Qhov Tseem Ceeb Qhov txawv - Macrophages vs Dendritic Cells
Lymphocytes thiab phagocytes yog ob lub ntsiab ntawm lub cev tiv thaiv kab mob. Lub phagocyte yog ib hom ntawm tes uas muaj peev xwm ntawm engulfing thiab nqus cov kab mob, lwm yam txawv teb chaws hlwb, thiab kis kab mob. Muaj ob hom phagocytes: cov kws tshaj lij lossis tsis yog tus kws tshaj lij phagocytes. Cov kws tshaj lij phagocytes yog neutrophils, monocytes, macrophages, dendritic cells, thiab mast cells. Lub macrophage yog ib hom ntawm cov qe ntshav dawb uas engulfs thiab zom cov hlwb txawv teb chaws, cov khoom siv ntawm tes tsis xav tau thiab cov khib nyiab uas yuav tsum tsis muaj nyob hauv lub cev noj qab haus huv. Lawv yog cov neeg noj zaub mov loj hauv lub cev tiv thaiv kab mob. Lub dendritic cell yog ib hom antigen uas nthuav tawm cov qe ntshav dawb. Lawv ua raws li cov tub txib ntawm innate thiab adaptive tiv thaiv kab mob. Qhov sib txawv tseem ceeb ntawm macrophages thiab dendritic hlwb yog lawv txoj haujlwm; Lub luag haujlwm tseem ceeb ntawm macrophages yog ntxuav cov khib nyiab thiab tshem tawm cov kab mob thaum lub luag haujlwm tseem ceeb ntawm cov hlwb dendritic yog ua cov khoom siv antigen thiab nthuav tawm ntawm lub xov tooj ntawm tes mus rau T hlwb ntawm lub cev. Dendritic hlwb paub cov kab mob thiab nthuav tawm lawv mus rau lwm lub hlwb kom tua. Macrophages tua lawv thiab tom qab ntawd nthuav tawm lawv cov peptide mus rau lwm lub hlwb kom pab ntxiv.
Macrophages yog dab tsi?
Macrophage yog ib lub cell loj phagocytic pom nyob rau hauv lub cev tiv thaiv kab mob. Lawv nyob hauv lawv daim ntawv nyob ruaj khov hauv cov ntaub so ntswg lossis ua cov qe ntshav dawb ntawm cov chaw kis kab mob. Hauv Greek, macrophages txhais tau tias "cov neeg noj zaub mov loj". Macrophages engulf thiab zom cov khib nyiab ntawm tes, cov khoom txawv teb chaws, cov kab mob, cov qog nqaij hlav cancer, thiab txhua yam uas tsis yog lub cev. Cov txheej txheem no hu ua phagocytosis. Lawv noj cov khib nyiab ntawm tes thiab cov kab mob, coj zoo li ameba. Macrophages siv cov txheej txheem phagocytosis kom tshem tawm cov khoom txawv teb chaws. Lawv engulf cov khoom txawv teb chaws los ntawm kev tsim ib lub hnab tsho zoo li cov qauv hu ua phagosome nyob ib ncig ntawm lawv. Lysosomes tso cov enzymes digestive rau phagosome. Cov enzymes no zom thiab rhuav tshem cov kab mob thiab cov khib nyiab ntawm tes. Yog li, macrophages yog cov khoom tseem ceeb ntawm lub cev tiv thaiv kab mob uas rov ua dua cov hlwb tuag thiab lwm cov khib nyiab ntawm tes. Macrophages raug suav hais tias yog cov khoom tseem ceeb hauv cov txheej txheem ntxuav tes.
Daim duab 01: Macrophage
Macrophages yog tsim los ntawm monocytes uas yog tsim los ntawm cov qia hlwb ntawm cov pob txha pob txha. Lawv ntws los ntawm cov ntshav thiab tawm hauv cov ntshav tom qab kev laus.
Dendritic Cells yog dab tsi?
Dendritic cells yog ib hom qe ntshav dawb uas nyiam ua cov tshuaj tiv thaiv kab mob. Lawv ua lub luag haujlwm tseem ceeb hauv lub cev tiv thaiv kab mob. Dendritic hlwb muaj peev xwm ua rau lub cev tiv thaiv kab mob hauv lub cev tsis muaj zog lossis so tsis muaj T lymphocytes tawm tsam cov kab mob. Lawv paub thiab ntes cov antigens ntawm lub cev invading thiab tom qab ntawd txheej txheem thiab nthuav tawm lawv ntawm lub xov tooj ntawm tes nrog rau lwm cov molecules tsim nyog. Dendritic hlwb kuj pab B hlwb ua haujlwm thiab tswj lawv lub cev tiv thaiv kab mob.
Daim duab 02: Dendritic cell hauv daim tawv nqaij
Dendritic hlwb tau pom thawj zaug los ntawm Ralph Steinman hauv xyoo 1970. Lawv pom muaj nyob rau hauv cov ntaub so ntswg uas nyob rau hauv kev sib cuag nrog rau sab nraud ib puag ncig xws li daim tawv nqaij, qhov ntswg hauv ob sab phlu, ntsws, plab, hnyuv, thiab lwm yam. Cov hlwb no muaj cov kev kwv yees hu ua dendrites. Li no lub npe tau muab ua cov hlwb dendritic.
Dab tsi yog qhov zoo sib xws ntawm Macrophages thiab Dendritic Cells?
- Macrophages thiab dendritic cells yog cov qe ntshav dawb
- Ob hom cell yog phagocytes uas engulf pathogens thiab cell debris.
Qhov txawv ntawm Macrophages thiab Dendritic Cells yog dab tsi?

Summary – Macrophages vs Dendritic Cells
Macrophages thiab dendritic hlwb yog ob hom qe ntshav dawb thiab phagocytes. Macrophages thiab dendritic hlwb sib txawv hauv morphology thiab kev ua haujlwm. Macrophages yog lub npe hu ua cov neeg noj zaub mov loj hauv lub cev tiv thaiv kab mob vim lawv yog lub cev tiv thaiv kab mob tseem ceeb uas noj cov kab mob thiab cov khib nyiab ntawm tes thiab ntxuav lub cev. Dendritic cells yog cov tshuaj tiv thaiv kab mob tiv thaiv kab mob. Qhov no yog qhov txawv ntawm macrophages thiab dendritic hlwb.
