The response of rat thymus nuclei to thyroid hormones
… on the protein, RNA and DNA fractions of the thymus nuclei of growth-arrested sulfaguanidine-fed rats has been studied. A single dose of 15 µg of L-T₃ stimulated the incorporation of ¹⁴C-labelled amino acids into total nuclear protein, whole histone and histone fractions. The incorporation of …

Expressionsmuster Gewebe-spezifischer Antigene in Thymus-Epithelzellen der Maus
… verschiedener Gewebe-spezifischer Gene in Thymus-Epithelzellen auf Einzelzellebene zu untersuchen. mRNA und Proteinexpression wurde für Insulin, P1A, PLP, MOG, Somatostatin und S100beta gefunden. Diese Antigene (bis auf MOG) wurden in medullären Epithelzellen des Thymus exprimiert, die …

Defining The Molecular Networks Necessary For Thymus Fate and Organogenesis
<p>The thymus and parathyroid (PT) glands originate from endodermal progenitors in the bilateral third pharyngeal pouches (3<sup>rd</sup> pps). By E11.5 during mouse development, cells committed to the thymus lineage express <em>Foxn1 </em>whereas PT-fated cells express <em>Gcm2</em>. While these …

PURIFICATION OF THE REGULATORY SUBUNIT OF RIBONUCLEOSIDE DIPHOSPHATE REDUCTASE FROM CALF THYMUS
… ribonucleoside diphosphate reductase from calf thymus has been purified to homogeneity, as demonstrated by the observation of a single band on SDS-polyacrylamide electrophoresis gels. The purification procedure involved the use of conventional techniques under conditions known to induce specific …

Phenotypic and functional analysis of the mesenchymal stromal cell compartment in the thymus
… of chronic inflammation and autoimmunity. The thymus constitutes the body's major T cell production site, where bone marrow-derived progenitors migrate in a co-ordinated fashion through anatomically distinct cortical and medullary regions that are composed of epithelial and mesenchymal stromal …

Untersuchung der Entwicklung der T-Zell-Rezeptor assoziierten Signalleitung im Thymus auf Einzelzellniveau
Die frühe Entwicklung der ab-T-Zelllinie scheint von Zytokinen abhängig zu sein, vor allem von IL-7, das bei dieser Kontrolle eine wichtige Rolle spielt. Die späteren Differentierungsereignisse hingegen sind vom CD3-Komplex kontrolliert. Die Umstellung von Zytokin- zu CD3-Kontrolle in der …

PHYSICOCHEMICAL STUDIES ON THE CATALYTIC AND REGULATORY SUBUNITS OF RIBONUCLEOTIDE REDUCTASE FROM CALF THYMUS
… (M2) and regulatory (M1) subunits of calf thymus ribnucleotide reductase have been purified to homogeneity. Each runs as a single band in SDS-polyacrylamide gel electrophoresis with polypeptide molecular weights of 84,000 for M1 and 58,000 for M2. Additional evidence for homogeneity was …

Investigating lymphocyte development in the foetal thymus and modulation by the melanocortin 5 receptor
… (NK) cells are generated in the bone marrow and thymus, whilst T cell development is restricted to the thymus. Once in the tissues, these cells respond to microenvironmental cues that refine their responses, for example, via receptor-mediated cell-cell contacts, soluble cytokines and …
