摘要:
The present invention provides peptide conjugates that target an integrin such as αvβ6 integrin. In particular embodiments, the peptide conjugates comprise a moiety such as a PEG moiety, an imaging agent, or a therapeutic agent. The peptide conjugates of the present invention are particularly useful for imaging a tumor, organ, or tissue. Compositions and kits containing the peptide conjugates of the present invention are also provided herein.

摘要:
Disclosed are treatment agents and methods of treatment utilizing the agents directed toward diseases in which the disease causing pathogen includes α6β1 integrin receptors and/or α6β4 integrin receptors on the surface of the pathogen. In one embodiment, the disease can be breast cancer. The therapeutic agents disclosed include a polypeptide comprising at least a portion of the G domain of the laminin-5 α3 chain that has been shown to bind α6β1 integrin receptors and α6β4 integrin receptors. In one embodiment, the therapeutic agents can be fused or chimeric materials in which the laminin-5 α3 chain polypeptide has been chemically bound to another material that can be useful in the destruction or neutralization of the pathogen.
摘要:
A method for the identification of a modulator of the interaction between latency associated peptide (LAP) of transforming growth factor null1 (TGF-null1) and the integrin avb3, which method comprises: (a) providing, as a first component, LAP-null1 or a functional variant thereof; (b) providing, as a second component, integrin avb3 or a functional variant thereof; (c) contacting the two components with a test product under conditions that, in the absence of the test product, would permit the two components to interact; and (d) determining whether the test product is capable of modulating the interaction between the first and second components, thereby to determine whether the test product is a modulator of the interaction between LAP-null1 and integrin avb3.
摘要:
A method for inhibiting pulmonary oxygen toxicity in a patient requiring elevated levels of inhaled oxygen, by prophylactic administration of certain adhesion molecules and antibodies thereto.
摘要:
A pharmaceutically acceptable aqueous gel composition comprising a gelling agent, magnesium and/or manganese, or bivalent ions thereof, and an mRNA molecule encoding a protein of interest; and methods for inducing or facilitating repair, re-generation or generation of tissue in a human or animal subject, comprising administering the composition to the site of the tissue to be repaired, re-generated or generated.
摘要:
A pharmaceutical composition includes a synthetic peptide consisting of about 10 to about 50 amino acids and having an amino acid sequence substantially homologous to consecutive amino acids of a portion of the cytoplasmic doman of at least one of αvβ3 integrin or VEGFR2 that includes a tyrosine residue, the amino acid sequence of the peptide including a phosphorylated tyrosine residue or a γ-carboxyglutamic acid residue that is substituted for a corresponding tyrosine residue of the portion of the cytoplasmic domain of αvβ3 integrin or VEGFR2.
摘要:
Described herein are modified integrin α and/or β headpiece polypeptides, and crystallizable integrin polypeptide dimers comprising a modified integrin α and/or β headpiece polypeptide and a disulfide bond linking the two integrin headpiece polypeptide subunits. Methods for using the modified integrin α and/or β headpiece polypeptides and the integrin polypeptide dimers are also provided herein. For example, methods for characterizing integrin-ligand interaction and identifying integrin ligands are also provided herein. In some embodiments, the identified integrin ligands can be used as inhibitors of integrins.
