Naive T lymphocytes tau txaiscov lus teb ntau zuj zus ntxiv thaum nkag mus rau hauv lymphopenic hosts, hu ua "homeostatic proliferation" thiab "spontaneous proliferation." Kev loj hlob sai sai yog cov txheej txheem tshwj xeeb los ntawm kev tiv thaiv kab mob tsim cov hlwb phenotype nrog nce T cell …

T cell proliferation tshwm sim nyob qhov twg?

T hlwb yog tsim nyob rau hauv the Thymus thiab tau programmed kom tshwj xeeb rau ib qho txawv teb chaws particle (antigen). Thaum lawv tawm ntawm cov thymus, lawv ncig thoob plaws lub cev kom txog thaum lawv paub txog lawv cov antigen nyob rau saum npoo ntawm antigen nthuav tawm cov hlwb (APCs).

Nws yuav siv sijhawm ntev npaum li cas rau T cells kom loj hlob?

Yog ntsuas CD107a qhia, koj yuav pom cov lus teb hauv 6 teev. Yog saib T cell proliferation raws li kev ntsuas ntawm kev ua kom, nws yuav siv sij hawm 5-6 hnub.

T cell proliferation ua dab tsi?

T cell proliferation ua rau tsim ntau lab ntawm T hlwb qhia tshwj xeeb cell membrane TCRs, muaj peev xwm los khi ntau hom antigens, suav nrog tus kheej-antigens.

Pob effector T cells proliferate?

Thaum muaj kev tiv thaiv kab mob, antigen-specific lymphocytes proliferate ntau zaus los tsim ib lub pas dej loj ntawm cov hlwb. Kev nthuav dav T cell yuav tsum tau ua tib zoo tswj xyuas kom muaj txiaj ntsig zoo rau kev kis kab mob thaum zam kev tiv thaiv kab mob.
