Penn Dental Professor Henry Daniell works out of a greenhouse at Penn’s South Bank campus. His life’s work centers on a unique means of delivering drugs and vaccinations to the human body. Instead of relying upon sterile injections to ferry the therapeutic protein of interest to the intended tissue, Daniell has used a humbler vehicle: lettuce leaves. His research has demonstrated the effectiveness of plant-based vaccines and therapeutics in treating nearly 30 conditions, from cholera, malaria, and anthrax, to diabetes and hemophilia.
