Provided are a polypeptide and nucleic acid for encoding the polypeptide, a nucleic-acid construct, an expression vector, and a host cell containing the nucleic acid, an antigen-presenting cell presenting the polypeptide on the surface of the cell, and immune effector cell thereof, a pharmaceutical composition containing the polypeptide, a vaccine containing the nucleic acid, the nucleic acid construct, the expression vector, the host cell, the antigen-presenting cell, and the immune effector cell, and an antibody recognizing the polypeptide. Also provided is a therapeutic method using the polypeptide, the nucleic acid, the pharmaceutical composition, the vaccine, and the antibody. Also provided are a diagnosis method and diagnosis apparatus for detecting the described polypeptide. Also provided is an application of the polypeptide in preparing a vaccine, a tumor diagnosis kit, or a pharmaceutical composition, and an application of the polypeptide or the nucleic acid as a test target in tumor diagnosis.

Provided here are compositions comprising engineered lymphocytes that secrete bispecific engager molecules, thereby activating T cells in the local environment to kill target cells. In particular embodiments, engineered lymphocytes selectively target CLL-1 positive leukemic cells, both directly and through activation of a subject's own T cells, while sparing CLL-1 negative cells, such as myeloid progenitor cells. In particular embodiments, engineered lymphocytes selectively target CD123 and CLL-1 positive leukemic cells, both directly and through activation of native T cells.

Improved cancer therapies are provided and include methods for inhibiting growth of tumor cells in an individual by administering to the individual a polynucleotide encoding a protein that contains an immunoglobulin Fc and an antagonist peptide of a receptor expressed by tumor cells, and administering a chemotherapeutic agent to the individual, such that the growth of the tumor cells and/or metastasis of cancer cells is synergistically inhibited. Approaches are also provided for improving cancer therapies that include adoptive immunotherapies by using the polynucleotides to enhance tumor infiltration by immune cells.

A cancer killer cell in which a therapeutic recombinant protein or recombinant protein which improves cytotoxic activity of the cancer killer cell is loaded. In addition, a pharmaceutical composition including the recombinant protein or a recombinant protein-loaded cancer killer cell is disclosed. Further, disclosed is a method for preparing a recombinant protein-loaded cancer killer cell.

Methods and compositions are provided for combined transplantation of a solid organ and hematopoietic cells to a recipient, where tolerance to the graft is established through development of a persistent mixed chimerism. An individual with persistent mixed chimerism, usually for a period of at least six months, is able to withdraw from the use of immunosuppressive drugs after a period of time sufficient to establish tolerance.

The present invention relates to a method for obtaining stable pseudotyped lentiviral particles including a heterologous gene of interest, comprising the following steps: a) transfecting at least one plasmid in appropriate cell lines, wherein said at least one plasmid comprises the gene of interest, the rev. gag and pol genes, and a sequence coding for an ERV syncytin, wherein the rev, gag and pol genes are retroviral genes; b) incubating the transfected cells obtained in a), so that they produce the stable pseudotyped lentiviral particles in the supernatant; and c) harvesting and concentrating the stable lentiviral particles obtained in b). The present invention also relates to a method to transduce immune cells using lentiviral vectors pseudotyped with an ERV syncytin glycoprotein. The method can be performed on non-stimulated blood cells or on cells stimulated briefly with IL7, and the cells can be expanded. The stable pseudotyped lentiviral particles obtained are particularly useful in gene therapy.

Provided herein are methods, compositions and uses involving immunotherapies, such as adoptive cell therapy, e.g., T cell therapy, and inhibitors of a TEK family kinase, such as BTK or ITK. The provided methods, compositions and uses include those for combination therapies involving the administration or use of one or more such inhibitor in conjunction with another agent, such as an immunotherapeutic agent targeting T cells, such as a therapeutic antibody, e.g., a multispecific (e.g., T cell engaging) antibody, and/or genetically engineered T cells, such as chimeric antigen receptor (CAR)-expressing T cells. Also provided are methods of manufacturing engineered T cells, compositions, methods of administration to subjects, nucleic acids, articles of manufacture and kits for use in the methods. In some aspects, features of the methods and cells provide for increased or improved activity, efficacy, persistence, expansion and/or proliferation of T cells for adoptive cell therapy or endogenous T cells recruited by immunotherapeutic agents.

The present invention relates to compositions and transpapillary methods of adoptive cell therapy for the treatment of subjects having or at risk of having breast disorders.

Provided herein are populations of modified NK-92 cells, compositions and kits comprising the cells, and methods of making and using the populations of cells.

The present disclosure provides distinct therapeutic populations of cells that form a pharmaceutical composition useful in hematopoietic stem/progenitor cell transplant. For example, the present disclosure provides a therapeutic population of cells, comprising an enriched population of hematopoietic stem/progenitor cells, memory T cells, regulatory T cells, and wherein the population of cells is depleted of na?ve conventional ??-T cells. The present disclosure further provides methods of treatment using the therapeutic population of cells. In other embodiments, the present disclosure provides methods of producing a therapeutic population of cells.
