    IFN-{alpha} and CD46 stimulation are associated with active lupus and skew natural T regulatory cell differentiation to type 1 regulatory T (Tr1) cells [Immunology] (2011)
    National Academy of Sciences
    Details
    Publication Date: 2011-11-23
    Description: Immune suppressive activities exerted by regulatory T-cell subsets have several specific functions, including self-tolerance and regulation of adaptive immune reactions, and their dysfunction can lead to autoimmune diseases and contribute to AIDS and cancer. Two functionally distinct regulatory T-cell subsets are currently identified in peripheral tissues: thymus-developed natural T regulatory cells (nTregs) controlling self-tolerance and antiinflammatory IL-10–secreting type 1 regulatory T cells (Tr1) derived from Ag-stimulated T cells, which regulate inflammation-dependent adaptive immunity and minimize immunopathology. We establish herein that cell contact-mediated nTreg regulatory function is inhibited by inflammation, especially in the presence of the complement C3b receptor (CD46). Instead, as with other T-cell subsets, the latter inflammatory conditions of stimulation skew nTreg differentiation to Tr1 cells secreting IL-10, an effect potentiated by IFN-α. The clinical relevance of these findings was verified in a study of 152 lupus patients, in which we showed that lupus nTreg dysfunction is not due to intrinsic defects but is rather induced by C3b stimulation of CD46 and IFN-α and that these immune components of inflammation are directly associated with active lupus. These results provide a rationale for using anti–IFN-α Ab immunotherapy in lupus patients.

    A partial pelvis of Australopithecus sediba (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-09-10
    Description: The fossil record of the hominin pelvis reflects important evolutionary changes in locomotion and parturition. The partial pelves of two individuals of Australopithecus sediba were reconstructed from previously reported finds and new material. These remains share some features with australopiths, such as large biacetabular diameter, small sacral and coxal joints, and long pubic rami. The specimens also share derived features with Homo, including more vertically oriented and sigmoid-shaped iliac blades, greater robusticity of the iliac body, sinusoidal anterior iliac borders, shortened ischia, and more superiorly oriented pubic rami. These derived features appear in a species with a small adult brain size, suggesting that the birthing of larger-brained babies was not driving the evolution of the pelvis at this time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kibii, Job M -- Churchill, Steven E -- Schmid, Peter -- Carlson, Kristian J -- Reed, Nichelle D -- de Ruiter, Darryl J -- Berger, Lee R -- New York, N.Y. -- Science. 2011 Sep 9;333(6048):1407-11. doi: 10.1126/science.1202521.

    Australopithecus sediba hand demonstrates mosaic evolution of locomotor and manipulative abilities (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-09-10
    Description: Hand bones from a single individual with a clear taxonomic affiliation are scarce in the hominin fossil record, which has hampered understanding the evolution of manipulative abilities in hominins. Here we describe and analyze a nearly complete wrist and hand of an adult female [Malapa Hominin 2 (MH2)] Australopithecus sediba from Malapa, South Africa (1.977 million years ago). The hand presents a suite of Australopithecus-like features, such as a strong flexor apparatus associated with arboreal locomotion, and Homo-like features, such as a long thumb and short fingers associated with precision gripping and possibly stone tool production. Comparisons to other fossil hominins suggest that there were at least two distinct hand morphotypes around the Plio-Pleistocene transition. The MH2 fossils suggest that Au. sediba may represent a basal condition associated with early stone tool use and production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kivell, Tracy L -- Kibii, Job M -- Churchill, Steven E -- Schmid, Peter -- Berger, Lee R -- New York, N.Y. -- Science. 2011 Sep 9;333(6048):1411-7. doi: 10.1126/science.1202625.

    Inclusive fitness theory and eusociality (2011)
    Nature Publishing Group (NPG)

