Described herein are implantable devices comprising cells engineered to express and secrete antigens of infectious agents. The devices are useful for inducing protective immune responses against infectious agents.

The present disclosure provides a dendric cell tumor vaccine comprising a chimeric antigen receptor for activating the dendritic cell and a tumor antigen. The present disclosure also provides compositions and methods of making the dendritic cell tumor vaccine, and the methods of using the dendritic cell tumor vaccine to treat cancer.

Synthetic bacterial messenger RNA can be used to prepare autologous, allogenic or direct nucleic acid cancer vaccines. Cancer cells are transfected either in vitro or in vivo with mRNA obtained from DNA that encodes an immunogenic bacterial protein. An immune response to the cancer is generated from direct administration of the mRNA in vivo or administration of vaccines prepared from cancer cells in vitro. Codon modification of the mRNA can optimize expression of an immunogenic polypeptide in cancer cells.

The present invention relates to a method for inducing an immune response in a human or animal subject, as well as to a pharmaceutical composition for inducing an immune response, furthermore to a method for producing the pharmaceutical composition in vitro and the use of cytotoxic CD8+ T-lymphocytes activated to recognize an antigenic peptide in a pharmaceutical composition or in a method for inducing an immune response.

The present application relates to an attenuated oncolytic virus strain, an oncolytic virus vaccine and a drug for treating tumors by combining the oncolytic virus vaccine with immune cells. The present application provides a new attenuated oncolytic virus strain by a site-directed mutation of a matrix protein M of a VSV wild-type virus. On the basis of the attenuated oncolytic virus strain, the present application further provides a vaccine that can be used in tumor treatment. On the basis of the vaccine, the present application further provide a drug that can effectively treat multiple kinds of tumors by combining the vaccine with immune cells.

The present disclosure comprises a cancer peptide vaccine comprising a peptide of Asn-Val-Leu-His-Phe-Phe-Asn-Ala-Pro-Leu (SEQ ID NO: 1), a peptide of Ala-Ser-Leu-Asp-Ser-Asp-Pro-Trp-Val (SEQ ID NO: 2), a peptide of Lys-Leu-Lys-His-Tyr-Gly-Pro-Gly-Trp-Val (SEQ ID NO: 3), and a peptide of Leu-Leu-Gln-Ala-Glu-Ala-Pro-Arg-Leu (SEQ ID NO: 4), and a method of preparing the same.

The present invention inter alia relates to a method of selecting a patient for treatment of a solid tumor, wherein cells of the tumor express the human melanoma associated antigen 1, to a method of predicting whether a patient being diagnosed with a MAGE-1A positive solid tumor will be responsive to treatment of this tumor as well as to methods of treating a patient being diagnosed with a MAGE-1A solid tumor. The invention also relates to a pharmaceutical composition comprising T cells expressing a T cell receptor that specifically binds MAGE-1A and to a diagnostic immunostaining kit for selecting a patient for treatment of a solid tumor.

The present disclosure provides, inter alia, compositions, cell populations and pharmaceutical compositions and methods useful for the treatment of inflammatory diseases or disorders. In some embodiments, the compositions, cell populations and pharmaceutical compositions and methods comprise a population of CD44.sup.+ cells modified ex vivo via treatment with a CD44 ligand for a period of time sufficient to prime the cells to produce elevated levels of one or more anti-inflammatory or immunomodulatory molecules relative to a native populations of CD44.sup.+ cells. In some embodiments, the compositions, cell populations and pharmaceutical compositions and methods comprise a population of CD44.sup.+ cells modified ex vivo via a treatment that is effective to target cells to sites of inflammation.

Described herein are nanoparticle bound self-antigens as an immune and vaccine formulations to elicit self-regulations and reduce atherosclerosis. The use of apolipoprotein B100 (ApoB-100) peptide P210 was investigated in self-assembling peptide amphiphile micelles (P210-PAM) as a vaccine formulation to reduce atherosclerosis in ApoE.sup.−/− mice. Demonstrated herein, P210 provided T cell activation and memory response in peripheral blood mononuclear cells of human subjects with atherosclerotic cardiovascular disease, and dendritic cell uptake of P210-PAM and its co-staining with major histocompatibility complex class I (MHC-I) molecules supported its use as an immunogenic composition. In ApoE.sup.−/− mice, immunization with P210-PAM dampened P210-specific CD4.sup.+ T cell proliferative response and CD8.sup.+ T cell cytolytic response, modulated macrophage phenotype, and significantly reduced aortic atherosclerosis. P210-PAM immunization also reduced atherosclerosis in chimeric mice with human MHC-I allele.

Disclosed herein are methods and compositions comprising placental adherent stromal cells for treating viral infections and sequelae thereof.
