Abstract
Abstract The present invention relates to an IL-2 receptor γ chain molecule, a DNA-sequence encoding the IL-2 receptor γ chain molecule, a vector possessing said DNA-sequence, a cell transformed with said vector, a method for the production of an IL-2 receptor γ chain molecule by culturing of said cell, an immune response regulatory agent comprising an Il-2 receptor γ chain molecule and an antibody to an IL-2 receptor γ chain molecule. Both the Il-2 receptor γ chain molecule and the antibody to the IL-2 receptor γ chain molecule are very useful immune response regulatory agents.
