Abstract

Human interleukin-18 (IL-18) polypeptides and substitution mutants thereof were conjugated to water-soluble polymers at specific sites on the human IL-18 protein.

These conjugated cytokines demonstrate enhanced and unexpected biological properties when compared to the corresponding unconjugated cytokines.
