The human receptor for interleukin-2 (T-cell growth factor) plays a critical role in the growth of T cells and is required for full expression of the normal immune response. Through hybridoma and recombinant DNA techniques, the interleukin-2 receptor protein has been biochemically characterized and purified; full-length copies of its complementary DNA have been molecularly cloned, sequenced, and expressed in eukaryotic cells; and the receptor gene has been characterized. Transient expression of the interleukin-2 receptor gene occurs during normal T-cell activation, and high- and low-affinity forms of the membrane receptor exist. A naturally occurring, soluble receptor has also been isolated, and its levels in serum correlate with the activity of various diseases. Deregulation of interleukin-2 receptor expression occurs in T-cell leukemias produced by the human T-lymphotropic retroviruses types l and ll (HTLV-l and -ll) and has been causally linked to the action of the trans-activator (tat) gene of these viruses. Monoclonal antibodies specific for the interleukin-2 receptor are being evaluated in the treatment of HTLV-l-induced leukemias and other conditions involving the inappropriate function of activated T cells.
