    Description: We synthesized multimetal microrods intrinsically encoded with submicrometer stripes. Complex striping patterns are readily prepared by sequential electrochemical deposition of metal ions into templates with uniformly sized pores. The differential reflectivity of adjacent stripes enables identification of the striping patterns by conventional light microscopy. This readout mechanism does not interfere with the use of fluorescence for detection of analytes bound to particles by affinity capture, as demonstrated by DNA and protein bioassays.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nicewarner-Pena, S R -- Freeman, R G -- Reiss, B D -- He, L -- Pena, D J -- Walton, I D -- Cromer, R -- Keating, C D -- Natan, M J -- HG02228/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2001 Oct 5;294(5540):137-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Pennsylvania State University, 152 Davey Laboratory, University Park, PA 16802, USA., SurroMed Inc., 2375 Garcia Avenue, Mountain View, CA 94043, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11588257" target="_blank"〉PubMed〈/a〉

    Description: Myeloperoxidase (MPO) is an abundant mammalian phagocyte hemoprotein thought to primarily mediate host defense reactions. Although its microbicidal functions are well established in vitro, humans deficient in MPO are not at unusual risk of infection. MPO was observed herein to modulate the vascular signaling and vasodilatory functions of nitric oxide (NO) during acute inflammation. After leukocyte degranulation, MPO localized in and around vascular endothelial cells in a rodent model of acute endotoxemia and impaired endothelium-dependent relaxant responses, to which MPO-deficient mice were resistant. Altered vascular responsiveness was due to catalytic consumption of NO by substrate radicals generated by MPO. Thus MPO can directly modulate vascular inflammatory responses by regulating NO bioavailability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eiserich, Jason P -- Baldus, Stephan -- Brennan, Marie-Luise -- Ma, Wenxin -- Zhang, Chunxiang -- Tousson, Albert -- Castro, Laura -- Lusis, Aldons J -- Nauseef, William M -- White, C Roger -- Freeman, Bruce A -- I01 BX000513/BX/BLRD VA/ -- R01 HL067930/HL/NHLBI NIH HHS/ -- R03 TW005682/TW/FIC NIH HHS/ -- New York, N.Y. -- Science. 2002 Jun 28;296(5577):2391-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Division of Nephrology, University of California, Davis, CA 95616, USA. jpeiserich@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12089442" target="_blank"〉PubMed〈/a〉

    Description: The autosomal dominant hyper-IgE syndrome (HIES, 'Job's syndrome') is characterized by recurrent and often severe pulmonary infections, pneumatoceles, eczema, staphylococcal abscesses, mucocutaneous candidiasis, and abnormalities of bone and connective tissue. Mutations presumed to underlie HIES have recently been identified in stat3, the gene encoding STAT3 (signal transducer and activator of transcription 3) (refs 3, 4). Although impaired production of interferon-gamma and tumour-necrosis factor by T cells, diminished memory T-cell populations, decreased delayed-type-hypersensitivity responses and decreased in vitro lymphoproliferation in response to specific antigens have variably been described, specific immunological abnormalities that can explain the unique susceptibility to particular infections seen in HIES have not yet been defined. Here we show that interleukin (IL)-17 production by T cells is absent in HIES individuals. We observed that ex vivo T cells from subjects with HIES failed to produce IL-17, but not IL-2, tumour-necrosis factor or interferon-gamma, on mitogenic stimulation with staphylococcal enterotoxin B or on antigenic stimulation with Candida albicans or streptokinase. Purified naive T cells were unable to differentiate into IL-17-producing (T(H)17) T helper cells in vitro and had lower expression of retinoid-related orphan receptor (ROR)-gammat, which is consistent with a crucial role for STAT3 signalling in the generation of T(H)17 cells. T(H)17 cells have emerged as an important subset of helper T cells that are believed to be critical in the clearance of fungal and extracellular bacterial infections. Thus, our data suggest that the inability to produce T(H)17 cells is a mechanism underlying the susceptibility to the recurrent infections commonly seen in HIES.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2864108/" 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/PMC2864108/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Milner, Joshua D -- Brenchley, Jason M -- Laurence, Arian -- Freeman, Alexandra F -- Hill, Brenna J -- Elias, Kevin M -- Kanno, Yuka -- Spalding, Christine -- Elloumi, Houda Z -- Paulson, Michelle L -- Davis, Joie -- Hsu, Amy -- Asher, Ava I -- O'Shea, John -- Holland, Steven M -- Paul, William E -- Douek, Daniel C -- Z99 AI999999/Intramural NIH HHS/ -- England -- Nature. 2008 Apr 10;452(7188):773-6. doi: 10.1038/nature06764.

