    Induced pluripotent stem cells generated from patients with ALS can be differentiated into motor neurons (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-08-02
    Description: The generation of pluripotent stem cells from an individual patient would enable the large-scale production of the cell types affected by that patient's disease. These cells could in turn be used for disease modeling, drug discovery, and eventually autologous cell replacement therapies. Although recent studies have demonstrated the reprogramming of human fibroblasts to a pluripotent state, it remains unclear whether these induced pluripotent stem (iPS) cells can be produced directly from elderly patients with chronic disease. We have generated iPS cells from an 82-year-old woman diagnosed with a familial form of amyotrophic lateral sclerosis (ALS). These patient-specific iPS cells possess properties of embryonic stem cells and were successfully directed to differentiate into motor neurons, the cell type destroyed in ALS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dimos, John T -- Rodolfa, Kit T -- Niakan, Kathy K -- Weisenthal, Laurin M -- Mitsumoto, Hiroshi -- Chung, Wendy -- Croft, Gist F -- Saphier, Genevieve -- Leibel, Rudy -- Goland, Robin -- Wichterle, Hynek -- Henderson, Christopher E -- Eggan, Kevin -- New York, N.Y. -- Science. 2008 Aug 29;321(5893):1218-21. doi: 10.1126/science.1158799.

    Dysregulated humoral immunity to nontyphoidal Salmonella in HIV-infected African adults (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-04-24
    Description: Nontyphoidal Salmonellae are a major cause of life-threatening bacteremia among HIV-infected individuals. Although cell-mediated immunity controls intracellular infection, antibodies protect against Salmonella bacteremia. We report that high-titer antibodies specific for Salmonella lipopolysaccharide (LPS) are associated with a lack of Salmonella-killing in HIV-infected African adults. Killing was restored by genetically shortening LPS from the target Salmonella or removing LPS-specific antibodies from serum. Complement-mediated killing of Salmonella by healthy serum is shown to be induced specifically by antibodies against outer membrane proteins. This killing is lost when excess antibody against Salmonella LPS is added. Thus, our study indicates that impaired immunity against nontyphoidal Salmonella bacteremia in HIV infection results from excess inhibitory antibodies against Salmonella LPS, whereas serum killing of Salmonella is induced by antibodies against outer membrane proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3772309/" 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/PMC3772309/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacLennan, Calman A -- Gilchrist, James J -- Gordon, Melita A -- Cunningham, Adam F -- Cobbold, Mark -- Goodall, Margaret -- Kingsley, Robert A -- van Oosterhout, Joep J G -- Msefula, Chisomo L -- Mandala, Wilson L -- Leyton, Denisse L -- Marshall, Jennifer L -- Gondwe, Esther N -- Bobat, Saeeda -- Lopez-Macias, Constantino -- Doffinger, Rainer -- Henderson, Ian R -- Zijlstra, Eduard E -- Dougan, Gordon -- Drayson, Mark T -- MacLennan, Ian C M -- Molyneux, Malcolm E -- 067321/Wellcome Trust/United Kingdom -- BB/F022778/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0701275/Medical Research Council/United Kingdom -- G108/574/Medical Research Council/United Kingdom -- G8402371/Medical Research Council/United Kingdom -- G9818340/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Apr 23;328(5977):508-12. doi: 10.1126/science.1180346.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Centre for Immune Regulation and Clinical Immunology Service, Institute of Biomedical Research, School of Immunity and Infection, University of Birmingham, Birmingham, UK. c.maclennan@bham.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20413503" target="_blank"〉PubMed〈/a〉
