Herpesviruses constitute a family of large DNA viruses widely spread in vertebrates and causing a variety of different diseases. They possess dsDNA genomes ranging from 120 to 240 kbp encoding between 70 to 170 open reading frames. We previously reported the protein interaction networks of two herpesviruses, varicella-zoster virus (VZV) and Kaposi's(More)
The rapid cleavage stage of early sea urchin development is characterized by the transient synthesis of a specific set of proteins. These proteins were identified by comparing the pattern of newly synthesized proteins from fully grown sea urchin oocytes, unfertilized and fertilized eggs, several embryonic stages, and adult tissues by one- and(More)
Prion diseases are fatal neurodegenerative disorders in man and animal associated with conformational conversion of a cellular prion protein (PrPc) into the pathologic isoform (PrPSc). The function of PrPcand the tertiary structure of PrPScare unclear. Various data indicate which parts of PrP might control the species barrier in prion diseases and the(More)
A new subtype (MVP-5180) of human immunodeficiency virus type 1 (HIV-1) was isolated from a Cameroonian AIDS patient. MVP-5180 was grown in several human T-cell lines and the monocytic U937 line. MVP-5180 DNA could not be amplified by nested primer PCR with conventional env primers and could be only very faintly amplified with gag and pol primers. Most(More)
Hepatitis B virus is a major cause of human liver disease. In the case of chronic infection the virus can lead to liver cancer and cirrhosis. The virion consists of an outer envelope containing lipids of the endoplasmic reticulum and virally-encoded surface proteins. This lipoprotein shell encloses the nucleocapsid or core antigen (HBcAg), which contains(More)
Coronaviruses (CoVs) are important human and animal pathogens that induce fatal respiratory, gastrointestinal and neurological disease. The outbreak of the severe acute respiratory syndrome (SARS) in 2002/2003 has demonstrated human vulnerability to (Coronavirus) CoV epidemics. Neither vaccines nor therapeutics are available against human and animal CoVs.(More)
To probe into the functional properties of the major peripheral myelin cell surface glycoprotein P0, its ability to confer adhesion and neurite outgrowth-promoting properties was studied in cell culture. To this aim, P0 was expressed as integral membrane glycoprotein at the surface of CV-1 cells with the help of a recombinant vaccinia virus expression(More)
The severe acute respiratory syndrome coronavirus (SARS-CoV) genome is predicted to encode 14 functional open reading frames, leading to the expression of up to 30 structural and non-structural protein products. The functions of a large number of viral ORFs are poorly understood or unknown. In order to gain more insight into functions and modes of action(More)
Antigens in a particulate conformation were shown to be highly immunogenic in mammals. For this reason, the particle forming capacity of derivatives of the HIV-1 group specific core antigen p55 gag was assayed and compared dependent on various expression systems: recombinant bacteria, vaccinia- and baculoviruses were established encoding the entire core(More)
Heat inactivation of parvovirus B19 (B19) was studied in a culture of hematopoietic progenitor cells generated in vitro from peripheral human blood. After inoculating cell cultures with identical volumes of plasma (MII) containing B19 (B19-MII) heat-treated (60 degrees C) for various periods of time, a time-dependent inactivation of the input virus was(More)
