Recently, it has been demonstrated that Secondary Lymphoid-tissue Chemokine (SLC) is constitutively expressed in secondary lymphoid organs and controls the homing of naive T-cells and mature dendritic cells. By screening cDNA isolated from ischemic mouse brain, we found expression of SLC mRNA 6 h up to 4 days after the onset of ischemia. In situ(More)
Induction of tumor necrosis factor alpha was studied in the brain of rats after focal cerebral ischaemia by occlusion of the left middle cerebral artery. Using a specific antisense riboprobe for in situ hybridization histochemistry, cells positive for tumor necrosis factor alpha messenger RNA were detected within 30 min in the brain regions known to be(More)
The expression of interleukin-1 beta (IL-1 beta) mRNA in the brain in response to cerebral ischaemia in rats was examined using in situ hybridization histochemistry. Focal cerebral ischaemia was induced in spontaneously hypertensive rats by permanent occlusion of the left middle cerebral artery (MCAO). Whereas no IL-1 beta mRNA could be detected in(More)
Increasing evidence indicates a key role of chemoattractant cytokines in the accumulation of leukocytes in the central nervous system (CNS) during the course of inflammatory processes. Monocyte chemoattractant protein (MCP-1/JE), a member of the beta-chemokine (C-C chemokine) family, functions as a potent chemoattractant and activator for monocytes. We have(More)
The affinity for eight different neurotransmitter receptors of about fourty drugs, used for the treatment of various central nervous system disorders, was determined following in vitro receptor binding assays. Our findings indicate that, in spite of widely varying chemical structures and often poorly understood mechanisms of action, the similarities in the(More)
The pseudo first-order rate constant kf of the creatine kinase (CK) forward reaction as well as the CK forward flux FCK,f have been shown to correlate better with cardiac performance than the steady-state levels of ATP and PCr (Bittl, J. A., and Ingwall, J. S. (1985) J. Biol. Chem. 260, 3512-3517). In order to elucidate the relationship between the CK(More)
Cells of the mononuclear phagocytotic system (MPS) are often found near to or within ischemic tissue and can potentially aggravate cellular damage. Hence, visualization of those cells would allow demarcation of putatively affected from intact tissue. Experimental MRI studies have shown that ultrasmall particles of dextran-coated iron oxide (USPIO) are(More)
Detailed knowledge of similarities and differences between animal models and human stroke is decisive for selecting clinically effective drugs based on efficacy data obtained preclinically. Differences in the temporal evolution of stroke pathologies between animal models and man have been reported. In view of the importance of this issue for the development(More)
Functional magnetic resonance imaging (fMRI) has been applied to study rat focal brain activation induced by intravenous administration of the GABA(A) antagonist bicuculline. Using magnetite nanoparticles as a blood pool contrast agent, local changes in cerebral blood volume (CBV) were assessed with high temporal (10 s) and spatial (0.35 x 0.6 mm(2))(More)
