The present invention concerns methods and compositions for stably tethered structures of defined compositions, which may have multiple functionalities and/or binding specificities. Particular embodiments concern homodimers comprising monomers that contain a dimerization and docking domain attached to a precursor. The precursors may be virtually any molecule or structure, such as antibodies, antibody fragments, antibody analogs or mimetics, aptamers, binding peptides, fragments of binding proteins, known ligands for proteins or other molecules, enzymes, detectable labels or tags, therapeutic agents, toxins, pharmaceuticals, cytokines, interleukins, interferons, radioisotopes, proteins, peptides, peptide mimetics, polynucleotides, RNAi, oligosaccharides, natural or synthetic polymeric substances, nanoparticles, quantum dots, organic or inorganic compounds, etc. Other embodiments concern tetramers comprising a first and second homodimer, which may be identical or different. The disclosed methods and compositions provide a facile and general way to obtain homodimers, homotetramers and heterotetramers of virtually any functionality and/or binding specificity.

The present invention provides peptide analogs and peptide mimetics that inhibit pleated sheet formation in amyloid beta-peptide, pharmaceutical compositions thereof and their therapeutic use. The inhibitory peptides possess activity as inhibitors in the formation of amyloid-like deposits and are useful in the treatment of Alzheimer's Disease.

The present invention relates to an influenza antigen, comprising a fusion product of at least the extracellular part of a conserved influenza membrane protein or a functional fragment thereof and a presenting carrier, which may be a presenting (poly)peptide or a non-peptidic structure, such as glycans, peptide mimetics, synthetic polymers. The invention further relates to a vaccine against influenza, comprising at least an antigen of the invention, optionally in the presence of one or more excipients. The invention also relates to use of the antigen, a method for preparing the antigen and acceptor cells expressing the antigen.

This invention provides novel active agents (e.g. peptides, small organic molecules, amino acid pairs, etc.) peptides that ameliorate one or more symptoms of atherosclerosis and/or other pathologies characterized by an inflammatory response. In certain embodiment, the peptides resemble a G* amphipathic helix of apolipoprotein J. The agents are highly stable and readily administered via an oral route.

Novel bactericidal antibodies against Neisseria meningitidis serogroup B (“MenB”) are disclosed. The antibodies either do not cross-react or minimally cross-react with host tissue polysialic acid and hence pose minimal risk of autoimmune activity. The antibodies are used to identify molecular mimetics of unique epitopes found on MenB or E. coli K1. Examples of such peptide mimetics are described that elicit serum antibody capable of activating complement-mediated bacteriolysis of MenB. Vaccine compositions containing such mimetics can be used to prevent MenB or E. coli K1 disease without the risk of evoking autoantibody.

Short peptide mimetics of adiponectin suitable for development as pharmaceutical agonists in the treatment of cellular proliferative disorders such as cancer and atherosclerosis are provided.

The present invention relates to dual incretin peptide mimetic compounds that agonize receptors for both human glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), and may be useful for treating type 2 diabetes mellitus (T2D).

The present invention includes peptides, compositions as well as their use for the prevention or treatment of various age related or pathological conditions of skin or other tissues including skin wrinkles, wounds, different types of fibrosis and methods of reconstructing different tissues such as techniques used in regenerative medicine. The invention further includes peptide mimetics and methods of use including interfering with transcriptional complexes characteristic of fibroblasts of aged skin and stimulating synthesis of structural components of extracellular matrix.

Provided are compositions and methods for treating survivin expressing cancers. The compositions contain peptide survivin peptide mimics with improved MHC-I binding characteristics. The method involves administering a survivin peptide mimic with improved MHC-I binding characteristics to an individual to effect inhibition of the growth of survivin expressing cancer cells in the individual.

This invention relates to NAP-like and SAL-like peptide mimetics, polypeptides, or small molecules derived from them, and their use in the treatment of neuronal dysfunction, neurodegenerative disorders cognitive deficits, neuropsychiatric disorders, and autoimmune disease.

This invention provides novel active agents (e.g. peptides, small organic molecules, amino acid pairs, etc.) peptides that ameliorate one or more symptoms of atherosclerosis and/or other pathologies characterized by an inflammatory response. In certain embodiment, the peptides resemble a G* amphipathic helix of apolipoprotein J. The agents are highly stable and readily administered via an oral route.

Y receptor agonists which are selective for Y2 and Y4 receptors over the Y1 receptor are useful for treatment of, for example obesity, are (a) PP-fold peptides or PP-fold peptides mimics which have (i) a C-terminal Y receptor-recognition amino acid sequence represented by —X-Thr-Arg-X³-Arg-Tyr-C(=0)NR¹R² wherein R¹ and R¹ are independently hydrogen or C₁-C₆ alkyl X is Val, Ile, Leu or Ala, and X³ is Gln or Asn, or a conservatively substituted variant thereof in which Thr is replaced by His or Asn and/or Tyr is replaced by Trp or Phe; and/or Arg is replaced by Lys, and (ii) an N-terminal Y receptor-recognition amino acid sequence represented by H₂N—X¹-Pro-X²—(Glu or Asp)—wherein X¹ is not present or is amino acid residue, and X² is Leu or Ser or conservative substitutions of Leu or Ser, or (b) the said comprise a C-terminal Y receptor-recognition amino acid sequence as defined in (i) above, said Y receptor-recognition sequence being fused to an amphiphilic amino acid sequence domain comprising at least one alpha helical turn adjacent the N-terminus of the said hexapeptide sequence, said turn being constrained in a helical configuration by a covalent intramolecular link, and optionally an N-terminal sequence which commences with a Y receptor-recognition amino acid sequence as defined in (ii) above.
