[The most detailed map revealing the impact of genetic variation on the immune system has been drawn] November 4th, in three important studies recently published in the journal Nature, scientists from Australia's Garvan Institute of Medical Research, Murdoch Children's Research Institute and other institutions analyzed the gene sequence and gene activity of more than 5 million individual immune cells in nearly 2,000 people, drawing the most detailed map to date of how human genetic variation affects the immune system, and identified nearly 1,500 genes that may be involved in the occurrence of various diseases. This achievement will help discover new drug targets and promote precision treatment of cancer, immune system diseases and neurological diseases.
