**Semantic type:** Gene or Genome

**Definition:** Interleukin Genes encode Interleukins, soluble cytokine factors produced by leukocytes and other cell types that have broad functional activities, particularly in regulating the inflammatory and immune responses of a variety of cell types. Interleukins enhance cell proliferation and differentiation, DNA synthesis, secretion of other biologically active molecules, and responses to immune and inflammatory stimuli. (NCI)
