Endothelial hlwb hauv ob sab phlu ntawm phab ntsa yog txuas nrog adherens, tight thiab gap junctions. Cov junctional complexes muaj feem xyuam rau cov uas pom ntawm epithelial junctions tab sis nrog cov kev hloov tseem ceeb ntawm cov molecules tshwj xeeb thiab lub koom haum.
Puas yog cov hlwb endothelial nruj junctions?
Cov hlwb endothelial tau haum nrog cov qauv tshwj xeeb, xws li cell-cell adhesion complexes obliterating paracellular chaw(nruj junctions) thiab ib qho kev thauj thiab shuttle proteins tswj cov flux ntawm ions thiab solutes.
Puas cov hlwb epithelial muaj qhov sib txuas nruj?
Tight junctions tsim qhov txuas txuas txuas txuas ntxiv ntawm cov hlwb epithelial, uas yuav tsum tau cais cov ntaub so ntswg thiab tswj kev xaiv txav ntawm cov kua nplaum hla lub epithelium.
Dab tsi yog qhov sib txuas nruj hauv hlwb?
Tight junctions yog qhov chaw sib ze ntawm ob lub hlwb uas nws daim nyias nyias koom ua ke los tsim cov dej tsis zoo rau cov dej. Tight junctions ua haujlwm tseem ceeb-xws li tuav cov hlwb ua ke-thiab tsim kev tiv thaiv thiab kev ua haujlwm.
Dab tsi yog cov kab mob endothelial nruj?
Endothelial nruj junctions (TJs) tswj kev thauj cov dej, ions, thiab cov molecules los ntawm txoj kev paracellular, ua haujlwm tseem ceeb hauv cov hlab ntsha thiab tswj vascular homeostasis.
