    Requirement for RORgamma in thymocyte survival and lymphoid organ development (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-07-06
    Description: Most developing thymocytes undergo apoptosis because they cannot interact productively with molecules encoded by the major histocompatibility complex. Here, we show that mice lacking the orphan nuclear hormone receptor RORgamma lose thymic expression of the anti-apoptotic factor Bcl-xL. RORgamma thus regulates the survival of CD4+8+ thymocytes and may control the temporal window during which thymocytes can undergo positive selection. RORgamma was also required for development of lymph nodes and Peyer's patches, but not splenic follicles. In its absence, there was loss of a population of CD3-CD4+CD45+ cells that normally express RORgamma and that are likely early progenitors of lymphoid organs. Hence, RORgamma has critical functions in T cell repertoire selection and lymphoid organogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sun, Z -- Unutmaz, D -- Zou, Y R -- Sunshine, M J -- Pierani, A -- Brenner-Morton, S -- Mebius, R E -- Littman, D R -- New York, N.Y. -- Science. 2000 Jun 30;288(5475):2369-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Pathogenesis Program, Skirball Institute of Biomolecular Medicine and Howard Hughes Medical Institute, New York University School of Medicine, New York, NY 10016, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10875923" target="_blank"〉PubMed〈/a〉

    TGF-beta-induced Foxp3 inhibits T(H)17 cell differentiation by antagonizing RORgammat function (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-03-28
    Description: T helper cells that produce IL-17 (T(H)17 cells) promote autoimmunity in mice and have been implicated in the pathogenesis of human inflammatory diseases. At mucosal surfaces, T(H)17 cells are thought to protect the host from infection, whereas regulatory T (T(reg)) cells control immune responses and inflammation triggered by the resident microflora. Differentiation of both cell types requires transforming growth factor-beta (TGF-beta), but depends on distinct transcription factors: RORgammat (encoded by Rorc(gammat)) for T(H)17 cells and Foxp3 for T(reg) cells. How TGF-beta regulates the differentiation of T cells with opposing activities has been perplexing. Here we demonstrate that, together with pro-inflammatory cytokines, TGF-beta orchestrates T(H)17 cell differentiation in a concentration-dependent manner. At low concentrations, TGF-beta synergizes with interleukin (IL)-6 and IL-21 (refs 9-11) to promote IL-23 receptor (Il23r) expression, favouring T(H)17 cell differentiation. High concentrations of TGF-beta repress IL23r expression and favour Foxp3+ T(reg) cells. RORgammat and Foxp3 are co-expressed in naive CD4+ T cells exposed to TGF-beta and in a subset of T cells in the small intestinal lamina propria of the mouse. In vitro, TGF-beta-induced Foxp3 inhibits RORgammat function, at least in part through their interaction. Accordingly, lamina propria T cells that co-express both transcription factors produce less IL-17 (also known as IL-17a) than those that express RORgammat alone. IL-6, IL-21 and IL-23 relieve Foxp3-mediated inhibition of RORgammat, thereby promoting T(H)17 cell differentiation. Therefore, the decision of antigen-stimulated cells to differentiate into either T(H)17 or T(reg) cells depends on the cytokine-regulated balance of RORgammat and Foxp3.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2597437/" 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/PMC2597437/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Liang -- Lopes, Jared E -- Chong, Mark M W -- Ivanov, Ivaylo I -- Min, Roy -- Victora, Gabriel D -- Shen, Yuelei -- Du, Jianguang -- Rubtsov, Yuri P -- Rudensky, Alexander Y -- Ziegler, Steven F -- Littman, Dan R -- AI48779/AI/NIAID NIH HHS/ -- R01 AI048779/AI/NIAID NIH HHS/ -- R01 AI048779-05/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 May 8;453(7192):236-40. doi: 10.1038/nature06878.

    Thymic origin of intestinal alphabeta T cells revealed by fate mapping of RORgammat+ cells (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-07-13
    Description: Intestinal intraepithelial T lymphocytes (IELs) are likely to play a key role in host mucosal immunity and, unlike other T cells, have been proposed to differentiate from local precursors rather than from thymocytes. We show here that IELs expressing the alphabeta T cell receptor are derived from precursors that express RORgammat, an orphan nuclear hormone receptor detected only in immature CD4+CD8+ thymocytes, fetal lymphoid tissue-inducer (LTi) cells, and LTi-like cells in cryptopatches within the adult intestinal lamina propria. Using cell fate mapping, we found that all intestinal alphabeta T cells are progeny of CD4+CD8+ thymocytes, indicating that the adult intestine is not a significant site for alphabeta T cell development. Our results suggest that intestinal RORgammat+ cells are local organizers of mucosal lymphoid tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eberl, Gerard -- Littman, Dan R -- New York, N.Y. -- Science. 2004 Jul 9;305(5681):248-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Pathogenesis Program, Skirball Institute of Biomolecular Medicine, New York University School of Medicine, New York, NY 10016, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15247480" target="_blank"〉PubMed〈/a〉

    Helper T cells without CD4: control of leishmaniasis in CD4-deficient mice (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-09-10
    Description: Expression of either the CD4 or CD8 glycoproteins discriminates two functionally distinct lineages of T lymphocytes. A null mutation in the gene encoding CD4 impairs the development of the helper cell lineage that is normally defined by CD4 expression. Infection of CD4-null mice with Leishmania has revealed a population of functional helper T cells that develops despite the absence of CD4. These CD8- alpha beta T cell receptor+ T cells are major histocompatibility complex class II-restricted and produce interferon-gamma when challenged with parasite antigens. These results indicate that T lymphocyte lineage commitment and peripheral function need not depend on the function of CD4.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Locksley, R M -- Reiner, S L -- Hatam, F -- Littman, D R -- Killeen, N -- AI30663/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1993 Sep 10;261(5127):1448-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of California, San Francisco 94143-0654.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8367726" target="_blank"〉PubMed〈/a〉

    Nonredundant function of soluble LTalpha3 produced by innate lymphoid cells in intestinal homeostasis (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-12-07
    Description: Immunoglobulin A (IgA) production at mucosal surfaces contributes to protection against pathogens and controls intestinal microbiota composition. However, mechanisms regulating IgA induction are not completely defined. We show that soluble lymphotoxin alpha (sLTalpha3) produced by RORgammat(+) innate lymphoid cells (ILCs) controls T cell-dependent IgA induction in the lamina propria via regulation of T cell homing to the gut. By contrast, membrane-bound lymphotoxin beta (LTalpha1beta2) produced by RORgammat(+) ILCs is critical for T cell-independent IgA induction in the lamina propria via control of dendritic cell functions. Ablation of LTalpha in RORgammat(+) cells abrogated IgA production in the gut and altered microbiota composition. Thus, soluble and membrane-bound lymphotoxins produced by ILCs distinctly organize adaptive immune responses in the gut and control commensal microbiota composition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kruglov, Andrey A -- Grivennikov, Sergei I -- Kuprash, Dmitry V -- Winsauer, Caroline -- Prepens, Sandra -- Seleznik, Gitta Maria -- Eberl, Gerard -- Littman, Dan R -- Heikenwalder, Mathias -- Tumanov, Alexei V -- Nedospasov, Sergei A -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Dec 6;342(6163):1243-6. doi: 10.1126/science.1243364.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉German Rheumatism Research Center (DRFZ), a Leibniz Institute, Berlin 10117, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24311691" target="_blank"〉PubMed〈/a〉
