Abstract: The present invention relates to SAP-Fc fusion proteins comprising one or more amino acid substitution, for example, C226S and/or C229S. In some aspects, the fusion protein comprises a structure represented by the following formula, from N-terminus to C-terminus, SAP-Fc1-L1-Fc2, wherein Fc1 is a first Fc domain sequence comprising hinge-CH2-CH3, L1 is a linker, and Fc2 is a second Fc domain sequence comprising hinge-CH2-CH3. The present invention also relates to methods of treating amyloid related diseases by administering said SAP-Fc fusion proteins to a subject in need thereof.

Abstract: Immunoglobulin light chain proteins are used to generate synthetic fibrils in vitro. The fibrils are mixed with immunoglobulin light chain proteins from a biological sample. In either a direct binding assay, competition assay, or dilution-based competition assay, a signal is detected from the mixture. The intensity of the detectable signal relates to the level of binding between the immunoglobulin light chain proteins to the fibrils and can thus be used to identify amyloidogenic immunoglobulin light chain proteins in a biological sample of the subject and to assess amyloidogenic risk to a subject. For example, the signal intensities from the assays can be used in a comparison to one or more threshold (control) values derived from samples of known light chain types or in the absence of light chains. The comparisons permit identification of amyloidogenic proteins, assessment of amyloidogenic risk, and categorization of the subject into an appropriate “at risk” group.

Abstract: Disclosed are methods and compositions for targeting antibodies to amyloid deposits. For example, amyloid-reactive peptides that bind amyloid deposits are administered to a subject. Antibodies to the amyloid-reactive peptides are then administered to the subject. Upon administration of the antibodies, the amyloid-reactive peptides bind the antibodies and thus pre-target the antibodies to the amyloid deposits. In other examples, an amyloid-reactive fusion peptide contains an epitope of a known antibody. When the fusion peptide is administered to a subject, the fusion peptide binds amyloids in the subject. Administration to the subject of the known antibody that binds the epitope of the fusion peptide then targets the antibody to the amyloid deposit to which the fusion peptide is bound.

Abstract: Disclosed are methods of treating and/or inhibiting a viral infection in a subject. The methods include administering a therapeutically effective amount of heparin-binding peptide. Also disclosed herein are methods for blocking viral binding to a cell. Further disclosed are anti-viral compositions for administration to a subject infected with a virus. Administration of the anti-viral composition inhibits viral infection of the subject.
