    Description: Transporter-facilitated uptake of serotonin (5-hydroxytryptamine or 5-HT) has been implicated in anxiety in humans and animal models and is the site of action of widely used uptake-inhibiting antidepressant and antianxiety drugs. Human 5-HT transporter (5-HTT) gene transcription is modulated by a common polymorphism in its upstream regulatory region. The short variant of the polymorphism reduces the transcriptional efficiency of the 5-HTT gene promoter, resulting in decreased 5-HTT expression and 5-HT uptake in lymphoblasts. Association studies in two independent samples totaling 505 individuals revealed that the 5-HTT polymorphism accounts for 3 to 4 percent of total variation and 7 to 9 percent of inherited variance in anxiety-related personality traits in individuals as well as sibships.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lesch, K P -- Bengel, D -- Heils, A -- Sabol, S Z -- Greenberg, B D -- Petri, S -- Benjamin, J -- Muller, C R -- Hamer, D H -- Murphy, D L -- New York, N.Y. -- Science. 1996 Nov 29;274(5292):1527-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of Wurzburg, Fuchsleinstrasse 15, 97080 Wurzburg, Germany. kplesch@rzbox.uni-wuerzburg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8929413" target="_blank"〉PubMed〈/a〉

    Description: Vaccination with naked DNA elicits cellular and humoral immune responses that have a T helper cell type 1 bias. However, plasmid vectors expressing large amounts of gene product do not necessarily induce immune responses to the encoded antigens. Instead, the immunogenicity of plasmid DNA (pDNA) requires short immunostimulatory DNA sequences (ISS) that contain a CpG dinucleotide in a particular base context. Human monocytes transfected with pDNA or double-stranded oligonucleotides containing the ISS, but not those transfected with ISS-deficient pDNA or oligonucleotides, transcribed large amounts of interferon-alpha, interferon-beta, and interleukin-12. Although ISS are necessary for gene vaccination, they down-regulate gene expression and thus may interfere with gene replacement therapy by inducing proinflammatory cytokines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sato, Y -- Roman, M -- Tighe, H -- Lee, D -- Corr, M -- Nguyen, M D -- Silverman, G J -- Lotz, M -- Carson, D A -- Raz, E -- AI36214/AI/NIAID NIH HHS/ -- AI37305/AI/NIAID NIH HHS/ -- AR41897/AR/NIAMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1996 Jul 19;273(5273):352-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine and The Sam and Rose Stein Institute for Research on Aging, University of California, San Diego, 9500 Gilman Drive, La Jolla, CA 92093-0663, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8662521" target="_blank"〉PubMed〈/a〉

    Description: Ion acceleration and flux increase associated with substorm energetic particle injections are investigated on the basis of geosynchronous observations and test proton orbits in the dynamic fields of a three dimensional magnetohydrodynamic simulation of neutral line formation and dipolarization in the magnetotail. The energetic particle flux changes obtained from the test particle orbits agree well with observations that demonstrate rapid ion flux increases at energies of above 20 keV. The injection region inferred from the test particles has a sharp earthward boundary and a sharp ragged tailward boundary. The earthward portion of the enhanced ion flux can be traced to the enhanced cross-tail electric field associated with the near-earth x-type neutral line. Due to the rapid earthward motion of accelerated ions away from the neutral line, this boundary is displaced earthward to where the energetic ions become more adiabatic in the stronger dipolar field.

    Description: Using a year's worth of geosynchronous spacecraft data, the substorm associated behavior of the thermal plasma in the plasma sheet in relation to energetic particle injections is reviewed. Five classes of injection events were found: ion injections without accompanying electron injection at 21 local time (LT); ion injection followed a few minutes later by an electron injection at 22 LT; simultaneous ion and electron injection close to midnight; electron injections followed by an ion injection at 01 LT; and pure electron injections at 02 LT. The thermal electrons show a significant increase in temperature and pressure at substorm onset, while the density and thermal ion signatures are typically weak. Energetic ions are found to contribute to the total ion pressure and temperature. Preexisting perpendicular anisotropies in the thermal electrons and ions are reduced during the substorm growth phase, but are re-enhanced after onset.

