Ep 61: Elias Arnér, redox & EbsArgent. Ceftazidime-avibactam for P. aeruginosa treatment. FusB-mediated resistance.

In this episode, we bring you an interview with Professor Elias Arnér from the Karolinska Institute. After a long international career in redox biology, Professor Arnér became CEO of Thioredoxin Systems, the company behind a potential new antibiotic with a novel target and mode of action: EbsArgent. We explore his background, the lessons he has learned, and what makes this new drug candidate so unique.
In the news section, Elin brings us a recent article on the resistance and potential collateral sensitivity of Ceftazidime-avibactam to treat P. aeruginosa strains. Eva shares the latest publication at our center, with PhD student Adrián González López’s work on the mechanisms behind FusB-mediated resistance in Staphylococcus aureus.
We hope you enjoy this month’s episode, and see you on the next one!
