Actions biochimiques/physiologiques
IL-21 (interleukin-21) belongs to the IL-2 cytokine family. It is secreted by CD4+ T, natural killer (NK) and Th17 cells. IL-21 associates with IL-21 receptor and participates in B-cell proliferation, differentiation as well as apoptosis. It also promotes the cytotoxic activity of CD8+ T cells and natural killer cells.IL-21 plays a crucial role in the differentiation of follicular helper T cells. It also exhibits antitumor activity.[1][2] It is also involved in the activation of JAK-STAT (Janus kinase - signal transducer and activator of transcription), PI3K (phosphatidylinositol 3-kinase) and MAPK (mitogen activated protein kinase) pathways.[3]
IL-21 and its receptor have important roles in T and B cell proliferation and natural killer cell maturation.
IL-21 and its receptor have important roles in T and B cell proliferation and natural killer cell maturation. Human and mouse IL-21 share 57% amino acid identity.
Forme physique
Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline containing 0.5 mg bovine serum albumin.
Remarque sur l'analyse
The biological activity is measured by its ability to induce proliferation of human N1186 T cells.

Antigen-specific monoclonal antibodies isolated from B cells expressing constitutively active STAT5.
Ferenc A Scheeren et al.
PloS one, 6(4), e17189-e17189 (2011-04-29)
Fully human monoclonal antibodies directed against specific pathogens have a high therapeutic potential, but are difficult to generate. Memory B cells were immortalized by expressing an inducible active mutant of the transcription factor Signal Transducer and Activator of Transcription 5

The B cell lymphoma-6 (Bcl-6) and Bcl-xL proteins are expressed in germinal center B cells and enable them to endure the proliferative and mutagenic environment of the germinal center. By introducing these genes into peripheral blood memory B cells and

IL-21 is a type I cytokine essential for immune cell differentiation and function. Although IL-21 can activate several STAT family transcription factors, previous studies focused mainly on the role of STAT3 in IL-21 signaling. Here, we investigated the role of

Mantle cell lymphoma (MCL) is a distinct subtype of non-Hodgkin lymphoma characterized by overexpression of cyclin D1 in 95% of patients. MCL patients experience frequent relapses resulting in median survival of 3 to 5 years, requiring more efficient therapeutic regimens.
Pablo D Becker et al.
PloS one, 5(10) (2010-10-20)
Passive transfer of antibodies not only provides immediate short-term protection against disease, but also can be exploited as a therapeutic tool. However, the 'humanization' of murine monoclonal antibodies (mAbs) is a time-consuming and expensive process that has the inherent drawback
