<prompt> Yini eyenza la mangqamuzana e-T asizayo asebenze? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Ingqamuzana le-B likwazi ukubona amagciwane lapho amasosha omzimba angaphezulu alo ebopha i-antigen ethile yangaphandle. Le antigenantibody complex ithathwa yi-B cell bese icutshungulwa nge-proteolysis ibe ama-peptide. Khona-ke ingqamuzana le-B libonisa la ma-peptide e-antigenic ebusweni balo ama-molecule e-MHC ekilasini II. Le nhlanganisela ye-MHC ne-antigen iheha i-helper T cell ehambisanayo, ekhipha ama-lymphokine futhi isebenze i-B cell. Lapho ingqamuzana le-B eseliqalile ukuhlukaniswa, inzalo yalo amangqamuzana e-plasma ikhipha izigidi zamakhophi omzimba omelana nalesi simiso. La ma-antibody ajikeleza e-plasma yegazi kanye ne-lymph, abopha ama-pathogen akhombisa i-antigen futhi awaphawule ukuze abhujiswe ngokusebenza kwe-complement noma ukuze athathwe futhi abhujiswe ama-phagocyte. Ama-antibody angazivimbela ngokuqondile izinselele, ngokubopha ubuthi bama-bacterium noma ngokuphazamisa ama-receptor asetshenziswa amagciwane namagciwane ukuze athelele amangqamuzana.
