    Requirement for Valpha14 NKT cells in IL-12-mediated rejection of tumors (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-12-31
    Description: A lymphocyte subpopulation, the Valpha14 natural killer T (NKT) cells, expresses both NK1.1 and a single invariant T cell receptor encoded by the Valpha14 and Jalpha281 gene segments. Mice with a deletion of the Jalpha281 gene segment were found to exclusively lack this subpopulation. The Valpha14 NKT cell-deficient mice could no longer mediate the interleukin-12 (IL-12)-induced rejection of tumors. Although the antitumor effect of IL-12 was thought to be mediated through natural killer cells and T cells, Valpha14 NKT cells were found to be an essential target of IL-12, and they mediated their cytotoxicity by an NK-like effector mechanism after activation with IL-12.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cui, J -- Shin, T -- Kawano, T -- Sato, H -- Kondo, E -- Toura, I -- Kaneko, Y -- Koseki, H -- Kanno, M -- Taniguchi, M -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1623-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Core Research for Evolutional Science and Technology (CREST) Project, Japan Science and Technology Corporation (JST), 1-8-1 Inohana, Chuo-ku, Chiba, Japan 260.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9374462" target="_blank"〉PubMed〈/a〉

    CD1d-restricted and TCR-mediated activation of valpha14 NKT cells by glycosylceramides (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-12-31
    Description: Natural killer T (NKT) lymphocytes express an invariant T cell antigen receptor (TCR) encoded by the Valpha14 and Jalpha281 gene segments. A glycosylceramide-containing alpha-anomeric sugar with a longer fatty acyl chain (C26) and sphingosine base (C18) was identified as a ligand for this TCR. Glycosylceramide-mediated proliferative responses of Valpha14 NKT cells were abrogated by treatment with chloroquine-concanamycin A or by monoclonal antibodies against CD1d/Vbeta8, CD40/CD40L, or B7/CTLA-4/CD28, but not by interference with the function of a transporter-associated protein. Thus, this lymphocyte shares distinct recognition systems with either T or NK cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawano, T -- Cui, J -- Koezuka, Y -- Toura, I -- Kaneko, Y -- Motoki, K -- Ueno, H -- Nakagawa, R -- Sato, H -- Kondo, E -- Koseki, H -- Taniguchi, M -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1626-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CREST (Core Research for Evolutional Science and Technology) Project, Japan Science and Technology Corporation (JST), 1-8-1 Inohana, Chuo, Chiba 260, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9374463" target="_blank"〉PubMed〈/a〉

    CCR3 is a target for age-related macular degeneration diagnosis and therapy (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-06-16
    Description: Age-related macular degeneration (AMD), a leading cause of blindness worldwide, is as prevalent as cancer in industrialized nations. Most blindness in AMD results from invasion of the retina by choroidal neovascularisation (CNV). Here we show that the eosinophil/mast cell chemokine receptor CCR3 is specifically expressed in choroidal neovascular endothelial cells in humans with AMD, and that despite the expression of its ligands eotaxin-1, -2 and -3, neither eosinophils nor mast cells are present in human CNV. Genetic or pharmacological targeting of CCR3 or eotaxins inhibited injury-induced CNV in mice. CNV suppression by CCR3 blockade was due to direct inhibition of endothelial cell proliferation, and was uncoupled from inflammation because it occurred in mice lacking eosinophils or mast cells, and was independent of macrophage and neutrophil recruitment. CCR3 blockade was more effective at reducing CNV than vascular endothelial growth factor A (VEGF-A) neutralization, which is in clinical use at present, and, unlike VEGF-A blockade, is not toxic to the mouse retina. In vivo imaging with CCR3-targeting quantum dots located spontaneous CNV invisible to standard fluorescein angiography in mice before retinal invasion. CCR3 targeting might reduce vision loss due to AMD through early detection and therapeutic angioinhibition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2712122/" 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/PMC2712122/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takeda, Atsunobu -- Baffi, Judit Z -- Kleinman, Mark E -- Cho, Won Gil -- Nozaki, Miho -- Yamada, Kiyoshi -- Kaneko, Hiroki -- Albuquerque, Romulo J C -- Dridi, Sami -- Saito, Kuniharu -- Raisler, Brian J -- Budd, Steven J -- Geisen, Pete -- Munitz, Ariel -- Ambati, Balamurali K -- Green, Martha G -- Ishibashi, Tatsuro -- Wright, John D -- Humbles, Alison A -- Gerard, Craig J -- Ogura, Yuichiro -- Pan, Yuzhen -- Smith, Justine R -- Grisanti, Salvatore -- Hartnett, M Elizabeth -- Rothenberg, Marc E -- Ambati, Jayakrishna -- AI039759/AI/NIAID NIH HHS/ -- AI45898/AI/NIAID NIH HHS/ -- DK076893/DK/NIDDK NIH HHS/ -- EY010572/EY/NEI NIH HHS/ -- EY015130/EY/NEI NIH HHS/ -- EY015422/EY/NEI NIH HHS/ -- EY017011/EY/NEI NIH HHS/ -- EY017182/EY/NEI NIH HHS/ -- EY017950/EY/NEI NIH HHS/ -- EY018350/EY/NEI NIH HHS/ -- EY018836/EY/NEI NIH HHS/ -- R01 DK076893/DK/NIDDK NIH HHS/ -- R01 EY015422/EY/NEI NIH HHS/ -- R01 EY015422-04/EY/NEI NIH HHS/ -- R01 EY018350/EY/NEI NIH HHS/ -- R01 EY018350-02/EY/NEI NIH HHS/ -- R01 EY018836/EY/NEI NIH HHS/ -- R01 EY018836-02/EY/NEI NIH HHS/ -- England -- Nature. 2009 Jul 9;460(7252):225-30. doi: 10.1038/nature08151.

