In addition to IPEX-like symptoms, CD25 deficiency increases susceptibility to viral infections [1] and possibly fungal and bacterial infections. As IL-2 is an important inducer of lymphocyte proliferation , the absence of highly sensitive IL-2 receptors may also significantly hinder activation and clonal expansion of CD8+ and CD4+ lymphocytes ...
Moreover, CD25 is an exclusive subunit that entirely binds IL-2, while CD132 binds the shared γc family cytokines (IL-4, IL-7, IL-9, IL-15 and IL-21), and the CD122 subunit binds also IL-15. [5] [24] [25] Soluble IL2RA has been isolated and determined to result from extracellular proteolysis during activation of T lymphocytes. [18]
IL-2 binds to the IL-2 receptor, which has three forms, generated by different combinations of three different proteins, often referred to as "chains": α (alpha) (also called IL-2Rα, CD25, or Tac antigen), β (beta) (also called IL-2Rβ, or CD122), and γ (gamma) (also called IL-2Rγ, γ c, common gamma chain, or CD132); these subunits are also parts of receptors for other cytokines.

All T cells derive from progenitor cells in the bone marrow, which become committed to their lineage in the thymus.All T cells begin as CD4-CD8-TCR- cells at the DN (double-negative) stage, where an individual cell will rearrange its T cell receptor genes to form a unique, functional molecule, which they, in turn, test against cells in the thymic cortex for a minimal level of interaction with ...
In turn, this results in the T cell acquiring an activated phenotype seen by the up-regulation of surface markers CD25 +, CD44 +, CD62L low, CD69 + and may further differentiate into a memory T cell. Having adequate numbers of naive T cells is essential for the immune system to continuously respond to unfamiliar pathogens.
The interleukin 2 receptor, which is involved in T cell-mediated immune responses, is present in 3 forms with respect to ability to bind interleukin 2.The low affinity form is a monomer of the alpha subunit (also called CD25) and is not involved in signal transduction.
