X-linked severe combined immunodeficiency (XSCID) is characterized by absent or profoundly reduced numbers of T cells and normal numbers of B cells in the circulation. Affected patients have mutations of the interleukin-2 (IL-2) receptor gamma chain gene. Using Epstein-Barr virus-transformed B-lymphoblastoid cell lines (B-LCLs) established from two unrelated XSCID patients, we could show that neither expressed the IL-2 receptor gamma chain on the cell surface. A novel cytokine IL-15, which has biologic activities similar to those of IL-2, could bind to the XSCID B-LCLs in the absence of the gamma chain, although both the beta and gamma chains of the human IL-2 receptor were previously shown to be required for IL-15 binding by transfected COS cells. Furthermore, a significant reduction and delay of IL-15 internalization by B lymphoblasts from XSCID patients was observed when compared with that of normal control B-LCLs. These results show the existence of a novel IL-15-specific receptor component that contributes to IL-15 binding but is insufficient for IL-15 internalization in the absence of the IL-2 receptor gamma chain.
