Interleukins are a type of cytokines that were first seen to be expressed by leukocytes. The term 'interleukin' describe a number of secreted molecules produced by leukocytes, a variety of polypeptides that act specifically as mediators between leucocytes. Interleukin (IL) has been used to describe a group of cytokines with complex immunomodulatory functions - including cell proliferation, maturation, migration and adhesion. These cytokines also play an important role in immune cell differentiation and activation. Determining the exact function of a particular cytokine is complicated by the influence of the producing cell type, the responding cell type and the phase of the immune response. Interleukins can also have pro- and anti-inflammatory effects, further complicating their characterisation. These molecules are under constant pressure to evolve due to continual competition between the host's immune system and infecting organisms; as such, Interleukins have undergone significant evolution. This has resulted in little amino acid conservation between orthologous proteins, which further complicates the gene family organisation.
