    Lymphoid tissue genesis induced by commensals through NOD1 regulates intestinal homeostasis (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-11-07
    Description: Intestinal homeostasis is critical for efficient energy extraction from food and protection from pathogens. Its disruption can lead to an array of severe illnesses with major impacts on public health, such as inflammatory bowel disease characterized by self-destructive intestinal immunity. However, the mechanisms regulating the equilibrium between the large bacterial flora and the immune system remain unclear. Intestinal lymphoid tissues generate flora-reactive IgA-producing B cells, and include Peyer's patches and mesenteric lymph nodes, as well as numerous isolated lymphoid follicles (ILFs). Here we show that peptidoglycan from Gram-negative bacteria is necessary and sufficient to induce the genesis of ILFs in mice through recognition by the NOD1 (nucleotide-binding oligomerization domain containing 1) innate receptor in epithelial cells, and beta-defensin 3- and CCL20-mediated signalling through the chemokine receptor CCR6. Maturation of ILFs into large B-cell clusters requires subsequent detection of bacteria by toll-like receptors. In the absence of ILFs, the composition of the intestinal bacterial community is profoundly altered. Our results demonstrate that intestinal bacterial commensals and the immune system communicate through an innate detection system to generate adaptive lymphoid tissues and maintain intestinal homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bouskra, Djahida -- Brezillon, Christophe -- Berard, Marion -- Werts, Catherine -- Varona, Rosa -- Boneca, Ivo Gomperts -- Eberl, Gerard -- England -- Nature. 2008 Nov 27;456(7221):507-10. doi: 10.1038/nature07450.

    The intestinal microbiota modulates the anticancer immune effects of cyclophosphamide (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-11-23
    Description: Cyclophosphamide is one of several clinically important cancer drugs whose therapeutic efficacy is due in part to their ability to stimulate antitumor immune responses. Studying mouse models, we demonstrate that cyclophosphamide alters the composition of microbiota in the small intestine and induces the translocation of selected species of Gram-positive bacteria into secondary lymphoid organs. There, these bacteria stimulate the generation of a specific subset of "pathogenic" T helper 17 (pT(H)17) cells and memory T(H)1 immune responses. Tumor-bearing mice that were germ-free or that had been treated with antibiotics to kill Gram-positive bacteria showed a reduction in pT(H)17 responses, and their tumors were resistant to cyclophosphamide. Adoptive transfer of pT(H)17 cells partially restored the antitumor efficacy of cyclophosphamide. These results suggest that the gut microbiota help shape the anticancer immune response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4048947/" 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/PMC4048947/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Viaud, Sophie -- Saccheri, Fabiana -- Mignot, Gregoire -- Yamazaki, Takahiro -- Daillere, Romain -- Hannani, Dalil -- Enot, David P -- Pfirschke, Christina -- Engblom, Camilla -- Pittet, Mikael J -- Schlitzer, Andreas -- Ginhoux, Florent -- Apetoh, Lionel -- Chachaty, Elisabeth -- Woerther, Paul-Louis -- Eberl, Gerard -- Berard, Marion -- Ecobichon, Chantal -- Clermont, Dominique -- Bizet, Chantal -- Gaboriau-Routhiau, Valerie -- Cerf-Bensussan, Nadine -- Opolon, Paule -- Yessaad, Nadia -- Vivier, Eric -- Ryffel, Bernhard -- Elson, Charles O -- Dore, Joel -- Kroemer, Guido -- Lepage, Patricia -- Boneca, Ivo Gomperts -- Ghiringhelli, Francois -- Zitvogel, Laurence -- P01 DK071176/DK/NIDDK NIH HHS/ -- P01DK071176/DK/NIDDK NIH HHS/ -- P50 CA086355/CA/NCI NIH HHS/ -- R01 AI084880/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Nov 22;342(6161):971-6. doi: 10.1126/science.1240537.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale, U1015, Equipe labellisee Ligue Nationale Contre le Cancer, Institut Gustave Roussy, Villejuif, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24264990" target="_blank"〉PubMed〈/a〉

