The tight junctions (TJs) are key players in the control of blood-brain barrier (BBB) properties, the most complex TJs in the vascular system being found in the endothelial cells of brain capillaries. One of the main TJs proteins is occludin, which anchors plasma membranes of neighbour cells and is present in large amounts in the brain endothelia. Previous(More)
Claudins (Cls) are a multigene family of transmembrane proteins with different tissue distribution, which have an essential role in the formation and sealing capacity of tight junctions (TJs). At the level of the blood-brain barrier (BBB), TJs are the main molecular structures which separate the neuronal milieu from the circulatory space, by a restriction(More)
It was demonstrated that comparison of the autofluorescence spectra induced with laser radiation in ultraviolet and visible allows the identification of brain tumor tissues and normal tissues as well as the difference between them. The measurements were performed on homogenates to ensure an optimal reproducibility of the results. We conclude that the(More)
We have reported earlier that tight-junction proteins are detectable by standard immunohistochemistry in the brain parenchyma, namely in the cell bodies of neurons, astrocytes, and oligodendrocytes. Here we show, by projection to latent structures - discriminate analysis (PLS-DA), that the immunohistochemical detection profile of tight junction proteins(More)
INTRODUCTION Multiple drug resistance requires a flexible approach to find medicines able to overcome it. One method could be the exposure of existing medicines to UV laser beams to generate active photoproducts against bacteria and/or malignant tumors. METHODS The interaction of Chlorpromazine (CPZ) (irradiated with 266 nm pulsed laser beams) was studied(More)
