    Description: The pathogenesis of asthma reflects, in part, the activity of T cell cytokines. Murine models support participation of interleukin-4 (IL-4) and the IL-4 receptor in asthma. Selective neutralization of IL-13, a cytokine related to IL-4 that also binds to the alpha chain of the IL-4 receptor, ameliorated the asthma phenotype, including airway hyperresponsiveness, eosinophil recruitment, and mucus overproduction. Administration of either IL-13 or IL-4 conferred an asthma-like phenotype to nonimmunized T cell-deficient mice by an IL-4 receptor alpha chain-dependent pathway. This pathway may underlie the genetic associations of asthma with both the human 5q31 locus and the IL-4 receptor.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3897229/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3897229/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grunig, G -- Warnock, M -- Wakil, A E -- Venkayya, R -- Brombacher, F -- Rennick, D M -- Sheppard, D -- Mohrs, M -- Donaldson, D D -- Locksley, R M -- Corry, D B -- 03344/PHS HHS/ -- 47412/PHS HHS/ -- K08 HL003344/HL/NHLBI NIH HHS/ -- T32 HL07185/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1998 Dec 18;282(5397):2261-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, San Francisco General Hospital, University of California San Francisco, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9856950" target="_blank"〉PubMed〈/a〉

    Description: Endoglin is a transforming growth factor-beta (TGF-beta) binding protein expressed on the surface of endothelial cells. Loss-of-function mutations in the human endoglin gene ENG cause hereditary hemorrhagic telangiectasia (HHT1), a disease characterized by vascular malformations. Here it is shown that by gestational day 11.5, mice lacking endoglin die from defective vascular development. However, in contrast to mice lacking TGF-beta, vasculogenesis was unaffected. Loss of endoglin caused poor vascular smooth muscle development and arrested endothelial remodeling. These results demonstrate that endoglin is essential for angiogenesis and suggest a pathogenic mechanism for HHT1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, D Y -- Sorensen, L K -- Brooke, B S -- Urness, L D -- Davis, E C -- Taylor, D G -- Boak, B B -- Wendel, D P -- K08 HL03490-03/HL/NHLBI NIH HHS/ -- T35 HL07744-06/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1999 May 28;284(5419):1534-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Human Molecular Biology and Genetics, Department of Human Genetics, Howard Hughes Medical Institute, University of Utah, Salt Lake City, UT 84112-5330, USA. dean.li@hci.utah.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10348742" target="_blank"〉PubMed〈/a〉

    Description: In sexual transmission of simian immunodeficiency virus, and early and later stages of human immunodeficiency virus-type 1 (HIV-1) infection, both viruses were found to replicate predominantly in CD4(+) T cells at the portal of entry and in lymphoid tissues. Infection was propagated not only in activated and proliferating T cells but also, surprisingly, in resting T cells. The infected proliferating cells correspond to the short-lived population that produces the bulk of HIV-1. Most of the HIV-1-infected resting T cells persisted after antiretroviral therapy. Latently and chronically infected cells that may be derived from this population pose challenges to eradicating infection and developing an effective vaccine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Z -- Schuler, T -- Zupancic, M -- Wietgrefe, S -- Staskus, K A -- Reimann, K A -- Reinhart, T A -- Rogan, M -- Cavert, W -- Miller, C J -- Veazey, R S -- Notermans, D -- Little, S -- Danner, S A -- Richman, D D -- Havlir, D -- Wong, J -- Jordan, H L -- Schacker, T W -- Racz, P -- Tenner-Racz, K -- Letvin, N L -- Wolinsky, S -- Haase, A T -- AI 28246/AI/NIAID NIH HHS/ -- AI 38565/AI/NIAID NIH HHS/ -- RR 00168/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1999 Nov 12;286(5443):1353-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Minnesota Medical School, Minneapolis, MN 55455, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10558989" target="_blank"〉PubMed〈/a〉

