Peb hom ntawm cov lymphocytes yog T hlwb , B hlwb , thiab tus neeg tua neeg ntuj hlwb . Cov T hlwb rhuav tshem cov kab mob hauv ib qho tshwj xeeb thiab qhib B hlwb los tsim cov tshuaj tiv thaiv antigen tshwj xeeb. Phagocytes tuaj yeem yog macrophages, neutrophils, monocytes, dendritic hlwb lub mast hlwb.
Kuj paub, cov hlwb twg yog phagocytes?
Cov kws tshaj lij phagocytes suav nrog ntau hom cov qe ntshav dawb (xws li neutrophils , monocytes cov , macrophages , mast cells, thiab dendritic hlwb ).
Tsis tas li ntawd, B hlwb puas tuaj yeem ua phagocytosis? Ntau hom hlwb ntawm kev tiv thaiv kab mob ua phagocytosis , xws li neutrophils, macrophages, dendritic hlwb , thiab B cov lymphocytes . Lwm txoj haujlwm ntawm phagocytosis hauv kev tiv thaiv kab mob yog noj thiab rhuav tshem cov kab mob (zoo li kab mob thiab kab mob) thiab kis tau hlwb.
Ib sab ntawm no, puas yog lymphocytes phagocytic?
Phagocytic cov hlwb suav nrog neutrophils, eosinophils, monocytes, macrophages, dendritic cells, thiab B- cov lymphocytes . Phagocytosis yog thawj txoj hauv kev siv los ntawm lub cev tshem tawm cov kab mob dawb hauv cov ntshav thiab cov ntaub so ntswg.
Puas yog B cells qhib T cells?
Feem ntau B cev Cov lus teb rau antigen xav tau kev sib cuam tshuam ntawm B hlwb nrog T pab hlwb (thymus-dependent ua kom ). Thaum ua kom , B hlwb nthuav tawm thiab tsim cov chaw loj uas lawv sib txawv hauv kev nco B hlwb los yog ntshav hlwb.

T cells thiab B cells ua haujlwm li cas?
Tom qab ntawd koj lub cev tuaj yeem tsim cov riam phom zoo tshaj plaws tiv thaiv cov neeg tawm tsam, uas tuaj yeem yog kab mob, kab mob lossis kab mob parasites. Lwm hom T-cells paub thiab tua cov kab mob uas muaj kab mob ncaj qha. Qee qhov pab B-cells ua cov tshuaj tiv thaiv kab mob, uas nthuav dav thiab khi rau antigens. T-cell (txiv kab ntxwv) tua kab mob qog noj ntshav (mauve)
Qhov sib txawv ntawm tus pab T cells thiab cytotoxic T cells yog dab tsi?
T hlwb yog li ntawd hu ua vim lawv feem ntau tsim nyob rau hauv lub thymus. Raws li cov npe hais tias pab T hlwb 'pab' lwm lub hlwb ntawm lub cev tiv thaiv kab mob, thaum cytotoxic T hlwb tua cov kab mob kis kab mob thiab qog. Tsis zoo li cov tshuaj tiv thaiv kab mob, TCR tsis tuaj yeem khi cov tshuaj tiv thaiv ncaj qha
Lub luag haujlwm ntawm T cells thiab B cells yog dab tsi?
T cells koom nrog hauv kev tiv thaiv kab mob ntawm tes, qhov B hlwb feem ntau yog lub luag haujlwm rau kev tiv thaiv kev dag ntxias (hais txog cov tshuaj tiv thaiv). Kev ua haujlwm ntawm T hlwb thiab B hlwb yog kom paub txog cov 'tsis yog tus kheej' antigens, thaum lub sijhawm ua haujlwm hu ua antigen nthuav qhia
Puas yog lo lus dav dav txhais tau tias yog mob ntawm daim tawv nqaij lossis pob khaus uas tuaj yeem muaj ntau yam ua rau nws yog ib qho cim ntawm ntau hom tawv nqaij tsis xws luag?
Dermatitis yog lo lus dav dav uas piav txog kev ua rau tawv nqaij. Dermatitis yog ib yam mob uas muaj ntau yam ua rau thiab tshwm sim ntau yam. Nws feem ntau yog khaus, tawv nqaij qhuav los yog pob khaus ntawm daim tawv nqaij o, reddened
Dab tsi yog lo lus rau ib tus neeg muaj tshuaj lom uas ua rau muaj kev puas tsuaj lossis kev yug me nyuam hauv lub fetus lossis embryo?
Teratology. Teratogens yog cov khoom uas yuav ua rau yug me nyuam tsis xws luag los ntawm kev cuam tshuam rau embryo lossis fetus
