Dendritic hlwb muaj nyob rau hauv cov ntaub so ntswg uas muaj kev sib cuag nrog sab nraud ib puag ncig xws li hla ntawm daim tawv nqaij (tam sim no li Langerhans hlwb) thiab hauv ob sab phlu ntawm lub qhov ntswg, ntsws, plab thiab hnyuv. Cov ntawv tsis paub tab kuj pom muaj nyob hauv cov ntshav.
Dab tsi yog cov txheej txheem dendritic pom?
Cov hlwb no nyob hauv txheej suprabasal ntawm cov epidermis, thiab muaj cov qib siab ntawm CDla ntawm lawv cov txheej txheem dendritic, thiab muaj Birbeck granules.
DCs pom nyob qhov twg?
Dendritic cells (DCs) (saib cov lus hauv qab taw qhia) tuaj yeem pom hauv peb hom chaw nyob hauv lub cev. Lawv tam sim no yog cov hlwb 'tsis paub tab' hauv cov ntaub so ntswg peripheral, tshwj xeeb yog cov ntaub so ntswg uas raug rau sab nraud ib puag ncig, suav nrog daim tawv nqaij, ntsws thiab txoj hnyuv.
Dendritic hlwb nyob qhov twg hauv lub ntsws?
Nyob rau hauv lub ntsws noj qab haus huv, cov pejxeem loj ntawm DCs yuav pom muaj nyob rau hauv cov ntaub so ntswg es tsis yog nyob rau hauv airspaces. CD103+ DCs muaj ntau yam cuam tshuam nrog pulmonary epithelium, thaum qhov chaw ntawm CD11b+ DCs yog feem ntau nyob rau hauv cov ntaub so ntswg.[125, 126].
cov hlwb dendritic nyob qhov twg?
Dendritic hlwb feem ntau pom muaj nyob rau hauv tissue uas muaj kev sib cuag nrog sab nraud ib puag ncig xws li daim tawv nqaij thiab hauv ob sab phlu ntawm lub qhov ntswg, ntsws, plab thiab hnyuv. Cov hlwb kuj pom nyob rau hauv cov ntshav tsis paub qab hau.

Cov meningiomas feem ntau pom nyob qhov twg?
Meningioma yog hom mob tshaj plaws ntawm lub paj hlwb thawj, suav txog kwv yees li 30 feem pua ntawm tag nrho cov qog hlwb. Cov qog no tshwm sim nyob rau hauv meninges, uas yog peb txheej txheej ntawm cov ntaub so ntswg ntawm pob txha taub hau thiab lub hlwb uas npog thiab tiv thaiv lub hlwb nyob rau hauv lub pob txha taub hau .
Pom cov hlwb dendritic nyob qhov twg?
Dendritic hlwb muaj nyob rau hauv cov ntaub so ntswg uas muaj kev sib cuag nrog sab nraud ib puag ncig xws li hla ntawm daim tawv nqaij (tam sim no li Langerhans hlwb) thiab hauv ob sab phlu ntawm lub qhov ntswg, ntsws, plab thiab hnyuv. Cov ntawv tsis paub tab kuj pom muaj nyob hauv cov ntshav .
Qhov dej faib feem ntau pom nyob qhov twg?
Kev faib loj, saum toj no, cais cov dej ntws ntawm North America nruab nrab ntawm Pacific (sab hnub poob) thiab Arctic, Atlantic, thiab Gulf of Mexico (sab hnub tuaj) Kev faib yog qhov elevated ciam teb sib cais thaj chaw uas yog drained los ntawm txawv dej systems.
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
Feem ntau ntawm atp nyob qhov twg hauv cov hlwb prokaryotic?
ATP yog tsim nyob rau hauv plasma membranentawm cov hlwb prokaryotic. ATP yog lub ntsiab lub zog cia molecule pom nyob rau hauv hlwb . ATP tsim nyob rau hauv cov hlwb prokaryotic nyob qhov twg? Mitochondria, piv txwv li, yog cov organelles uas muab eukaryotes nrog rau feem ntau ntawm lawv lub zog los ntawm kev tsim lub zog nplua nuj molecules hu ua ATP.
