CD25 consists of three domains: extracellular (N-terminus), transmembrane (alpha-helix) and cytoplasmic (C-terminus). However, while extracellular part is able to function as a binding site for interleukin-2 , short cytoplasmic domain lacks an ability to induce intracellular signalling and therefore needs to oligomerise with other IL-2 receptor ...
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.
Mature CD25+Foxp3+ Tregs can be also divided into two different subsets based on the expression level of CD25, GITR, and PD-1. Tregs expressing low amounts of CD25, GITR and PD-1 limit the development of colitis by promoting the conversion of conventional CD4 + T cells into pTreg. Tregs highly expressing CD25, GITR and PD-1 are more self ...
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.
CD25 deficiency or interleukin 2 receptor alpha deficiency is an immunodeficiency disorder associated with mutations in the interleukin 2 receptor alpha (CD25) (IL2RA) gene. The mutations cause expression of a defective α chain or complete absence thereof, an essential part of high-affinity interleukin-2 (IL-2) receptors.
These two serious health conditions occur when plaque forms in arteries, which can slow down blood flow in the body and cause small blood clots to form. Blocking or disrupting blood flow to the ...
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.
