A cytokine was identified that stimulated the proliferation of T lymphocytes, 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 biological properties with IL-2. Monoclonal antibodies to the β chain of the
IL-2 receptor inhibited the biological activity of IL-15, and IL-15 competed for binding with IL-
2, indicating that IL-15 uses components of the IL-2 receptor.
