T cellWikipedia
A T cell is a type of lymphocyte.T cells are one of the important white blood cells of the immune system and play a central role in the adaptive immune response.T cells can be easily distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface.. T cells are borne from hematopoietic stem cells found in the bone marrow.
