Aspects of the disclosure relate to compositions and methods for eliciting (or enhancing) anti-repeat-associated non-ATG (RAN) protein antibody expression or production in a subject. Administration of the compositions according to the methods of the present disclosure may in some embodiments result in decreased levels of RAN protein expression and/or aggregation. Such compositions and methods may therefore be useful for the treatment of diseases and disorders known to be associated with RAN proteins.

The present disclosure relates to immunogenic compositions comprising a severe acute respiratory syndrome coron-avirus 2 (SARS-CoV-2) antigen, and a toll-like receptor 9 (TLR9) agonist, such as an oligonucleotide comprising an unmethylated cytidine-phospho-guanosine (CpG) motif. The immunogenic compositions are suitable for stimulating an immune response against a SARS-CoV-2 in an individual in need thereof.

The present invention relates to novel prime-boost regimens that involve the administration of at least one mRNA construct, such as the use of such constructs in “boost” administration subsequently to “prime” administration of certain other antigenic composition(s). Such inventive regimens may, in particular, be useful for the induction of an immune response in a subject, and/or the vaccination of such subject against infection from one or more pathogens, and/or the treatment or prevention of one or more diseases or conditions, including a tumour or cancer, allergy or autoimmune conditions, and/or a disease or condition associated with infection from a pathogen. The present invention further describes methods, uses, vaccination compositions, kits and packaged vaccine components related to or useful for one or more of such regimens

The present invention is intended to provide an adjuvant having high safety to living bodies and an action to sufficiently reinforce immune function, and a vaccine comprising the adjuvant. Specifically, the present invention relates to 34 novel adjuvant candidate compounds, which have been identified by screening 145 food additives and 51 injection additives, using, as indicators, an increase in the antibody titer against influenza virus and a protective effect against infection with influenza virus, and then selecting those having the function of increasing the antiviral antibody titer in blood and the protective effect against viral infection. In addition, the present invention also relates to a vaccine comprising these adjuvant candidate compounds.

The present disclosure provides a Farmington virus formulated to induce an immune response in a mammal against a tumour associated antigen. The Farmington virus may express an antigenic protein that includes an epitope from the tumour associated antigen. The Farmington virus may be formulated in a composition where the virus is separate from an antigenic protein that includes an epitope from the tumour associated antigen. The present disclosure also provides a prime:boost therapy for use in inducing an immune response in a mammal. The boost includes a Farmington virus, or a composition that includes a Farmington virus.

A novel composite, and research on the preparation, application and the like of the composite. The method for preparing the composite comprises: contacting a polyinosinic-polycytidylic acid, at least one cationic stabilizer, and a soluble calcium salt in a liquid reaction system, the cationic stabilizer being a water-soluble non-antibiotic amino compound having a molecular weight of less than or equal to 5 kDa, or a graft copolymer formed by a water-soluble non-antibiotic amino compound and one or more of methoxypolyethylene glycol, polyethylene glycol, polyethylenimine, folic acid, or galactose. The composite has moderate viscosity and molecular weight, is convenient to use in pharmaceutical application, has stable chemical properties, is not easy to be degraded in long-term storage, and is safe to use. The composite, if used alone, can significantly enhance the non-specific immune response of the body and achieve the purpose of preventing and treating diseases, and other drugs, and can achieve better anti-tumor, anti-viral and anti-(super) bacteria efficacy and is easily absorbed by patients, if used in combination with other drugs.

Disclosed herein is a non-covalent complex, comprising: a tetramer of a recombinant protein; and an agonist of a Stimulator of Interferon Gene (STING) protein or a pharmaceutically acceptable salt thereof, wherein the recombinant protein comprises a STING protein lacking a transmembrane domain (STINGΔTM protein). Additionally, provided is a vaccine composition, comprising a non-covalent complex and a pharmaceutically acceptable carrier, wherein the non-covalent complex comprises: a recombinant protein comprising a STINGΔTM protein and a tumor epitope; and an agonist of a STING protein or a pharmaceutically acceptable salt thereof. Further provided are methods of treating and preventing cancer using the disclosed complexes, pharmaceutical compositions, and vaccines.

A peptide vaccine complexed so that the peptide vaccine can be delivered specifically to the surface of specific immune cells and a method for delivering a peptide vaccine specifically to the surface of specific immune cells. The peptide vaccine is combined with an IgG binding peptide capable of binding to an IgG that is an agonist against molecules on the surface of specific immune cells such as dendritic cells.

Methods and compositions for diagnosing and vaccinating against Ehrlichia canis and Ehrlichia chaffeensis are provided.

The present invention relates to methods and compositions for treating human papilloma virus (HPV)-associated diseases using an inhibitor of CXCL12 signaling. The invention further relates to methods and compositions for treating immune checkpoint blockade resistant diseases using an inhibitor of CXCL12 signaling. The invention further relates to methods and compositions for enhancing the immune response against an HPV-associated disease using an inhibitor of CXCL12 signaling.
