Description
CD45RO (an isoform of leukocyte common antigen) is expressed on most thymocytes, monocytes, macrophages and granulocytes. It is not expressed on normal B lymphocytes. Intrathymic T cell maturation progressesfrom CD45RA-/CD45RO+to CD45RA+/CD45RO-; while peripheral T cell maturation progresses from CD45RA+/CD45RO- to CD45RA- /CD45RO+.
