Scientific Background :IL-2 or interleukin 2 is a secreted cytokine which referred to as T-cell growth factor, that is a powerfully immunoregulatory lymphokine that is produced by lectin- or antigen-activated T cells. IL2 can act as a growth hormone that is important for the proliferation of T and B-lymphocytes (1). IL2 expression is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene (2).