    Description: Science, technology, engineering, and mathematics instructors have been charged with improving the performance and retention of students from diverse backgrounds. To date, programs that close the achievement gap between students from disadvantaged versus nondisadvantaged educational backgrounds have required extensive extramural funding. We show that a highly structured course design, based on daily and weekly practice with problem-solving, data analysis, and other higher-order cognitive skills, improved the performance of all students in a college-level introductory biology class and reduced the achievement gap between disadvantaged and nondisadvantaged students--without increased expenditures. These results support the Carnegie Hall hypothesis: Intensive practice, via active-learning exercises, has a disproportionate benefit for capable but poorly prepared students.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haak, David C -- HilleRisLambers, Janneke -- Pitre, Emile -- Freeman, Scott -- 52003841/Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Jun 3;332(6034):1213-6. doi: 10.1126/science.1204820.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Box 351800, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21636776" target="_blank"〉PubMed〈/a〉

    Description: The cytokine tumor necrosis factor (TNF) is the primary trigger of inflammation. Like many extracellular signaling proteins, TNF is synthesized as a transmembrane protein; the active signal is its ectodomain, which is shed from cells after cleavage by an ADAM family metalloprotease, ADAM17 (TNFalpha-converting enzyme, TACE). We report that iRhom2 (RHBDF2), a proteolytically inactive member of the rhomboid family, is required for TNF release in mice. iRhom2 binds TACE and promotes its exit from the endoplasmic reticulum. The failure of TACE to exit the endoplasmic reticulum in the absence of iRhom2 prevents the furin-mediated maturation and trafficking of TACE to the cell surface, the site of TNF cleavage. Given the role of TNF in autoimmune and inflammatory diseases, iRhom2 may represent an attractive therapeutic target.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3272371/" 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/PMC3272371/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adrain, Colin -- Zettl, Markus -- Christova, Yonka -- Taylor, Neil -- Freeman, Matthew -- MC_U105178780/Medical Research Council/United Kingdom -- U.1051.01.009(78780)/Medical Research Council/United Kingdom -- U105178780/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Jan 13;335(6065):225-8. doi: 10.1126/science.1214400.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Laboratory of Molecular Biology, Hills Road, Cambridge CB2 0QH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22246777" target="_blank"〉PubMed〈/a〉

    Description: In the absence of costimulation, T cells activated through their antigen receptor become unresponsive (anergic) and do not transcribe the gene encoding interleukin-2 (IL-2) when restimulated with antigen. Anergic alloantigen-specific human T cells contained phosphorylated Cbl that coimmunoprecipitated with Fyn. The adapter protein CrkL was associated with both phosphorylated Cbl and the guanidine nucleotide-releasing factor C3G, which catalyzes guanosine triphosphate (GTP) exchange on Rap1. Active Rap1 (GTP-bound form) was present in anergic cells. Forced expression of low amounts of Rap1-GTP in Jurkat T cells recapitulated the anergic defect and blocked T cell antigen receptor (TCR)- and CD28-mediated IL-2 gene transcription. Therefore, Rap1 functions as a negative regulator of TCR-mediated IL-2 gene transcription and may be responsible for the specific defect in IL-2 production in T cell anergy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boussiotis, V A -- Freeman, G J -- Berezovskaya, A -- Barber, D L -- Nadler, L M -- AI 35225/AI/NIAID NIH HHS/ -- AI39671/AI/NIAID NIH HHS/ -- HL 54785/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1997 Oct 3;278(5335):124-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Adult Oncology, Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA 02115, USA. vassiliki_boussiotis@macmailgw.dfci.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9311917" target="_blank"〉PubMed〈/a〉
