The rhesus macaque CD25 (RhCD25) cDNA isolated from rhesus PBMCs was found to share 95.5 and 91.9% homology with the human orthologue at the nucleotide and amino acid levels, respectively. Comparative sequence analyses suggest that both human CD25 (HuCD25) and RhCD25 share identity for most of the critical amino acids previously identified to be essential for viable folding and IL-2 ligand binding. The human leukemic cell line, HH, deficient for IL-2Ralpha was transduced with a lentiviral vector (LV) engineered to express RhCD25 (HH-RhCD25). RhCD25 was characterized for expression by flow cytometric analyses, ELISA, Western blotting, functional signalling, and biological assays in comparison to HuCD25. In summary, vectors expressing the RhCD25 cDNA can be used as a tool to aid in the characterization of soluble CD25 in non-human primate studies, and to provide a tempting alternative as an autologous cell surface marker in rhesus macaque gene therapy and bone marrow transplantation studies.
