Langerhans hlwb yog cov pob txha pob txha- muab tau, antigen-processing thiab -presenting cells pom feem ntau nyob rau hauv suprabasal epidermal txheej. Txawm li cas los xij, lawv tsis yog tshwj xeeb rau cov epidermis thiab pom muaj nyob rau hauv lwm cov squamous epithelia thiab nyob rau hauv ib txwm dermis.
Cov hlwb twg yog Langerhans hlwb?
Langerhans cells (LC) yog cov pejxeem tshwj xeeb ntawm cov ntaub so ntswg-nyob hauv macrophagesuas tsim lub network ntawm cov hlwb thoob plaws ntawm daim tawv nqaij, tab sis uas muaj peev xwm txav los ntawm lub epidermis rau cov kua dej ntws tawm (LN). Lawv qhov chaw nyob ntawm daim tawv nqaij barrier qhia lub luag haujlwm tseem ceeb ntawm kev tiv thaiv kab mob.
Peb lub ntsiab antigen yog dab tsi?
Lub cev tiv thaiv kab mob muaj peb hom tshuaj tiv thaiv kab mob, piv txwv li, macrophages, dendritic cells, thiab B cells.
Puas yog Langerhans cell yog dendritic cell?
Langerhans cells (LCs) yog ib pawg tshwj xeeb ntawm cov hlwb dendritic(DCs) uas tsim cov txheej txheem ntawm daim tawv nqaij.
Puas yog Langerhan hlwb dendritic hlwb lossis macrophages?
Peb qhov kev xav ntawm tus kheej thiab kev ua haujlwm ntawm Langerhans hlwb (LCs) ntawm cov epidermis tau hloov pauv ntau heev. Ib zaug xav tias yog cov neeg sawv cev ntawm cov neeg sawv cev ntawm dendritic cell (DC) kab mob, lawv tam sim no suav tias yog ib qho tshwj xeeb ntawm cov ntaub so ntswg-cov neeg nyob hauv macrophages

Puas yog tus kws kho mob hlwb puas yog tus kws kho hlwb?
Qhov kev sib piv no, txawm tias tsis zoo tag nrho, tuaj yeem pab nkag siab qhov txawv: Cov kws kho mob tsom mus rau thiab kho cov tsos mob tshwm sim hauv lub hlwb uas ua rau kev ua haujlwm tsis zoo, piv txwv li; tib neeg tus cwj pwm, thaum cov kws kho mob hlwb tsom rau thiab kho cov tsos mob tshwm sim hauv lub hlwb uas ua rau muaj qhov txawv txav tsis txaus ntseeg… Neurology puas yog kev puas siab puas ntsws?
Puas cov pov thawj tawm tsam yuav tsum tau nthuav tawm?
Ib qho kev zam rau kev nthuav tawm ib tug tim khawv ua ntej yog "tus tim khawv tsis lees paub". Tus neeg tim khawv tsis txaus siab yog tus neeg uas raug hu los ua tim khawv tsuas yog tom qab tus neeg tawm tsam tau ua pov thawj lossis nthuav qhia lawv rooj plaub.
Vim li cas cov neeg nthuav qhia siv cov kev pab nthuav qhia?
Presentation aids pab cov neeg mloog kom nkag siab ntau ntxiv txog tus neeg hais lus ua ob txoj hauv kev: lawv pab qhia meej thiab lawv pab qhia. Cov kev pab nthuav qhia tuaj yeem pab cov neeg tuaj saib kom nkag siab txog cov tswv yim nyuaj lossis cov txheej txheem thiab tseem tuaj yeem qhia tias cov tswv yim twg tseem ceeb tshaj plaws hauv kev hais lus .
Los ntawm leej twg tau nthuav tawm qhov kev faib tawm ntawm phonological tawm tsam?
Trubetzkoy tau nthuav tawm nws qhov kev faib tawm ntawm hom phonological tawm tsam hauv 1936 (1936a) . Kev tawm tsam phonological yog dab tsi? A phonological kev tawm tsam yog tau kawg tsim los ntawm cov chav sib txawv (cov yam ntxwv ntsig txog, xov tooj, archiphonemes, tonemes, architonemes) hais txog ntawm tus kheej yam lus .
Puas yog cov hlwb endocrine yog hom paj hlwb?
ua haujlwm ntawm nws tus kheej ntawm endocrine system. … Cov kab mob endocrine. A) yog hom paj hlwb . Cov hlwb twg yog cov hlwb endocrine? Muaj peb hom kab mob endocrine; alpha cells uas zais glucagon, beta hlwb uas tso cov tshuaj insulin, thiab delta hlwb uas inhibit qhov tso tawm ntawm glucagon thiab insulin:
