    Beschreibung: Although microbes have been classically viewed as pathogens, it is now well established that the majority of host-bacterial interactions are symbiotic. During development and into adulthood, gut bacteria shape the tissues, cells, and molecular profile of our gastrointestinal immune system. This partnership, forged over many millennia of coevolution, is based on a molecular exchange involving bacterial signals that are recognized by host receptors to mediate beneficial outcomes for both microbes and humans. We explore how specific aspects of the adaptive immune system are influenced by intestinal commensal bacteria. Understanding the molecular mechanisms that mediate symbiosis between commensal bacteria and humans may redefine how we view the evolution of adaptive immunity and consequently how we approach the treatment of numerous immunologic disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3159383/" 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/PMC3159383/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Yun Kyung -- Mazmanian, Sarkis K -- AI088626/AI/NIAID NIH HHS/ -- DK078938/DK/NIDDK NIH HHS/ -- DK083633/DK/NIDDK NIH HHS/ -- R01 DK078938/DK/NIDDK NIH HHS/ -- R01 DK078938-01A2/DK/NIDDK NIH HHS/ -- R01 DK078938-02/DK/NIDDK NIH HHS/ -- R01 DK078938-03/DK/NIDDK NIH HHS/ -- R01 DK078938-04/DK/NIDDK NIH HHS/ -- R21 AI088626/AI/NIAID NIH HHS/ -- R21 AI088626-01/AI/NIAID NIH HHS/ -- R21 AI088626-02/AI/NIAID NIH HHS/ -- R21 DK083633/DK/NIDDK NIH HHS/ -- R21 DK083633-01A1/DK/NIDDK NIH HHS/ -- R21 DK083633-02/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 24;330(6012):1768-73. doi: 10.1126/science.1195568.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21205662" target="_blank"〉PubMed〈/a〉

    Beschreibung: The interrelationships between our diets and the structure and operations of our gut microbial communities are poorly understood. A model community of 10 sequenced human gut bacteria was introduced into gnotobiotic mice, and changes in species abundance and microbial gene expression were measured in response to randomized perturbations of four defined ingredients in the host diet. From the responses, we developed a statistical model that predicted over 60% of the variation in species abundance evoked by diet perturbations, and we were able to identify which factors in the diet best explained changes seen for each community member. The approach is generally applicable, as shown by a follow-up study involving diets containing various mixtures of pureed human baby foods.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3303606/" 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/PMC3303606/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faith, Jeremiah J -- McNulty, Nathan P -- Rey, Federico E -- Gordon, Jeffrey I -- DK30292/DK/NIDDK NIH HHS/ -- DK70977/DK/NIDDK NIH HHS/ -- R01 DK070977/DK/NIDDK NIH HHS/ -- R01 DK070977-08/DK/NIDDK NIH HHS/ -- R37 DK030292/DK/NIDDK NIH HHS/ -- R37 DK030292-31/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2011 Jul 1;333(6038):101-4. doi: 10.1126/science.1206025.

    Beschreibung: Intestinal epithelial stem cell identity and location have been the subject of substantial research. Cells in the +4 niche are slow-cycling and label-retaining, whereas a different stem cell niche located at the crypt base is occupied by crypt base columnar (CBC) cells. CBCs are distinct from +4 cells, and the relationship between them is unknown, though both give rise to all intestinal epithelial lineages. We demonstrate that Hopx, an atypical homeobox protein, is a specific marker of +4 cells. Hopx-expressing cells give rise to CBCs and all mature intestinal epithelial lineages. Conversely, CBCs can give rise to +4 Hopx-positive cells. These findings demonstrate a bidirectional lineage relationship between active and quiescent stem cells in their niches.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3705713/" 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/PMC3705713/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takeda, Norifumi -- Jain, Rajan -- LeBoeuf, Matthew R -- Wang, Qiaohong -- Lu, Min Min -- Epstein, Jonathan A -- R01 HL071546/HL/NHLBI NIH HHS/ -- U01 HL100405/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2011 Dec 9;334(6061):1420-4. doi: 10.1126/science.1213214.

    Beschreibung: Spatial representation is an active process that requires complex multimodal integration from a large interacting network of cortical and subcortical structures. We sought to determine the role of cerebellar protein kinase C (PKC)-dependent plasticity in spatial navigation by recording the activity of hippocampal place cells in transgenic L7PKCI mice with selective disruption of PKC-dependent plasticity at parallel fiber-Purkinje cell synapses. Place cell properties were exclusively impaired when L7PKCI mice had to rely on self-motion cues. The behavioral consequence of such a deficit is evidenced here by selectively impaired navigation capabilities during a path integration task. Together, these results suggest that cerebellar PKC-dependent mechanisms are involved in processing self-motion signals essential to the shaping of hippocampal spatial representation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rochefort, Christelle -- Arabo, Arnaud -- Andre, Marion -- Poucet, Bruno -- Save, Etienne -- Rondi-Reig, Laure -- New York, N.Y. -- Science. 2011 Oct 21;334(6054):385-9. doi: 10.1126/science.1207403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurobiologie des Processus Adaptatifs (UMR 7102), Navigation, Memory, and Aging (ENMVI) Team, Universite Pierre et Marie Curie-Centre National de la Recherche Scientifique (CNRS), F-75005 Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22021859" target="_blank"〉PubMed〈/a〉
