3] Vim li cas cov desmosomes txuas cov keratinocytes tseem ceeb? daim tawv nqaij raug puas tsuaj ntau thiab lub cev trama. Cov desmosomes, uas txuas cov junctions, pab tuav lub hlwb ua ke thaum muaj kev ntxhov siab.
YDo desmosomes txuas keratinocytes?
Kev ywj pheej ntawm lub cev cheeb tsam, desmosomes yog qhov tseem ceeb ntawm kev sib tshuam hauv suprabasal keratinocytes[89, 90]. Hais txog desmosomal transmembrane thiab linker proteins, kev qhia ntawm desmocolin 1, desmocollin 1, thiab plakophilin 1 tshwm sim nyob rau hauv ib tug gradient.
Dab tsi ua lub luag haujlwm hauv daim tawv nqaij?
Desmosomes yog intercellular junctions uas nruab nrab cell-cell adhesion thiab thauj tog rau nkoj nruab nrab filament network mus rau plasma membrane, muab txhua yam resilience rau cov ntaub so ntswg xws li epidermis thiab lub plawv.
Dab tsi yog qhov ua haujlwm ntawm desmosomes?
Desmosomes yog tshwj xeeb thiab tau txiav txim siab ntawm daim nyias nyias uas nruab nrab ntawm tes-cell sib cuag thiab muaj zog adhesion. Adhesive kev sib cuam tshuam ntawm desmosome yog txuas mus rau qhov nruab nrab filament cytoskeleton.
desmosomes junctions pom nyob rau hauv lub cev nyob qhov twg?
Desmosomes yog ib yam ntawm cov cell-rau-cell adhesion muaj zog thiab muaj nyob rau hauv cov ntaub so ntswg uas muaj kev ntxhov siab txhua yam, xws li cov nqaij mos, zais zis, plab hnyuv.mucosa, thiab epithelia.
