The master gene that causes blood stem cells to turn into disease-fighting 'Natural Killer' (NK) immune cells has been identified by scientists, in a study published in Nature Immunology Setember 13. The discovery could one day help scientists boost the body's production of these frontline tumor-killing cells, creating new ways to treat cancer. The researchers have 'knocked out' the gene in question, known as E4bp4, creating the world's first animal model entirely lacking NK cells. (source: sciencedaily.com)
