A twice-weekly cocktail of three messenger RNAs can rejuvenate the weary immune systems of aged mice and boost responses to vaccination and cancer treatments, a study has found. The treatment provides a needed boost to immune cells called T cells, which coordinate immune responses and kill infected cells. As people age, their ability to produce T cells wanes, and the ones they have become less effective.

"Their discoveries have been decisive for our understanding of how the immune system functions and why we do not all develop serious autoimmune diseases," said Olle Kampe, chair of the Nobel Committee, in a statement.
