Aspects of the disclosure relate to methods for producing an antigen-specific immune response to human cytomegalovirus (hCMV) in a subject by administering mRNA vaccines.

The invention relates to a combination of a TLR-9 agonist and a conjugate of Formula (I) or pharmaceutically acceptable salt thereof. (Formula (I))

##STR00001##

The invention relates to compositions and methods for the preparation, manufacture and therapeutic use ribonucleic acid vaccines comprising polynucleotide molecules encoding one or more influenza antigens, such as hemagglutinin antigens.

The present invention relates to Toll-Like Receptor 2 (TLR2) agonists, in particular, to TLR2-activating lipoproteins, and more particularly to TLR2-activating lipopeptides derived from the bacteria Bordetella pertussis. The invention further extends to the use of said TLR2-activating lipoproteins as a therapeutic or as part of a vaccine composition in the treatment and prevention of infectious diseases, cancer or allergic diseases.

Methods and compositions for altering the microenvironment of a tumor are provided. The methods comprise reducing the population of tumor-residing immune suppressive regulatory T-cells, increasing the population of tumor lysing T-cells (such as CD8+ T-cells) and improving the efficacy of cancer immunotherapy. The compositions comprise the use of cationic lipids optionally combined with autologous antigens, non-autologous antigens, or tumor-associated antigens.

The disclosure relates to HCMV ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

Provided herein are compositions comprising a liposome comprising ribonucleic acid (RNA) molecules and a cationic lipid, wherein the RNA molecules bind to or encode an epitope of a nucleic acid encoding a fusion protein expressed by a tumor. The disclosure also provides a nanoparticle comprising a positively-charged surface and an interior comprising (i) a core and (ii) at least two nucleic acid layers, wherein each nucleic acid layer is positioned between a cationic lipid bilayer, and nucleic acid molecules in the nucleic acid layers comprise a sequence of a nucleic acid molecule expressed by slow-cycling cells (SCCs). Also provided herein re methods of making a nanoparticle and methods of increasing an immune response against a tumor in a subject. Methods of treating a subject with a disease are provided herein.

This disclosure provides cancer cell lysing agent, formulations comprising cancer cell lysing agent, and methods of using the same for treating cancer.

Compositions and methods for the prevention and/or treatment of a viral infection, in particular of the Coronaviridae family.

The present invention relates to methods and compositions for stimulating an immune response. In particular, the present invention relates to immunostimulatory RNA molecules comprising sequences derived from an Influenza A virus nucleoprotein-encoding RNA molecule that act as adjuvants and/or immunostimulatory agents to enhance host immune responses.