    Description: Transcription factors of the NFAT family are thought to play a major role in regulating the expression of cytokine genes and other inducible genes during the immune response. The role of NFAT1 was investigated by targeted disruption of the NFAT1 gene. Unexpectedly, cells from NFAT1 -/- mice showed increased primary responses to Leishmania major and mounted increased secondary responses to ovalbumin in vitro. In an in vivo model of allergic inflammation, the accumulation of eosinophils and levels of serum immunoglobulin E were increased in NFAT1 -/- mice. These results suggest that NFAT1 exerts a negative regulatory influence on the immune response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xanthoudakis, S -- Viola, J P -- Shaw, K T -- Luo, C -- Wallace, J D -- Bozza, P T -- Luk, D C -- Curran, T -- Rao, A -- CA42471/CA/NCI NIH HHS/ -- GM46227/GM/NIGMS NIH HHS/ -- P30 CA21765/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1996 May 10;272(5263):892-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurogenetics Program, Department of CNS Research, Hoffmann-LaRoche, Nutley, NJ 07110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8629027" target="_blank"〉PubMed〈/a〉

    Description: HLA-DM (DM) facilitates peptide loading of major histocompatibility complex class II molecules in human cell lines. Mice lacking functional H2-M, the mouse equivalent of DM, have normal amounts of class II molecules at the cell surface, but most of these are associated with invariant chain-derived CLIP peptides. These mice contain large numbers of CD4+ T cells, which is indicative of positive selection in the thymus. Their CD4+ cells were unresponsive to self H2-M-deficient antigen-presenting cells (APCs) but were hyperreactive to wild-type APCs. H2-M-deficient APCs failed to elicit proliferative responses from wild-type T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fung-Leung, W P -- Surh, C D -- Liljedahl, M -- Pang, J -- Leturcq, D -- Peterson, P A -- Webb, S R -- Karlsson, L -- New York, N.Y. -- Science. 1996 Mar 1;271(5253):1278-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉R.

    Description: A second gene for autosomal dominant polycystic kidney disease was identified by positional cloning. Nonsense mutations in this gene (PKD2) segregated with the disease in three PKD2 families. The predicted 968-amino acid sequence of the PKD2 gene product has six transmembrane spans with intracellular amino- and carboxyl-termini. The PKD2 protein has amino acid similarity with PKD1, the Caenorhabditis elegans homolog of PKD1, and the family of voltage-activated calcium (and sodium) channels, and it contains a potential calcium-binding domain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mochizuki, T -- Wu, G -- Hayashi, T -- Xenophontos, S L -- Veldhuisen, B -- Saris, J J -- Reynolds, D M -- Cai, Y -- Gabow, P A -- Pierides, A -- Kimberling, W J -- Breuning, M H -- Deltas, C C -- Peters, D J -- Somlo, S -- DK02015/DK/NIDDK NIH HHS/ -- DK48383/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1996 May 31;272(5266):1339-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Renal Division, Department of Medicine and Molecular Genetics, Albert Einstein College of Medicine, Bronx, NY 10461, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8650545" target="_blank"〉PubMed〈/a〉

    Description: Homozygous weaver mice are profoundly ataxic because of the loss of granule cell neurons during cerebellar development. This granule cell loss appears to be caused by a genetic defect in the pore region (Gly156--〉Ser) of the heterotrimeric guanine nucleotide-binding protein (G protein)-gated inwardly rectifying potassium (K+) channel subunit (GIRK2). A related subunit, GIRK1, associates with GIRK2 to constitute a neuronal G protein-gated inward rectifier K+ channel. The weaver allele of the GIRK2 subunit (wvGIRK2) caused loss of K+ selectivity when expressed either as wvGIRK2 homomultimers or as GIRK1-wvGIRK2 heteromultimers. The mutation also let to loss of sensitivity to G protein betagamma dimers. Expression of wvGIRK2 subunits let to increased cell death, presumably as a result of basal nonselective channel opening.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Navarro, B -- Kennedy, M E -- Velimirovic, B -- Bhat, D -- Peterson, A S -- Clapham, D E -- New York, N.Y. -- Science. 1996 Jun 28;272(5270):1950-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Mayo Foundation, Rochester, Minnesota 55905, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8658170" target="_blank"〉PubMed〈/a〉

    Description: The solution structure of a human immunodeficiency virus type-1 (HIV-1) Rev peptide bound to stem-loop IIB of the Rev response element (RRE) RNA was solved by nuclear magnetic resonance spectroscopy. The Rev peptide has an alpha-helical conformation and binds in the major groove of the RNA near a purine-rich internal loop. Several arginine side chains make base-specific contacts, and an asparagine residue contacts a G.A base pair. The phosphate backbone adjacent to a G.G base pair adopts an unusual structure that allows the peptide to access a widened major groove. The structure formed by the two purine-purine base pairs of the RRE creates a distinctive binding pocket that the peptide can use for specific recognition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Battiste, J L -- Mao, H -- Rao, N S -- Tan, R -- Muhandiram, D R -- Kay, L E -- Frankel, A D -- Williamson, J R -- GM-08344/GM/NIGMS NIH HHS/ -- GM-39589/GM/NIGMS NIH HHS/ -- GM-53320/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1996 Sep 13;273(5281):1547-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8703216" target="_blank"〉PubMed〈/a〉
