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...
Fluorescent In Situ Sequencing (FISSEQ)
Working copies of active genes — called messenger RNAs or mRNAs —translate the genetic information present in DNA into proteins within the cells’ multiple compartments. They are often positioned strategically within cells in ways that contribute critically to how cells and tissues grow, develop and function, and their mislocation can lead to disease development. To...
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...
Mechanically-Activated Drug Targeting Nanotechnology
The Wyss team has developed a novel drug targeting nanotechnology that is activated locally by mechanical forces, either endogenous high shear stresses in blood created by vascular occlusion or mechanical energy applied locally using low-energy ultrasound radiation. Today, vascular blockage is the leading cause of death and disability in United States and Europe. Current therapies...
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...
Multiplexed Molecular Force Spectroscopy
Programmable DNA nanoswitches, invented at the Wyss Institute, can now be used in combination with a benchtop Centrifuge Force Microscope (CFM) as a highly reliable tool to observe thousands of individual molecules and their responses to mechanical forces in parallel. By analyzing the responses of single molecules under conditions where they experience such forces, it is possible...
