Decreased naive T cell proportion Abnormal naive CD8+ T cell proportion Decreased naive CD8+ T cell proportion 2019-04-05T14:40:51Z Abnormal decrease of the naive CD8+ T cell subpopulation, commonly characterized as CD45RA+, CD45RO-, or CD27+, measured as percentage of total CD8+ T cells in the blood, compared to a reference range for a given sex and age-group. These cells are sometimes also characterized as CD62L+ and CCR7+.
