WebCells T CD8+. CD8+ (cytotoxic) T cells, like CD4+ Helper T cells, are generated in the thymus and express the T-cell receptor. However, rather than the CD4 molecule, cytotoxic T cells express a dimeric co-receptor, CD8, usually composed of one CD8α and one CD8β chain. CD8+ T cells recognise peptides presented by MHC Class I molecules, found ... WebCentral memory (T CM) CD8 + T cells express L-selectin (CD62L) and the chemokine receptor CCR7, whereas effector memory (T EM) CD8 + T cells do not, and accordingly, T CM can be found surveying lymph nodes, but T EM are essentially excluded (Wherry et al., 2003).
