    Coinfection. Virus-helminth coinfection reveals a microbiota-independent mechanism of immunomodulation (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-08-02
    Description: The mammalian intestine is colonized by beneficial commensal bacteria and is a site of infection by pathogens, including helminth parasites. Helminths induce potent immunomodulatory effects, but whether these effects are mediated by direct regulation of host immunity or indirectly through eliciting changes in the microbiota is unknown. We tested this in the context of virus-helminth coinfection. Helminth coinfection resulted in impaired antiviral immunity and was associated with changes in the microbiota and STAT6-dependent helminth-induced alternative activation of macrophages. Notably, helminth-induced impairment of antiviral immunity was evident in germ-free mice, but neutralization of Ym1, a chitinase-like molecule that is associated with alternatively activated macrophages, could partially restore antiviral immunity. These data indicate that helminth-induced immunomodulation occurs independently of changes in the microbiota but is dependent on Ym1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4548887/" 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/PMC4548887/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Osborne, Lisa C -- Monticelli, Laurel A -- Nice, Timothy J -- Sutherland, Tara E -- Siracusa, Mark C -- Hepworth, Matthew R -- Tomov, Vesselin T -- Kobuley, Dmytro -- Tran, Sara V -- Bittinger, Kyle -- Bailey, Aubrey G -- Laughlin, Alice L -- Boucher, Jean-Luc -- Wherry, E John -- Bushman, Frederic D -- Allen, Judith E -- Virgin, Herbert W -- Artis, David -- 095831/Wellcome Trust/United Kingdom -- 2-P30 CA016520/CA/NCI NIH HHS/ -- 5T32A100716334/PHS HHS/ -- AI061570/AI/NIAID NIH HHS/ -- AI074878/AI/NIAID NIH HHS/ -- AI082630/AI/NIAID NIH HHS/ -- AI083022/AI/NIAID NIH HHS/ -- AI087990/AI/NIAID NIH HHS/ -- AI095466/AI/NIAID NIH HHS/ -- AI095608/AI/NIAID NIH HHS/ -- AI097333/AI/NIAID NIH HHS/ -- AI102942/AI/NIAID NIH HHS/ -- AI106697/AI/NIAID NIH HHS/ -- F32 AI085828/AI/NIAID NIH HHS/ -- F32-AI085828/AI/NIAID NIH HHS/ -- HHSN272201300006C/PHS HHS/ -- K08 DK097301/DK/NIDDK NIH HHS/ -- K08-DK097301/DK/NIDDK NIH HHS/ -- MR/J001929/1/Medical Research Council/United Kingdom -- P01 AI106697/AI/NIAID NIH HHS/ -- P30-AI045008/AI/NIAID NIH HHS/ -- P30-DK050306/DK/NIDDK NIH HHS/ -- R01 AI 084887/AI/NIAID NIH HHS/ -- R01 AI061570/AI/NIAID NIH HHS/ -- R01 AI074878/AI/NIAID NIH HHS/ -- R01 AI095466/AI/NIAID NIH HHS/ -- R01 AI097333/AI/NIAID NIH HHS/ -- R01 AI102942/AI/NIAID NIH HHS/ -- R21 AI087990/AI/NIAID NIH HHS/ -- T32-AI007532/AI/NIAID NIH HHS/ -- U01 AI095608/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Aug 1;345(6196):578-82. doi: 10.1126/science.1256942.

    Geriatric muscle stem cells switch reversible quiescence into senescence (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-02-14
    Description: Regeneration of skeletal muscle depends on a population of adult stem cells (satellite cells) that remain quiescent throughout life. Satellite cell regenerative functions decline with ageing. Here we report that geriatric satellite cells are incapable of maintaining their normal quiescent state in muscle homeostatic conditions, and that this irreversibly affects their intrinsic regenerative and self-renewal capacities. In geriatric mice, resting satellite cells lose reversible quiescence by switching to an irreversible pre-senescence state, caused by derepression of p16(INK4a) (also called Cdkn2a). On injury, these cells fail to activate and expand, undergoing accelerated entry into a full senescence state (geroconversion), even in a youthful environment. p16(INK4a) silencing in geriatric satellite cells restores quiescence and muscle regenerative functions. Our results demonstrate that maintenance of quiescence in adult life depends on the active repression of senescence pathways. As p16(INK4a) is dysregulated in human geriatric satellite cells, these findings provide the basis for stem-cell rejuvenation in sarcopenic muscles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sousa-Victor, Pedro -- Gutarra, Susana -- Garcia-Prat, Laura -- Rodriguez-Ubreva, Javier -- Ortet, Laura -- Ruiz-Bonilla, Vanessa -- Jardi, Merce -- Ballestar, Esteban -- Gonzalez, Susana -- Serrano, Antonio L -- Perdiguero, Eusebio -- Munoz-Canoves, Pura -- England -- Nature. 2014 Feb 20;506(7488):316-21. doi: 10.1038/nature13013.

