In Science Magazine, Jennifer Couzin-Frankel reports that there is research currently going on in regards to genetically engineering immune cells to get rid of lupus. One of the experiments tested 41 mice that had lupus. All mice who were sick were then radiated to get rid of all their immune cells and then injected with these genetically altered cells. They found that of the 41 mice, 26 were completely rid of lupus and continued with a healthy life a little longer than their normal life span. The mice who received placebos all died sooner than their normal life span.
