Discovery Matters – Détails, épisodes et analyse

What does 'the body as a bioreactor' mean? In this discussion how scientists use the body's machinery to produce therapeutic proteins. Scott Ripley, General Manager of Nucleic Acids at Cytiva, explains that traditional bioprocessing uses external bioreactors, while the new approach leverages the body's natural processes. This method offers benefits like longer protein half-life and the ability to express multiple proteins simultaneously. Justin Eyquem, assistant professor at University of California San Francisco, discusses the potential of in vivo CAR T cell therapy, which could simplify manufacturing and reduce costs. Both approaches face challenges in quality assurance and regulatory approval but hold promise for personalized and more effective treatments.

We're diving into advanced therapies with industry leaders. Emmanuel Abate, President of Genomic Medicine at Cytiva discussed the strategies to accelerate clinical work and reduce costs. Nathaniel Wang, CEO and Co-Founder of Replicate Bioscience highlighted their ground breaking self-replicating RNA technology, showcasing impressive clinical results for a rabies vaccine. Both experts emphasized the momentum in biotech, the potential of AI in advancing science, and the importance of making innovative therapies accessible globally. Stay tuned for these insights.

In this episode of Discovery Matters, we discuss the exciting potential of lipid nanoparticles (LNPs) to deliver genetic material and therapeutics to target cells and tissues. We are joined by Lloyd Jeffs, Senior Director of Biopharma Services at Precision NanoSystems, and Prof Dan Peer, Director of the Laboratory of Precision Nanomedicine at Tel Aviv University. Dan shares how his team has developed siRNA LNPs to deliver treatment more efficiently for ovarian cancer patients. From Dan's unique perspective, learn why this technology is cutting-edge, and why it may help defeat one of mankind’s biggest enemies— cancer.

Challenges of improving access to healthcare in developing countries - it's a conversation we need to have. With the help of Dr Jerome Kim, Director General of the International Vaccine Institute, we discuss vaccination and immunization programs as a key aspect of public health and global development – especially in developing nations, where access to life-saving medicines is often limited or non-existent. Karen Heichman, Deputy Director of Diagnostics, Bill and Melinda Gates Foundation, takes us on a journey of the critical role of diagnostics in the fight against diseases. Tune in to hear how technology and innovation could help to bridge the gap in access to healthcare and potentially save lives in the process.

Through a discussion of combination therapies, Dodi and Conor delve into the mysterious power of the human microbiome, and antimicrobial resistance. With evidence of the microbiome being a key factor in fighting diseases, this episode highlights the importance of understanding and treating the microbiome and its potential to improve lives. Tune in to find out more and explore the possibilities of the microbiome with Dr Saman Maleki, and the power of serendipity with Prof Pete Dedon!

In this episode, we dive into the potential of liquid biopsies as a method to detect deadly diseases. We speak with three experts – Marta Herreros, Rik Bryan, and Doug Ward – to learn more about the non-invasive nature of liquid biopsies and the process of detecting biomarkers within a patient sample. Rik and Doug discuss their GALEAS Bladder test, which can identify key mutations present in 96% of bladder cancer patients. Tune in to learn more about the potential of liquid biopsies and the importance of early detection!
