Abstract: Compositions, methods and uses employing interleukin-10 receptor (IL-10R) or interleukin 10R ligand (e.g., IL-10) antagonists for viral treatment, identification, screening and diagonistics.

Abstract: Peptides which bind to selected receptor molecules are identified by screening libraries which encode a random or controlled collection of amino acids. Peptides encoded by the libraries are expressed as fusion proteins of bacteriophage coat proteins, and bacteriophage particles are then screened against the receptors of interest. Peptides having a wide variety of uses, such as therapeutic or diagnostic reagents, may thus be identified without any prior information on the structure of the expected ligand or receptor molecule.

Abstract: Means and methods are provided for the production of mammalian viruses comprising: infecting a culture of immortalized human cells with the virus, incubating the culture infected with virus to propagate the virus under conditions that permit growth of the virus, and to form a virus-containing medium, and removing the virus-containing medium. The viruses can be harvested and be used for the production of vaccines. Advantages are that human cells of the present invention can be cultured under defined serum free conditions, and the cells show improved capability for propagating virus. In particular, methods are provided for producing, in cultured human cells, influenza virus and vaccines derived thereof. This method eliminates the necessity to use whole chicken embryos for the production of influenza vaccines. The method provides also for the continuous or batchwise removal of culture media. As such, the invention allows the large-scale, continuous production of viruses to a high titer.

Abstract: The present invention relates to the generation of replication-competent viruses having therapeutic utility. The replication-competent viruses of the invention can express proteins useful in the treatment of disease.

Abstract: The invention relates to a novel bacteriophage which is lytic for species of the genus Methylobacterium, Human Blood Bacterium (HBB) or both, and derivatives, progeny and recombinant and mutated forms thereof.

Abstract: The invention relates to the process for generating infectious Newcastle disease virus (NDV) entirely from cloned full-length cDNA and to the use of vaccines and diagnostic assays generated with and derived from said process. The process offers the possibility to modify the NDV genome by means of genetic modification and allows the introduction of mutations, deletions and/or insertions. The process can be used to modify the virulence of NDV, thereby generating new attenuated live vaccines with enhanced properties. The process can be used to modify the antigenic make-up of NDV, thus allowing the generation of live NDV marker vaccines which can be serologically distinguished from NDV field strains.

Abstract: Inhibition of HIV-1 replication by disrupting the processing of the viral Gag capsid (CA) protein (p24) from the CA-spacer peptide 1 (SP1) protein precursor (p25) is disclosed. Amino acid sequences containing a mutation in the Gag p25 protein, with the mutation resulting in a decrease in the inhibition of processing of p25 to p24 by dimethylsuccinyl betulinic acid or dimethylsuccinyl betulin, polynucleotides encoding such mutated sequences and antibodies that selectively bind such mutated sequences are also included. Methods of inhibiting, inhibitory compounds and methods of discovering inhibitory compounds that target proteolytic processing of the HIV Gag protein are included. In one embodiment, such compounds inhibit the interaction of the HIV protease enzyme with Gag by binding to Gag rather than to the protease enzyme.

Abstract: Retroviral strains of the non-M, non-O HIV-1 group, in particular a strain designated YBE30, its fragments and also its uses as a diagnostic reagent and as an immunogenic agent. The HIV-1 viruses which differ both from the M group and the O group exhibit the following characteristics: little or no serological reactivity with regard to the proteins of the M and O groups and strong serological reactivity with regard to the proteins which are derived from the strain YBF30 according to the invention or the strain CPZGAB SIV; absence of genomic amplification when using primers from the env and gag regions of the M and O HIV-1 groups; genomic amplification in the presence of primers which are derived from the YBF30 strain according to the invention; and homology of the products of the envelope gene which is greater than 70% with regard to the YBF30 strain.
