CD25 The CD25 antigen (IL-2R α chain, Tac or p55) is a single-chain glycoprotein with a molecular weight of 55 kDa which is the low affinity receptor for IL-2 (IL-2R α or IL-2R1). In conjunction with CD122 (IL-2R β , p75) and CD132 (IL-2R γ , p64), CD25 antigen forms the high-affinity IL-2R complex. CD25 is highly expressed on regulatory CD4-positive T lymphocytes and undetected on resting CD8 positive lymphocytes. However, all activated T lymphocytes express the CD25 protein. CD25 is also found on a subset of B cells (CD20 positive), on activated monocytes and macrophages, and on T cell clones. It is also expressed on NK cells enriched from peripheral blood lymphocytes by culturing in the presence of IL-2. It is absent from thymocytes, granulocytes, monocytes, resting NK cells, platelets and erythrocytes.

CD26 The CD26 antigen is the dipeptidylpeptidase IV ectoenzyme (DPPIV). It is a single-chain glycoprotein with a molecular weight of 110 kDa. It binds to adenosine deaminase protein (ADA). CD26 is a functional collagen receptor. CD26 provides an alternative activation pathway for T lymphocytes in which the CD3 ζ (TCR ζ chain) is required for CD26-mediated signaling. The expression of CD26 is found on resting T cells and is increased on activated T lymphocytes, B lymphocytes, macrophages and NK cells. In a study using this antibody, it has been suggested that CD26 is involved as a cofactor of CD4 in the mechanism of triggering apoptosis. Another study showed the expression of CD26 in human kidney and on lymphocytes and macrophages of specific skin biopsies.
