Provided herein are methods of treating brain cancer in a subject, comprising evaluating one or more biological samples from a subject who has brain cancer for the presence of a miRNAs and administering interleukin-12 (IL-12); an immunogenic composition of human telomerase reverse transcriptase (hTERT), Wilms Tumor-1 (WT-1), and prostate specific membrane antigen (PSMA); and an anti-programmed cell death receptor 1 (PD-1) antibody to said subject if the subject has an increased expression level of the mIR-331-3p miRNA or isomiRs thereof and the miR-1537-3p miRNA or isomiRs thereof relative to a control population of subjects. Also provided herein are methods of treating brain cancer in a subject, comprising measuring an expression level of at least one mRNA biomarker selected from SYNGR3, OTX1, GABBR2, LHX1, CADM3, MLLT11, MNX1, GRB14, SLC34A2, PHYHIP, WNT10B, SLC17A6, CRLF1, HOXD13, TGFR3, UBA7, SFRP4, or any combination thereof, in a tumor sample from a subject and administering IL-12; an immunogenic composition hTERT, WT-1, and PSMA; and an anti-PD-1 antibody to said subject if the expression level of SYNGR3, OTX1, GABBR2, LHX1, CADM3, MLLT11, MNX1, GRB14, SLC34A2, PHYHIP, WNT10B, SLC17A6, CRLF1 and HOXD13 is decreased or if the expression level of TGFR3, UBA7, SFRP4 is increased.

Provided herein are systems, compositions, and methods for generating immunogenic peptides or epitopes from tumor associated antigens (e.g., in vivo or ex vivo). Polynucleotides (e.g., genes) encoding the tumor associated antigens may be edited at selected target sites by nucleobase editors comprising a catalytically-inactive Cas9 and a cytosine deaminase, leading to the expression of heteroclitic or cryptic peptides that are more immunogenic than the native peptide derived from the tumor associated antigens. The heteroclitic or cryptic peptide elicit strong tumor-specific immune response (e.g., T-cell response or B-cell response), which inhibits tumor growth and metastasis.

The present invention relates to nanoparticles complexed with biomacromolecule agents configured for treating, preventing or ameliorating various types of disorders, and methods of synthesizing the same. In particular, the present invention is directed to compositions comprising nanoparticles (e.g., synthetic high density lipoprotein (sHDL)) carrying biomacromolecule agents (e.g., nucleic acid, peptides, glycolipids, etc.), methods for synthesizing such nanoparticles, as well as systems and methods utilizing such nanoparticles (e.g., in diagnostic and/or therapeutic settings).

The present disclosure provides an allogeneic whole cell cancer vaccine platform that includes compositions and methods for treating and preventing colorectal cancer. Provided herein are compositions containing a therapeutically effective amount of cells from one or more cancer cell lines, some or all of which are modified to (i) inhibit or reduce expression of one or more immunosuppressive factors by the cells, and/or (ii) express or increase expression of one or more immunostimulatory factors by the cells, and/or (iii) express or increase expression of one or more tumor-associated antigens (TAAs), including TAAs that have been mutated, and which comprise cancer cell lines that natively express a heterogeneity of tumor associated antigens and/or neoantigens, and/or (iv) express one or more tumor fitness advantage mutations, including but not limited to driver mutations. Also provided herein are methods of making and preparing the colorectal cancer vaccine compositions and methods of use thereof.

The invention provides a vaccine comprising a nucleic acid molecule that encodes a dog telomerase reverse transcriptase (dTERT) antigen, as well as methods of using the vaccine to induce an immune response against a TERT and to treat cancer in a mammal.

The present disclosure provides an allogeneic whole cell cancer vaccine platform that includes compositions and methods for treating and preventing breast cancer. Provided herein are compositions containing a therapeutically effective amount of cells from one or more cancer cell lines, some or all of which are modified to (i) inhibit or reduce expression of one or more immunosuppressive factors by the cells, and/or (ii) express or increase expression of one or more immunostimulatory factors by the cells, and/or (iii) express or increase expression of one or more tumor-associated antigens (TAAs), including TAAs that have been mutated, and which comprise cancer cell lines that natively express a heterogeneity of tumor associated antigens and/or neoantigens, and/or (iv) express one or more tumor fitness advantage mutations, including but not limited to driver mutations. Also provided herein are methods of making and preparing the breast cancer vaccine compositions and methods of use thereof.

Also provided herein are methods of treating brain cancer in a subject, comprising measuring an expression level of at least one mRNA biomarker selected from SYNGR3, OTX1, GABBR2, LHX1, CADM3, MLLT11, MNX1, GRB14, SLC34A2, PHYHIP, WNT10B, SLC17A6, CRLF1, HOXD13, TGFR3, UBA7, SFRP4, or any combination thereof, in a tumor sample from a subject and administering IL-12; an immunogenic composition hTERT, WT-1, and PSMA; and an anti-PD-1 antibody to said subject if the expression level of SYNGR3, OTX1, GABBR2, LHX1, CADM3, MLLT11, MNX1, GRB14, SLC34A2, PHYHIP, WNT10B, SLC17A6, CRLF1 and HOXD13 is decreased or if the expression level of TGFR3, UBA7, SFRP4 is increased.

The present invention relates to novel recombinant fusion proteins, such as human antibody-based molecules called Vaccibodies, which are able to trigger both a T cell- and B cell immune response. The present invention also relates to a method of treating a cancer or an infectious disease by means of these specific fusion proteins.

This disclosure provides compositions and methods for stimulating the innate immune response in a subject with agents capable of stimulating an innate immune response in a subject upon administration to the subject (e.g., damage-associated molecular patterns (DAMPs) and pathogen-associated molecular patterns (PAMPs)). In particular, the present invention is directed to compositions of DAMPs/PAMPs and metals ions, as well as systems and methods utilizing such nanoparticles (e.g., in diagnostic and/or therapeutic settings).

A consensus sequence of the antigen telomerase (ConTRt) can be generated and used in preventive and therapeutic vaccination. The consensus sequence of telomerase was generated by the fusion of two sequences, one belonging to human telomerase (hTERT) and the other to dog telomerase (dTERT), with the aim of developing an effective vaccine for the treatment of tumors expressing both human and dog telomerase, hence in both the human and veterinary sectors.
