Abstract: The present invention provides a method for stabilizing a protein in a desired conformation by introducing at least one disulfide bond into the polypeptide. Computational design is used to identify positions where cysteine residues can be introduced to form a disulfide bond in only one protein conformation, and therefore lock the protein in a given conformation. Accordingly, antibody and small molecule therapeutics are selected that are specific for the desired protein conformation.

Abstract: The invention concerns the use of functional derivatives of ICAM-1 to treat viral infection. The invention also provides a vaccine to prevent such infection, and a diagnostic assay to determine the existence and extent of such infection.

Abstract: The present invention relates to intercellular adhesion molecules (ICAM-1) which are involved in the process through which lymphocytes recognize and migrate to sites of inflammation as well as attach to cellular substrates during inflammation. The invention is directed toward such molecules, screening assays for identifying such molecules and antibodies capable of binding such molecules. The invention also includes uses for adhesion molecules and for the antibodies that are capable of binding them.

Abstract: The present invention is based on the novel observation that upon stimulation of resting myeloid cells, not all of the Mac-1 molecules expressed by the cell become activated. Only select subpopulations of Mac-1 molecules are activated and become capable of binding ligand. Further, the activated Mac-1 molecules were found to possess activation specific epitopes which distinguishes them from non-activated Mac-1 molecules. Based on these observations antibodies are described which selectively bind activated Mac-1 molecules but are substantially incapable of binding non-activated Mac-1.

Abstract: The present invention relates to a novel assay for lymphocyte chemotaxis. The assay is transendothelial assay using endothelial cells cultured on microporous filters. Lymphocyte transmigration through the filter toward a suspected chemoattractant is measured. Apparatuses for carrying out the assay are also provided. The apparatuses and methods of the present invention can be used for the identification of inhibitors (e.g., antagonists) or promoters (chemoattractants) of the adhesion receptor-mediated migration of leukocytes through the endothelium (extravasation). Such inhibitors and promoters respectively inhibit and promote the inflammatory response, and thus have therapeutic utilities. The inhibitors and promoters are identified by detecting their abilities to respectively inhibit or promote the chemotaxis of lymphocytes in the assay of the invention. The assay of the invention also has diagnostic utilities for detecting a disease or disorder involving a defect in lymphocyte chemotaxis.
