Abstract: The research on new targeting delivery systems of pharmacologically active molecules and genetic material is of great importance. The aim of the work is to investigate the potential of cationic phosphorus-containing dendrimer of 4 generation (P4) as drug and gene delivery carrier. We studied the interaction between P4 and model drug – fluorescent probe ANS. The binding constant and the number of binding centers per one molecule of P4 was determined. At the second step the dendriplex between P4 and anti-HIV siRNA siP24 was characterized by means of circular dichroism, fluorescence polarization, zeta-potential methods; an average hydrodynamic diameter of dendriplex was evaluated by zeta-size measurements. The third part of our work includes estimation of the efficiency of transfection of green fluorescent protein gene (pGFP) by P4 in HEK293 cells and mesenchymal stem cells; the cytotoxicity of P4-pGFP dendriplex was also checked. As the conclusion it can be stated that cationic phosphorus-containing dendrimer (P4) of 4 generation is good candidate to be applied as drug and gene delivery carrier.

Title: The Adenovirus-Mediated Immune Response and VA-RNA

Abstract: The major limitation of clinical use of replication-incompetent adenovirus (Ad) vectors is innate immune responses, including induction of inflammatory cytokines and interferons, following in vivo application of Ad vectors. Ad vector-induced production of inflammatory cytokines and interferons also results in severe organs damages and efficient induction of acquired immune responses against Ad proteins and transgene products. Ad vector-induced innate immune responses are triggered by recognizing the Ad components by pattern recognition receptors (PRRs). In order to reduce the side effects by Ad vector-induced innate immune responses and to develop the safer Ad vectors, it is highly crucial to clarify which PRRs and which of the Ad components are involved in Ad vector-induced innate immune responses. Our group previously demonstrated that myeloid differentiating factor 88 (MyD88) and toll-like receptor 9 (TLR9) plays a crucial role on the Ad vector-induced inflammatory cytokine production in mouse bone marrow-derived dendritic cells. Furthermore, our group recently found that virus associated RNAs (VA-RNAs), which are about 160 nucleotide-long non-coding small RNA encoded in the Ad genome at bp 10620-10779 and bp 10876-11038, are involved in interferon production through IPS-1-mediated signaling pathway following Ad vector transduction. The aim of this review is to highlight the Ad vector-induced innate immune responses following transduction, especially VA-RNAs-mediated innate immune responses. The findings in the mechanism of the Ad vector-induced innate immune responses would largely contribute to the development of the safer Ad vectors, such as an Ad vector lacking expression of VA-RNAs.

Abstract: Gene and siRNA delivery can particularly be used for the treatment of diseases by the insertion of genetic materials into mammalian cells either to express new proteins or to prevent the expression of proteins, respectively. Polyamidoamine (PAMAM) dendrimers, of which ease of synthesis with controlled structure and size, minimal cytotoxicity, and high transfection efficiencies, are used as a support material for gene and siRNA delivery. Recently, multifunctional PAMAM dendrimers can be used for the wide range of biomedical applications including the interaction and intracellular delivery of genetic materials. In this context, this review paper provides the recent development on PAMAM dendrimer conjugates with cyclodextrins (CyDs) having multifunctional moieties for gene and siRNA delivery.
