In response to antigen naive CD8+, T cells differentiate into effector cells, which express Natural killer (NK) receptors, lose CD28 expression, and die by apoptosis. However, in smaller quantities, the cells are retained for subsequent exposure to the s

The rise in absolute number of CD4+ CD45RA+ cells was paralleled by an increase of CD4+ CD95/Fas− cells and accounted for most of the early increment of CD4+ cell count. The TCR Vβ repertoire of CD4+ cells was conserved after anti-HIV therapy, with the exception of two ...

In healthy carriers of human cytomegalovirus (HCMV), the virus-specific memory CD8+ T-cell population is often dominated by CD28− CD45RAhi cells that exhibit direct ex vivo cytotoxicity but whose capacity for proliferation and generation of further memory cells has been questioned. We show ...
