Background | CD45RO is a 180 kD single chain membrane glycoprotein. It is a splice variant of tyrosine phosphatase CD45, lacking the A, B, and C determinants. The CD45RO isoform is expressed on activated and memory T cells, some B cell subsets, activated monocytes/macrophages, and granulocytes. CD45RO enhances both T cell receptor and B cell receptor signaling mediated activation. CD45 and its isoforms non-covalently associate with lymphocyte phosphatase-associated phosphoprotein (LPAP) on T and B lymphocytes. CD45 has been reported to be associated with several other cell surface antigens including CD1, CD2, CD3, and CD4. CD45 has also been reported to bind galectin-1 and CD22. CD45 isoform expression can change in response to cytokines. |

Q1:What is the difference between Human CD45RA and CD45RO?
CD45 is a receptor-type tyrosine phosphatase, also known as cluster of differentiation 45, that affects multiple signaling pathways, including T cell receptor (TCR) and B cell receptor (BCR) by regulating tyrosine phosphorylation levels. CD45 widely exists on the surface of hematopoietic cell membrane and is expressed on all leukocyte. Six isomers have been identified according to their extracellular epitopes, while CD45RA, CD45RB and CD45RO, have been identified on the surface of human cells. Then, two new subgroups of T cells can be identified by using this isomer molecule. CD45RA+ T cells are regarded as naive T cells (Tn) which means they are not stimulated by antigen , while CD45RO+ cells are known as memory T cells (Tm) been stimulated and differentiated by antigen.
