Oligomeric S100A4 Is Associated With Monocyte Innate Immune Memory and Bypass of Tolerance to Subsequent Stimulation With Lipopolysaccharides
Conclusion: Bypass of tolerance by DAMPs might be a phenomenon as important as TI, since it could explain how chronic inflammation can be maintained in spite of an environment with multiple TLR2/TLR4-ligands. In RA monocytes, a PRDM8-dependent TI mechanism could be responsible for sustained chemokine/cytokines levels. Introduction Monocytes and macrophages play a central role in the pathophysiology of inflammation. For instance, in rheumatoid arthritis (RA), activated monocytes massively infiltrate synovial tissues and produce tumor necrosis factor-α (TNFα) (1–3). Accordingly, therapies aime...

Knockdown of FLT4, Nup98, and Nup205 cellular genes effectively suppresses the reproduction of influenza virus strain A/WSN/1933 (H1N1) in vitro
CONCLUSION: We identified a number of genes such as FLT4, Nup98, and Nup205, the decrease in the expression of which can effectively suppress viral reproduction. The original siRNA sequences were also obtained. These results are important for the creation of therapeutic and prophylactic agents, whose action is based on the RNA interference mechanism.PMID:35339191 | DOI:10.2174/1871526522666220325121403

Evaluation of a DoE based approach for comprehensive modelling of the effect of lipid nanoparticle composition on nucleic acid delivery
Biomaterials. 2023 May 15;299:122158. doi: 10.1016/j.biomaterials.2023.122158. Online ahead of print.ABSTRACTTherapeutic nucleic acids (TNAs) comprise an alternative to conventional drugs for cancer therapy. Recently, stable nucleic acid lipid particles (SNALPs) have been explored to deliver TNA efficiently and safely both in vitro and in vivo. Small interfering RNA (siRNA) and messenger RNA (mRNA) based drugs have been suggested for a wide range of pathologies, and their respective lipid nanoparticle (LNP) formulations have been optimised using a Design of Experiments (DoE) approach. However, it is uncertain as to whether...

Aptamer-targeted inhibition of mTOR in T cells enhances antitumor immunity
Recent studies have underscored the importance of memory T cells in mediating protective immunity against pathogens and cancer. Pharmacological inhibition of regulators that mediate T cell differentiation promotes the differentiation of activated CD8+ T cells into memory cells. Nonetheless, pharmacological agents have broad targets and can induce undesirable immunosuppressive effects. Here, we tested the hypothesis that aptamer-targeted siRNA inhibition of mTOR complex 1 (mTORC1) function in CD8+ T cells can enhance their differentiation into memory T cells and potentiate antitumor immunity more effectively than the pharma...

Proapoptotic and Antiapoptotic Proteins of the Bcl-2 Family Regulate Sensitivity of Pancreatic Cancer Cells Toward Gemcitabine and T-Cell–mediated Cytotoxicity
In conclusion, expression of Bcl-2, Bcl-xL, and Bax in pancreatic tumor cells determines sensitivity towards both Gem-mediated and CTL-mediated toxicity. Bcl-2 silencing could be exploited therapeutically in tumor vaccine approaches.

Efficient delivery of nucleic acid molecules into skin by combined use of microneedle roller and flexible interdigitated electroporation array
Rationale: Delivery of nucleic acid molecules into skin remains a main obstacle for various types of gene therapy or vaccine applications. Here we propose a novel electroporation approach via combined use of a microneedle roller and a flexible interdigitated electroporation array (FIEA) for efficient delivery of DNA and siRNA into mouse skin.Methods: Using micromachining technology, closely spaced gold electrodes were made on a pliable parylene substrate to form a patch-like electroporation array, which enabled close surface contact between the skin and electrodes. Pre-penetration of the skin with a microneedle roller resu...

Silencing of the foot-and-mouth disease virus internal ribosomal entry site by targeting relatively conserved region among serotypes
AbstractFoot-and-mouth disease (FMD) is a host-restricted disease of cloven-hoofed animals, such as cattle and pigs. There are seven major serotypes of FMD virus that exhibit high antigenic variation, making vaccine strain selection difficult. However, there is an internal ribosomal entry site (IRES) element within the 5 ′ untranslated region of the FMD virus (FMDV) RNA genome that is relatively conserved among FMDV serotypes and could be used as a pan-serotype target for disease interventions. To determine the potential for targeting the IRES as promising drug target, we designed a short interfering RNA (siRNA) t argeti...

HIV-1, human interaction database: current status and new features
The ‘Human Immunodeficiency Virus Type 1 (HIV-1), Human Interaction Database’, available through the National Library of Medicine at http://www.ncbi.nlm.nih.gov/genome/viruses/retroviruses/hiv-1/interactions, serves the scientific community exploring the discovery of novel HIV vaccine candidates and therapeutic targets. Each HIV-1 human protein interaction can be retrieved without restriction by web-based downloads and ftp protocols and includes: Reference Sequence (RefSeq) protein accession numbers, National Center for Biotechnology Information Gene identification numbers, brief descriptions of the interaction...
