Distinct IL2 Receptor Signaling Pattern in Laurence A. Turka Thompson, Matthew A. Burchill, Michael A. Farrar and Rapid Reviews! 30 days from submission to initial decision Negative regulation of phosphatidylinositol 3kinase signaling and IL2mediated proliferation of CD4 CD25 T cellsInterleukin2 (IL2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15, 5 16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. il-2 receptor signaling review

Nov 30, 2007  IL2R Signaling and Tregs. The IL2 receptorsignaling complex is composed of three distinct subunits, the chain (CD25), chain (CD122), and chain (CD132) each of which have unique roles in facilitating IL2dependent signal transduction.

Such studies established that IL2 sometimes contributes to optimal primary immune responses, but it is not mandatory. Also discussed are implications of this new appreciation concerning the immunobiology of IL2 with respect to targeting IL2 or its receptor in immunot 0. Institutional Login First published online as a Review in IL2 activation and signaling pathway. Interleukin2 ( IL2) is a TCellderived cytokine important in the regulation of growth and differentiation of TCells, BCells, natural killer cells, glioma cells, and cells of the monocyte lineage. IL2 signaling is mediated by a multichain IL2 receptor complex consisting of an alpha ( IL2R alpha chain), beta ( IL2R beta chain) and gamma ( IL2Ril-2 receptor signaling review IL2 receptor (IL2R or CD25 (NK) and lymphokineactivated killer cells, which mediate signaling and receptor internalization. The 55kDa IL2 (p55, Tac, or CD25) subunit, on the other hand, is expressed by most T, B, and NK cells only after they have been activated by interaction with an antigen or with IL2. IL2 receptors can be

The structure supports a model wherein IL2 initially binds to the chain, then the is recruited, and finally. Signaling. The three IL2 receptor chains span the cell membrane and extend into the cell, thereby delivering biochemical signals to the cell interior. il-2 receptor signaling review Interleukin2 receptor (IL2R) signaling regulates tolerance and immunity. Here, we review recent work concerning the structure, signaling, and function of the IL2R, emphasizing the contribution of IL2 for T celldependent activity in vivo. Herein, we discuss the molecular and cellular biology of IL2, its signaling mechanism, and its actions, as well as its relationship with the five other cytokines (IL4, IL7, IL9, IL15, and IL21) that share components of the IL2 receptor.

Aug 27, 2010 Interleukin2 receptor (IL2R) signaling regulates tolerance and immunity. Here, we review recent work concerning the structure, signaling, and function of the IL2R, emphasizing the contribution of IL2 for T celldependent activity in vivo.
