Distribution of human CMV-specific memory T cells among the CD8pos. subsets defined by CD57, CD27, and CD45 isoforms

Abstract excerpt

Chronic antigenic stimulation has been associated with peripheral blood expansions of CD8pos. T cells characterized by CD57 expression, loss of CD27 expression, and reversal of the CD45RO(bright) /RA(dim) phenotype usually associated with immunological memory towards a CD45RO(dim) /RA(bright) phenotype. However, the relationship and functional significance of these subset(s) has remained controversial. Here, this...
