An Blimp-1 exprimierenden L929-Zellen wurde die Interferonproduktion mit Hilfe des RNase Protection Assay auf mRNA-Ebene quantifiziert und die Virusvermehrung im Plaquetest untersucht. In beiden F{\"a}llen bestand kein signifikanter Unterschied zu einer Kontrollpopulation ohne Blimp-1-Expression, so daß die funktionelle {\"A}quivalenz der beiden Transkriptionsfaktoren angezweifelt werden kann.}, language = {de} } @phdthesis{Xiao2004, author = {Xiao, Zheng}, title = {Blimp-1 Regulates Terminal Differentiation of T Cells}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-10530}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2004}, abstract = {The transcriptional repressor-Blimp-1 terminates differentiation of B lymphocytes as well as myeloid cells. Our data show that Blimp-1 is highly expressed in freshly isolated murine primary T lymphocytes, particularly its minor splice variant. Ectopic expression of Blimp-1 by retroviral transduction neither dramatically altered secretion of IFN-{\~a} or IL-4 nor did it induce the ability to suppress as regulatory T cells. However, induction of Blimp-1 resulted in not only a significant reduction in the production of IL-2 but also an inability to proliferate as well as in the reduced viability. These results demonstrate that Blimp-1 might mark end stages of lineage differentiation in T cells.}, language = {en} }
