Teb thiab Piav Qhia: Epidermal dendritic cells pab tiv thaiv kab mob thiab lawv kuj tsim cov xim rau ntawm daim tawv nqaij. Epidermal dendritic hlwb hu ua antigen-presenting
Thiaj li, dab tsi yog qhov ua haujlwm ntawm cov cell dendritic epidermal?
Epidermal dendritic hlwb pab qhib lub cev tiv thaiv kab mob hauv lub cev. Spiky hemispheres uas ua ke nrog kev hnov qab ntawm lub paj hlwb kawg ua rau lub ntsej muag kov tau.
Qhov thib ob, lub hom phiaj tseem ceeb ntawm cov kab mob dendritic epidermal xws li Langerhans cells) yog dab tsi? Zoo li lwm yam dendritic hlwb lawv tshwj xeeb hauv kev ua thiab nthuav qhia antigens rau T lymphocytes. Epidermal Langerhans hlwb tshwj xeeb yog ua tau zoo hauv kev ua cov kab mob antigens.
Tsis tas li lo lus nug yog, qhov twg yog cov hlwb epidermal dendritic nyob?
Langerhans hlwb (LC) yog cov tswv cuab ntawm dendritic hlwb tsev neeg, nyob hauv cov txheej hauv paus thiab suprabasal ntawm daim tawv nqaij Thiab nyob rau hauv lub epithelium ntawm lub pa, digestive thiab urogenital ib ntsuj av. Lawv tshwj xeeb hauv kev nthuav qhia antigen thiab koom nrog cov tawv nqaij tiv thaiv kab mob (SIS).
Cov kab mob epidermal dendritic cuam tshuam nrog kev ua haujlwm tsis muaj zog li cas?
Tsis ntev tom qab kis mob, tus tiv thaiv kab mob yoog raws lus teb yog ntxias los ntawm dendritic hlwb (Langerhans hlwb ) muaj nyob rau hauv daim tawv nqaij ; lawv yog lub luag haujlwm rau kev ntes, ua, thiab nthuav qhia antigens rau T lymphocytes hauv cov qog nqaij hlav hauv zos.

Neuroglial cells yog dab tsi thiab lawv lub luag haujlwm yog dab tsi?
Cov hlwb uas tsim myelin, tiv thaiv, txhawb nqa, thiab tswj kev sib npaug hauv koj lub paj hlwb hu ua glial cells. Lawv kuj tseem raug hu ua neuroglia thiab txawm tias yooj yim dua glia. Hauv cov lus ntxaws ntxaws, neuroglia yog cov hlwb hauv koj lub paj hlwb uas tsis yog neurons
Dab tsi yog qhov ua haujlwm ntawm tus txha nqaj dendritic?
Ib tug dendritic spine (los yog qaum) yog membranous protrusion los ntawm ib tug neuron's dendrite uas feem ntau tau txais tswv yim los ntawm ib tug axon ntawm lub synapse. Dendritic spines ua qhov chaw cia rau lub zog synaptic thiab pab xa hluav taws xob cov cim rau lub hlwb ntawm lub cev
Qhov sib txawv ntawm tus pab T cells thiab cytotoxic T cells yog dab tsi?
T hlwb yog li ntawd hu ua vim lawv feem ntau tsim nyob rau hauv lub thymus. Raws li cov npe hais tias pab T hlwb 'pab' lwm lub hlwb ntawm lub cev tiv thaiv kab mob, thaum cytotoxic T hlwb tua cov kab mob kis kab mob thiab qog. Tsis zoo li cov tshuaj tiv thaiv kab mob, TCR tsis tuaj yeem khi cov tshuaj tiv thaiv ncaj qha
Lub luag haujlwm ntawm T cells thiab B cells yog dab tsi?
T cells koom nrog hauv kev tiv thaiv kab mob ntawm tes, qhov B hlwb feem ntau yog lub luag haujlwm rau kev tiv thaiv kev dag ntxias (hais txog cov tshuaj tiv thaiv). Kev ua haujlwm ntawm T hlwb thiab B hlwb yog kom paub txog cov 'tsis yog tus kheej' antigens, thaum lub sijhawm ua haujlwm hu ua antigen nthuav qhia
Dab tsi yog ependymal cells thiab lawv ua dab tsi?
Ependymal Cell. Ependymal cells yog ib hom tshwj xeeb ntawm cov epithelial cells uas ua kab ke ntawm lub paj hlwb ntawm lub paj hlwb thiab ua lub luag haujlwm tseem ceeb hauv kev tsim cov kua dej hauv lub paj hlwb
