    Description: A common single-nucleotide polymorphism in the brain-derived neurotrophic factor (BDNF) gene, a methionine (Met) substitution for valine (Val) at codon 66 (Val66Met), is associated with alterations in brain anatomy and memory, but its relevance to clinical disorders is unclear. We generated a variant BDNF mouse (BDNF(Met/Met)) that reproduces the phenotypic hallmarks in humans with the variant allele. BDNF(Met) was expressed in brain at normal levels, but its secretion from neurons was defective. When placed in stressful settings, BDNF(Met/Met) mice exhibited increased anxiety-related behaviors that were not normalized by the antidepressant, fluoxetine. A variant BDNF may thus play a key role in genetic predispositions to anxiety and depressive disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1880880/" 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/PMC1880880/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Zhe-Yu -- Jing, Deqiang -- Bath, Kevin G -- Ieraci, Alessandro -- Khan, Tanvir -- Siao, Chia-Jen -- Herrera, Daniel G -- Toth, Miklos -- Yang, Chingwen -- McEwen, Bruce S -- Hempstead, Barbara L -- Lee, Francis S -- MH060478/MH/NIMH NIH HHS/ -- MH068850/MH/NIMH NIH HHS/ -- NS052819/NS/NINDS NIH HHS/ -- NS30687/NS/NINDS NIH HHS/ -- R01 NS052819/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 Oct 6;314(5796):140-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, Weill Medical College of Cornell University, New York, NY 10021, USA. zheyuchen@sdu.edu.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17023662" target="_blank"〉PubMed〈/a〉

    Description: IRAK-4 is a protein kinase that is pivotal in mediating signals for innate immune responses. Here, we report that IRAK-4 signaling is also essential for eliciting adaptive immune responses. Thus, in the absence of IRAK-4, in vivo T cell responses were significantly impaired. Upon T cell receptor stimulation, IRAK-4 is recruited to T cell lipid rafts, where it induces downstream signals, including protein kinase C activation through the association with Zap70. This signaling pathway was found to be required for optimal activation of nuclear factor kappaB. Our findings suggest that T cells use this critical regulator of innate immunity for the development of acquired immunity, suggesting that IRAK-4 may be involved in direct signal cross talk between the two systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suzuki, Nobutaka -- Suzuki, Shinobu -- Millar, Douglas G -- Unno, Midori -- Hara, Hiromitsu -- Calzascia, Thomas -- Yamasaki, Sho -- Yokosuka, Tadashi -- Chen, Nien-Jung -- Elford, Alisha R -- Suzuki, Jun-Ichiro -- Takeuchi, Arata -- Mirtsos, Christine -- Bouchard, Denis -- Ohashi, Pamela S -- Yeh, Wen-Chen -- Saito, Takashi -- New York, N.Y. -- Science. 2006 Mar 31;311(5769):1927-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Cell Signaling, RIKEN Research Center for Allergy and Immunology, 1-7-22 Suehiro-cho, Tsurumi-ku, Yokohama City, Kanagawa 230-0045, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16574867" target="_blank"〉PubMed〈/a〉

    Description: Norepinephrine (NE) is widely implicated in opiate withdrawal, but much less is known about its role in opiate-induced locomotion and reward. In mice lacking dopamine beta-hydroxylase (DBH), an enzyme critical for NE synthesis, we found that NE was necessary for morphine-induced conditioned place preference (CPP; a measure of reward) and locomotion. These deficits were rescued by systemic NE restoration. Viral restoration of DBH expression in the nucleus tractus solitarius, but not in the locus coeruleus, restored CPP for morphine. Morphine-induced locomotion was partially restored by DBH expression in either brain region. These data suggest that NE signaling by the nucleus tractus solitarius is necessary for morphine reward.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olson, Valerie G -- Heusner, Carrie L -- Bland, Ross J -- During, Matthew J -- Weinshenker, David -- Palmiter, Richard D -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):1017-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484499" target="_blank"〉PubMed〈/a〉

    Description: Mice experiencing repeated aggression develop a long-lasting aversion to social contact, which can be normalized by chronic, but not acute, administration of antidepressant. Using viral-mediated, mesolimbic dopamine pathway-specific knockdown of brain-derived neurotrophic factor (BDNF), we showed that BDNF is required for the development of this experience-dependent social aversion. Gene profiling in the nucleus accumbens indicates that local knockdown of BDNF obliterates most of the effects of repeated aggression on gene expression within this circuit, with similar effects being produced by chronic treatment with antidepressant. These results establish an essential role for BDNF in mediating long-term neural and behavioral plasticity in response to aversive social experiences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berton, Olivier -- McClung, Colleen A -- Dileone, Ralph J -- Krishnan, Vaishnav -- Renthal, William -- Russo, Scott J -- Graham, Danielle -- Tsankova, Nadia M -- Bolanos, Carlos A -- Rios, Maribel -- Monteggia, Lisa M -- Self, David W -- Nestler, Eric J -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):864-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry and Center for Basic Neuroscience, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390-9070, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469931" target="_blank"〉PubMed〈/a〉

    Description: The contribution of bone marrow-derived circulating endothelial progenitor cells (CEPs) to tumor angiogenesis has been controversial, primarily because of their low numbers in blood vessels of untreated tumors. We show that treatment of tumor-bearing mice with vascular disrupting agents (VDAs) leads to an acute mobilization of CEPs, which home to the viable tumor rim that characteristically remains after such therapy. Disruption of this CEP spike by antiangiogenic drugs or by genetic manipulation resulted in marked reductions in tumor rim size and blood flow as well as enhanced VDA antitumor activity. These findings also provide a mechanistic rationale for the enhanced efficacy of VDAs when combined with antiangiogenic drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shaked, Yuval -- Ciarrocchi, Alessia -- Franco, Marcela -- Lee, Christina R -- Man, Shan -- Cheung, Alison M -- Hicklin, Daniel J -- Chaplin, David -- Foster, F Stuart -- Benezra, Robert -- Kerbel, Robert S -- CA-41233/CA/NCI NIH HHS/ -- R01 CA-107429/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 22;313(5794):1785-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology Research, Sunnybrook Health Sciences Centre, Toronto, Ontario M4N 3M5, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16990548" target="_blank"〉PubMed〈/a〉