    Description: Self-renewing, totipotent embryonic stem (ES) cells may provide a virtually unlimited donor source for transplantation. A protocol that permits the in vitro generation of precursors for oligodendrocytes and astrocytes from ES cells was devised. Transplantation in a rat model of a human myelin disease shows that these ES cell-derived precursors interact with host neurons and efficiently myelinate axons in brain and spinal cord. Thus, ES cells can serve as a valuable source of cell type-specific somatic precursors for neural transplantation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brustle, O -- Jones, K N -- Learish, R D -- Karram, K -- Choudhary, K -- Wiestler, O D -- Duncan, I D -- McKay, R D -- NS33710/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1999 Jul 30;285(5428):754-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuropathology, University of Bonn Medical Center, Sigmund-Freud-Strasse 25, 53105 Bonn, Germany. brustle@uni-bonn.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10427001" target="_blank"〉PubMed〈/a〉

    Description: The tumor necrosis factor (TNF) superfamily of cytokines includes both soluble and membrane-bound proteins that regulate immune responses. A member of the human TNF family, BLyS (B lymphocyte stimulator), was identified that induced B cell proliferation and immunoglobulin secretion. BLyS expression on human monocytes could be up-regulated by interferon-gamma. Soluble BLyS functioned as a potent B cell growth factor in costimulation assays. Administration of soluble recombinant BLyS to mice disrupted splenic B and T cell zones and resulted in elevated serum immunoglobulin concentrations. The B cell tropism of BLyS is consistent with its receptor expression on B-lineage cells. The biological profile of BLyS suggests it is involved in monocyte-driven B cell activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moore, P A -- Belvedere, O -- Orr, A -- Pieri, K -- LaFleur, D W -- Feng, P -- Soppet, D -- Charters, M -- Gentz, R -- Parmelee, D -- Li, Y -- Galperina, O -- Giri, J -- Roschke, V -- Nardelli, B -- Carrell, J -- Sosnovtseva, S -- Greenfield, W -- Ruben, S M -- Olsen, H S -- Fikes, J -- Hilbert, D M -- New York, N.Y. -- Science. 1999 Jul 9;285(5425):260-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genome Sciences, 9410 Key West Avenue, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10398604" target="_blank"〉PubMed〈/a〉

    Description: Usher syndrome type IIa (OMIM 276901), an autosomal recessive disorder characterized by moderate to severe sensorineural hearing loss and progressive retinitis pigmentosa, maps to the long arm of human chromosome 1q41 between markers AFM268ZD1 and AFM144XF2. Three biologically important mutations in Usher syndrome type IIa patients were identified in a gene (USH2A) isolated from this critical region. The USH2A gene encodes a protein with a predicted size of 171.5 kilodaltons that has laminin epidermal growth factor and fibronectin type III motifs; these motifs are most commonly observed in proteins comprising components of the basal lamina and extracellular matrixes and in cell adhesion molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eudy, J D -- Weston, M D -- Yao, S -- Hoover, D M -- Rehm, H L -- Ma-Edmonds, M -- Yan, D -- Ahmad, I -- Cheng, J J -- Ayuso, C -- Cremers, C -- Davenport, S -- Moller, C -- Talmadge, C B -- Beisel, K W -- Tamayo, M -- Morton, C C -- Swaroop, A -- Kimberling, W J -- Sumegi, J -- 5PO1 DC01813-05/DC/NIDCD NIH HHS/ -- DC03402/DC/NIDCD NIH HHS/ -- EY07003/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1998 Jun 12;280(5370):1753-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology and Microbiology, University of Nebraska Medical Center, Omaha, NE 68198, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9624053" target="_blank"〉PubMed〈/a〉

