Biosafety Evaluation of a Chimeric Adenoviral Vector in Mini-Pigs: Insights into Immune Tolerance and Gene Therapy Potential.

Background: The biosafety of gene therapy products remains a major challenge to their introduction into the clinic. In particular, the problem of immunogenicity of viral vectors is the focus of attention. Large animals such as pigs, whose anatomical and physiological characteristics are similar to those of humans, have an advantage in testing vector systems.

Rational Design of Drugs Targeting G-Protein-Coupled Receptors: Ligand Search and Screening.

G protein-coupled receptors (GPCRs) are transmembrane proteins that participate in many physiological processes and represent major pharmacological targets. Recent advances in structural biology of GPCRs have enabled the development of drugs based on the receptor structure (structure-based drug design, SBDD). SBDD utilizes information about the receptor-ligand complex to search for suitable compounds, thus expanding the chemical space of possible receptor ligands without the need for experimental screening.

Rational Design of Drugs Targeting G-Protein-Coupled Receptors: A Structural Biology Perspective.

G protein-coupled receptors (GPCRs) play a key role in the transduction of extracellular signals to cells and regulation of many biological processes, which makes these membrane proteins one of the most important targets for pharmacological agents. A significant increase in the number of resolved atomic structures of GPCRs has opened the possibility of developing pharmaceuticals targeting these receptors via structure-based drug design (SBDD). SBDD employs information on the structure of receptor-ligand complexes to search for selective ligands without the need for an extensive high-throughput experimental ligand screening and can significantly expand the chemical space for ligand search.
