Název v původním jazyce

Increasing the biological activity of IL-2 and IL-15 through complexing with anti-IL-2 mAbs and Il-15Ralfa-Fc chimera

Popis výsledku v původním jazyce

IL-2 and IL-15 are structurally relative cytokines that share two receptor subunits, CD132 (-y, chain) and CD122 (beta chain). However, the expression pattern and physiological role of IL-2 and IL-15 private receptor a chains CD25 and IL-15Ra, respectively, are strikingly different. CD25, together with CD122 and CD132, forms a trimeric high affinity IL-2 receptor that is expressed and functions on cells acquiring an IL-2 signal. Conversely, IL-15Ra is expressed and binds IL-15 with high affinity per sealready in the endoplasmic reticulum of the IL-15 producing cells and it presents IL-15 to cells expressing CD122/CD132 dimeric receptor in trans. Thus, while IL-2 is secreted almost exclusively by activated T cells and acts as a free molecule, IL-15 isexpressed mostly by myeloid cells and works as a cell surface-associated cytokine. Interestingly, the in vivo biological activity of IL-2 can be dramatically increased through complexing with certain anti-IL-2 itiAbs; such IL-2/anti-IL-2
