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.
Dendritic hlwb nyob qhov twg ntau tshaj?
Dendritic cells (DCs), ua ke nrog monocytes thiab macrophages, suav nrog cov kab ke mononuclear phagocyte. DCs yog cov kws tshaj lij antigen-presenting cells. Lawv muaj ntau heev ntawm lub cev thiab hauv cov ntaub so ntswg, qhov chaw lawv nkag siab thiab ua piv txwv ib puag ncig rau tus kheej-thiab tsis-tus kheej-antigens.
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.
Puas yog cov hlwb dendritic pom feem ntau hauv cov qog ntshav?
Lawv tam sim no yog cov hlwb 'tsis paub qab hau' hauv cov ntaub so ntswg, tshwj xeeb yog cov ntaub so ntswg uas raug rau sab nraud, suav nrog daim tawv nqaij, ntsws thiab txoj hnyuv. Lawv kuj muaj nyob rau hauv cov ntaub so ntswg lymphoid, suav nrog cov qog ntshav thiab spleen.
Dendritic cells ua haujlwm li cas?
Dendritic cells (DCs) sawv cev rau tsev neeg heterogeneous ntawm lub cev tiv thaiv kab mob uas txuas rau hauv lub cev thiab kev tiv thaiv kab mob. Lub luag haujlwm tseem ceeb ntawm cov hlwb innate no yog txhawm rau ntes, txheej txheem, thiab tam sim no antigens rau hloov lub cev tiv thaiv kab mob thiab kho lawv cov polarization rau hauv cov cell effector(1).
