The immunological properties of cerebral microvascular endothelium were directly compared with those of an extra-cerebral endothelium in vitro. Lymphocyte adhesion to cerebral endothelium is normally low, but is sensitive to induction by interferon-gamma (IFN gamma) and tumour necrosis factor-alpha (TNF alpha). Conversely adhesion to aortic endothelium is(More)
We report on a series of experiments which examines the factors controlling lymphocyte adhesion to brain endothelium in vitro and the factors which control cell migration across the endothelium, using a new migration assay. Although lymphocyte adhesion preceded migration across the brain endothelium, the two processes are not identical. We noted that(More)
Vascular endothelial cells are associated with a number of anionic molecules. These anions are important in endothelial function, particularly in regulating permeability, haemostasis and cellular traffic. To explore the nature and distribution of anions on the brain endothelial cell (BEC) surface, we have examined rat brain endothelium in culture, and in(More)
Lymphocyte adhesion to CNS endothelium is low by comparison with non-CNS endothelium. It has been proposed that this could be due to the high surface charge of brain endothelium, or a low constitutive expression of adhesion molecules. In this study we compared the influence of these factors on lymphocyte adhesion to BEC and aortic endothelium (AEC) in(More)
The purpose of the study was to investigate social tagging practice in science book context. In addition, it identified the usefulness of social tags as supplementary of controlled vocabulary to enhance the use of library resources. More specifically, this study examined to know to what extent the social tags match with controlled vocabulary, and whether or(More)
