The present invention relates to a probiotic cell transformed with a construct suitable to overexpress and display on the surface of the probiotic cell a fusion protein comprising at least a portion of a transport protein coupled to at least a portion of one or more antigenic proteins or peptides. Probiotic-derived vesicles displaying this fusion protein as well as methods of inducing an immune response using the probiotic cells or vesicles are also disclosed.

[Problem] The present invention addresses the problem of providing an anti-Staphylococcus antibody having preventive or therapeutic effects on staphylococcal infections. [Solution] Provided is an anti-Staphylococcus antibody having preventive or therapeutic effects on staphylococcal infections and a method for manufacturing said antibody, as well as a composition, a product, and a drug containing said antibody. The antibody is obtained by using deacetylated Staphylococcus for immunization.

The present invention discloses a hypericin albumin nanoparticle-Escherichia coli serum antibody complex, which is obtained through adding mixed hypericin albumin nanoparticles and rabbit anti-Escherichia colis into ethanediol, irradiating them with carbon ion, setting them at a low temperature for 2 hours after irradiation, centrifuging them at a low temperature, and freezing and drying the precipitates. Its preparation method and application are also provided. The beneficial effects of the present invention are as follows: the present invention provides a hypericin albumin nanoparticle-Escherichia coli serum antibody complex and its preparation method and application, wherein through bacteriostatic test and clinical pharmacodynamic test, it is proved that the effects of target complex is greatly improved compared with that of the prior drug, because the Escherichia coli serum antibodies seek and capture Escherichia coli and the hypericin albumin nanoparticles inhibit and kill Escherichia coli, which precisely attacks Escherichia coli and strengthen the antibacterial effect of hypericin albumin nanoparticle on chicken focus location.

The invention provides compositions (e.g., peptide compositions) useful for the detection of antibodies that bind to Borrelia antigens. The peptide compositions comprise polypeptide sequences comprising variants in the IR6 domain of the Borrelia VlsE protein. The invention also provides devices, methods, and kits comprising such peptide compositions and useful for the detection of antibodies that bind to Borrelia antigens and the diagnosis of Lyme disease.

The disclosure relates to therapeutic proteins and pharmaceutical compositions comprising said proteins, which have utility in treating various human diseases. In particular aspects, the disclosed therapeutic proteins are useful for treating human gastrointestinal inflammatory diseases and gastrointestinal conditions associated with decreased epithelial cell barrier function or integrity. Further, the disclosed therapeutic proteins are useful for treating human inflammatory bowel disease, including inter alia, Crohn's disease and ulcerative colitis.

Methods for diagnosing or treating immune disorders in a subject are provided. The methods are based on the detection or modulation of Refractory state Inducing Factor (RIF).

Methods for diagnosing or treating immune disorders in a subject are provided. The methods are based on the detection or modulation of Refractory state Inducing Factor (RIF).

The present invention relates to the combination of spirulina and palmitoylethanolamide (PEA) and/or pharmaceutically acceptable derivates or salts thereof, pharmaceutical formulations comprising the combination of spirulina and PEA and/or pharmaceutically acceptable derivates or salts thereof, optionally together with at least one physiologically acceptable excipient, and the use of the combination of spirulina and PEA and/or pharmaceutically acceptable derivates or salts thereof and formulations which include the said combination, for use in the prevention and/or treatment of tissue hyperactivation states, in the prevention and/or treatment of inflammatory pathologies, in the prevention and/or treatment of alterations in cardiac and/or coronary tissue, in the prevention and/or treatment of alterations in the vascular tissue, in the prevention and/or treatment of ophthalmic pathologies, preferably in the prevention and/or treatment of macular degeneration pathologies and glaucoma, in the prevention and/or treatment of dyslipidemia, in the prevention and/or treatment of alterations in pulmonary tissue, in the prevention and/or treatment of alterations in pelvic tissues, in the prevention and/or treatment of cellular alterations due to carcinogenesis, and/or in the prevention and/or treatment of dermatological alterations.

Provided herein are HER2-targeting molecules comprising Shiga toxin A Subunit derived polypeptides having 1) de-immunization and 2) reduced, protease-cleavage sensitivity while retaining Shiga toxin function(s), such as, e.g., potent cytotoxicity via ribosome inhibition. Certain HER2-targeting molecules of the present invention exhibit reduced immunogenic potential in mammals and are well-tolerated by mammals while retaining aforementioned features. The HER2-targeting molecules of the present invention have uses for selectively killing specific cells (e.g., HER positive tumor cells); for selectively delivering cargos to specific cells (e.g., HER positive tumor cells), and as therapeutic and/or diagnostic molecules for treating and diagnosing a variety of conditions, including cancers and tumors involving the expression or over-expression of cell-surface HER2.

This disclosure relates to materials and methods useful for vaccinating mammals against the effects of envenomation by venomous organisms (including the Western Rattlesnake) by making use of venom from multiple distinct populations, subspecies or species of the organism, to make a vaccine more broadly protective against other populations, subspecies or species.
