Zoo ib yam tuaj yeem nug, hom B hlwb yog dab tsi?

Cov ntshav no hlwb muab nce mus B - hlwb dhau ntawm cov kauj ruam. Tom qab lawv loj tuaj lawm, B - hlwb muaj nyob hauv koj cov ntshav thiab qee qhov ntawm koj lub cev xws li hauv koj cov qog ntshav. Muaj ob lub ntsiab hom ntawm cov lymphocytes : Tsi- hlwb , thiab B - hlwb.

Yuav ua li cas B cells thiaj li mob qog noj ntshav?

B hlwb tuaj yeem tiv thaiv kev txhim kho qog los ntawm kev tsim cov qog nqaij hlav-reactive antibodies, txhawb kev tua qog los ntawm NK hlwb , phagocytosis los ntawm macrophages, thiab pib ntawm CD4+ thiab CD8+ T. hlwb .
