A broad strategy to reduce the toxicity of protein drugs
Therapeutic variants of the natural hormone erythropoietin (EPO) which is produced in the kidney to boost the production of red blood cells are commonly used to treat anemias stemming from kidney disease, chemotherapy and other complications. However, many drugs that are based on therapeutic proteins, including EPO, often cause unwanted side effects because they not...
DNA Nanostructures for Drug Delivery
Researchers at the Wyss Institute have developed two methods for building arbitrarily shaped nanostructures using DNA, with a focus on translating the technology towards nanofabrication and drug delivery applications. One proprietary nanofabrication technique, called “DNA-brick self-assembly,” uses short, synthetic strands of DNA that work like interlocking Lego® bricks. It capitalizes on the ability to program...
Over 15 million Americans are at risk of anaphylaxis, a severe allergic reaction triggered by exposure to certain foods, materials, medications and insect bites. Every three minutes a food reaction sends someone to the emergency room. In most individuals, anaphylactic shock can be prevented by administering the counteracting drug, epinephrine. Yet, despite effective treatments, death from...
Putting Biofilms to Work
A team at the Wyss Institute sees biofilms as a robust new platform for designer nanomaterials that could treat inflammatory bowel diseases, clean up polluted rivers, manufacture pharmaceutical products, fabricate new textiles, and more. A novel protein engineering system called BIND, which stands for Biofilm-Integrated Nanofiber Display, could be the essential ingredient in tomorrow’s probiotic...
Pathogen Capture Technology for Infectious Disease Therapeutics and Diagnostics
Microbial contamination is the cause of life-threatening cases of sepsis, meningitis and multiple other infectious diseases that are a major cause of death world-wide. Equally prevalent are pathogenic contaminants in our environment, food, and manufacturing processes. In each case, the presence of microbial contaminants must be confirmed, and when they are found, they need to...
Clinical studies take years to complete and testing a single compound can cost more than $2 billion. Meanwhile, innumerable animal lives are lost, and the process often fails to predict human responses because traditional animal models often do not accurately mimic human pathophysiology. For these reasons, there is a broad need for alternative ways to...
