Rabies Rabies tiv thaiv globulin, tib neeg Measles Immune globulin, tib neeg
Agar yog dab tsi siv rau kev sim tshuaj tiv thaiv kab mob tiv thaiv kab mob?
Müeller-Hinton agar nquag siv hauv qhov tshuaj tiv thaiv kab mob tiv thaiv kab mob no
Hom cell twg hauv lub cev tiv thaiv kab mob tsim cov tshuaj tiv thaiv?
Lymphocytes yog ib hom tseem ceeb ntawm lub cev tiv thaiv kab mob. Lymphocytes feem ntau muab faib ua B thiab T hlwb. B lymphocytes tsim cov tshuaj tiv thaiv - cov protein (gamma globulins) uas lees paub cov tshuaj txawv teb chaws (antigen) thiab muab lawv tus kheej rau lawv
Vim li cas cov hlwb hauv MM Tumors raug rhuav tshem los ntawm kev tiv thaiv kab mob?
MM yog tshwm sim los ntawm qhov ua tsis tau zoo ntawm cov protein nyob hauv cov cell ntawm daim nyias nyias. Cov cell hauv MM qog tuaj yeem raug rhuav tshem los ntawm kev tiv thaiv kab mob
