CD4+ T cells specific for glycoprotein B from cytomegalovirus exhibit extreme conservation of T-cell receptor usage between different individuals

Abstract excerpt

Antigen-specific CD8(+) cytotoxic T cells often demonstrate extreme conservation of T-cell receptor (TCR) usage between different individuals, but similar characteristics have not been documented for CD4(+) T cells. CD4(+) T cells predominantly have a helper immune role, but a cytotoxic CD4(+) T-cell subset has been characterized, and we have studied the cytotoxic CD4(+) T-cell response to a peptide from human...