    Publication Date: 2011-03-25
    Description: Arising from M. A. Nowak, C. E. Tarnita & E. O. Wilson 466, 1057-1062 (2010); Nowak et al. reply. Nowak et al. argue that inclusive fitness theory has been of little value in explaining the natural world, and that it has led to negligible progress in explaining the evolution of eusociality. However, we believe that their arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature. We will focus our comments on three general issues.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836173/" 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/PMC3836173/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abbot, Patrick -- Abe, Jun -- Alcock, John -- Alizon, Samuel -- Alpedrinha, Joao A C -- Andersson, Malte -- Andre, Jean-Baptiste -- van Baalen, Minus -- Balloux, Francois -- Balshine, Sigal -- Barton, Nick -- Beukeboom, Leo W -- Biernaskie, Jay M -- Bilde, Trine -- Borgia, Gerald -- Breed, Michael -- Brown, Sam -- Bshary, Redouan -- Buckling, Angus -- Burley, Nancy T -- Burton-Chellew, Max N -- Cant, Michael A -- Chapuisat, Michel -- Charnov, Eric L -- Clutton-Brock, Tim -- Cockburn, Andrew -- Cole, Blaine J -- Colegrave, Nick -- Cosmides, Leda -- Couzin, Iain D -- Coyne, Jerry A -- Creel, Scott -- Crespi, Bernard -- Curry, Robert L -- Dall, Sasha R X -- Day, Troy -- Dickinson, Janis L -- Dugatkin, Lee Alan -- El Mouden, Claire -- Emlen, Stephen T -- Evans, Jay -- Ferriere, Regis -- Field, Jeremy -- Foitzik, Susanne -- Foster, Kevin -- Foster, William A -- Fox, Charles W -- Gadau, Juergen -- Gandon, Sylvain -- Gardner, Andy -- Gardner, Michael G -- Getty, Thomas -- Goodisman, Michael A D -- Grafen, Alan -- Grosberg, Rick -- Grozinger, Christina M -- Gouyon, Pierre-Henri -- Gwynne, Darryl -- Harvey, Paul H -- Hatchwell, Ben J -- Heinze, Jurgen -- Helantera, Heikki -- Helms, Ken R -- Hill, Kim -- Jiricny, Natalie -- Johnstone, Rufus A -- Kacelnik, Alex -- Kiers, E Toby -- Kokko, Hanna -- Komdeur, Jan -- Korb, Judith -- Kronauer, Daniel -- Kummerli, Rolf -- Lehmann, Laurent -- Linksvayer, Timothy A -- Lion, Sebastien -- Lyon, Bruce -- Marshall, James A R -- McElreath, Richard -- Michalakis, Yannis -- Michod, Richard E -- Mock, Douglas -- Monnin, Thibaud -- Montgomerie, Robert -- Moore, Allen J -- Mueller, Ulrich G -- Noe, Ronald -- Okasha, Samir -- Pamilo, Pekka -- Parker, Geoff A -- Pedersen, Jes S -- Pen, Ido -- Pfennig, David -- Queller, David C -- Rankin, Daniel J -- Reece, Sarah E -- Reeve, Hudson K -- Reuter, Max -- Roberts, Gilbert -- Robson, Simon K A -- Roze, Denis -- Rousset, Francois -- Rueppell, Olav -- Sachs, Joel L -- Santorelli, Lorenzo -- Schmid-Hempel, Paul -- Schwarz, Michael P -- Scott-Phillips, Tom -- Shellmann-Sherman, Janet -- Sherman, Paul W -- Shuker, David M -- Smith, Jeff -- Spagna, Joseph C -- Strassmann, Beverly -- Suarez, Andrew V -- Sundstrom, Liselotte -- Taborsky, Michael -- Taylor, Peter -- Thompson, Graham -- Tooby, John -- Tsutsui, Neil D -- Tsuji, Kazuki -- Turillazzi, Stefano -- Ubeda, Francisco -- Vargo, Edward L -- Voelkl, Bernard -- Wenseleers, Tom -- West, Stuart A -- West-Eberhard, Mary Jane -- Westneat, David F -- Wiernasz, Diane C -- Wild, Geoff -- Wrangham, Richard -- Young, Andrew J -- Zeh, David W -- Zeh, Jeanne A -- Zink, Andrew -- BB/H022716/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2011 Mar 24;471(7339):E1-4; author reply E9-10. doi: 10.1038/nature09831.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21430721" target="_blank"〉PubMed〈/a〉

    Observed increase in local cooling effect of deforestation at higher latitudes (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-11-19
    Description: Deforestation in mid- to high latitudes is hypothesized to have the potential to cool the Earth's surface by altering biophysical processes. In climate models of continental-scale land clearing, the cooling is triggered by increases in surface albedo and is reinforced by a land albedo-sea ice feedback. This feedback is crucial in the model predictions; without it other biophysical processes may overwhelm the albedo effect to generate warming instead. Ongoing land-use activities, such as land management for climate mitigation, are occurring at local scales (hectares) presumably too small to generate the feedback, and it is not known whether the intrinsic biophysical mechanism on its own can change the surface temperature in a consistent manner. Nor has the effect of deforestation on climate been demonstrated over large areas from direct observations. Here we show that surface air temperature is lower in open land than in nearby forested land. The effect is 0.85 +/- 0.44 K (mean +/- one standard deviation) northwards of 45 degrees N and 0.21 +/- 0.53 K southwards. Below 35 degrees N there is weak evidence that deforestation leads to warming. Results are based on comparisons of temperature at forested eddy covariance towers in the USA and Canada and, as a proxy for small areas of cleared land, nearby surface weather stations. Night-time temperature changes unrelated to changes in surface albedo are an important contributor to the overall cooling effect. The observed latitudinal dependence is consistent with theoretical expectation of changes in energy loss from convection and radiation across latitudes in both the daytime and night-time phase of the diurnal cycle, the latter of which remains uncertain in climate models.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Xuhui -- Goulden, Michael L -- Hollinger, David Y -- Barr, Alan -- Black, T Andrew -- Bohrer, Gil -- Bracho, Rosvel -- Drake, Bert -- Goldstein, Allen -- Gu, Lianhong -- Katul, Gabriel -- Kolb, Thomas -- Law, Beverly E -- Margolis, Hank -- Meyers, Tilden -- Monson, Russell -- Munger, William -- Oren, Ram -- Paw U, Kyaw Tha -- Richardson, Andrew D -- Schmid, Hans Peter -- Staebler, Ralf -- Wofsy, Steven -- Zhao, Lei -- England -- Nature. 2011 Nov 16;479(7373):384-7. doi: 10.1038/nature10588.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Forestry and Environmental Studies, Yale University, New Haven, Connecticut 06511, USA. xuhui.lee@yale.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22094699" target="_blank"〉PubMed〈/a〉

