Viruses are specialists at replicating, something that has frustrated researchers for an HIV cure — until now. With advances in gene editing, the private company Excision BioTherapeutics seems to have developed a functional cure for HIV in animals by removing genomes. Today we speak with Excision CEO Daniel Dornbusch about their breakthrough and why, after decades, gene editing is now attracting significant attention. We open our conversation by talking about what gene editing is, its connections to health science, and how top minds have been experimenting with CRISPR to prevent viral infection. Daniel shares details on his company’s approach to an HIV cure while emphasizing that their research is derived from a community of scientific thought. From CasX to Cas9, we chat about different CRISPR proteins and how each has its abilities and aptitudes. After touching on the challenges of balancing effective gene editing with safety, Daniel provides his insights into why technological leaps have led to an explosion in the gene editing field. We then discuss how gene editing has accelerated the development of a Covid-19 vaccine before we ask Daniel for his take on the controversial 2018 story, when scientists allegedly edited the genes of babies. Near the end of the episode, we talk about other approaches to curing HIV and Daniel leaves us with a final message. Tune in to hear more about the exciting application of gene editing and what Daniel has done to push for an HIV cure.
(Daniel: “I should have thanked our collaborators at Temple University, Dartmouth College and UC Berkeley for their innovations and tireless work over the years.”)
“With every drug, and throughout the history of drugs, there’s always a balance between efficacy and safety.” — Daniel Dornbusch
“Gene editing has been a cornerstone of why we’ve moved so fast with new vaccines for the coronavirus.” — Daniel Dornbusch
