CD8 T cells proliferate and initially differentiate into which type of lymphocyte?

CD8 T cells proliferate and initially differentiate into which type of lymphocyte? Correct Answer Cytotoxic T lymphocyte (CTL)

CD8 T cells proliferate and progressively differentiate into Cytotoxic T lymphocytes (CTLs). The proliferation of CD8 T cells require repeated encounters with antigens. This antigenic stimulus triggers the developmental process and hence it causes differentiation of CD8 T cells. As and when the entire developmental process is completed by committing CD8 T cells to differentiate, they activate Tumour-necrosis factor and kill infected cells.
