Therefore, generally, only the distinction between naive and memory CD4 T cells is made. Abnormal CD4+ memory T cell proportion HP:0410381 HP:0410382 Abnormal increase or decrease of the memory CD4+ T cell subpopulation, commonly characterized as CD45RA-, CD45RO+, or CD27-, measured as percentage of total CD4+ T cells in the blood, compared to a reference range for a given sex and age-group.
