Description
Interleukin-15 (IL-15) is an immunomodulating cytokine that stimulated the proliferation of T lymphocytes. It shares many biological properties with IL-2. IL-5 is a potent lymphoid cell growth factor that exerts its biological activities primarily on T cells. It is essential in the development, survival and activation of NK cells. Increased expression of IL-15 has been implicated with rheumatoid arthritis, imflammatory bowl disease and diseases affiliated with retroviruses HIV and HTLV-I. Human IL-15 is a 12.9 kD protein containing 114 amino acid residues
