Yet, until recently no general (bio)marker or reporter gene was described that could be used to evaluate successful tumor colonization and/or transgene expression in other biological therapies. Methods: Here, a bacterial glucuronidase (GusA) encoded by biological therapeutics (e.g. oncolytic viruses) was used as reporter system. Results: Using fluorogenic probes that were specifically activated by glucuronidase we could show 1) preferential activation in tumors, 2) rena l excretion of the activated fluorescent compounds and 3) reproducible detection of GusA in the serum of oncolytic vaccinia virus treated, tumor bearing mice in several tumor models. Time course studies revealed that reliable differentiation between tumor bearing and healthy mice can be done as early as 9 days post injection of the virus. Regarding the sensitivity of the newly developed assay system, we could show that a single infected tumor cell could be reliably detected in this assay. Conclusion: GusA therefore has the potential to be used as a general marker in the preclinical and clinical evaluation of (novel) biological therapies as well as being useful for the detection of rare cells such as circulating tumor cells}, subject = {Virologie}, language = {en} } @article{ErlweinRethwilm1993, author = {Erlwein, Otto and Rethwilm, Axel}, title = {BEL-1 transactivator responsive sequences in the long terminal repeat of human foamy virus}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-61402}, year = {1993}, abstract = {No abstract available}, subject = {Virologie}, language = {en} } @article{SchneiderSchauliesSchneiderSchauliesSchusteretal.1994, author = {Schneider-Schaulies, Sibylle and Schneider-Schaulies, J{\"u}rgen and Schuster, A. and Bayer, M. and Pavlovic, J. and ter Meulen, V.}, title = {Cell type specific MxA-mediated inhibition of measles virus transcription in human brain cells}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-62255}, year = {1994}, abstract = {No abstract available}, subject = {Virologie}, language = {en} } @article{NeumannHaefelinRethwilmBaueretal.1983, author = {Neumann-Haefelin, D. and Rethwilm, Axel and Bauer, G. and Gudat, F. and zur Hausen, H.}, title = {Characterization of a foamy virus isolated from Cercopithecus aethiops lymphoblastoid cells}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-61538}, year = {1983}, abstract = {A virus derived from cells of a Iymphoblastoid line originating from the lymph node of a healthy African green monkey was characterized as a typical member of the foamy virus subgroup of rctroviridac by its morphological, physicochemical, biological and biochemical properties (reverse transcriptase actvity).

It is, however, the surface interaction of the viral glycoprotein (gp) complex with receptors present on lymphocytes and dendritic cells (DCs), that signals effective initiation of host cell cytoskeletal dynamics. For DCs, these may act to regulate processes as diverse as viral uptake and sorting, but also the ability of these cells to successfully establish and maintain functional immune synapses (IS) with T cells. In T cells, MV signaling causes actin cytoskeletal paralysis associated with a loss of polarization, adhesion and motility, which has been linked to activation of sphingomyelinases and subsequent accumulation of membrane ceramides. MV modulation of both DC and T cell cytoskeletal dynamics may be important for the understanding of MV immunosuppression at the cellular level.}, subject = {Virologie}, language = {en} } @article{AguzziBothAnhauseretal.1992, author = {Aguzzi, A. and Both, K. and Anhauser, I. and Horak, I. and Rethwilm, Axel and Wagner, EF.}, title = {Expression of human foamy virus is differentially regulated during development in transgenic mice}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-55290}, year = {1992}, abstract = {Tbe human foamy virus (HFV) is a recently characterized member ofthe spumavirus family. Although no diseases have been unequivocally associated with HFV infection, expression of HFV regulatory genes in transgenie mice induces a characteristic aeute neuro degenerative disease and a myopathy. To better eharaeterize the sequenee of events leading to disease, and to gain a better understanding of the underlying pathogenetic meehanisms, we have analyzed in detail the transgene expression pattern during development. Transcription of a construet containing all regulatory elements and aneillary genes of mv was analyzed by in situ hybridization and was shown to occur in two distinct phases. At midgestation, low but widespread expression was first deteeted in eells of extraembryonie tissues. Later, various tissues originating from embryonie mesoderm, neuroeetoderm, and neural erest transeribed the transgene at moderate levels. However, expression deereased dramatically during late gestation and was suppressed shortly after birth. After a latency period of up to 5 weeks, transeription of the transgene resumed in single eelJs distributed irregularly in the central nervous system and in the skeletal museIe. By the age of 8 weeks, an increasing number of eells displayed much higher expression levels than in embryonie Iife and eventually underwent severe degenerative ehanges. These findings demonstrate that HFV transgene expression is differentially regulated in development and that HFV cytotoxicity may be dose-dependent. Such biphasic pattern of expression differs from that of murine retroviruses and may be explained by the specificity of HFV regulatory elements in combination with cellular faetors. Future studies of this model system should, therefore, provide novel insights in the mechanisms controlling retrovirallatency.}, subject = {Virologie}, language = {en} } @article{SchneiderSchauliesKrethHofmannetal.1991, author = {Schneider-Schaulies, Sibylle and Kreth, H.
