Nanoparticles can genetically modify several human cell types

In a demonstration that could help pave the way for gene therapies with fewer side effects, several human cell types have been genetically modified with protein nanoparticles designed at University of Michigan Engineering and Michigan Medicine. Gene therapy has been enormously successful for treating disorders of the blood, including sickle cell disease and leukemia. However, using a virus as a vector for treatment can create unwanted side effects, such as secondary cancers and immune system overreactions. With the nanoparticles, the research team aims to develop a safer method for deliveri...