    Pregnenolone can protect the brain from cannabis intoxication (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-01-05
    Description: Pregnenolone is considered the inactive precursor of all steroid hormones, and its potential functional effects have been largely uninvestigated. The administration of the main active principle of Cannabis sativa (marijuana), Delta(9)-tetrahydrocannabinol (THC), substantially increases the synthesis of pregnenolone in the brain via activation of the type-1 cannabinoid (CB1) receptor. Pregnenolone then, acting as a signaling-specific inhibitor of the CB1 receptor, reduces several effects of THC. This negative feedback mediated by pregnenolone reveals a previously unknown paracrine/autocrine loop protecting the brain from CB1 receptor overactivation that could open an unforeseen approach for the treatment of cannabis intoxication and addiction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4057431/" 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/PMC4057431/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vallee, Monique -- Vitiello, Sergio -- Bellocchio, Luigi -- Hebert-Chatelain, Etienne -- Monlezun, Stephanie -- Martin-Garcia, Elena -- Kasanetz, Fernando -- Baillie, Gemma L -- Panin, Francesca -- Cathala, Adeline -- Roullot-Lacarriere, Valerie -- Fabre, Sandy -- Hurst, Dow P -- Lynch, Diane L -- Shore, Derek M -- Deroche-Gamonet, Veronique -- Spampinato, Umberto -- Revest, Jean-Michel -- Maldonado, Rafael -- Reggio, Patricia H -- Ross, Ruth A -- Marsicano, Giovanni -- Piazza, Pier Vincenzo -- 260515/European Research Council/International -- DA-003934/DA/NIDA NIH HHS/ -- DA-03672/DA/NIDA NIH HHS/ -- DA-09789/DA/NIDA NIH HHS/ -- K05 DA021358/DA/NIDA NIH HHS/ -- R01 DA003934/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2014 Jan 3;343(6166):94-8. doi: 10.1126/science.1243985.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM, Neurocentre Magendie, Physiopathologie de la Plasticite Neuronale, U862, F-33000 Bordeaux, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24385629" target="_blank"〉PubMed〈/a〉

    Vascular and neurogenic rejuvenation of the aging mouse brain by young systemic factors (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-05-07
    Description: In the adult central nervous system, the vasculature of the neurogenic niche regulates neural stem cell behavior by providing circulating and secreted factors. Age-related decline of neurogenesis and cognitive function is associated with reduced blood flow and decreased numbers of neural stem cells. Therefore, restoring the functionality of the niche should counteract some of the negative effects of aging. We show that factors found in young blood induce vascular remodeling, culminating in increased neurogenesis and improved olfactory discrimination in aging mice. Further, we show that GDF11 alone can improve the cerebral vasculature and enhance neurogenesis. The identification of factors that slow the age-dependent deterioration of the neurogenic niche in mice may constitute the basis for new methods of treating age-related neurodegenerative and neurovascular diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4123747/" 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/PMC4123747/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Katsimpardi, Lida -- Litterman, Nadia K -- Schein, Pamela A -- Miller, Christine M -- Loffredo, Francesco S -- Wojtkiewicz, Gregory R -- Chen, John W -- Lee, Richard T -- Wagers, Amy J -- Rubin, Lee L -- 1DP2 OD004345/OD/NIH HHS/ -- 1R01 AG033053/AG/NIA NIH HHS/ -- 1R01 AG040019/AG/NIA NIH HHS/ -- 5U01 HL100402/HL/NHLBI NIH HHS/ -- DP2 OD004345/OD/NIH HHS/ -- R01 AG032977/AG/NIA NIH HHS/ -- R01 AG033053/AG/NIA NIH HHS/ -- R01 AG040019/AG/NIA NIH HHS/ -- R01 NS070835/NS/NINDS NIH HHS/ -- R01 NS072167/NS/NINDS NIH HHS/ -- R01NS070835/NS/NINDS NIH HHS/ -- R01NS072167/NS/NINDS NIH HHS/ -- U01 HL100402/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 May 9;344(6184):630-4. doi: 10.1126/science.1251141.

