The efficient cell-mediated immune response clears cells expressing deoxyribonucleic acid (DNA) immunogens, but there are no methods to monitor this in vivo. We hypothesized that immune-mediated clearance can be monitored in vivo if DNA immunogens are coexpressed with reporter(s). To test this, we designed genes encoding human immunodeficiency virus 1(More)
Hepatitis delta virus (HDV) is a viroid-like blood-borne human pathogen that accompanies hepatitis B virus infection in 5% patients. HDV has been studied for four decades; however, the knowledge on its life-cycle and pathogenesis is still sparse. The studies are hampered by the absence of the commercially-available HDV-specific antibodies. Here, we describe(More)
Porcine parvovirus infection (PPVI) caused by a small non-enveloped virus (porcine parvovirus, PPV) is responsible for serious reproductive dysfunctions in sows. In the Russian Federation, the approved diagnostic methods for determination of parvovirus antigen and virus-specific antibodies are hemagglutination and hemagglutination-inhibition tests,(More)
The results obtained using the diagnostic kit based on real-time polymerase chain reaction to detect the DNA of the African Swine Fever in the pathological material, as well as in the culture fluid, are presented. A high sensitivity and specificity for detection of the DNA in the organs and tissues of animals was shown to be useful for detection in the(More)
Recombinant nucleocapsid (rN) protein N of porcine reproductive and respiratory syndrome virus (PRRSV) was prepared, by using the E. coli expressiom system. Insertion of a polyhistidine marker into the structure of the protein allowed the latter to be purified by metal-chelate affinity chromatography. The purity of protein was confirmed by PAAG(More)
In glioblastoma (GBM), heterogeneous expression of amplified and mutated epidermal growth factor receptor (EGFR) presents a substantial challenge for the effective use of EGFR-directed therapeutics. Here we demonstrate that heterogeneous expression of the wild-type receptor and its constitutively active mutant form, EGFRvIII, limits sensitivity to these(More)
Recent studies on the primate protection from HCV infection stressed the importance of immune response against structural viral proteins. Strong immune response against nucleocapsid (core) protein was difficult to achieve, requesting further experimentation in large animals. Here, we analyzed the immunogenicity of core aa 1-173, 1-152, and 147-191 and of(More)
