ABSTRACT:
Disclosed are novel muteins of IL-1 compounds which can be used to regulate excess IL-1 produced in various diseases in humans and animals. The IL-1 muteins can be prepared by site-directed mutagenesis whereby a positively charged residue is replaced with a negatively charged or neutral residue at a designated position in the molecule. The resulting IL-1 muteins have reduced biological activity but retain receptor binding affinity.
