  abstract  = {Rhesus monkeys (M. mulatta) were i.v. infected with SIV mac251. Three phases of lymph node changes were observed. 1: physiological follicular hyperplasia (3 and 6 weeks p.i.). 2: Alterations of germinal centers: loss of follicular mande zone, fragmentation or sclerosis (12 and 24 weeks p.i.). 3: Partial depletion of T-lymphocytes, accumulation of plasma cells, increased numbers of syncytial giant cells, hemophgocytosis in the sinuses (ab out 1 year p.i.). The thymus of the juvenile animals showed first changes 12 and 24 weeks after infection with focalloss of immature (and Ki-67 positive) cortical thymocytes, leading to severe accidental involution of the thymuses one year after infection and reduced numbers of Hassalls corpuscles. These investigations show the value of this animal model for the study of morphology and pathogenesis of AIDS.},

The animals developed a progressive degenerative disease of tbe centrat nervous system and of the striated muscle. Because expression of tbe transgene was dosely correlated witb the appearance of structural damage and inflammatory reactions were scanty, the disease is likely to be caused directly by tbe HFV proteins. These unexpected findings call for a reevaluation of tbe patbogenic potential of HFV in humans.},

  abstract  = {The human foamy virus (HFV) contains within the UJ region of its long terminal repeat (L TR) three perfect consensus sequences for the binding of the inducible transcription factor AP-1. Results of DNase I footprint protection and gel retardation assays demonstrated that proteins in extracts of HeLa and BHK-21 cells as weil as bacterially expressed Jun and Fos proteins bind to these AP-1 sites. By conducting transient expression assays using chloramphenicol acetyltransferase plasmids carrying LTR sequences with point-mutated AP-1 sites it was found that the three AP-1 sites contribute to the optimal activity ofthe HFV promoter. It is shown that lnduction of the HFV L TR by 12-O-tetradecanoylphorbol-13-acetate (TPA) and serum factors is mediated through the AP-1 sites.},

  abstract  = {The human foamy virus (HFV) genome possesses three open reading frames (bel I, 2, and 3) located between env and the 3' long terminal repeat. By analogy to other human retroviruses this region was selected as the most Iikely candidate to encode the viral transactivator. ResuIts presented here confirmed this and showed further that a deletion introduced only into the bell open reading frame of a plasmid derived from an infectious molecular clone of HFV abolished transactivation. In contrast, deletions in bel 2 and bel 3 had only minor effects on the ability to transactivate. The role of the bel I genomic region as a transactivator was further investigated by eukaryotic expression of a genome fragment of HFV spanning the bel I open reading frame. A construct expressing bell under control of a heterologous promoter was found to transactivate the HFV long terminal repeat in a dose-dependent fashion. Furthermore, it is shown that the U3 region of the HFV long terminal repeat is sufficient to respond to the HFV transactivator.},
