Provided herein, inter alia, are compositions and methods including recombinant oncolytic viruses expressing CD47 antibody for the treatment of diseases including cancer, immune disorders, and infectious disease.

The present invention is directed to a monoclonal anti-human PD-L1 antibody, or a single-chain variable fragment (scFv), comprising V.sub.H having the amino acid of SEQ ID NO: 3 and V.sub.L having the amino acid of SEQ ID NO: 5. The present invention is also directed to a chimeric antigen receptor fusion protein comprising from N-terminus to C-terminus: (i) a single-chain variable fragment (scFv) of the present invention, (ii) a transmembrane domain, (iii) at least one co-stimulatory domains, and (iv) an activating domain. The inventors have shown that the PD-L1 CAR-T cells of the present invention are more effective than Avelumab PD-L1 CAR-T cells in killing several cancer cell lines. PD-L1 CAR-T can be used alone or in combination with other agent in an immunotherapy.

The present invention relates to a chimeric molecule useful in adoptive cell therapy (ACT), and cells comprising the same. The chimeric molecule can act as a modulator of cellular activity enhancing responses when an endogenous T-cell receptor (TCR) is engaged with its cognate antigen. The present invention also provides proteins, nucleic acids encoding the chimeric molecule and therapeutic uses thereof.

The present disclosure relates to a novel pharmaceutical combination and a use thereof. The pharmaceutical combination can be used to treat cancer, such as colon cancer.

The present disclosure provides methods for inducing neoepitope-specific CD8+ T cells in an individual or for inducing trafficking of neoepitope-specific CD8+ T cells to a tumor in an individual using an RNA vaccine or using an RNA vaccine in combination with a PD-1 axis binding antagonist. Also provided herein are PD-1 axis binding antagonists and RNA vaccines that include one or more polynucleotides encoding one or more neoepitopes resulting from cancer-specific somatic mutations present in a tumor specimen obtained from the individual for use in methods of inducing neoepitope-specific CD8+ T cells in an individual or for inducing trafficking of neoepitope-specific CD8+ T cells to a tumor in an individual.

The present disclosure relates to anti-TRBCl antigen binding domains characterized by the sequences of the variable chains. The CDRs sequences of the variable chains are: (VH CDR1) GYTFT, (VH CDR2) NPYNDDIQS, (VH CDR3) GAGY-NFDGAYRFFDF; and (VL CDR1) RSSQRLVHSNGNTYL, (VL CDR2) RVSNRFP, (VL CDR3) SQSTHVPYT. The claimed humanized antibodies derive from the murine JOVI antibody. Uses in cancer therapy.

The present invention relates to a chimeric molecule useful in adoptive cell therapy (ACT), and cells comprising the same. The chimeric molecule can act as a modulator of cellular activity enhancing responses when an endogenous T-cell receptor (TCR) is engaged with its cognate antigen. The present invention also provides proteins, nucleic acids encoding the chimeric molecule and therapeutic uses thereof.

The use of an HLA-G molecule and its antigenic fragments prepared a broad spectrum vaccine which could be used to prevent the invasion of various tumors and various viruses or unknown virus on human and animal body.

Methods and compositions are disclosed for inducing immune responses against one or more antigens in a mammal.

The present invention relates to: an activity modulator which is a means for modulating the activity of CD300b-dependent phagocytosis; and medicine for the treatment or prevention of a disease or condition in which the activity is involved. The activity modulator comprises a CD300a-binding substance and modulates CD300b-dependent phagocytosis signals in a macrophage.
