Decreased CD4+ memory T cell proportion Decreased proportion of central memory CD4-positive T cells 2019-04-05T15:28:40Z A reduced proportion of central memory CD4-positive memory T cells compared to the total number of T cells in the blood. These cells have the phenotype of CCR7-positive, CD127-positive, CD45RA-negative, CD45RO-positive, and CD25-negative. Decreased proportion of CD4+ central memory cells An abnormally decreased proportion of central memory CD4+ T cells. These are memory cells that are located in the secondary lymphoid organs. These cells may have a CD3/CD4/CD62L+/CD45RA- phenotype. Decreased proportion of CD4-positive central memory cells HP:0025622 Reduced proportion of CD4+ central memory cells Decreased proportion of central memory CD4+, alpha-beta T cell
