Front Mol Biosci
August 2023
Department of Bioinformatics, School of Life Sciences, Pondicherry University (A Central University), Pondicherry, India.
Article Synopsis
- The pathogen discussed causes various infections, especially in people with weakened immune systems, and exhibits drug resistance through quorum sensing (QS) mechanisms, which affect its pathogenicity.* -
- Selenium nanoparticles (SeNPs) show potential as a treatment for these infections, despite limited existing research on their mechanisms and interactions with QS signaling proteins.* -
- The study uses computational methods to demonstrate that SeNPs effectively bind to key QS proteins, potentially inhibiting their function and blocking the production of harmful signaling molecules, thereby reducing the pathogen's virulence.*
