Self-assembling peptides incorporating modifications and methods of use thereof

The invention provides a self-assembling peptide comprising (a) a first amino acid domain that mediates self-assembly, wherein the domain comprises alternating hydrophobic and hydrophilic amino acids that are complementary and structurally compatible and self-assemble into a macroscopic structure when present in unmodified form; and (b) a second amino acid domain that does not self-assemble in isolated form. In certain embodiments of the invention the second amino acid domain comprises a biologically active peptide motif, e.g., a peptide motif found in a naturally occurring protein, or a target site for an interaction with a biomolecule. In certain embodiments of the invention the naturally occurring protein is a component of the extracellular matrix, e.g., a component of the basement membrane. The invention further provides scaffolds comprising the self-assembling peptides and methods of using the scaffolds including for cell culture, tissue engineering, and tissue repair.

Stabilized bioactive peptides and methods of identification, synthesis, and use

InactiveUS20060099571A1Slow down rate of intracellular degradationBacteriaPeptide/protein ingredientsLac operonΑ helical
An intracellular selection system allows screening for peptide bioactivity and stability. Randomized recombinant peptides are screened for bioactivity in a tightly regulated expression system, preferably derived from the wild-type lac operon. Bioactive peptides thus identified are inherently protease- and peptidase-resistant. Also provided are bioactive peptides stabilized by a stabilizing group at the N-terminus, the C-terminus, or both. The stabilizing group can be a small stable protein, such as the Rop protein, glutathione sulfotransferase, thioredoxin, maltose binding protein, or glutathione reductase, an α-helical moiety, or one or more proline residues.

Bioactive peptides and unique ires elements from myelin proteolipid protein plp/dm20

Three novel low molecular weight (LMW) polypeptide fragments of a proteolipid protein human PLP / DM20 are designated PIRP-M, PIRP-L and PIRP-J, and are growth factors for oligodendrocytes with anti-apoptotic activity. They are encoded by mRNA from an IRES. Fusion polypeptides of such a LMW polypeptide, DNA encoding the LMW polypeptide and fusion polypeptide, expression vectors comprising such DNA, and cells expressing such polypeptides, or pharmaceutical compositions thereof, are useful for stimulating neural stem cell differentiation, maturation along the oligodendrocytic pathway and proliferation of oligodendrocytes or precursors. These compositions can protect oligodendrocytes (and nonneural cells) from apoptotic death. Thus, the present composition is used to treat a disease or condition in which such differentiation, maturation and proliferation or inhibition of cell death, including remyelination or stimulation of oligodendroglia or Schwann cells, is desirable. Disorders include multiple sclerosis, trauma with Parkinson's-like symptoms, hypoxic ischerriia and spinal cord trauma.
