Qhov sib txawv tseem ceeb ntawm neutrophils thiab macrophages yog cov neutrophils tsis yog antigen nthuav tawm cov hlwb thaum macrophages yog cov tshuaj tiv thaiv kab mob.
Neutrophils thiab macrophages yog leucocytes uas muaj nyob rau hauv lub cev tiv thaiv kab mob, thiab lawv ua raws li thawj thawj tiv thaiv kab mob. Cov hlwb tshwj xeeb no tuaj yeem nyem los ntawm qhov me me ntawm cov hlab ntsha thaum lub sijhawm txheej txheem hu ua diapedesis, uas thaum kawg ua rau lawv mus rau thaj chaw kis tau yooj yim. Feem ntau, cov tshuaj tiv thaiv inflammatory tshwm sim thaum cov ntaub so ntswg puas. Qhov no yog vim cov tshuaj lom neeg tso tawm los ntawm cov kab mob mus rau hauv cov ntaub so ntswg thiab cov ntshav. Cov tshuaj no thaum kawg ua rau kev nyiam ntawm neutrophils thiab macrophages ntawm cov tshuaj lom neeg los ntawm chemotaxis. Yog li, qhov no yog thawj qhov tseem ceeb ntawm kev tiv thaiv kev tiv thaiv tiv thaiv kab mob. Ntxiv mus, ob hom cell tuaj yeem phagocytize cov kab mob hauv thaj chaw muaj kab mob.
Neutrophils yog dab tsi?
Neutrophils yog hom qe ntshav dawb ntau tshaj plaws hauv cov ntshav. Neutrophils kuj yog hom granulocytes ntau tshaj. Lawv ua raws li thawj kab ntawm kev tiv thaiv thaum muaj cov tshuaj tiv thaiv kab mob lossis kis kab mob.
Daim duab 01: Neutrophil
Tsis tas li ntawd, lawv yog cov sib txawv ntawm cov hlwb uas muaj ntau ntau ntawm cov enzymes proteolytic thiab cov pa oxygen reactive uas ua rau cov ntaub so ntswg puas hauv zos thaum tso tawm rau hauv cov kab mob extracellular. Nws yuav siv li 14 hnub los tsim cov neutrophil hauv cov pob txha pob txha. Tom qab ntawd, lawv pib ncig hauv cov hlab ntsha rau 6 mus rau 14 teev. Ze li 50% ntawm cov neutrophils circulating adheres rau vascular endothelium. Cov neutrophils no tuaj yeem muaj sia nyob rau lwm 48 teev, tsis zoo li lwm cov neutrophil hlwb uas tsis txuas rau vascular endothelium.
Macrophages yog dab tsi?
Macrophages yog amoeba zoo li loj, cov hlwb tshwj xeeb uas paub txog, nkag mus thiab rhuav tshem cov neeg tawm tsam txawv teb chaws. Lawv nrov li cov neeg noj zaub mov loj. Tsis tas li ntawd, lawv ntxuav peb lub cev los ntawm engulfing microscopic khib nyiab. Lawv yog cov laus tshaj cov neeg nruab nrab ntawm lub innate system. Ntxiv mus, lawv pib los ntawm monocytes nyob rau hauv cov pob txha pob txha. Monocytes sib txawv rau hauv macrophages thaum lawv tawm thiab tsiv mus rau ntau yam ntaub so ntswg. Txij li thaum lawv loj hlob hauv cov ntaub so ntswg, peb hu lawv cov ntaub so ntswg macrophages. Cov ntaub so ntswg macrophages tuaj yeem nyob tau ntau lub hlis mus rau xyoo kom txog thaum lawv xav tau thiab rhuav tshem thaum ua lawv txoj haujlwm tiv thaiv. Cov ntaub so ntswg macrophages yog ib qho tseem ceeb heev vim lawv ua raws li cov txiaj ntsig tseem ceeb hauv kev tiv thaiv kab mob hauv lub cev.
Daim duab 2: Macrophage
Macrophages siv cov txheej txheem hu ua phagocytosis los rhuav tshem thiab tshem tawm cov khoom tsis xav tau tawm ntawm lub cev. Phagocytosis pib nrog tsim ib lub hnab tsho zoo li tus qauv hu ua phagosome vim yog cov khoom sib txuas. Tom qab ntawd, siv cov enzymes tso tawm los ntawm lysozymes, lawv zom cov khoom hauv phagosomes.
Dab tsi yog qhov zoo sib xws ntawm Neutrophils thiab Macrophages?
- Ob leeg neutrophils thiab macrophages yog cov qe ntshav dawb.
- Kuj, ob leeg yog phagocytes.
- Thiab, ob leeg ua haujlwm tiv thaiv kab mob.
- Dhau li ntawd, lawv pib ntawm pob txha pob txha.
Qhov txawv ntawm Neutrophils thiab Macrophages yog dab tsi?
Qhov sib txawv tseem ceeb ntawm neutrophils thiab macrophages yog lub peev xwm nthuav tawm cov tshuaj tiv thaiv. Tsis zoo li neutrophils, macrophages tuaj yeem nthuav tawm cov kab mob antigenic rau T lymphocytes hauv cov ntsiab lus ntawm MHC (Major Histocompatibility Complex) chav kawm II molecules tom qab engulfing cov kab mob hlwb. Tsis tas li ntawd, macrophages tuaj yeem nyob ntev dua neutrophils. Yog li, qhov no yog lwm qhov sib txawv ntawm neutrophils thiab macrophages.
Tsis tas li, ib qho sib txawv ntxiv ntawm neutrophils thiab macrophages yog lawv qhov loj me; macrophages loj dua cov neutrophils. Txij li thaum macrophages loj dua neutrophils, lawv tuaj yeem phagocyte ntau tus kab mob invader ntau dua neutrophils. Tom qab kis tau tus kab mob, neutrophils yeej tus kab mob thaum ntxov thaum macrophages dominate cov kab mob tom qab theem (1 mus rau 2 hnub tom qab kis kab mob). Yog li, qhov no kuj yog qhov sib txawv ntawm neutrophils thiab macrophages.
Tsis tas li ntawd, lwm qhov sib txawv ntawm neutrophils thiab macrophages yog cov neutrophils muaj ntau lub lobed nucleus thaum lub nucleus ntawm macrophage loj thiab puag ncig. Cov hauv qab no infographic ntawm qhov sib txawv ntawm neutrophils thiab macrophages muab cov ntsiab lus ntxiv ntawm qhov sib piv sib txawv.
Summary – Neutrophils vs Macrophages
Ntshav muaj ntau hom ntshav. Cov qe ntshav dawb yog hom loj ntawm lawv. Muaj ntau hom qe ntshav dawb (leukocytes) xws li monocytes, lymphocytes, neutrophils, eosinophils, basophils, thiab macrophages. Neutrophils thiab macrophages yog ob hom qe ntshav dawb uas ua haujlwm tiv thaiv tus kab mob. Thaum neutrophils yog cov qe ntshav dawb ntau tshaj plaws, macrophages yog cov hlwb tshwj xeeb loj uas paub tias yog cov neeg noj zaub mov loj. Neutrophils tsis muaj peev xwm nthuav tawm antigens thaum macrophages yog cov kws tshaj lij antigen nthuav tawm cov hlwb. Tsis tas li ntawd, thaum muaj kab mob, neutrophils tuaj thawj zaug thaum macrophages tuaj tom qab. Qhov no qhia txog qhov sib txawv ntawm neutrophils thiab macrophages.
