Sphingosine 1-phosphate receptor 1 (S1P(1)) is critical for lymphocyte recirculation and is a clinical target for treatment of multiple sclerosis. By generating a short-duration S1P(1) agonist and mice in which fluorescently tagged S1P(1) replaces wild-type receptor, we elucidate physiological and agonist-perturbed changes in expression of S1P(1) at a subcellular level in vivo. We demonstrate d...
If we assume with Heidenhain and others, as most physiologists now do, that urine is produced by a 'vital' activity of the cells of the glomeruli and of the convoluted tubules, we may perhaps express our findings by the statement that morphin increases the 'physiological permeability' of the kidney cells while it decreases the same kind of permeability of the endothelia of the capillaries of ot...
An in vitro model is described for studying the interaction between lymphocytes and high-endothelial venules (HEV) of lymph nodes. Rat or mouse lymphocytes which were layered over fixed sections of syngeneic lymph nodes adhered selectively to the endothelium of HEV but did not bind to other vascular endothelia. Evidence is presented that adherence to HEV in vitro is a property of recirculating ...
Primary CNS lymphoma is an aggressive form of non-Hodgkin lymphoma whose growth is restricted to the central nervous system. We used cDNA microarray analysis to compare the gene expression signature of primary CNS lymphomas with nodal large B-cell lymphomas. Here we show that while individual cases of primary CNS lymphomas may be classified as germinal center B-cell, activated B-cell, or type 3...
It has been speculated that beta-chemokines play a pivotal role in the development of peripheral nervous system (PNS) disorders characterized by mononuclear cell infiltration. In experimental allergic neuritis (EAN), an animal model for human Guillain-Barré syndrome (GBS) with mononuclear cell infiltration, we found by quantitative PCR that beta-chemokine messages were upregulated during the ac...
GATA-2, a transcription factor that has been shown to play important roles in multiple organ systems during embryogenesis, has been ascribed the property of regulating the expression of numerous endothelium-specific genes. However, the transcriptional regulatory hierarchy governing Gata2 activation in endothelial cells has not been fully explored. Here, we document GATA-2 endothelial expression...
