Scientific Background:Interleukin-2 (IL-2), also known as T-cell growth factor, plays a critical role in the mediation of immune response by acting as a growth and differentiation factor for T cells, B cells, natural killer (NK) cells, lymphokine-activated killer (LAK) cells, tumorinfiltrating lymphocytes (TIL), monocytes, macrophages, and oligodendrocytes. Before becoming biologically active, the protein undergoes extensive post-translational modification including cleavage, glycosylation and the formation of disulfide bonds. Portions of IL-2 are highly conserved across species in areas involved in receptor binding during activated complex formation. The human IL-2 receptor is composed of varying combinations of a 55 kDa IL-2Ra subunit, a 70-75 kDa IL-2Rβ subunit, and a 64 kDa IL- 2Rg subunit. IL-2 binding affinity varies depending on which combination of subunits is present in the bonding complex, with the high affinity binding site containing all three subunits. Studies show IL-2 causing the regression of some types of tumors, implying a role in immunotherapy and the treatment of infectious diseases and immune deficiencies.
