Abstract:
RNA-centric antisense technologies have the potential to form a foundation for the development of a new generation of antimicrobials. Upon delivery into bacteria, short antisense oligonucleotides (ASOs) can directly modulate bacterial gene expression at the RNA level. The programmable nature of such “asobiotics”, following simple base-pairing rules, allows rational and specific drug design. This opens many applications, including the rapid development of ASOs that can kill emerging pathogens, sensitize drug-resistant strains, or block expression of key virulence factors—all while sparing the native microbiome. Mirobiome editing is another exciting application, especially by targeting non-model bacteria. This talk will discuss the challenges of progressing asobiotics from a promising area of research to an applied technology capable of addressing the growing antimicrobial resistance crisis and providing solutions for the analysis of genetically intractable microbes. We will also discuss how asobiotics can be used as a versatile tool for functional genomics of phages.