    Anticancer immunotherapy by CTLA-4 blockade relies on the gut microbiota (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-11-07
    Description: Antibodies targeting CTLA-4 have been successfully used as cancer immunotherapy. We find that the antitumor effects of CTLA-4 blockade depend on distinct Bacteroides species. In mice and patients, T cell responses specific for B. thetaiotaomicron or B. fragilis were associated with the efficacy of CTLA-4 blockade. Tumors in antibiotic-treated or germ-free mice did not respond to CTLA blockade. This defect was overcome by gavage with B. fragilis, by immunization with B. fragilis polysaccharides, or by adoptive transfer of B. fragilis-specific T cells. Fecal microbial transplantation from humans to mice confirmed that treatment of melanoma patients with antibodies against CTLA-4 favored the outgrowth of B. fragilis with anticancer properties. This study reveals a key role for Bacteroidales in the immunostimulatory effects of CTLA-4 blockade.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4721659/" 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/PMC4721659/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vetizou, Marie -- Pitt, Jonathan M -- Daillere, Romain -- Lepage, Patricia -- Waldschmitt, Nadine -- Flament, Caroline -- Rusakiewicz, Sylvie -- Routy, Bertrand -- Roberti, Maria P -- Duong, Connie P M -- Poirier-Colame, Vichnou -- Roux, Antoine -- Becharef, Sonia -- Formenti, Silvia -- Golden, Encouse -- Cording, Sascha -- Eberl, Gerard -- Schlitzer, Andreas -- Ginhoux, Florent -- Mani, Sridhar -- Yamazaki, Takahiro -- Jacquelot, Nicolas -- Enot, David P -- Berard, Marion -- Nigou, Jerome -- Opolon, Paule -- Eggermont, Alexander -- Woerther, Paul-Louis -- Chachaty, Elisabeth -- Chaput, Nathalie -- Robert, Caroline -- Mateus, Christina -- Kroemer, Guido -- Raoult, Didier -- Boneca, Ivo Gomperts -- Carbonnel, Franck -- Chamaillard, Mathias -- Zitvogel, Laurence -- R01 CA161879/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Nov 27;350(6264):1079-84. doi: 10.1126/science.aad1329.

    Notes: Abstract Objective: The absorption kinetics of paracetamol is dependent on gastric emptying and its measurement was proposed as a non-invasive method to estimate gastric emptying rate. The objective of this study was to evaluate the intraindividual variability of paracetamol absorption kinetics after a semi-solid meal. Methods: The pharmacokinetics of paracetamol was studied on two occasions in 15 healthy volunteers without Helicobacter pylori antibodies. A 1-g dose of paracetamol was given as a solution together with a standardised semi-solid meal and the subjects stayed in the supine position. Results: For most of the subjects, the time course of paracetamol concentrations was similar on the two occasions. The intraindividual variability was low, with coefficients of variation of 38.3%, 8.0% and 3.8% for time to maximum plasma concentration, maximum concentration and area under the plasma concentration – time curve until 6 h, respectively. Conclusion: The assessment of paracetamol absorption kinetics is reproducible when the drug is given together with a semi-solid meal in Helicobacter pylori-negative healthy subjects.

    Notes: Abstract The dry abradability and diamond pyramid hardness of HfO2 fully-stabilized by variable additions of Er2O3 were determined on sintered polycrystalline specimens of near-theoretical densities. Measurements on fused silica and on a single crystal of Y2O3-stabilized ZrO2 were included for comparison. In general, the hardness was decreased and the abradability was increased by increasing additions of stabilizing oxide. These effects were attributed mainly to the increase in defect concentration of the anion sublattice with increasing amounts of modifier oxide. Solution of HfO2 in Er2O3 (rare-earth-oxide Type C structure) increased hardness and decreased abradability: effects which also seemed to be related to the defect concentration of the anion sublattice.

    Notes: Summary Culture medium conditioned with human hemangioma promotes the growth of endothelial cells from isolated adult porcine brain capillaries in primary culture and represents an improvement in culture conditions for such cells. It is the first enriched medium that is not supplied with purified growth factors or conditioned with cultured tumoral cells. Porcine brain microvascular endothelial cells grown in this manner display a typical capillary endothelial morphology, synthesize von Willebrand Factor, and express angiotensin converting enzyme activity.
