COMPOSITIONS AND METHODS FOR TREATING ALZHEIMER'S DISEASE

摘要

The present disclosure provides for a hyperimmune preparation comprising human polyclonal antibodies or fragments thereof specific to a cyclic peptide having an amino acid sequence comprising SNK. The cyclic peptide may comprise an amino acid sequence GSNK (SEQ ID NO: 1), SNKG(SEQ ID NO: 2), GSNKG (SEQ ID N0:3), CSNKG (SEQ ID NO: 4), CGSNKGC (SEQ ID NO: 5), CGSNKGG (SEQ ID NO: 6), or CCGSNKGC (SEQ ID NO: 7). The antibodies in the hyperimmune preparation may have a titer ranging from about 200 to about 400 mean fluorescence intensity (MFI). In one embodiment, greater than about 80% of the antibodies in the hyperimmune preparation are IgG. The fragments of the antibodies are Fab, F(ab′)2, scFv, disulfide linked Fv, or mixtures thereof.