    mTOR- and HIF-1alpha-mediated aerobic glycolysis as metabolic basis for trained immunity (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-09-27
    Description: Epigenetic reprogramming of myeloid cells, also known as trained immunity, confers nonspecific protection from secondary infections. Using histone modification profiles of human monocytes trained with the Candida albicans cell wall constituent beta-glucan, together with a genome-wide transcriptome, we identified the induced expression of genes involved in glucose metabolism. Trained monocytes display high glucose consumption, high lactate production, and a high ratio of nicotinamide adenine dinucleotide (NAD(+)) to its reduced form (NADH), reflecting a shift in metabolism with an increase in glycolysis dependent on the activation of mammalian target of rapamycin (mTOR) through a dectin-1-Akt-HIF-1alpha (hypoxia-inducible factor-1alpha) pathway. Inhibition of Akt, mTOR, or HIF-1alpha blocked monocyte induction of trained immunity, whereas the adenosine monophosphate-activated protein kinase activator metformin inhibited the innate immune response to fungal infection. Mice with a myeloid cell-specific defect in HIF-1alpha were unable to mount trained immunity against bacterial sepsis. Our results indicate that induction of aerobic glycolysis through an Akt-mTOR-HIF-1alpha pathway represents the metabolic basis of trained immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4226238/" 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/PMC4226238/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cheng, Shih-Chin -- Quintin, Jessica -- Cramer, Robert A -- Shepardson, Kelly M -- Saeed, Sadia -- Kumar, Vinod -- Giamarellos-Bourboulis, Evangelos J -- Martens, Joost H A -- Rao, Nagesha Appukudige -- Aghajanirefah, Ali -- Manjeri, Ganesh R -- Li, Yang -- Ifrim, Daniela C -- Arts, Rob J W -- van der Veer, Brian M J W -- Deen, Peter M T -- Logie, Colin -- O'Neill, Luke A -- Willems, Peter -- van de Veerdonk, Frank L -- van der Meer, Jos W M -- Ng, Aylwin -- Joosten, Leo A B -- Wijmenga, Cisca -- Stunnenberg, Hendrik G -- Xavier, Ramnik J -- Netea, Mihai G -- 1P30GM106394-01/GM/NIGMS NIH HHS/ -- 5P30GM103415-03/GM/NIGMS NIH HHS/ -- DK097485/DK/NIDDK NIH HHS/ -- DK43351/DK/NIDDK NIH HHS/ -- P30 DK043351/DK/NIDDK NIH HHS/ -- P30 GM103415/GM/NIGMS NIH HHS/ -- P30 GM106394/GM/NIGMS NIH HHS/ -- R01 AI081838/AI/NIAID NIH HHS/ -- R01 DK097485/DK/NIDDK NIH HHS/ -- R01AI81838/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Sep 26;345(6204):1250684. doi: 10.1126/science.1250684.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Radboud University Medical Center, 6525 GA Nijmegen, Netherlands. ; Department of Microbiology and Immunology, Geisel School of Medicine at Dartmouth, Hanover, NH 03755, USA. ; Department of Molecular Biology, Faculties of Science and Medicine, Nijmegen Centre for Molecular Life Sciences, Radboud University, 6500 HB Nijmegen, Netherlands. ; Department of Genetics, University of Groningen, University Medical Center Groningen, Groningen, Netherlands. ; 4th Department of Internal Medicine, University of Athens Medical School, 12462 Athens, Greece. ; Department of Biochemistry, Faculties of Science and Medicine, Nijmegen Centre for Molecular Life Sciences, Radboud University, 6500 HB Nijmegen, Netherlands. ; Department of Physiology, Radboud University Medical Center, 6525 GA Nijmegen, Netherlands. ; School of Biochemistry and Immunology, Trinity Biomedical Sciences Institute, Trinity College Dublin, Dublin 2, Ireland. ; Center for Computational and Integrative Biology and Gastrointestinal Unit, Massachusetts General Hospital, Harvard School of Medicine, Boston, MA 02114, USA.

    Description: Throughout life, new neurons are continuously added to the dentate gyrus. As this continuous addition remodels hippocampal circuits, computational models predict that neurogenesis leads to degradation or forgetting of established memories. Consistent with this, increasing neurogenesis after the formation of a memory was sufficient to induce forgetting in adult mice. By contrast, during infancy, when hippocampal neurogenesis levels are high and freshly generated memories tend to be rapidly forgotten (infantile amnesia), decreasing neurogenesis after memory formation mitigated forgetting. In precocial species, including guinea pigs and degus, most granule cells are generated prenatally. Consistent with reduced levels of postnatal hippocampal neurogenesis, infant guinea pigs and degus did not exhibit forgetting. However, increasing neurogenesis after memory formation induced infantile amnesia in these species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akers, Katherine G -- Martinez-Canabal, Alonso -- Restivo, Leonardo -- Yiu, Adelaide P -- De Cristofaro, Antonietta -- Hsiang, Hwa-Lin Liz -- Wheeler, Anne L -- Guskjolen, Axel -- Niibori, Yosuke -- Shoji, Hirotaka -- Ohira, Koji -- Richards, Blake A -- Miyakawa, Tsuyoshi -- Josselyn, Sheena A -- Frankland, Paul W -- MOP74650/Canadian Institutes of Health Research/Canada -- MOP86762/Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2014 May 9;344(6184):598-602. doi: 10.1126/science.1248903.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Neurosciences and Mental Health, The Hospital for Sick Children, Toronto, M5G 1X8, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24812394" target="_blank"〉PubMed〈/a〉
