Biochem/physiol Actions

Interleukin-2 (IL-2), a cytokine, enhances Th (T helper) cell differentiation and effector responses. In addition, it helps in immune tolerance. IL-2 binds to the high affinity receptor, formed of IL2RA (interleukin 2 receptor subunit α), IL2RB (interleukin 2 receptor subunit β) and γ-chain. Polymorphism in IL2RA is associated with multiple sclerosis. Null mutation in IL2RA results in immune dysregulation.

Physical form

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline containing 0.25 mg bovine serum albumin.

Analysis Note

The bioactivity is measured by its ability to inhibit the IL-2-dependent proliferation of a human megakaryocytic leukemic cell line, M07e.

Cell-surface CD25 expression is critical for maintaining immune function and homeostasis. As in few reported cases, CD25 deficiency manifests with severe autoimmune enteritis and viral infections. To dissect the underlying immunological mechanisms driving these symptoms, we analyzed the regulatory and

A new human leukaemic cell line (M-O7) with the phenotypic characteristics of CFU-mega is described. Its cells are positive for T200 leucocyte common antigen (LCA) and negative with MAbs recognizing T and B cells and mature myelomonocytic antigens. In contrast

Genome-wide association studies implicate dysregulation of immune mechanisms in the pathogenesis of multiple sclerosis (MS). Particularly, polymorphisms in genes involved in T helper (TH) cell differentiation are associated with risk of developing MS. However, the underlying mechanism by which these
