The present invention relates to a pharmaceutical composition comprising a modified mRNA that is stabilised by sequence modifications and optimised for translation. The pharmaceutical composition according to the invention is particularly well suited for use as an inoculating agent, as well as a therapeutic agent for tissue regeneration. In addition, a process is described for determining sequence modifications that promote stabilisation and translational efficiency of modified mRNA of the invention.

A device that includes a scaffold composition and a bioactive composition with the bioactive composition being incorporated into or coated onto the scaffold composition such that the scaffold composition and/or a bioactive composition controls egress of a resident cell or progeny thereof. The devices mediate active recruitment, modification, and release of host cells from the material.

Methods and compositions for constructing and producing recombinant adenovirus-based vector vaccines are provided. In particular aspects, there are be provided compositions and methods involving adenovirus vectors comprising genes for target antigens, such as pro state-specific antigen (PSA), pro state-specific membrane antigen (PSMA), MUC1, CEA, and/or Brachyury, and costimulatory molecules for use in treatment methods that generate highly reactive anti-tumor immune responses and that allows for multiple vaccinations in individuals with preexisting immunity to adenovirus.

The present invention provides an isolated cell composition suitable for adoptive immunotherapy, as well as methods of manufacturing the cell compositions and methods of treatment with the cell compositions. The composition comprises, in a pharmaceutically acceptable carrier, at least about 10.sup.6 CD8+ T cells specific for target peptide antigen(s). In various embodiments, the composition is predominately CD8+ T cells, and at least about 20% of T cells in the composition exhibit a central or effector memory phenotype, providing for a robust and durable adoptive therapy from a natural T cell repertoire that has undergone natural selection.

Double stranded mRNA. e.g., produced in vitro, as well as method of making and using the ds mRNA, are provided.

The present invention concerns methods and compositions for evoking protective immune responses against pathogen infection or cancer. In certain embodiments, the methods and compositions comprise a lymphangiogenesis inducer and an antigen.

The methods and kits disclosed in the present disclosure allow quantified exchange of peptides into MHC proteins. These methods and kits allow MHC proteins with exchanged peptides to be used in further applications such as cell staining. The methods and kits may also be used to quantify peptides present in complex mixtures.

Described herein is a method of preventing or treating a disease in a mammalian subject, comprising administering to the subject who is in need thereof an effective dosage of a pharmaceutical composition comprising a virus like particle (VLP) comprising: an alphavirus replicon comprising a recombinant polynucleotide, wherein the polynucleotide comprises a sequence encoding both subunits of a human class II major histocompatibility antigen, a retroviral gag protein, and a fusogenic envelope protein, wherein the VLP does not contain an alphavirus structural protein gene.

The present invention relates to a pharmaceutical composition comprising a modified mRNA that is stabilized by sequence modifications and optimized for translation. The pharmaceutical composition according to the invention is particularly well suited for use as an inoculating agent, as well as a therapeutic agent for tissue regeneration. In addition, a process is described for determining sequence modifications that promote stabilization and translational efficiency of modified mRNA of the invention.

Provided are compositions that include one or more peptides, wherein each peptide is at least 8 amino acids long and has an amino acid sequence as set forth in any of SEQ ID NOs: 1-45. Also provided are in vitro populations of dendritic cells that include the disclosed compositions, in vitro populations of CD8.sup.+ T cells capable of being activated upon being brought into contact with the disclosed populations of dendritic cells, antibodies or antibody-like molecules that specifically bind to complexes of MHC class I molecules and the disclosed peptides, methods for treating and/or preventing cancer such as leukemia using the disclosed compositions and/or populations, methods for making cancer vaccines using the disclosed compositions, methods for screening target peptides for inclusion in an immunotherapy composition, methods for determining a prognosis of a leukemia patient, and kits that include at least one of the disclosed peptides.
