Disclosed herein are cells that are immune cells or precursor cells thereof, which cells recombinantly express a chimeric antigen receptor (CAR), and a dominant negative form of an inhibitor of a cell-mediated immune response of the immune cell, wherein the CAR binds to a cancer antigen. Also disclosed herein are T cells that recognize and are sensitized to a cancer antigen, which T cells recombinantly express a dominant negative form of an inhibitor of a T cell-mediated immune response. Additionally provided are methods of using such cells to treat cancer in a subject in need thereof.

Disclosed is an SamRNA vaccine, including a recombinant viral vector which includes: i) a viral gene replication complex including nucleotide sequences encoding viral gene replication-related proteins nsP1, nsP2, nsP3, and nsP4; and ii) a nucleotide sequence encoding at least one antigen. According to the SamRNA vaccine of the present invention, in addition to that a promoter of a modified adenoviral vector itself can transcribe an antigen gene to form mRNA, the viral gene replication-related proteins nsP1-4 use RNA as a template to synthesize a large amount of mRNAs, and the immune effect of a target antigen is greatly improved.

The present invention relates to nanoparticles complexed with biomacromolecule agents configured for treating, preventing or ameliorating various types of disorders, and methods of synthesizing the same. In particular, the present invention is directed to compositions comprising nanoparticles (e.g., synthetic high density lipoprotein (sHDL)) carrying biomacromolecule agents (e.g., nucleic acid, peptides, glycolipids, etc.), methods for synthesizing such nanoparticles, as well as systems and methods utilizing such nanoparticles (e.g., in diagnostic and/or therapeutic settings).

The present invention provides immunoresponsive cells, including T cells, cytotoxic T cells, regulatory T cells, and Natural Killer (NK) cells, expressing an antigen recognizing receptor and an inhibitory chimeric antigen receptor (iCAR). Methods of using the immunoresponsive cell include those for the treatment of neoplasia and other pathologies where an increase in an antigen-specific immune response is desired.

The present application relates generally to genetically modified arenaviruses that are suitable vaccines against neoplastic diseases, such as cancer. The arenaviruses described herein may be suitable for vaccines and/or treatment of neoplastic diseases and/or for the use in immunotherapies. In particular, provided herein are methods and compositions for treating a neoplastic disease by administering a genetically modified arenavirus in combination with an immune checkpoint inhibitor, wherein the arenavirus has been engineered to include a nucleotide sequence encoding a tumor antigen, tumor associated antigen or antigenic fragment thereof.

This disclosure provides compositions and methods for stimulating the innate immune response in a subject with agents capable of stimulating an innate immune response in a subject upon administration to the subject (e.g., damage-associated molecular patterns (DAMPs) and pathogen-associated molecular patterns (PAMPs)). In particular, the present invention is directed to compositions of DAMPs/PAMPs and metals ions, as well as systems and methods utilizing such nanoparticles (e.g., in diagnostic and/or therapeutic settings).

Disclosed are means, methods and compositions of matter useful for amplification of adaptive immune responses towards neoplastic tissue. In one embodiment, immunization of a patient is performed by a means comprising of administering either an exogenous vaccine or stimulation of immunogenicity of the tumor so as to cause release of antigens/increased exposure of antigens, thus resulting in an “endogenous” vaccine. Subsequent to vaccination a patient is treated by an immunopheresis procedure, in order to allow for removal of “blocking factors” produced by the tumor or produced by cells programmed by tumors to produce said blocking factors. In one embodiment further immunization is performed subsequent to removal of said blocking factors in order to allow for enhancement of adaptive immune responses

Disclosed are compositions of matters, cells, and treatment protocols useful for induction of anticancer responses in a patient suffering from cancer. In one embodiment the invention provides the use of NR2F6 silencing or gene editing in cord blood cells possessing anti-tumor activity in order to induce potentiated killer cells suitable for therapeutic use. In one embodiment said allogeneic cord blood killer cells are administered to initiate a cascade of antitumor immune responses, with initially responses mediated by allogeneic killer cells, and followed by endogenous immune responses.

Provided herein are immunogenic compositions comprising a recombinant modified vaccinia virus Ankara (MVA) comprising a nucleic acid sequence encoding a CD40 ligand (CD4OL) and a nucleic acid sequence encoding a heterologous disease-associated antigen, wherein the immunogenic composition induces increases T-cell immune responses specific for the heterologous disease-associated antigen when administered to a human host, and related methods and uses.

The invention provides a vaccine comprising a nucleic acid molecule that encodes a dog telomerase reverse transcriptase (dTERT) antigen, as well as methods of using the vaccine to induce an immune response against a TERT and to treat cancer in a mammal.
