    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〉

    Description: The impact of nutritional status during fetal life on the overall health of adults has been recognized; however, dietary effects on the developing immune system are largely unknown. Development of secondary lymphoid organs occurs during embryogenesis and is considered to be developmentally programmed. Secondary lymphoid organ formation depends on a subset of type 3 innate lymphoid cells (ILC3) named lymphoid tissue inducer (LTi) cells. Here we show that mouse fetal ILC3s are controlled by cell-autonomous retinoic acid (RA) signalling in utero, which pre-sets the immune fitness in adulthood. We found that embryonic lymphoid organs contain ILC progenitors that differentiate locally into mature LTi cells. Local LTi cell differentiation was controlled by maternal retinoid intake and fetal RA signalling acting in a haematopoietic cell-autonomous manner. RA controlled LTi cell maturation upstream of the transcription factor RORgammat. Accordingly, enforced expression of Rorgt restored maturation of LTi cells with impaired RA signalling, whereas RA receptors directly regulated the Rorgt locus. Finally, we established that maternal levels of dietary retinoids control the size of secondary lymphoid organs and the efficiency of immune responses in the adult offspring. Our results reveal a molecular link between maternal nutrients and the formation of immune structures required for resistance to infection in the offspring.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van de Pavert, Serge A -- Ferreira, Manuela -- Domingues, Rita G -- Ribeiro, Helder -- Molenaar, Rosalie -- Moreira-Santos, Lara -- Almeida, Francisca F -- Ibiza, Sales -- Barbosa, Ines -- Goverse, Gera -- Labao-Almeida, Carlos -- Godinho-Silva, Cristina -- Konijn, Tanja -- Schooneman, Dennis -- O'Toole, Tom -- Mizee, Mark R -- Habani, Yasmin -- Haak, Esther -- Santori, Fabio R -- Littman, Dan R -- Schulte-Merker, Stefan -- Dzierzak, Elaine -- Simas, J Pedro -- Mebius, Reina E -- Veiga-Fernandes, Henrique -- R01 AI080885/AI/NIAID NIH HHS/ -- R01AI080885/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Apr 3;508(7494):123-7. doi: 10.1038/nature13158.
