Compositions that include anti-cancer, anti-tumor, and anti-microbial infection peptides are provided. In some embodiments, the compositions include 1-10 or more synthetic peptides that are between 8 and 50 amino acids long and include an amino acid sequence as disclosed herein. Also provided are in vitro populations of dendritic cells that include the compositions, in vitro populations of T cells capable of being activated uponbeing brought into contact with the populations of dendritic cells, antibodies and antibody-like molecules that specifically bind to complexes of an MHC class I molecule and the peptides, methods for using the disclosed compositions for treating and/or preventing cancer and/or microbial infections, methods for making cancer vaccines and anti-microbial vaccine, methods for screening peptides for inclusion in immunotherapy compositions, methods for determining a prognosis of a patient with a cancer and/or a microbial infection, kits that include the disclosed peptides, and methods for treating and/or preventing diseases, disorders, and/or conditions associated with hyperphosphorylation of MHC I peptides and/or MHC II peptides, inadequate PP2A activity, and/or undesirable CIP2A activity.

Provided are peptide-MHC class I and class II molecules having improved stability and high potency, and that can be produced in high yield. Also provided are receptor-signaling nanoparticles comprising the improved peptide-MHC molecules.

This invention provides WT1 peptides and methods of treating, reducing the incidence of, and inducing immune responses against a WT1-expressing cancer, comprising same.

The invention relates to improved strategies, compositions, and methods for producing neoplasia vaccines and for their use in methods of treating cancer in a patient. In aspects, a method of treating cancer comprises: (a) administering an effective amount of one or more of the instantly-disclosed peptides or polypeptides comprising one or more identified shared neo-epitopes (including peptides or polypeptide comprising one or more peptides or polypeptides from Table A, B, and/or C and/or fragments and variants thereof); and subsequently (b) administering an effective amount of one or more of the instantly-disclosed subject-specific peptides or polypeptides comprising one or more identified subject-specific neo-epitopes. The peptides or polypeptides administered in step (a) and in step (b) are designed to exclude neo-epitopes that are known or determined (e.g. predicted) to engage regulatory T cells and/or other detrimental T cells (including T cells with potential host cross-reactivity and/or anergic T cells).

The invention relates to a CD84 inhibitor for use in treating or preventing of an ischemic disease and/or ischemic tissue damage, the use of a CD84 inhibitor for inhibiting CD84 mediated T cell migration in vitro and a method for screening for a CD84 inhibitor.

Disclosed are compositions comprising an expressible nucleic acid sequence comprising a first nucleic acid sequence comprising a leader sequence or a pharmaceutically acceptable salt thereof; and a second nucleic acid sequence comprising a sequence that encodes a trimer of a retroviral envelope or a pharmaceutically acceptable salt thereof. In some embodiments, the expressible nucleic acid sequence further comprises a nucleic acid sequence encoding at least one viral antigen or a pharmaceutically acceptable salt thereof. In some embodiments, the expressible nucleic acid sequence further comprises at least one nucleic acid sequence encoding a linker. Also disclosed are pharmaceutical compositions comprising these compositions and methods of using the disclosed compositions.

A pDNA-based vaccine against SARS-CoV-2 and methods for preventing or treating COVID-19 using it.

Toll-like receptor (TLR) ligands having an allose-based core are stable in aqueous formulation and are useful in treating, preventing, or reducing susceptibility to diseases or conditions mediated by TLRs, such as cancer, infectious disease, allergy, autoimmune disease, sepsis, and ischemia reperfusion.

Provided herein are antibodies to DC-SIGN, conjugates of DC-SiGN antibodies, and DC-SiGN antibody fusion proteins and the use of such antibodies, conjugates, and fusion proteins for the treatment of diseases such as cancer.

The present disclosure provides a method of treating a solid tumor cancer. The method includes administering a combination to a subject in need thereof. The combination includes at least two chemotherapy agents and a dose of a composition consisting essentially of attenuated Salmonella typhimurium. The present disclosure also provides an anti-tumor agent for use in a method of treating cancer. In such instances, the anti-tumor agent may include the combination.