    Description: The liver can regenerate its volume after major tissue loss. In a mouse model of liver regeneration, thrombocytopenia, or impaired platelet activity resulted in the failure to initiate cellular proliferation in the liver. Platelets are major carriers of serotonin in the blood. In thrombocytopenic mice, a serotonin agonist reconstituted liver proliferation. The expression of 5-HT2A and 2B subtype serotonin receptors in the liver increased after hepatectomy. Antagonists of 5-HT2A and 2B receptors inhibited liver regeneration. Liver regeneration was also blunted in mice lacking tryptophan hydroxylase 1, which is the rate-limiting enzyme for the synthesis of peripheral serotonin. This failure of regeneration was rescued by reloading serotonin-free platelets with a serotonin precursor molecule. These results suggest that platelet-derived serotonin is involved in the initiation of liver regeneration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lesurtel, Mickael -- Graf, Rolf -- Aleil, Boris -- Walther, Diego J -- Tian, Yinghua -- Jochum, Wolfram -- Gachet, Christian -- Bader, Michael -- Clavien, Pierre-Alain -- New York, N.Y. -- Science. 2006 Apr 7;312(5770):104-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Visceral and Transplantation Surgery, University Hospital of Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16601191" target="_blank"〉PubMed〈/a〉

    Description: GABA (gamma-aminobutyric acid), the major inhibitory transmitter in the brain, goes through a transitory phase of excitation during development. The excitatory phase promotes neuronal growth and integration into circuits. We show here that spontaneous nicotinic cholinergic activity is responsible for terminating GABAergic excitation and initiating inhibition. It does so by changing chloride transporter levels, shifting the driving force on GABA-induced currents. The timing of the transition is critical, because the two phases of GABAergic signaling provide contrasting developmental instructions. Synergistic with nicotinic excitation, GABAergic inhibition constrains neuronal morphology and innervation. The results reveal a multitiered activity-dependent strategy controlling neuronal development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Zhaoping -- Neff, Robert A -- Berg, Darwin K -- NS012601/NS/NINDS NIH HHS/ -- NS035469/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1610-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biological Sciences, University of California, San Diego, 9500 Gilman Drive, La Jolla, CA 92093-0357, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158331" target="_blank"〉PubMed〈/a〉

    Description: The thymus organ supports the development of T cells and is located in the thorax. Here, we report the existence of a second thymus in the mouse neck, which develops after birth and grows to the size of a small lymph node. The cervical thymus had a typical medulla-cortex structure, was found to support T cell development, and could correct T cell deficiency in athymic nude mice upon transplantation. The identification of a regular second thymus in the mouse may provide evolutionary links to thymus organogenesis in other vertebrates and suggests a need to reconsider the effect of thoracic thymectomy on de novo T cell production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Terszowski, Grzegorz -- Muller, Susanna M -- Bleul, Conrad C -- Blum, Carmen -- Schirmbeck, Reinhold -- Reimann, Jorg -- Pasquier, Louis Du -- Amagai, Takashi -- Boehm, Thomas -- Rodewald, Hans-Reimer -- New York, N.Y. -- Science. 2006 Apr 14;312(5771):284-7.

    Description: The energy that sustains cancer cells is derived preferentially from glycolysis. This metabolic change, the Warburg effect, was one of the first alterations in cancer cells recognized as conferring a survival advantage. Here, we show that p53, one of the most frequently mutated genes in cancers, modulates the balance between the utilization of respiratory and glycolytic pathways. We identify Synthesis of Cytochrome c Oxidase 2 (SCO2) as the downstream mediator of this effect in mice and human cancer cell lines. SCO2 is critical for regulating the cytochrome c oxidase (COX) complex, the major site of oxygen utilization in the eukaryotic cell. Disruption of the SCO2 gene in human cancer cells with wild-type p53 recapitulated the metabolic switch toward glycolysis that is exhibited by p53-deficient cells. That SCO2 couples p53 to mitochondrial respiration provides a possible explanation for the Warburg effect and offers new clues as to how p53 might affect aging and metabolism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matoba, Satoaki -- Kang, Ju-Gyeong -- Patino, Willmar D -- Wragg, Andrew -- Boehm, Manfred -- Gavrilova, Oksana -- Hurley, Paula J -- Bunz, Fred -- Hwang, Paul M -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 16;312(5780):1650-3.

    Description: The germinal center (GC) is an important site for the generation and selection of B cells bearing high-affinity antibodies, yet GC cell migration and interaction dynamics have not been directly observed. Using two-photon microscopy of mouse lymph nodes, we revealed that GC B cells are highly motile and extend long cell processes. They transited between GC dark and light zones and divided in both regions, although these B cells resided for only several hours in the light zone where antigen is displayed. GC B cells formed few stable contacts with GC T cells despite frequent encounters, and T cells were seen to carry dead B cell blebs. On the basis of these observations, we propose a model in which competition for T cell help plays a more dominant role in the selection of GC B cells than previously appreciated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allen, Christopher D C -- Okada, Takaharu -- Tang, H Lucy -- Cyster, Jason G -- New York, N.Y. -- Science. 2007 Jan 26;315(5811):528-31.
