    Beschreibung: Certain inflammatory stimuli render cultured human vascular endothelial cells hyperadhesive for neutrophils. This state is transient and reversible, in part because activated endothelial cells secrete a leukocyte adhesion inhibitor (LAI). LAI was identified as endothelial interleukin-8 (IL-8), the predominant species of which is an extended amino-terminal IL-8 variant. At nanomolar concentrations, purified endothelial IL-8 and recombinant human IL-8 inhibit neutrophil adhesion to cytokine-activated endothelial monolayers and protect these monolayers from neutrophil-mediated damage. These findings suggest that endothelial-derived IL-8 may function to attenuate inflammatory events at the interface between vessel wall and blood.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gimbrone, M A Jr -- Obin, M S -- Brock, A F -- Luis, E A -- Hass, P E -- Hebert, C A -- Yip, Y K -- Leung, D W -- Lowe, D G -- Kohr, W J -- P01-HL-36028/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Dec 22;246(4937):1601-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2688092" target="_blank"〉PubMed〈/a〉

    Beschreibung: The N-methyl-D-aspartate (NMDA) class of excitatory amino acid receptors regulates the strength and stability of excitatory synapses and appears to play a major role in excitotoxic neuronal death associated with stroke and epilepsy. The conductance increase gated by NMDA is potentiated by the amino acid glycine, which acts at an allosteric site tightly coupled to the NMDA receptor. Indole-2-carboxylic acid (I2CA) specifically and competitively inhibits the potentiation by glycine of NMDA-gated current. In solutions containing low levels of glycine, I2CA completely blocks the response to NMDA, suggesting that NMDA alone is not sufficient for channel activation. I2CA will be useful for defining the interaction of glycine with NMDA receptors and for determining the in vivo role of glycine in excitotoxicity and synapse stabilization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huettner, J E -- HL-35034/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Mar 24;243(4898):1611-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2467381" target="_blank"〉PubMed〈/a〉

    Beschreibung: The murine acquired immunodeficiency syndrome is induced by a defective retrovirus. To study the role of virus replication in this disease, helper-free stocks of defective Duplan virus were produced. These stocks were highly pathogenic in absence of detectable replicating murine leukemia viruses (MuLVs) other than xenotropic MuLV. They induced expansion of the infected cell population (over 1000-fold), and this cell expansion was oligoclonal in origin and, most likely, arose through cell division. These results suggest that this defective virus is oncogenic, inducing a primary neoplasia associated with an acquired immunodeficiency syndrome as a paraneoplastic syndrome. These data emphasize the need to determine whether virus replication is necessary for the progression of other immunodeficiency diseases, including acquired immunodeficiency syndrome, and whether these diseases also represent paraneoplastic syndromes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, M -- Simard, C -- Jolicoeur, P -- New York, N.Y. -- Science. 1989 Dec 22;246(4937):1614-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Biology, Clinical Research Institute of Montreal, Quebec, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2480643" target="_blank"〉PubMed〈/a〉

    Beschreibung: Voltage-dependent Ca2+ channels (VDCCs) are modulators of synaptic plasticity, oscillatory behavior, and rhythmic firing in brain regions such as the hippocampus. The distribution and lateral mobility of VDCCs on CA1 hippocampal neurons have been determined with biologically active fluorescent and biotinylated derivatives of the selective probe omega-conotoxin in conjunction with circular dityndallism, digital fluorescence imaging, and photobleach recovery microscopy. On noninnervated cell bodies, VDCCs were found to be organized in multiple clusters, whereas after innervation the VDCCs were concentrated and immobilized at synaptic contact sites. On dendrites, VDCC distribution was punctate and was interrupted by extensive bare regions or abruptly terminated. More than 85% of the dendritic VDCCs were found to be immobile by fluorescence photobleach recovery. Thus, before synaptic contact, specific mechanisms target, segregate, and immobilize VDCCs to neuronal cell bodies and to specialized dendritic sites. Regulation of this distribution may be critical in determining the firing activity and integrative properties of hippocampal CA1 neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, O T -- Kunze, D L -- Angelides, K J -- NS01218/NS/NINDS NIH HHS/ -- NS23575/NS/NINDS NIH HHS/ -- NS24606/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 9;244(4909):1189-93.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Molecular Biophysics, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2543080" target="_blank"〉PubMed〈/a〉

    Beschreibung: DNA and nuclear proteins were transferred into cells simultaneously at more than 95% efficiency by means of vesicle complexes. The DNA was rapidly transported into the nuclei of cultured cells, and its expression reached a maximum within 6 to 8 hours after its introduction. Moreover, when the plasmid DNA and nuclear protein were cointroduced into nondividing cells in rat liver by injection into the portal veins of adult rats, the plasmid DNA was carried into liver cell nuclei efficiently by nuclear protein. The expression of the DNA in adult rat liver, on introduction of the DNA with nuclear protein, was more than five times as great as with nonnuclear protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaneda, Y -- Iwai, K -- Uchida, T -- New York, N.Y. -- Science. 1989 Jan 20;243(4889):375-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Molecular and Cellular Biology, Osaka University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2911748" target="_blank"〉PubMed〈/a〉

