    Constitutively activated Jak-STAT pathway in T cells transformed with HTLV-I (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-07-07
    Beschreibung: Human T cell lymphotropic virus I (HTLV-I) is the etiological agent for adult T cell leukemia and tropical spastic paraparesis (also termed HTLV-I-associated myelopathy). HTLV-I-infected peripheral blood T cells exhibit an initial phase of interleukin-2 (IL-2)-dependent growth; over time, by an unknown mechanism, the cells become IL-2-independent. Whereas the Jak kinases Jak1 and Jak3 and the signal transducer and activator of transcription proteins Stat3 and Stat5 are activated in normal T cells in response to IL-2, this signaling pathway was constitutively activated in HTLV-I-transformed cells. In HTLV-I-infected cord blood lymphocytes, the transition from IL-2-dependent to IL-2-independent growth correlated with the acquisition of a constitutively activated Jak-STAT pathway, which suggests that this pathway participates in HTLV-I-mediated T cell transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Migone, T S -- Lin, J X -- Cereseto, A -- Mulloy, J C -- O'Shea, J J -- Franchini, G -- Leonard, W J -- New York, N.Y. -- Science. 1995 Jul 7;269(5220):79-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Immunology, National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7604283" target="_blank"〉PubMed〈/a〉

    Role of NK1.1+ T cells in a TH2 response and in immunoglobulin E production (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-12-15
    Beschreibung: Immune responses dominated by interleukin-4 (IL-4)-producing T helper type 2 (TH2) cells or by interferon gamma (IFN-gamma)-producing T helper type 1 (TH1) cells express distinctive protection against infection with different pathogens. Interleukin-4 promotes the differentiation of naive CD4+ T cells into IL-4 producers and suppresses their development into IFN-gamma producers. CD1-specific splenic CD4+NK1.1+ T cells, a numerically minor population, produced IL-4 promptly on in vivo stimulation. This T cell population was essential for the induction of IL-4-producing cells and for switching to immunoglobulin E, an IL-4-dependent event, in response to injection of antibodies to immunoglobulin D.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshimoto, T -- Bendelac, A -- Watson, C -- Hu-Li, J -- Paul, W E -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1845-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, National Institute of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525383" target="_blank"〉PubMed〈/a〉

    Potentiation of transmitter release by ciliary neurotrophic factor requires somatic signaling (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-02-03
    Beschreibung: Neurotrophic factors participate in the development and maintenance of the nervous system. Application of ciliary neurotrophic factor (CNTF), a protein that promotes survival of motor neurons, resulted in an immediate potentiation of spontaneous and impulse-evoked transmitter release at developing neuromuscular synapses in Xenopus cell cultures. When CNTF was applied at the synapse, the onset of the potentiation was slower than that produced by application at the cell body of the presynaptic neuron. The potentiation effect was abolished when the neurite shaft was severed from the cell body. Thus, transmitter secretion from the nerve terminals is under immediate somatic control and can be regulated by CNTF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stoop, R -- Poo, M M -- New York, N.Y. -- Science. 1995 Feb 3;267(5198):695-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Columbia University, New York, NY 10027.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7839148" target="_blank"〉PubMed〈/a〉

    Requirement for TNF-alpha and IL-1 alpha in fetal thymocyte commitment and differentiation (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-06-30
    Beschreibung: CD25 expression occurs early in thymocyte differentiation. The mechanism of induction of CD25 before T cell receptor rearrangement and the importance of this mechanism for T cell development are unknown. In a thymus reconstitution assay, tumor necrosis factor alpha (TNF-alpha) and interleukin-1 alpha (IL-1 alpha), two cytokines produced within the thymic microenvironment, induced CD25 expression on early immature thymocytes. Either TNF-alpha or IL-1 alpha was necessary for further thymocyte maturation and CD4+CD8+ differentiation. In irradiated mice reconstituted with CD117+CD25+ thymocytes, commitment to the T cell lineage was marked by the loss of precursor multipotency.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zuniga-Pflucker, J C -- Jiang, D -- Lenardo, M J -- New York, N.Y. -- Science. 1995 Jun 30;268(5219):1906-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7541554" target="_blank"〉PubMed〈/a〉

