This invention provides a system of providing and a process of creating personalized immunotherapeutic compositions for a subject having a disease or condition, including therapeutic vaccine delivery vectors comprising gene expression constructs expressing peptides associated with one or more neo-epitopes or peptides containing mutations that are specific to an subject's cancer or unhealthy tissue. The invention further provides a scalable fully enclosed single use cell growth system, wherein the entire process of manufacturing of personalized immunotherapeutic compositions, up to and including dispensing said composition into containers for patient delivery is carried out within a single enclosed fluid flow path.

Methods and compositions for modifying T-cells in which PD1 and/or CTLA-4 is repressed and/or inactivated using fusion proteins such as artificial transcription factors and nucleases.

The invention provides chimeric antigen receptors (CARs) comprising an antigen binding domain of human antibody 139, an extracellular hinge domain, a transmembrane domain, and an intracellular domain T cell receptor signaling domain. Nucleic acids, recombinant expression vectors, host cells, populations of cells, antibodies, or antigen binding portions thereof, and pharmaceutical compositions relating to the CARs are disclosed. Methods of detecting the presence of cancer in a host and methods of treating or preventing cancer in a host are also disclosed.

This disclosure describes, generally, a modified form of CD 16, genetically-modified cells that express the modified CD 16, and methods that involve the genetically-modified cells. The modified form of CD 16 can exhibit increased anti-tumor and/or anti- viral activity due, at least in part, to reduced susceptibility to ADAM17-mediated shedding upon NK cell stimulation.

Methods and compositions for treating cancers (e.g., neural cancers) by dendritic cell vaccination are provided herein.

The invention relates to the regulated expression of a chimeric antigen receptor (CAR) within a lentiviral vector. The CAR comprises a hook-binding domain that interacts with a hook, preferably encoded by the same lentiviral vector, which prevents proper processing and release of the CAR to the cell membrane. The invention encompasses vectors, methods of making the vectors, and methods of using them, including medicinal uses. The vectors can be used for administration to humans to induce immune responses and to treat cancers and tumors.

The technology relates in part to methods for controlling the activity or elimination of therapeutic cells using molecular switches that employ distinct heterodimerizer ligands, in conjunction with other multimeric ligands. The technology may be used, for example to activate or eliminate cells used to promote engraftment, to treat diseases or condition, or to control or modulate the activity of therapeutic cells that express chimeric antigen receptors or recombinant T cell receptors.

The invention provides compositions and methods for overcoming poor response to antibody therapy, for example, antibody resistance. The invention also relates to at least one immune receptor (IR) specific to the Fc receptor, vectors comprising the same, and recombinant T cells comprising the Fc immune receptor. The invention also includes methods of administering a modified T cell expressing an immune receptor that comprises a Fc binding domain.

The current invention provides monocytic cells transfected with chimeric antigen receptor (CAR) to selectively home to tumors and upon homing differentiate into dendritic cells capable of activating immunity which is inhibitory to said tumor. In one embodiment of the invention, monocytic cells are transfected with a construct encoding an antigen binding domain, a transcellular or structural domain, and an intracellular signaling domain. In one specific aspect of the invention, the antigen binding domain interacts with sufficient affinity to a tumor antigen, capable of triggering said intracellular domain to induce an activation signal to induce monocyte differentiation into DC.

The present disclosure provided compositions and methods for treating solid tumors. In certain aspects, the disclosure provides modified immune cells (i.e. CAR T cells) wherein CD5 has been disrupted or knocked-out.