    Beschreibung: Mouse 3T3 cell lines capable of constitutively synthesizing an RNA complementary to the messenger RNA encoding TIMP, tissue inhibitor of metalloproteinases, were constructed by transfection with appropriate plasmid constructs. Many of the lines were down-modulated for TIMP messenger RNA levels and secreted less TIMP into the culture medium. In comparison to noninvasive, nontumorigenic controls, these cells not only were invasive in a human amnion invasion assay, but also were tumorigenic and metastatic in athymic mice. These results indicate that TIMP suppresses oncogenicity, at least in immortal murine 3T3 cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Khokha, R -- Waterhouse, P -- Yagel, S -- Lala, P K -- Overall, C M -- Norton, G -- Denhardt, D T -- New York, N.Y. -- Science. 1989 Feb 17;243(4893):947-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Western Ontario, London, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2465572" target="_blank"〉PubMed〈/a〉

    Beschreibung: Basic fibroblast growth factor (bFGF) participates in many processes including early developmental events, angiogenesis, wound healing, and maintenance of neuronal cell viability. A 130-kilodalton protein was isolated on the basis of its ability to specifically bind to bFGF. A complementary DNA clone was isolated with an oligonucleotide probe corresponding to determined amino acid sequences of tryptic peptide fragments of the purified protein. The putative bFGF receptor encoded by this complementary DNA is a transmembrane protein that contains three extracellular immunoglobulin-like domains, an unusual acidic region, and an intracellular tyrosine kinase domain. These domains are arranged in a pattern that is different from that of any growth factor receptor described.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, P L -- Johnson, D E -- Cousens, L S -- Fried, V A -- Williams, L T -- CA 21765/CA/NCI NIH HHS/ -- R01 HL32898/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jul 7;245(4913):57-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2544996" target="_blank"〉PubMed〈/a〉

    Beschreibung: The patch-clamp technique was used to examine the effects of atrial natriuretic peptide (ANP) and its second messenger guanosine 3',5'-monophosphate (cGMP) on an amiloride-sensitive cation channel in the apical membrane of renal inner medullary collecting duct cells. Both ANP (10(-11) M) and dibutyryl guanosine 3',5'-monophosphate (10(-4) M) inhibited the channel in cell-attached patches, and cGMP (10(-5) M) inhibited the channel in inside-out patches. The inner medullary collecting duct is the first tissue in which ANP, via its second messenger cGMP, has been shown to regulate single ion channels. The results suggest that the natriuretic action of ANP is related in part to cGMP-mediated inhibition of electrogenic Na+ absorption by the inner medullary collecting duct.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Light, D B -- Schwiebert, E M -- Karlson, K H -- Stanton, B A -- DK-34533/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 20;243(4889):383-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, Dartmouth Medical School, Hanover, NH 03756.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2463673" target="_blank"〉PubMed〈/a〉

    Beschreibung: Astrocytes have many neuronal characteristics, such as neurotransmitter receptors, ion channels, and neurotransmitter uptake systems. Cultured astrocytes were shown to express certain neuropeptide genes, with specificity for both the gene expressed and the brain region from which the cells were prepared. Somatostatin messenger RNA and peptides were detected only in cerebellar astrocytes, whereas proenkephalin messenger RNA and enkephalin peptides were present in astrocytes of cortex, cerebellum, and striatum. Cholecystokinin was not expressed in any of the cells. These results support the hypothesis that peptides synthesized in astrocytes may play a role in the development of the central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shinoda, H -- Marini, A M -- Cosi, C -- Schwartz, J P -- New York, N.Y. -- Science. 1989 Jul 28;245(4916):415-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Clinical Neuroscience Branch, National Institute of Neurological Disorders and Stroke, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2569236" target="_blank"〉PubMed〈/a〉

    Beschreibung: Clonal cultures and monoclonal antibodies against a lineage-specific epitope, stage-specific embryonic antigen-1 (SSEA-1) were used to analyze the commitment of quail neural crest cells to the sensory neuron pathway. There were two distinct populations of sensory cells at the time of gangliogenesis. Postmitotic neuroblasts that remained in close association with the neural tube coexisted with a large number of pluripotent cells that formed the leading edge of the emigrating cells and gave rise to sensory and autonomic neuroblasts and to melanocytes. The data suggest a dual origin of spinal sensory neuroblasts and a predominantly late divergence of the autonomic and sensory lineages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sieber-Blum, M -- HD21423/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1989 Mar 24;243(4898):1608-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Cellular Biology, Medical College of Wisconsin, Milwaukee 53226.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2564699" target="_blank"〉PubMed〈/a〉
