Novel therapeutic immunotherapy compositions comprising at least two vectors, each vector encoding a functional CAR, whereby the combination of vectors results in the expression of two or more non-identical binding domains, wherein each vector encoded binding domain(s) are covalently linked to a transmembrane domain and one or more non-identical intracellular signaling motifs are provided herein as well as are methods of use of same in a patient-specific immunotherapy that can be used to treat cancers and other diseases and conditions.

The present disclosure provides compositions and methods for the generation of an antibody or immunogenic composition, such as a vaccine, through epitope focusing by variable effective antigen surface concentration. Generally, the composition and methods of the disclosure comprise three steps: a design process comprising one or more in silico bioinformatics steps to select and generate a library of potential antigens for use in the immunogenic composition; a formulation process, comprising in vitro testing of potential antigens, using various biochemical assays, and further combining two or more antigens to generate one or more immunogenic compositions; and an administering step, whereby the immunogenic composition is administered to a host animal, immune cell, subject or patient. Further steps may also be included, such as the isolation and production of antibodies raised by host immune response to the immunogenic composition.

Disclosed herein are compositions comprising a Human Immunodeficiency Virus (HIV) trans-activator of transcription (Tat) derivative polypeptide with increased immunostimulatory properties relative to the native Tat polypeptide, pharmaceutical compositions comprising the Tat derivative polypeptide, and methods of treating cancer using the Tat derivative polypeptide.

Human immunodeficiency virus (HIV) envelope proteins having specified mutations that stabilize the trimeric form of the envelope protein are provided. The HIV envelope proteins described herein have an improved percentage of trimer formation and/or an improved trimer yield. Also provided are particles displaying the HIV envelope proteins, nucleic acid molecules and vectors encoding the HIV envelope proteins, as well as compositions containing the HIV envelope proteins, particles, nucleic acid, or vectors.

The present specification discloses an immunogenic composition comprising polypeptide, wherein each of the polypeptides has no more than 100 amino acids, which polypeptides comprises one or more sequences having at least 60% homology with any of SEQ ID 1-4, or comprises two or more epitopes having 7 amino acids or more, each epitope having at least 60% homology with a sub-sequence of any of SEQ ID 1-4 that has the same length as the epitope, wherein, the polypeptide is immunogenic in a vertebrate expressing a major histocompatibility complex (MHC) allele, and wherein the polypeptide is not a complete HIV virus protein.

There is disclosed systems and methods for non-invasive delivery of an agent to biological tissues. Delivery of the agent to the tissues can be by one or more modalities. In some embodiments the systems and methods use agent carrier body including a tissue contacting surface for non-invasively engaging tissues under treatment. The tissue contacting surface can be at least partly defined by a plurality of protrusions that are in fluid communication with one or more reservoirs forming part of the agent carrier body. The protrusions may extend outward from an inside of a void and terminate at said tissue contacting surface.

Methods for increasing retinal thickness in a non-diabetic mammal, comprising administering to the mammal one or both of: (i) a composition comprising RBP3 polypeptide, and/or (ii) a composition comprising a nucleic acid encoding an RBP3 polypeptide.

The present invention relates to a retroviral system for the transfer of non-viral RNA into target cells and more particularly a retroviral particle capable of delivering multiple RNAs. More particularly, it relates to retroviral particles comprising a protein derived from the Gag polyprotein an envelope protein, optionally an integrase and at least two encapsidated non-viral RNAs, the encapsidated non-viral RNAs each comprising an RNA sequence of interest linked to an encapsidation sequence, each encapsidation sequence being recognised by a binding domain introduced into the protein derived from the Gag polyprotein and/or into the integrase.

Certain embodiments are directed to recombinant vesiculovirus encoding a heterologous polynucleotide and methods of using the same.