    Mutations of keratinocyte transglutaminase in lamellar ichthyosis (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-01-27
    Beschreibung: Lamellar ichthyosis is a severe congenital skin disorder characterized by generalized large scales and variable redness. Affected individuals in three families exhibited drastically reduced keratinocyte transglutaminase (TGK) activity. In two of these families, expression of TGK transcripts was diminished or abnormal and no TGK protein was detected. Homozygous or compound heterozygous mutations of the TGK gene were identified in all families. These data suggest that defects in TGK cause lamellar ichthyosis and that intact cross-linkage of cornified cell envelopes is required for epidermal tissue homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huber, M -- Rettler, I -- Bernasconi, K -- Frenk, E -- Lavrijsen, S P -- Ponec, M -- Bon, A -- Lautenschlager, S -- Schorderet, D F -- Hohl, D -- New York, N.Y. -- Science. 1995 Jan 27;267(5197):525-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, Centre Hospitalier Universitaire Vandois (CHUV), Hopital de Beaumont, Lausanne, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7824952" target="_blank"〉PubMed〈/a〉

    Interaction of papillomavirus E6 oncoproteins with a putative calcium-binding protein (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-07-28
    Beschreibung: Human papillomaviruses (HPVs) are associated with the majority of cervical cancers and encode a transforming protein, E6, that interacts with the tumor suppressor protein p53. Because E6 has p53-independent transforming activity, the yeast two-hybrid system was used to search for other E6-binding proteins. One such protein, E6BP, interacted with cancer-associated HPV E6 and with bovine papillomavirus type 1 (BPV-1) E6. The transforming activity of BPV-1 E6 mutants correlated with their E6BP-binding ability. E6BP is identical to a putative calcium-binding protein, ERC-55, that appears to be localized in the endoplasmic reticulum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, J J -- Reid, C E -- Band, V -- Androphy, E J -- R01CA44174/CA/NCI NIH HHS/ -- R29CA56803/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):529-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, New England Medical Center, Boston, MA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624774" target="_blank"〉PubMed〈/a〉

    Generation of memory B cells and plasma cells in vitro (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-05-05
    Beschreibung: After germinal center B cells undergo somatic mutation and antigen selection, they become either memory B cells or plasma cells, but the signal requirements that control entry into either pathway have been unclear. When purified human germinal center cells were cultured with interleukin-2, interleukin-10, and cells expressing CD40 ligand, cells with characteristics of memory B cells were generated. Removal of CD40 ligand from the system resulted in terminal differentiation of germinal center B cells into cells with the characteristics of plasma cells. These results indicate that CD40 ligand directs the differentiation of germinal center B cells toward memory B cells rather than toward plasma cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arpin, C -- Dechanet, J -- Van Kooten, C -- Merville, P -- Grouard, G -- Briere, F -- Banchereau, J -- Liu, Y J -- New York, N.Y. -- Science. 1995 May 5;268(5211):720-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Schering-Plough, Laboratory for Immunological Research, Dardilly, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7537388" target="_blank"〉PubMed〈/a〉

    Induction of MHC class I genes in neurons (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-07-28
    Beschreibung: Whether neurons express major histocompatibility complex (MHC) class I genes has not been firmly established. The techniques of confocal laser microscopy, patch clamp electrophysiology, and reverse transcriptase-polymerase chain reaction were combined here to directly examine the inducibility of MHC class I genes in individual cultured rat hippocampal neurons. Transcription of MHC class I genes was very rare in neurons with spontaneous action potentials. In electrically silent neurons, transcription was noted, with expression of beta 2-microglobulin under tighter control than in class I heavy chain molecules. Surface expression of class I molecules occurred only in electrically silent neurons treated with interferon gamma. Immunosurveillance by cytotoxic T cells may be focused on functionally impaired neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Neumann, H -- Cavalie, A -- Jenne, D E -- Wekerle, H -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):549-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroimmunology, Max Planck Institute for Psychiatry, Martinsried, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624779" target="_blank"〉PubMed〈/a〉
