The present invention relates to a biodegradable nanocomplex. The biodegradable nanocomplex comprises a first electrically charged substance, a charge-redistribution substance, a second electrically charged substance and a carried substance, for holding the carried substance inside. The first electrically charged substance and the carried substance have the same electrical polarity, and the biodegradable nanocomplex has a nonuniformally and positively charge distribution along a radial direction thereof. The nonuniformally and positively charge distribution comprises a first electrically charged portion having substantially electrical neutrality, a second electrically charged portion surrounding the first electrically charged portion, and a third electrically charged portion surrounding the second electrically charged portion, in which the third electrically charged portion comprises an outermost surface of the biodegradable nanocomplex, thereby modulating the carried substance towards the desired immune responses via the nonuniformally and positively charge distribution.

Disclosed herein is a personalized tumor vaccine comprising attenuated cancer cells and a method of using said personalized tumor vaccine to treat cancer.

Compositions are provided comprising a pro-reparative factor such as a colostrum, a nutritional protease inhibitor to decrease enzymatic digestion of the pro-reparative factors, and optionally a stabilizing agent, to allow the pro-reparative factors to reach the small intestine intact following oral administration. Methods are provided for treating, alleviating, and preventing inflammatory bowel disease (IBD) and other disorders of the gastrointestinal tract.

Compositions and methods are described for inducing an immune response against extra-intestinal pathogenic Escherichia coli (ExPEC) to thereby provide immune protection against diseases associated with ExPEC. In particular, compositions and methods are described for using conjugates of E. coli polysaccharide antigens O25B, O1A, O2, and O6A covalently bound to a detoxified exotoxin A of Pseudomonas aeruginosa (EPA) carrier protein as vaccines for the prevention of invasive ExPEC disease caused by ExPEC serotypes O1A, O2, O6A and O25B.

The present invention relates to an immunogenic complex comprising an amino acid sequence having at least 80% sequence identity with the amino acid sequence of the N-terminal region of a group B Streptococcus surface protein, and a capsular polysaccharide. The immunogenic complex is capable of eliciting protective immunity against group B Streptococcus. The invention further pertains to an immunogenic product comprising the immunogenic complex and an immunogenic fusion protein, the vaccine, the immunogenic complex, or the immunogenic product for use in a method of preventing or treating a group B Streptococcus infection, as well as a method of preventing or treating a group B Streptococcus infection.

Monomers and copolymers are provided that both target antigen presenting cells (APCs) and activate toll-like receptor (TLR) on the APCs. In some embodiments, compositions and methods involve a polymer that targets the mannose receptor on APCs, in addition to activating a TLR. These can then be conjugated to protein antigens to efficiently target antigens to DCs and simultaneously induce the up-regulation of co-stimulatory molecules that are essential for effective T cell activation. This copolymer is a more efficient activator of DCs, as measured by the surface expression of co-stimulatory molecules and the release of proinflammatory cytokines, than the monomeric form the TLR agonist used in the polymer formulation. Aspects of the disclosure relate to novel compounds, methods, and compositions for treating diseases using the compounds, copolymers, and compositions described herein.

This invention relates generally to compositions and methods for increasing the efficacy of immunotherapies and vaccines. In particular, the present invention relates to elevating the richness and diversity of a subject's gut microbiome through administration of an agent (e.g., fiber containing prebiotic agent (e.g., epigallocatechin gallate (EGCG), fucoidan, potato starch, oligofructose and inulin)) (e.g., melatonin) with an immunotherapy or vaccine. Such compositions and methods are useful for treating cancer, infectious pathogens, autoimmune diseases, neurological disorders, and/or obesity.

Technologies for the prevention and/or treatment of pneumococcal infections.

Provided herein are anti-Anti-Miillerian Hormone Receptor 2 (AMHR2) antibodies and methods of using such antibodies, for example, in the treatment of cancer.

The present disclosure provides a process for assaying stability of monovalent and/or multivalent, liquid and lyophilized polysaccharide protein conjugate vaccine compositions using HPLC-SEC method. The method provides stability analysis (lot to lot) of polysaccharide protein conjugate vaccine with respect to aggregation profile, molar mass distribution and/or molecular size distribution, and data can be utilized for quality control during storage and batch release. The method is performed in the presence of multiple carrier proteins, free polysaccharides and excipient, without any interference of said components.
