Patent ID: 7906123

Claim:
A polypeptide capable of binding to CD11b/CD18, said polypeptide consisting of either a. a fragment of a Bordetella adenylate cyclase having from 30 to 500 amino acids, said fragment comprising the wild-type CD11b/CD18 interaction domain of the Bordetella adenylate cyclase, corresponding to amino acid 1166 to amino acid 1281 of SEQ ID NO:1 or SEQ ID NO:3, or comprising a fragment of the wild-type CD11b/CD18 interaction domain sufficient to retain the capacity to bind to CD11b/CD18, or b. a variant of said fragment of a Bordetella adenylate cyclase, having at least 70% identity with said fragment, wherein said variant retains the capacity to bind to CD11b/CD18.
