Qhov sib txawv tseem ceeb ntawm monocyte thiab macrophage yog tias monocyte yog hom qe ntshav dawb loj tshaj plaws uas tuaj yeem sib txawv rau hauv macrophages lossis dendritic cells thaum macrophage yog cov qe ntshav dawb tshwj xeeb loj uas ua rau cov kab mob sib kis thiab ntxuav cov khib nyiab micro.
Lub cev tiv thaiv kab mob muaj ntau hom hlwb xws li lymphocytes, macrophages, monocytes, neutrophils, thiab lwm cov hlwb xws li basophils, eosinophils, thiab cov cell killer ntuj. Macrophages thiab monocytes yog cov qe ntshav dawb loj nrog cov duab tsis zoo; lawv txhawb kev tsim cov tshuaj tiv thaiv hauv lub cev. Ob hom cell no yog agranulocytes vim tsis muaj cytoplasmic granules. Ob hom hlwb no muaj lub luag haujlwm zoo sib xws hauv lub cev tiv thaiv kab mob xws li phagocytosis, nthuav tawm cov tshuaj tiv thaiv rau T lymphocytes, thiab tsim cov cytokine uas pab pib thiab tswj lub cev tiv thaiv kab mob.
Monocyte yog dab tsi?
Monocytes yog cov qe ntshav dawb tsis zoo uas nyob hauv cov hlab ntsha. Tsis zoo li lwm cov qe ntshav dawb, monocytes loj thiab muaj cov noob taum zoo li lub hauv paus. Thaum monocytes nkag mus rau hauv lub cev lossis cov ntaub so ntswg los ntawm cov hlab ntsha, lawv sib txawv rau hauv cov hlwb hu ua 'macrophages'; Yog li monocytes yog cov hlwb ua ntej ntawm macrophages.
Daim duab 01: Monocyte
Kwv yees li 3 - 8% ntawm cov qe ntshav dawb yog monocytes hauv tib neeg lub cev. Tag nrho cov qe ntshav dawb yog muab los ntawm cov hlwb progenitor. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv no, progenitor hlwb sib txawv rau hauv monoblast thiab ces mus rau hauv promonocytes. Promonocytes thaum kawg sib txawv rau hauv monocytes. Peb lub luag haujlwm tseem ceeb ntawm monocytes yog phagocytosis, nthuav tawm antigens, thiab tsim cov cytokines.
Macrophage yog dab tsi?
Thaum monocytes ncav cuag lub cev lossis cov ntaub so ntswg los ntawm cov hlab ntsha, lawv yuav sib txawv rau hauv macrophages. Macrophages yog cov loj, tsis sib xws, agranulated hlwb nrog lub noob taum loj. Lawv muaj peev xwm ntawm engulfing txawv teb chaws hais, uas yuav ua rau muaj kev hem thawj rau tib neeg noj qab haus huv los yog ua rau cov kab mob rau tib neeg. Peb hu qhov no engulfing txheej txheem phagocytosis. Thaum lawv engulf txawv teb chaws hais, lawv tsim ib tug membrane-bounded phagosome nyob ib ncig ntawm lawv. Tom qab ntawd cov lysosomes tso tawm lawv cov enzymes txhawm rau tua, thiab zom cov khoom siv. Tsis tas li ntawd, sai sai ua oxygen-muaj dawb radicals nyob rau hauv phagosomes kuj pab kom degrade cov kab mob.
Daim duab 02: Macrophage
Macrophages muaj peev xwm ua rau cov kab mob, kab mob, cov khib nyiab ntawm tes, thiab cov plua plav hauv lub ntsws. Thaum muaj kab mob tshwm sim hauv cov ntaub so ntswg los yog lub cev, monocytes nyob rau hauv cov hlab ntsha nyem los ntawm lub epithelium hlwb thiab nkag mus rau qhov chaw ntawm tus kab mob. Ntawm qhov chaw ntawm tus kab mob, cov monocytes sib txawv rau hauv active, phagocytic macrophages.
Dab tsi yog qhov zoo sib xws ntawm Monocyte thiab Macrophage?
- Ob leeg monocyte thiab macrophage yog cov qe ntshav dawb nrog rau lub cev tiv thaiv kab mob.
- Lawv yog agranulocytes.
- Ntxiv mus, lawv yog phagocytes.
- Lawv irregular in shape.
- Ob leeg muaj peev xwm nthuav tawm cov tshuaj tiv thaiv.
- Tsis tas li ntawd, lawv tsim cytokines.
Qhov txawv ntawm Monocyte thiab Macrophage yog dab tsi?
Monocytes thiab macrophages yog ob hom qe ntshav dawb. Monocytes yog hom loj tshaj plaws ntawm cov qe ntshav dawb uas muaj peev xwm sib txawv rau hauv macrophages thiab dendritic hlwb. Ntawm qhov tod tes, macrophages yog cov hlwb tshwj xeeb uas koom nrog hauv kev tiv thaiv hauv lub cev los ntawm kev cuam tshuam cov kab mob sib kis. Qhov no yog qhov sib txawv tseem ceeb ntawm monocyte thiab macrophage. Lwm qhov sib txawv ntawm monocyte thiab macrophage yog lawv qhov loj me; monocyte loj dua macrophage. Tsis tas li ntawd, monocytes muaj nyob rau hauv cov hlab ntsha, thaum macrophages muaj nyob rau hauv cov kua dej extracellular uas da dej cov ntaub so ntswg. Yog li, qhov no kuj yog qhov sib txawv ntawm monocyte thiab macrophage.
Summary – Monocyte vs Macrophage
Monocytes thiab macrophages yog ob hom qe ntshav dawb hauv cov ntshav. Qhov tseeb, monocytes yog cov hlwb ua ntej ntawm macrophages. Monocytes tsiv mus rau hauv cov ntaub so ntswg thiab sib txawv rau hauv macrophages. Tsis tas li ntawd, monocytes tuaj yeem sib txawv rau hauv cov hlwb dendritic ib yam nkaus. Txawm li cas los xij, macrophages yog cov hlwb tshwj xeeb hauv kev tiv thaiv kab mob hauv lub cev. Lawv nqus cov kab mob, kab mob, thiab lwm yam thiab tshem tawm cov khib nyiab ntawm peb lub cev. Macrophages yog me me. Yog li, qhov no yog qhov txawv ntawm monocyte thiab macrophage.
