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]
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.
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.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
CD22 functions as an inhibitory receptor for B cell receptor (BCR) signalling. Like CD19, CD22 is a cell surface marker for lymphocytes that is present on most B cell malignancies, including acute lymphoblastic leukemia and various subtypes of non-Hodgkin lymphoma, including diffuse large B-cell lymphoma. CD22 expression has been shown to be ...
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 ...
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.
