Opis:
Several N4-derivatives of 6-azacytidine were synthesized using of Vorbrüggen's condensation method. Their antiviral activity with respect to the adenovirus serotypes 2 and 5 in Hep-2 cells culture was studied and primary specific activity was determined. Correlation between chemical structure of new 6-azacytidine derivatives and their biological properties is discussed.

Opis:
This review presents data on commercial and experimental virus-like particle (VLP) vaccines, including description of VLP vaccines against influenza. Virus-like particles are multimeric, sometimes multiprotein nanostructures assembled from viral structural proteins and are devoid of any genetic material. VLPs present repetitive high-density displays of viral surface proteins. Importantly, they contain functional viral proteins responsible for cell penetration by the virus, ensuring efficient cell entry and thus tissue-specific targeting, determined by the origin of the virus. The foremost application of VLPs is in vaccinology, where they provide delivery systems that combine good safety profiles with strong immunogenicity and constitute a safe alternative to inactivated infectious viruses. These stable and versatile nanoparticles display excellent adjuvant properties capable of inducing innate and cognate immune responses. They present both, high-density B-cell epitopes, for antibody production and intracellular T- cell epitopes, thus inducing, respectively, potent humoral and cellular immune responses. Uptake of VLPs by antigen-presenting cells leads to efficient immune responses resulting in control of pathogenic microorganisms.

Opis:
The aim of this study was to perform molecular analysis of canine adenovirus 2 (CAV-2) E1B 19K gene fragment isolated from 20 dogs of various breeds (12 males and 8 females aged 1-9 years), with clinical symptoms of upper respiratory tract infections, from the Lubelszczyzna region. Nasal swabs were taken from dogs. DNA of CAV-2 was detected using the PCR method in 16 swabs. All PCR products were sequenced, and the obtained sequences were compared with each other and with the sequence of the E1B 19K gene of the CAV-2 strain from an online database of NCBI GenBank: AC 000003. Based on analysis of the obtained sequences, three polymorphic variants of CAV-2 (No.1-3) with homology of 78 - 100% were distinguished. The nucleotide and amino acid sequences of the most frequently represented polymorphic variant, No. 1, differed from the sequences of polymorphic variant No. 2 with one substitution. The nucleotide and amino acid sequence of the E1B 19K gene of CAV-2 AC 000003 differed from the analogous sequences of representatives of variant No. 1 with 44 nucleotide and 19 amino acid substitutions. The small number of nucleotide differences in the E1B 19K CAV-2 gene among the examined own isolates, compared with AC 000003, suggest that the infections in dogs were caused by a relatively genetically stable virus which occurs in eastern Poland.

Opis:
Maturation of adenovirus particles is markedly affected by proteolytic processing. The possibility for blocking the conversion of precursor structural core protein (preVII) into mature structure protein VII by officinal drugs ε-aminocaproic acid and ambenum has been demonstrated in Hep-2 cells infected with adenovirus. Proteolytic processing may be regarded as one of the targets for inhibiting adenovirus reproduction.

Opis:
The concept of gene therapy was introduced with great promise and high expectations. However, what appeared simple in theory has not translated into practice. Despite some success in clinical trials, the research community is still facing an old problem: namely, the need for a vector that can deliver a gene to target cells without adverse events while maintaining a long-term therapeutic effect. Some of these challenges are being addressed by the development of hybrid vectors which meld two different viral systems to incorporate efficient gene delivery and large cloning capacity with site-specific integration. The two known systems that integrate genes into specific sites in mammalian genomes are the adeno-associated virus and phage integrases. Recent experiments with hybrid vectors incorporating both of these systems are encouraging. However, extensive research should be directed towards the safety and efficacy of this approach before it will be available for gene therapy.

Opis:
Atherosclerosis, once believed to be a result of a slow, irreversible process resulting from lipid accumulation in arterial walls, is now recognized as a dynamic process with reversibility. Liver-directed gene therapy for dyslipidemia aims to treat patients who are not responsive to currently available primary and secondary prevention. Moreover, gene therapy strategies have also proved valuable in studying the dynamics of atherosclerotic lesion formation, progression, and remodeling in experimental animals. Recent results on the long-term effect of gene therapy suggest that hepatic expression of therapeutic genes suppresses inflammation and has profound effects on the nature of the atherogenic process.
