Nonstructural protein 3 (NS3) of human hepatitis C virus (HCV) is a conserved multi-functional protein essential for replication and translation of viral RNA and polyprotein processing. Early T-cell response against NS3 is capable of restricting viremia. We aimed at characterizing the immunogenicity in gene immunization of the conserved regions of NS3(More)
To enhance the penetration of oligonucleotide ('oligo') into cells, the oligo was combined with the hydrophobic undecyl residue. Using the 'DNA-synthesator', we synthesized oligo, complementary to the loop-forming site of the RNA, encoding polymerase 3 of the influenza virus (type A), and combined it with the undecyl residue added to the 5' terminal(More)
29 patients aged 6-16 with glomerulonephritis lasting 4-5 years received multimodality treatment with plasmapheresis as a component. The majority of the patients suffered from primary glomerulonephritis in mesangio- or membrano-proliferative morphological variants. Previous long-term conventional therapy (prednisolone, cytostatics, anticoagulants and(More)
Recombinant major surface glycoprotein E2 from virulent Shimen strain of classical swine fever virus (CSFV) has been tested for immunogenicity in animal immunization experiments. Immunization of 3-month-old piglets with 200 micrograms of recombinant protein protected the animals from lethal challenge with virulent CSFV strain. CSFV-specific antibody(More)
Human monoclonal antibodies (HMAB) are a powerful and pzomising therapeutic agent for the very near future. Advantages of HMAB over murine monoclonal antibodies are familiar [13, 14], but several factors have delayed their use. The first of these is the impossibility of immunizing a human being with each and every antigen, and for that reason efforts to(More)
Recombinant E2 protein from vaccine strain of classical swine fever virus (CSFV) and from SCFV virulent strain Shimen was synthesized in SF-21 and High-Five cell culture with baculovirus as the expressing vector. For secretion, hydrophobic C-terminal transmembrane domain was removed and N-terminal signal polypeptide of 38 amino acids was added. Maximum(More)
A novel approach to study the variability of consensus sites of regulatory regions of DNA is proposed. The overall strategy includes chemical synthesis of representative series of all possible DNA structures under investigation, cloning and screening according to their function. The chemical-enzymatic synthesis of a complete library of 40-bp DNA duplexes,(More)
Conditions for in vitro immunization of human lymphocytes from adult peripheral blood, tonsils and cord blood with Epstein-Barr Virus (EBV) capsid antigens have been studied. Pokeweed mitogen and B cell growth factor from Namalva cell line were shown to induce a significant production of specific antibodies by human lymphocytes stimulated with EBV. This(More)
