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
