endothelial dysfunction is thought to be a central pathogenic feature in preeclampsia on the basis of elevated adhesion molecules. soluble forms of these molecules can be detected in plasma, and their concentrations are thought to reflect the degree of activation of a particular cell type. the aim of the present study was to compare the levels of soluble vascular cell adhesion molecule-1 (svcam...

Ectopie expression of Carcinoembryonic antigen (CEA) by the mela noma cell line Mel Wei led to alterations in cell morphology and to changes in the expression of two melanoma-associated cell adhesion mol ecules, neural cell adhesion molecule and MUC18. The normally flat, triangular cells developed neurite-like extensions and exhibited a less organized growth pattern. When compared to untransfec...

Investigations examining the role of polysialic acid (PSA) on the neural cell adhesion molecule (NCAM) in synaptic plasticity have yielded inconsistent data. Here, we addressed this issue by determining whether homosynaptic long-term potentiation (LTP) and heterosynaptic long-term depression (LTD) induce changes in the distribution of PSA-NCAM in the dentate gyrus (DG) of rats in vivo. In addit...

Impairment of GABA-mediated inhibition is one of the main hypotheses invoked to explain seizure activity, both in experimental models and in human epilepsy. We have studied the distribution and the neurochemical characteristics of certain GABAergic circuits in the normal and epileptic human sclerotic hippocampal formation. We have focused our attention mainly on chandelier cells because, togeth...

OBJECTIVE P-selectin is an adhesion molecule expressed by activated endothelial cells and platelets favouring the leukocyte adherence to microvascular endothelium. A soluble form of this molecule has been described, whose serum levels were found to be elevated and correlate with disease activity in rheumatoid arthritis (RA) patients. Aim of this study was to determine soluble P-selectin levels ...
