The standard human embryonic kidney 293 (HEK293) cell line is widely used in cancer research, vaccine production, adenovirus and adeno-associated viral vectors and gene therapy. Researchers at Nationwide Children’s Hospital have discovered a new use for the HEK293 cell line: generating stable HEK293 cells expressing MiB1-FLAG and hemagglutinin (HA)–ubiquitin. MiB1-FLAG plays a vital role in cell migration and ubiquitin marks HA for degradation and affects its activity. As a result, the HEK293 cells establish a proper immune response, wound repair and tissue homeostasis while attacking hemagglutinin?????