    Regulation of pancreatic beta cell mass by neuronal signals from the liver (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-11-22
    Description: Metabolic regulation in mammals requires communication between multiple organs and tissues. The rise in the incidence of obesity and associated metabolic disorders, including type 2 diabetes, has renewed interest in interorgan communication. We used mouse models to explore the mechanism whereby obesity enhances pancreatic beta cell mass, pathophysiological compensation for insulin resistance. We found that hepatic activation of extracellular regulated kinase (ERK) signaling induced pancreatic beta cell proliferation through a neuronal-mediated relay of metabolic signals. This metabolic relay from the liver to the pancreas is involved in obesity-induced islet expansion. In mouse models of insulin-deficient diabetes, liver-selective activation of ERK signaling increased beta cell mass and normalized serum glucose levels. Thus, interorgan metabolic relay systems may serve as valuable targets in regenerative treatments for diabetes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Imai, Junta -- Katagiri, Hideki -- Yamada, Tetsuya -- Ishigaki, Yasushi -- Suzuki, Toshinobu -- Kudo, Hirohito -- Uno, Kenji -- Hasegawa, Yutaka -- Gao, Junhong -- Kaneko, Keizo -- Ishihara, Hisamitsu -- Niijima, Akira -- Nakazato, Masamitsu -- Asano, Tomoichiro -- Minokoshi, Yasuhiko -- Oka, Yoshitomo -- New York, N.Y. -- Science. 2008 Nov 21;322(5905):1250-4. doi: 10.1126/science.1163971.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Metabolism and Diabetes, Tohoku University Graduate School of Medicine, Sendai 980-8575, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19023081" target="_blank"〉PubMed〈/a〉

    Anti-inflammatory activity of immunoglobulin G resulting from Fc sialylation (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-05
    Description: Immunoglobulin G (IgG) mediates pro- and anti-inflammatory activities through the engagement of its Fc fragment (Fc) with distinct Fcg receptors (FcgRs). One class of Fc-FcgR interactions generates pro-inflammatory effects of immune complexes and cytotoxic antibodies. In contrast, therapeutic intravenous gamma globulin and its Fc fragments are anti-inflammatory. We show here that these distinct properties of the IgG Fc result from differential sialylation of the Fc core polysaccharide. IgG acquires anti-inflammatory properties upon Fc sialylation, which is reduced upon the induction of an antigen-specific immune response. This differential sialylation may provide a switch from innate anti-inflammatory activity in the steady state to generating adaptive pro-inflammatory effects upon antigenic challenge.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaneko, Yoshikatsu -- Nimmerjahn, Falk -- Ravetch, Jeffrey V -- New York, N.Y. -- Science. 2006 Aug 4;313(5787):670-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Genetics and Immunology, Rockefeller University, 1230 York Avenue, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16888140" target="_blank"〉PubMed〈/a〉

    Neuronal pathway from the liver modulates energy expenditure and systemic insulin sensitivity (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-17
    Description: Coordinated control of energy metabolism and glucose homeostasis requires communication between organs and tissues. We identified a neuronal pathway that participates in the cross talk between the liver and adipose tissue. By studying a mouse model, we showed that adenovirus-mediated expression of peroxisome proliferator-activated receptor (PPAR)-g2 in the liver induces acute hepatic steatosis while markedly decreasing peripheral adiposity. These changes were accompanied by increased energy expenditure and improved systemic insulin sensitivity. Hepatic vagotomy and selective afferent blockage of the hepatic vagus revealed that the effects on peripheral tissues involve the afferent vagal nerve. Furthermore, an antidiabetic thiazolidinedione, a PPARg agonist, enhanced this pathway. This neuronal pathway from the liver may function to protect against metabolic perturbation induced by excessive energy storage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Uno, Kenji -- Katagiri, Hideki -- Yamada, Tetsuya -- Ishigaki, Yasushi -- Ogihara, Takehide -- Imai, Junta -- Hasegawa, Yutaka -- Gao, Junhong -- Kaneko, Keizo -- Iwasaki, Hiroko -- Ishihara, Hisamitsu -- Sasano, Hironobu -- Inukai, Kouichi -- Mizuguchi, Hiroyuki -- Asano, Tomoichiro -- Shiota, Masakazu -- Nakazato, Masamitsu -- Oka, Yoshitomo -- New York, N.Y. -- Science. 2006 Jun 16;312(5780):1656-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Metabolism and Diabetes, Tohoku University Graduate School of Medicine, Sendai 980-8575, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16778057" target="_blank"〉PubMed〈/a〉
