- T cells are a type of white blood cells that play a central role in the adaptive immune response12. They can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface1. T cells are born from hematopoietic stem cells, found in the bone marrow1. T cells attack infected cells, foreign cells, and cancer cells and completely destroy them, stopping viruses or cancer from spreading to healthy cells2.
