title: Cytotoxic activity of an interleukin 2-Pseudomonas exotoxin chimeric protein produced in Escherichia coli.
abstract: A cDNA clone for human interleukin 2 (IL-2) has been fused to the 5' end of a modified Pseudomonas exotoxin (PE) gene that lacks the sequences encoding the cell recognition domain. The chimeric protein IL-2-PE40 was produced in Escherichia coli. It was extremely toxic to IL-2 receptor-positive cells but had no measurable effect on cells lacking the IL-2 receptor. IL-2-PE40 might be a useful cytotoxic agent in the treatment of diseases involving IL-2 receptor-positive cells and in the treatment of allograft rejection.
