Binding these proteins enables the formation of complexes that are, in turn, connected with actin filaments (in the case of zonula adherens junctions) or with keratin filaments (in the case of macula adherens junctions).
Accordingly, the present study was designed to explore effect of Tan IIA on BBB and cerebral edema after experimental stoke, furthermore, we studied Tan's influence on expression of the expression of intercellular adhesion molecule-1 (ICAM-1), matrix metalloproteinase-9 (MMP-9), the degradation of tight junction proteins zonula occludens-1 (ZO-1) and Occludin to further understand its protective mechanism.
RESULTS: Oral administration of coplanar PCB126, mono-ortho-substituted PCB118, and non-coplanar PCB153 (each at 150 [micro]mol/kg body weight) differentially altered expression of the TJ proteins claudin-5, occludin, and zonula occludens-1 in brain capillaries.
