IL-15 is 14-15kD, a member of the four alpha-helical bundle family of cytokines. It is very similar to IL-2, except that IL-15 has a IL-15 alpha receptor subunit. It plays an important role in the growth and differentiation of T and B lymphocytes, natural killer cells, macrophages, and monocytes as well as it...

IL-15 is a member of the four helix-bundle cytokine family with a molecular weight of 14-15 kD. Its in vitro activity is very similar to that of IL2, except that IL-15 utilizes the IL-15 receptor alpha subunit for binding. IL15 play an important role in the growth and differentiation of T and B lymphocytes, natural...

IL28 is a cytokine distantly related to type I interferons and the IL-10 family. This gene, interleukin 28B (IL28B), and interleukin 29 (IL29) are three closely related cytokine genes that form a cytokine gene cluster on a chromosomal region mapped to 19q13. Expression of the cytokines encoded by the three genes can...
