Compositions and methods are disclosed herein for producing one or more immunoglobulins in an isolated cytotoxic B lymphocyte cell line. An isolated cell line includes an isolated B lymphocyte cell line capable of expressing at least one exogenously incorporated membrane immunoglobulin capable of binding to a first antigen and at least one endogenous secreted immunoglobulin capable of binding to a second antigen, and further capable of expressing at least one exogenously incorporated recombinant B cell receptor that signals for expression of cytotoxic effector molecules.

Provided herein are methods, compositions and uses involving T cell therapies, such as adoptive T cell therapy, and an inhibitor of a Diacylglycerol kinase (DGK). The provided methods, compositions and uses include those involving the administration or use of one or more DGK inhibitors (DGKi) in a combination therapy with a T cell therapy, such as a genetically engineered T cell therapy involving cells engineered with a recombinant receptor, such as chimeric antigen receptor (CAR) or T cell receptor (TCR).

The present invention relates to a pharmaceutical preparation for treating an inflammatory condition, preferably a condition associated with ischemia comprising: a) a physiological solution comprising peripheral blood mononuclear cells (PBM-Cs) or a subset thereof, or b) a supernatant of the solution a), wherein the solution a) is obtainable by cultivating PBMCs or a subset thereof in a physiological solution free of PBMC-proliferating and PBMC-activating substances for at least 1 h.

The present invention provides methods for inducing and expanding anti-tumor immunity leading to enhanced clinical and immunotherapeutic responses. The invention also provides novel compositions and methods for the treatment of cancer.

An object of the present invention is to provide a therapeutic strategy in the solid tumor area and a means useful therefor to further advance the clinical application of CAR therapy. There is prepared a gene-modified lymphocyte which expresses a chimeric antigen receptor having an EphrinB2 extracellular domain at the antigen recognition site.

The present invention provides methods and compositions related to multivalent carbohydrate antigen structures comprising cancer or infection associated ganglioside carbohydrate antigens. Said carbohydrate structures may be used to induce immunity against said carbohydrate antigens. In some embodiments, carbohydrate structures may be administered to a subject thereby inducing immunity in the subject, for example, the administration of a vaccine comprising said carbohydrate structure. Also provided are methods to induce an immune response in a subject in need thereof by administering said carbohydrate structure. Further provided are methods of producing an antibody or TCR that bind said carbohydrate antigens.

Disclosed herein are methods for treating cancer comprising administering CAR-modified immune cells and at least one Retinoic Acid Receptor agonist.

A method for producing natural killer cells is disclosed. The method comprises isolating peripheral blood mononuclear cells (PBMCs) from a blood sample; isolating at least one of CD56+ cells and/or CD3/CD56+ cells from the PBMCs; and co-culturing the at least one of CD56+ cells and/or CD3/CD56+ cells with a combination of feeder cells in the presence of a cytokine. A composition for treating cancer is also disclosed. The composition comprises the CD56+ natural killer cells produced by the disclosed method and a cytokine.

Disclosed herein are methods for treating cancer comprising administering CAR-modified immune cells and at least one Retinoic Acid Receptor and/or Retinoid X Receptor active agent.

The present invention relates to chimeric immune receptor molecules for reducing or eliminating tumors. The chimeric receptors are composed a C-type lectin-like natural killer cell receptor, or a protein associated therewith, fused to an immune signaling receptor containing an immunoreceptor tyrosine-based activation motif. Methods for using the chimeric receptors are further provided.
