摘要:
Novel polypeptides and methods of making and using the same are described herein. The polypeptides include cross-linking ("hydrocarbon stapling") moieties to provide a tether between two amino acid moieties, which constrains the secondary structure of the polypeptide. The polypeptides described herein can be used to treat diseases characterized by excessive or inadequate cellular death.
摘要:
The present invention is directed to the use of DMSO for the stabilization of temperature sensitive peptides, namely gastrin and gastrin related peptides, against degradation in a mammalian biological sample, such as a serum or plasma sample.
摘要:
The present invention provides novel peptides, nucleic acids, compounds, compositions and methods for regulating apoptosis, and screening methods for identifying same. Regulation of apoptosis is mediated via IAPi-derived proteins, peptide fragments thereof, and nucleic acids encoding same, stimulating/accelerating or downmodulating/suppressing apoptosis. For stimulation/acceleration of apoptosis, the IAPi-derived proteins or peptide fragments thereof comprise RHG and Trp-box amino acid consensus sequences. Stimulation/acceleration results in self-ubiquitination and auto-degradation of an IAP. For downmodulation/suppression of apoptosis, IAPi-derived proteins or peptide fragments thereof comprising either RHG or Trp-box amino acid consensus sequences, or both, failing to stimulate or suppressing self-ubiquitination and auto-degradation of an IAP, result in suppression of apoptosis.
摘要:
The present invention provides fibroblast growth factor variants demonstrating enhanced receptor subtype specificity and/or affinity. Preferred embodiments include both variants having enhanced activity that act as improved agonists and variants having reduced activity that act as antagonists. Methods of utilizing preferred FGF variants in preparation of medicaments for the treatment of skeletal disorders including skeletal dysplasia, osteoporosis and enhancing bone fracture healing and cartilage healing processes are provided.

摘要:
Protein structural determination using NMR techniques is improved through use of proteins in which one or more amino acids in the peptidic sequence are isotopically enriched in the sidechain with 2H and are isotopically enriched on the backbone with 13C, 15N, 2H or any combination thereof. This invention provides amino acids isotopically enriched as above, which can be used to synthesize isotopically labeled proteins and peptides for protein structural determinations by NMR, and methods for their synthesis. Other embodiments of the invention include peptidic molecules, media for peptidic molecule expression, methods of making isotopically labeled peptidic molecules and methods of determining structural information of a peptidic molecule.
摘要:
The present invention is based on the discovery that MHC monomers immobilized to a solid surface are capable of activating T-cells that recognize specific peptides in the context of MHC Class I or Class II molecules. Methods for detecting T-cells responding to MHC monomers, and methods for measuring the frequency of specific and activated T-cells in a heterogeneous population are provided. The present invention also provides systems and kits useful for conducting the methods of the present invention.
摘要:
The present invention relates to antibodies and antigen-binding portions thereof that specifically bind to CD40, preferably human CD40, and that function as CD40 agonists. The invention also relates to human anti-CD40 antibodies and antigen-binding portions thereof. The invention also relates to antibodies that are chimeric, bispecific, derivatized, single chain antibodies or portions of fusion proteins. The invention also relates to isolated heavy and light chain immunoglobulins derived from human anti-CD40 antibodies and nucleic acid molecules encoding such immunoglobulins. The present invention also relates to methods of making human anti-CD40 antibodies, compositions comprising these antibodies and methods of using the antibodies and compositions for diagnosis and treatment. The invention also provides gene therapy methods using nucleic acid molecules encoding the heavy and/or light immunoglobulin molecules that comprise the human anti-CD40 antibodies. The invention also relates to transgenic animals comprising nucleic acid molecules of the present invention.
