Kh. Grabstein et al., CLONING OF A T-CELL GROWTH-FACTOR THAT INTERACTS WITH THE BETA-CHAIN OF THE INTERLEUKIN-2 RECEPTOR, Science, 264(5161), 1994, pp. 965-968
A cytokine was identified that stimulated the proliferation of T lymph
ocytes, and a complementary DNA clone encoding this new T cell growth
factor was isolated. The cytokine, designated interleukin-15 (IL-15),
is produced by a wide variety of cells and tissues and shares many bio
logical properties with IL-2. Monoclonal antibodies to the beta chain
of the IL-2 receptor inhibited the biological activity of IL-15, and I
L-15 competed for binding with IL-2, indicating that IL-15 uses compon
ents of the IL-2 receptor.
