Immune Cell Memory

Following genetically marked donor memory T cells infused into hematopoietic stem cell transplantation patients, a team led by researchers at the University Vita-Salute San Raffaele in Milan, Italy, found that two types of less-differentiated memory T cells can persist for up to 14 years. The team’s results, published December 9 in Science Translational Medicine, demonstrate that the survival of these immune cells depends on the type of memory T cells initially introduced into patients, and whether these cells continue to encounter antigens over time.