    Increase in forest water-use efficiency as atmospheric carbon dioxide concentrations rise (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-07-12
    Description: Terrestrial plants remove CO2 from the atmosphere through photosynthesis, a process that is accompanied by the loss of water vapour from leaves. The ratio of water loss to carbon gain, or water-use efficiency, is a key characteristic of ecosystem function that is central to the global cycles of water, energy and carbon. Here we analyse direct, long-term measurements of whole-ecosystem carbon and water exchange. We find a substantial increase in water-use efficiency in temperate and boreal forests of the Northern Hemisphere over the past two decades. We systematically assess various competing hypotheses to explain this trend, and find that the observed increase is most consistent with a strong CO2 fertilization effect. The results suggest a partial closure of stomata-small pores on the leaf surface that regulate gas exchange-to maintain a near-constant concentration of CO2 inside the leaf even under continually increasing atmospheric CO2 levels. The observed increase in forest water-use efficiency is larger than that predicted by existing theory and 13 terrestrial biosphere models. The increase is associated with trends of increasing ecosystem-level photosynthesis and net carbon uptake, and decreasing evapotranspiration. Our findings suggest a shift in the carbon- and water-based economics of terrestrial vegetation, which may require a reassessment of the role of stomatal control in regulating interactions between forests and climate change, and a re-evaluation of coupled vegetation-climate models.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keenan, Trevor F -- Hollinger, David Y -- Bohrer, Gil -- Dragoni, Danilo -- Munger, J William -- Schmid, Hans Peter -- Richardson, Andrew D -- England -- Nature. 2013 Jul 18;499(7458):324-7. doi: 10.1038/nature12291.

    Australopithecus sediba: a new species of Homo-like australopith from South Africa (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-04-10
    Description: Despite a rich African Plio-Pleistocene hominin fossil record, the ancestry of Homo and its relation to earlier australopithecines remain unresolved. Here we report on two partial skeletons with an age of 1.95 to 1.78 million years. The fossils were encased in cave deposits at the Malapa site in South Africa. The skeletons were found close together and are directly associated with craniodental remains. Together they represent a new species of Australopithecus that is probably descended from Australopithecus africanus. Combined craniodental and postcranial evidence demonstrates that this new species shares more derived features with early Homo than any other australopith species and thus might help reveal the ancestor of that genus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berger, Lee R -- de Ruiter, Darryl J -- Churchill, Steven E -- Schmid, Peter -- Carlson, Kristian J -- Dirks, Paul H G M -- Kibii, Job M -- New York, N.Y. -- Science. 2010 Apr 9;328(5975):195-204. doi: 10.1126/science.1184944.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Human Evolution, University of the Witwatersrand, Private Bag 3, Wits 2050, South Africa. profleeberger@yahoo.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20378811" target="_blank"〉PubMed〈/a〉

    The upper limb of Australopithecus sediba (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-04-13
    Description: The evolution of the human upper limb involved a change in function from its use for both locomotion and prehension (as in apes) to a predominantly prehensile and manipulative role. Well-preserved forelimb remains of 1.98-million-year-old Australopithecus sediba from Malapa, South Africa, contribute to our understanding of this evolutionary transition. Whereas other aspects of their postcranial anatomy evince mosaic combinations of primitive (australopith-like) and derived (Homo-like) features, the upper limbs (excluding the hand and wrist) of the Malapa hominins are predominantly primitive and suggest the retention of substantial climbing and suspensory ability. The use of the forelimb primarily for prehension and manipulation appears to arise later, likely with the emergence of Homo erectus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Churchill, Steven E -- Holliday, Trenton W -- Carlson, Kristian J -- Jashashvili, Tea -- Macias, Marisa E -- Mathews, Sandra -- Sparling, Tawnee L -- Schmid, Peter -- de Ruiter, Darryl J -- Berger, Lee R -- New York, N.Y. -- Science. 2013 Apr 12;340(6129):1233477. doi: 10.1126/science.1233477.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Evolutionary Anthropology, Duke University, Durham, NC 27708, USA. churchy@duke.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23580536" target="_blank"〉PubMed〈/a〉
