E-Mail A long noncoding RNA whose function was previously unknown turns out to play a vital role in mobilizing the immune response following a bone marrow transplant or solid organ transplantation. This RNA molecule, cataloged in scientific databases simply as Linc00402, helps activate immune defenders known as T cells in response to the presence of foreign human cells, according to a new study by researchers at the University of Michigan Rogel Cancer Center and Michigan Medicine. The investigation, which included samples from more than 50 patients who underwent a bone marrow or heart transplant, suggests inhibiting the RNA therapeutically might improve outcomes for transplant recipients. Their findings appear in
