Image Number 11 for United States Patent #6653282.
Peptide compositions which inhibit the binding of one protein to another protein, and corresponding methods of use are disclosed. These peptide compositions include at least one peptide which binds to one protein, and at least one peptide which binds to the other protein. In the preferred embodiment, the peptide composition is composed of a combination of cyclic ICAM-1-based and LFA-1-based peptides which inhibit the binding of LFA-1 to ICAM-1. Such LFA-1/ICAM-1-based peptide compositions can be used to treat disease states such as rejection of transplanted organs, allergies, and autoimmune diseases.
