T regulatory cells control T‐cell proliferation partly by the release of soluble CD25 in patients with B‐cell malignancies

Abstract excerpt

Interleukin-2 (IL-2) is one of the most studied cytokines driving T-cell proliferation, activation and survival. It binds to the IL-2 receptor consisting of three chains, the α (CD25), β and common γ (γc). The binding of the CD25 chain to IL-2 is necessary to expose high-affinity binding sites for the β and γc chains, which, in turn, are responsible for downstream signalling. A high level of soluble CD25 (sCD25)...
