    Differential antigen processing by dendritic cell subsets in vivo (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-01-06
    Description: Dendritic cells (DCs) process and present self and foreign antigens to induce tolerance or immunity. In vitro models suggest that induction of immunity is controlled by regulating the presentation of antigen, but little is known about how DCs control antigen presentation in vivo. To examine antigen processing and presentation in vivo, we specifically targeted antigens to two major subsets of DCs by using chimeric monoclonal antibodies. Unlike CD8+ DCs that express the cell surface protein CD205, CD8- DCs, which are positive for the 33D1 antigen, are specialized for presentation on major histocompatibility complex (MHC) class II. This difference in antigen processing is intrinsic to the DC subsets and is associated with increased expression of proteins involved in MHC processing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dudziak, Diana -- Kamphorst, Alice O -- Heidkamp, Gordon F -- Buchholz, Veit R -- Trumpfheller, Christine -- Yamazaki, Sayuri -- Cheong, Cheolho -- Liu, Kang -- Lee, Han-Woong -- Park, Chae Gyu -- Steinman, Ralph M -- Nussenzweig, Michel C -- New York, N.Y. -- Science. 2007 Jan 5;315(5808):107-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Immunology, The Rockefeller University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17204652" target="_blank"〉PubMed〈/a〉

    Disparate individual fates compose robust CD8+ T cell immunity (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-03-16
    Description: A core feature of protective T cell responses to infection is the robust expansion and diversification of naive antigen-specific T cell populations into short-lived effector and long-lived memory subsets. By means of in vivo fate mapping, we found a striking variability of immune responses derived from individual CD8(+) T cells and show that robust acute and recall immunity requires the initial recruitment of multiple precursors. Unbiased mathematical modeling identifies the random integration of multiple differentiation and division events as the driving force behind this variability. Within this probabilistic framework, cell fate is specified along a linear developmental path that progresses from slowly proliferating long-lived to rapidly expanding short-lived subsets. These data provide insights into how complex biological systems implement stochastic processes to guarantee robust outcomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buchholz, Veit R -- Flossdorf, Michael -- Hensel, Inge -- Kretschmer, Lorenz -- Weissbrich, Bianca -- Graf, Patricia -- Verschoor, Admar -- Schiemann, Matthias -- Hofer, Thomas -- Busch, Dirk H -- New York, N.Y. -- Science. 2013 May 3;340(6132):630-5. doi: 10.1126/science.1235454.
