Abstract
This invention relates to the fields of immunology and protein therapeutics. The therapeutic proteins are polypeptides to be administered especially to humans. The polypeptides are modified whereby the modification results in a reduced propensity for the polypeptide to elicit an immune response upon administration to the human subject. The invention therefor provides methods for the development of therapeutic polypeptides that are less immunogenic than any non-modified counterpart when used in vivo. The modifications used according to this invention relate, for example, to the introduction of protease cleavage sites, attachment of different molecules or insertion of non-natural amino acids.
