Thaum kawg, fibroblastic reticular cells (FRCs) nthuav qhia thiab nthuav tawm cov ntaub so ntswg peripheral txwv antigen rau T cov hlwb ua ib feem ntawm peripheral tolerance mechanism, thiab lawv lub peev xwm los txhawb T hlwb yog Hloov pauv nyob ntawm qhov mob ntawm cov ntaub so ntswg (56).
Cov hlwb twg tuaj yeem ua raws li cov tshuaj tiv thaiv kab mob?
Cov hom tseem ceeb ntawm cov neeg ua haujlwm antigen-presenting cells yog dendritic cells, macrophages thiab B cells.
Cov tshuaj tiv thaiv puas tuaj yeem ua cov tshuaj tiv thaiv kab mob?
Nyob rau hauv cov tshuaj tiv thaiv kab mob thib ob, nco B hlwb lawv tus kheej tuaj yeem ua raws li cov tshuaj tiv thaiv tam sim no thiab qhib cov pab T hlwb, nrog rau ua lub hom phiaj tom ntej ntawm tus pab cuam T cells..
Yuav ua li cas rau cov tshuaj tiv thaiv kab mob tam sim no?
Ib qho tshuaj tiv thaiv kab mob tam sim no (APC) yog lub cev tiv thaiv kab mob uas ntes, engulfs, thiab qhia txog kev hloov lub cev tiv thaiv kab mob txog tus kab mob. Thaum kuaj pom tus kab mob, cov APCs no yuav phagocytose cov kab mob thiab zom nws los ua ntau qhov sib txawv ntawm cov tshuaj tiv thaiv.
Puas yog cov tshuaj tua kab mob ntuj tsim cov tshuaj tiv thaiv kab mob?
Antigen kev nthuav qhia los ntawm NK hlwb induced ib tug polyfunctional CD4 + T cell activation, zoo li zoo li uas tau pom thaum siv moDC li APCs, tus yam ntxwv los ntawm zus tau tej cov Th1 cytokines thiab tso tawm ntawm lawv cytotoxic granules, nyob rau hauv ib feem ntawm lub tshuab txais lub hlwb.

Puas yog cov tshuaj tiv thaiv kab mob sib txuas tau suav tias yog kev tiv thaiv kab mob?
Antibody drug conjugates (ADCs) yog ib hom tshuaj tiv thaiv kab mob. Lawv yog tsim los ntawm peb yam: monoclonal antibody (mAb) thiab cytotoxic payload ua los ntawm cov kws khomob kws khomob, uas txuas nrog ua ke siv cov tshuaj sib txuas . Puas yog tshuaj tiv thaiv kab mob tib yam li kev tiv thaiv kab mob?
Puas yog cov tshuaj tiv thaiv kab mob tiv thaiv kab mob ua rau lupus?
Antinuclear cov tshuaj tiv thaiv yog autoantibodies - cov tshuaj tiv thaiv kab mob uas tsom rau cov proteins ib txwm nyob hauv lub hauv paus ntawm lub cell. Qhov no dhau los ua qhov tseem ceeb hauv kev kho mob thaum ANAs teeb liab lub cevpib tsom nws tus kheej, uas tuaj yeem ua rau cov kab mob autoimmune, suav nrog lupus, Sjogren's syndrome, thiab cov kab mob sib xyaw ua ke .
Cov neeg mob tiv thaiv kab mob yuav tsum tau txais cov tshuaj tiv thaiv?
Vim li cas CDC thiaj pom zoo tias cov neeg uas muaj kev tiv thaiv kab mob tiv thaiv kab mob tau txais koob tshuaj mRNA COVID-19 ntxiv los ntxiv rau 2-dose thawj koob tshuaj tiv thaiv kab mob mRNA COVID-19? Cov neeg uas muaj kev tiv thaiv kab mob los yog cov neeg siv tshuaj tiv thaiv kab mob yog nyob ntawm muaj kev pheej hmoo ntau rau tus kab mob COVID-19 hnyav .
Ntawm kev kuaj tshuaj tiv thaiv kab mob tiv thaiv kab mob?
Kev kuaj mob hnyav yog siv los txiav txim seb cov tshuaj tua kab mob twg yuav cuam tshuam kev loj hlob ntawm cov kab mob lossis cov kab mob ua rau muaj kab mob tshwj xeebCov txiaj ntsig ntawm qhov kev sim no yuav pab tus kws kho mob txiav txim siab seb cov tshuaj twg yog yuav ua tau zoo tshaj plaws hauv kev kho tus neeg mob .
Cov tshuaj tiv thaiv kab mob puas muaj kev tiv thaiv kab mob?
Nws yuav siv sijhawm ntev npaum li cas txhawm rau txhim kho kev tiv thaiv kab mob COVID-19 tom qab tau txais cov tshuaj tiv thaiv? tshuaj tiv thaiv COVID-19 qhia peb lub cev tiv thaiv kab mob kom paub txog thiab tawm tsam tus kab mob uas ua rau COVID-19.
