T cell, a type of leukocyte (white blood cell) is an essential part of the immune system at the core of adaptive immunity. Along with antibodies, T cells are part of the human immune response against viral infections. The T cells directly target and kill infected cells.The role of T cells also includes directly killing infected host cells, activating other immune cells, producing cytokines and regulating the immune response.
