[Experimental approach to the gene therapy of motor neuron disease with the use of genes hypoxia-inducible factors].

Motor neuron disease (MND), or amyotrophic lateral sclerosis, is a fatal neurodegenerative disorder characterized by a progressive loss of motor neurons in the spinal cord and the brain. Several angiogenic and neurogenic growth factors, such as the vascular endothelial growth factor (VEGF), angiogenin (ANG), insulin-like growth factor (IGF) and others, have been shown to promote survival of the spinal motor neurons during ischemia. We constructed recombinant vectors using human adenovirus 5 (Ad5) carrying the VEGF, ANG or IGF genes under the control of the cytomegalovirus promoter.

Recombinant influenza vaccines.

This review covers the problems encountered in the construction and production of new recombinant influenza vaccines. New approaches to the development of influenza vaccines are investigated; they include reverse genetics methods, production of virus-like particles, and DNA- and viral vector-based vaccines. Such approaches as the delivery of foreign genes by DNA- and viral vector-based vaccines can preserve the native structure of antigens.

[New approaches to therapy of persistent infections: elimination of intracellular Chlamydai trachomatis by exposure to low temperature argon plasma].

Aim: Study microbicidal activity of low temperature argon plasma (LTP) that is a stream of partially ionized argon having macroscopic temperature of the environment against Chlamydia trachomatis obligate intracellular parasites. Study viability of host cells in parallel.

Materials And Methods: McCoy line cells infected with C.

[Contribution of L,D-carboxypeptidases in virulence of facultative intracellular pathogenic bacteria Listeria monocytogenes].

Aim: Evaluate influence of mutation of Listeria monocytogenes genes coding murein-tetrapeptide L,D-carboxypeptidase Lmo0028 and Lmo1638 on dynamics of infectious process and interaction of purified muropeptides with NOD1 receptor.

Materials And Methods: Wild type EGDe strain and recombinant strains GIMins1638 H GIMins0028 obtained on its basis by site-specific mutagenesis were used. Infectious process dynamics was studied on the model of intravenous infection of BALB/c mice.

Effective Genetic Expression of Nanoantibodies by Recombinant Adenoviral Vector in vitro.

The present study is devoted to the feasibility of expressing the single-domain mini-antibody (nanoantibody) selected from the library of sequences of the variable domains of special single-stranded antibodies derived from an immunized camel, a gene of which was introduced into eukaryotic cells within a recombinant adenoviral vector. A vector bearing the gene of a single-domain nanoantibody was obtained using the AdEasy Adenoviral Vector System (Stratagene). This method of delivering the nanoantibody gene facilitates efficient expression of this gene and functional activity of the nanoantibody.
