Abstract

The invention provides cytokine fusion proteins with an increased therapeutic index, and methods to increase the therapeutic index of such fusion proteins. The fusion proteins of the invention are able to bind to more than one type of cytokine receptor expressed on cells and also bind to more than one cell type. In addition, the fusion proteins of the invention exhibit a longer circulating half-life in a patient's body than the corresponding naturally occurring cytokine.
