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 invention relates to a cell membrane penetrating peptide and an intracellular delivery carrier including the same. The intracellular delivery carrier of the present invention has an advantage of efficiently transferring substances into cells even at a low concentration thereof compared with the existing cell membrane penetrating peptide derived from the virus.

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.

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 invention provides an expression vector for preventing or inhibiting HIV entry, fusion or replication in mammalian cells. In particular, the invention provides a recombinant retroviral vector that encodes an inhibitor of a HIV co-receptor, such as CCR5 or CXCR4, and a protein that inhibits HIV fusion to target cells and/or HIV replication. Pharmaceutical compositions comprising such constructs and methods of use thereof to prevent or treat HIV infection in a patient are also disclosed.

The present invention is directed to gene therapy constructs and pharmaceutical compositions for the expression of Kir7.1. The gene therapy constructs include a vector comprising a promoter operably connected to a polynucleotide encoding a Kir7.1 polypeptide. Methods of treating a subject having a condition associated with insufficient expression or function of a Kir7.1 polypeptide are also provided.

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.

Described herein are compositions and methods for treating a subject having or at risk of developing hereditary angioedema. Using the compositions and methods of the disclosure a patient may be provided one or more agents that elevate the expression and/or activity levels of C1-esterase inhibitor (C1-INH). Exemplary agents that may be used in conjunction with the compositions and methods of the disclosure for this purpose include cells, such as pluripotent cells, that express C1-INH.

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.