    Description: Dopaminergic neurons exert a major modulatory effect on the forebrain. Dopamine and adenosine 3',5'-monophosphate-regulated phosphoprotein (32 kilodaltons) (DARPP-32), which is enriched in all neurons that receive a dopaminergic input, is converted in response to dopamine into a potent protein phosphatase inhibitor. Mice generated to contain a targeted disruption of the DARPP-32 gene showed profound deficits in their molecular, electrophysiological, and behavioral responses to dopamine, drugs of abuse, and antipsychotic medication. The results show that DARPP-32 plays a central role in regulating the efficacy of dopaminergic neurotransmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fienberg, A A -- Hiroi, N -- Mermelstein, P G -- Song, W -- Snyder, G L -- Nishi, A -- Cheramy, A -- O'Callaghan, J P -- Miller, D B -- Cole, D G -- Corbett, R -- Haile, C N -- Cooper, D C -- Onn, S P -- Grace, A A -- Ouimet, C C -- White, F J -- Hyman, S E -- Surmeier, D J -- Girault, J -- Nestler, E J -- Greengard, P -- DA 08227/DA/NIDA NIH HHS/ -- DA10044/DA/NIDA NIH HHS/ -- F31 DA005794/DA/NIDA NIH HHS/ -- MH40899/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1998 Aug 7;281(5378):838-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular and Cellular Neuroscience, The Rockefeller University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9694658" target="_blank"〉PubMed〈/a〉

    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: A blood donor infected with human immunodeficiency virus-type 1 (HIV-1) and a cohort of six blood or blood product recipients infected from this donor remain free of HIV-1-related disease with stable and normal CD4 lymphocyte counts 10 to 14 years after infection. HIV-1 sequences from either virus isolates or patient peripheral blood mononuclear cells had similar deletions in the nef gene and in the region of overlap of nef and the U3 region of the long terminal repeat (LTR). Full-length sequencing of one isolate genome and amplification of selected HIV-1 genome regions from other cohort members revealed no other abnormalities of obvious functional significance. These data show that survival after HIV infection can be determined by the HIV genome and support the importance of nef or the U3 region of the LTR in determining the pathogenicity of HIV-1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deacon, N J -- Tsykin, A -- Solomon, A -- Smith, K -- Ludford-Menting, M -- Hooker, D J -- McPhee, D A -- Greenway, A L -- Ellett, A -- Chatfield, C -- Lawson, V A -- Crowe, S -- Maerz, A -- Sonza, S -- Learmont, J -- Sullivan, J S -- Cunningham, A -- Dwyer, D -- Dowton, D -- Mills, J -- New York, N.Y. -- Science. 1995 Nov 10;270(5238):988-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉AIDS Molecular Biology Unit, Macfarlane Burnet Centre for Medical Research, Fairfield, Victoria, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481804" target="_blank"〉PubMed〈/a〉

    Description: Space-based and airborne coherent Doppler lidars designed for measuring global tropospheric wind profiles in cloud-free air rely on backscatter, beta from aerosols acting as passive wind tracers. Aerosol beta distribution in the vertical can vary over as much as 5-6 orders of magnitude. Thus, the design of a wave length-specific, space-borne or airborne lidar must account for the magnitude of 8 in the region or features of interest. The SPAce Readiness Coherent Lidar Experiment under development by the National Aeronautics and Space Administration (NASA) and scheduled for launch on the Space Shuttle in 2001, will demonstrate wind measurements from space using a solid-state 2 micrometer coherent Doppler lidar. Consequently, there is a critical need to understand variability of aerosol beta at 2.1 micrometers, to evaluate signal detection under varying aerosol loading conditions. Although few direct measurements of beta at 2.1 micrometers exist, extensive datasets, including climatologies in widely-separated locations, do exist for other wavelengths based on CO2 and Nd:YAG lidars. Datasets also exist for the associated microphysical and chemical properties. An example of a multi-parametric dataset is that of the NASA GLObal Backscatter Experiment (GLOBE) in 1990 in which aerosol chemistry and size distributions were measured concurrently with multi-wavelength lidar backscatter observations. More recently, continuous-wave (CW) lidar backscatter measurements at mid-infrared wavelengths have been made during the Multicenter Airborne Coherent Atmospheric Wind Sensor (MACAWS) experiment in 1995. Using Lorenz-Mie theory, these datasets have been used to develop a method to convert lidar backscatter to the 2.1 micrometer wavelength. This paper presents comparison of modeled backscatter at wavelengths for which backscatter measurements exist including converted beta (sub 2.1).
