1. A method for inhibiting islet cell transplant rejection in a subject, comprising administering to the subject an effective amount of a CTLA4 molecule comprising a mutated extracellular domain comprising an amino acid sequence beginning with alanine at position 26 and ending with aspartic acid at position 150 as shown in SEQ ID NO:
- 6, or beginning with methionine at position 27 and ending with aspartic acid at position 150 as shown in SEQ ID NO;

Abstract
The present invention is a method of inhibiting islet cell transplant rejection, particularly to treat diabetes, such as type-1 and type-2 diabetes, by administering to a subject an effective amount of a soluble CTLA4 mutant molecule. One example of a soluble CTLA4 mutant molecule is L104EA29YIg.
