    Neutral metacommunity models predict fish diversity patterns in Mississippi-Missouri basin (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-05-10
    Description: River networks, seen as ecological corridors featuring connected and hierarchical dendritic landscapes for animals and plants, present unique challenges and opportunities for testing biogeographical theories and macroecological laws. Although local and basin-scale differences in riverine fish diversity have been analysed as functions of energy availability and habitat heterogeneity, scale-dependent environmental conditions and river discharge, a model that predicts a comprehensive set of system-wide diversity patterns has been hard to find. Here we show that fish diversity patterns throughout the Mississippi-Missouri River System are well described by a neutral metacommunity model coupled with an appropriate habitat capacity distribution and dispersal kernel. River network structure acts as an effective template for characterizing spatial attributes of fish biodiversity. We show that estimates of average dispersal behaviour and habitat capacities, objectively calculated from average runoff production, yield reliable predictions of large-scale spatial biodiversity patterns in riverine systems. The success of the neutral theory in two-dimensional forest ecosystems and here in dendritic riverine ecosystems suggests the possible application of neutral metacommunity models in a diverse suite of ecosystems. This framework offers direct linkage from large-scale forcing, such as global climate change, to biodiversity patterns.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Muneepeerakul, Rachata -- Bertuzzo, Enrico -- Lynch, Heather J -- Fagan, William F -- Rinaldo, Andrea -- Rodriguez-Iturbe, Ignacio -- England -- Nature. 2008 May 8;453(7192):220-2. doi: 10.1038/nature06813.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Civil and Environmental Engineering, E-Quad, Princeton University, Princeton, New Jersey 08544, USA. rmuneepe@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18464742" target="_blank"〉PubMed〈/a〉

    Disease-corrected haematopoietic progenitors from Fanconi anaemia induced pluripotent stem cells (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-06-02
    Description: The generation of induced pluripotent stem (iPS) cells has enabled the derivation of patient-specific pluripotent cells and provided valuable experimental platforms to model human disease. Patient-specific iPS cells are also thought to hold great therapeutic potential, although direct evidence for this is still lacking. Here we show that, on correction of the genetic defect, somatic cells from Fanconi anaemia patients can be reprogrammed to pluripotency to generate patient-specific iPS cells. These cell lines appear indistinguishable from human embryonic stem cells and iPS cells from healthy individuals. Most importantly, we show that corrected Fanconi-anaemia-specific iPS cells can give rise to haematopoietic progenitors of the myeloid and erythroid lineages that are phenotypically normal, that is, disease-free. These data offer proof-of-concept that iPS cell technology can be used for the generation of disease-corrected, patient-specific cells with potential value for cell therapy applications.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2720823/" 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/PMC2720823/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raya, Angel -- Rodriguez-Piza, Ignasi -- Guenechea, Guillermo -- Vassena, Rita -- Navarro, Susana -- Barrero, Maria Jose -- Consiglio, Antonella -- Castella, Maria -- Rio, Paula -- Sleep, Eduard -- Gonzalez, Federico -- Tiscornia, Gustavo -- Garreta, Elena -- Aasen, Trond -- Veiga, Anna -- Verma, Inder M -- Surralles, Jordi -- Bueren, Juan -- Izpisua Belmonte, Juan Carlos -- R01 HL053670/HL/NHLBI NIH HHS/ -- R01 HL053670-14/HL/NHLBI NIH HHS/ -- England -- Nature. 2009 Jul 2;460(7251):53-9. doi: 10.1038/nature08129.

    Formyl peptide receptor-like proteins are a novel family of vomeronasal chemosensors (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-04-24
    Description: Mammals rely heavily on olfaction to interact adequately with each other and with their environment. They make use of seven-transmembrane G-protein-coupled receptors to identify odorants and pheromones. These receptors are present on dendrites of olfactory sensory neurons located in the main olfactory or vomeronasal sensory epithelia, and pertain to the odorant, trace amine-associated receptor and vomeronasal type 1 (ref. 4) or 2 (refs 5-7) receptor superfamilies. Whether these four sensor classes represent the complete olfactory molecular repertoire used by mammals to make sense of the outside world is unknown. Here we report the expression of formyl peptide receptor-related genes by vomeronasal sensory neurons, in multiple mammalian species. Similar to the four known olfactory receptor gene classes, these genes encode seven-transmembrane proteins, and are characterized by monogenic transcription and a punctate expression pattern in the sensory neuroepithelium. In vitro expression of mouse formyl peptide receptor-like 1, 3, 4, 6 and 7 provides sensitivity to disease/inflammation-related ligands. Establishing an in situ approach that combines whole-mount vomeronasal preparations with dendritic calcium imaging in the intact neuroepithelium, we show neuronal responses to the same molecules, which therefore represent a new class of vomeronasal agonists. Taken together, these results suggest that formyl peptide receptor-like proteins have an olfactory function associated with the identification of pathogens, or of pathogenic states.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Riviere, Stephane -- Challet, Ludivine -- Fluegge, Daniela -- Spehr, Marc -- Rodriguez, Ivan -- England -- Nature. 2009 May 28;459(7246):574-7. doi: 10.1038/nature08029.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology and Animal Biology, and National Center of Competence Frontiers in Genetics, University of Geneva, 1205 Geneva, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19387439" target="_blank"〉PubMed〈/a〉
