Langerhans hlwb yog dendritic hlwb nyob rau hauv daim tawv nqaij uas muaj kev tiv thaiv kab mob (Daim duab 2.4). Lawv tau muab los ntawm cov pob txha pob txha thiab tsim txog li 5% ntawm cov hlwb nyob rau hauv lub epidermis.
Cov lus nug tseem yog, Langerhans hlwb ua dab tsi?
Cov alpha hlwb ntawm cov islets ntawm Langerhans tsim cov tshuaj tiv thaiv kab mob, glucagon, uas tso cov piam thaj los ntawm daim siab thiab cov rog los ntawm cov nqaij rog. Nyob rau hauv tas li ntawd, cov piam thaj thiab cov fatty acids dawb nyiam insulin tso tawm thiab inhibit glucagon tso tawm.
Ib yam nkaus, dab tsi yog txoj haujlwm ntawm Langerhans hlwb hauv daim tawv nqaij? Langerhans hlwb populate lub epidermis los ntawm kev loj hlob thaum ntxov raws li ib tug ntom network ntawm lub cev tiv thaiv kab mob sentinels. Cov no hlwb ua raws li tus neeg saib xyuas sab nraud ntawm lub cev tiv thaiv kab mob cutaneous thiab yuav ua rau muaj kev cuam tshuam thawj zaug tawm tsam cov kab mob uas tau ntsib los ntawm tawv nqaij.
Ib yam li ntawd, nws tau nug, qhov twg cov hlwb Langerhans pib ua ntej lawv tsiv mus rau daim tawv nqaij?
ORIGIN NTAWM LANGERHANS CELLS Cov Langerhans hlwb (LCs) Cov pib los ntawm cov pob txha thiab ces tsiv teb tsaws mus rau hauv lub epithelium ua lub luag haujlwm ntawm antigen paub thiab kev nthuav qhia
Puas yog Langerhans cells cov ntshav dawb?
Langerhans ' hlwb yog cov qe ntshav dawb hauv kev tiv thaiv kab mob uas ib txwm ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv lub cev tiv thaiv kab mob, kab mob thiab lwm yam kev ua phem. Lawv muaj nyob rau hauv daim tawv nqaij, lymph nodes, spleen, pob txha pob txha thiab lub ntsws.

Qhov twg ntawm qhov muag xa cov cim rau lub hlwb?
Cov retina tom qab ntawd xa cov teeb meem paj hlwb raug xa los ntawm sab nraub qaum ntawm lub qhov muag mus rau lub paj hlwb. Cov paj hlwb optic nqa cov cim no mus rau lub hlwb, uas txhais lawv ua duab pom.

Cov hlwb twg yog cov tshuaj tiv thaiv uas nthuav tawm cov hlwb?
Antigen-presenting cells (APCs) yog ib pawg neeg tsis muaj zog tiv thaiv kab mob uas kho cov kab mob hauv lub cev los ntawm kev ua thiab nthuav tawm cov tshuaj tiv thaiv rau kev lees paub los ntawm qee cov lymphocytes xws li T hlwb. Classical APCs suav nrog dendritic cells, macrophages, Langerhans cells thiab B cells
Cov tshuaj twg uas ua rau lub hauv nruab nrab lub paj hlwb yog Schedule II cov tshuaj thiab tsis tuaj yeem rov ua dua?
Barbiturates yog cov tshuaj tau los ntawm barbituric acid thiab ua raws li sedative lossis hypnotic. Cov tshuaj yuav tau sau los ntawm tus kws kho mob, tab sis yuav tsis muab rov qab. Qee qhov piv txwv ntawm Schedule II tshuaj yog morphine, codeine, fentanyl, meperidine (Demerol), hydromorphone (Dlaudid) thiab oxycodone
