The present invention provides compositions and methods for treating a measles virus infection. A pharmaceutical composition comprises a polypeptide in a biocompatible pharmaceutical carrier, in which the polypeptide consists of at least a portion of SEQ ID NO: 5 or SEQ ID NO: 6. A method embodiment comprises administering the polypeptide (preferably in a biocompatible pharmaceutical carrier) to a subject suffering from a measles infection.

[Problem to be Solved] It is intended to provide a composition for hemostasis which can be uniformly applied to a bleeding site and exerts a high hemostatic effect.

[Solution] The present invention provides a composition to be applied as a spray to a subject, the spray being used for hemostasis, and the composition comprising a self-assembling peptide, wherein the self-assembling peptide self-assembles and thereby gels when the composition is applied to a bleeding site of the subject, and the self-assembling peptide is contained in the composition at a concentration at which the composition has an improved hemostatic ability as compared with that when directly applied.

Provided are a synthetic peptide having a multinucleation-inducing activity that can cause multinucleation in a target cell, a multinucleation-inducing agent containing this peptide, and a multinucleation induction method that uses this peptide, The synthetic peptide provided by the present invention is an artificially synthesized peptide that contains (A) a membrane-permeable peptide sequence and (B) a multinucleation-inducing peptide sequence, and that can cause multinucleation in at least one type of eukaryotic cell of human origin Or non-human mammal origin. The multinucleation-inducing peptide sequence is constituted of an amino acid sequence given by SEQ ID NO: 1 or SEQ ID NO: 2 or a modified amino acid sequence therefrom.

In one aspect, the present invention provides, for example, an improved method for identifying an epitope on a protein, comprising the following steps: (A) contacting a major histocompatibility complex (MHC molecule)-expressing cell differentiated from a stem cell or a progenitor cell derived therefrom with a target protein; (B) isolating a complex of a peptide contained in the target protein and the MHC molecule from the MHC molecule-expressing cell; and (C) eluting the peptide from the complex and identifying the peptide.

The methods and compositions described herein relate, in part, to the generation of a synthetic degradation system in E. coli that provides tunable control of the protein level of targeted genes by using components of the Mesoplasma florum tmRNA system. Provided herein are degradation tag variants that permit independent control of both the initial level and inducible degradation rate of attached proteins.

A family of peptides with antioxidant and brightening activities is disclosed as well as cosmetic compositions having the peptides and cosmetic uses and methods of the peptides or cosmetic compositions.

Disclosed are immunomodulatory polypeptides that elicit an unusual induced cytokine profile, compositions comprising such polypeptides, compositions comprising antibodies that specifically bind to such polypeptides, and methods of using the same, including in cancer treatment, in the treatment of autoimmune diseases, in organ transplantation and for reducing graft rejection, for promoting fertility, and for identifying a neutrophil subset and/or other cellular subset including by flow cytometry. Pharmaceutical compositions and kits, and treatment methods are also disclosed.

A tumor-targeting peptide is disclosed. This tumor-targeting peptide comprises a typical motif with the general formula of: XX(Y/F) (D/E) (D/E) XX. The motif is selectively connected with 1-3 amino acids at the C-terminal and/or N-erminal. X represents any one of the twenty natural amino acids or the D type amino acids. The present invention also discloses that the peptide can not only target tumor vessels and tumor cells but also penetrate them and thus can be applied in tumor diagnosis and therapy.
