The present invention discloses selective surfaces, wherein said selective surfaces comprise a biocompatible polymer comprising maleic anhydride molecules and an apoptosis inducing ligand bound to the maleic anhydride molecules. The invention also encompasses devices and kits comprising the selective surface and methods for its production. The selective surfaces may be used for functional selection of cell populations suitable for transplantation into human subjects.

Provided is a method for preparing natural killer cell with high efficiency using irradiated peripheral blood mononuclear cells, more particularly to a method for proliferating highly activated NK cells using a combination of irradiated peripheral blood mononuclear cells (PBMCs) and a CD16 antibody and an anti-cancer cell therapeutic composition containing the natural killer cells (NK cells) prepared thereby. Further provided is a method for large-scale proliferation of activated NK cells with high efficiency using a combination of irradiated peripheral blood mononuclear cells (PBMCs) and a CD16 antibody without the use of cancer cells or genetically modified feeder cells having safety issues as feeder cells. The highly purified and highly cytotoxic NK cells proliferated in large quantities can be used as an active ingredient of a cancer immunotherapeutic composition.

Immunogenic peptides from tumor associated stromal cell antigens, including combinations of such peptides, are disclosed herein. In some examples the peptides are useful for methods of eliciting an immune response. In additional examples the peptides are useful for methods of treating cancer. Methods for decreasing vascularization of a tumor using a Protein Delta Homolog 1 (DLK1) protein or a nucleic acid encoding the protein are also disclosed.

The present disclosure provides methods and compositions related to the modification of immune effector cells to increase therapeutic efficacy. In some embodiments, immune effector cells modified to reduce expression of one or more endogenous target genes, or to reduce one or more functions of an endogenous protein to enhance effector functions of the immune cells are provided. In some embodiments, immune effector cells further modified by introduction of transgenes conferring antigen specificity, such as exogenous T cell receptors (TCRs) or chimeric antigen receptors (CARs) are provided. Methods of treating a cell proliferative disorder, such as a cancer, using the modified immune effector cells described herein are also provided.

A method of treating a cancer, the method comprising: providing a modified macrophage or monocyte that contains an exogenous nucleic acid sequence encoding a Hom-1 polypeptide or a fragment thereof that contains the Hom-1 homeobox domain, wherein the modified macrophage or monocyte expresses the Hom-1 polypeptide or the fragment thereof; and administering the modified macrophage or monocyte to a subject with a cancer.

The present disclosure relates to chimeric engulfment receptor molecules, host cells modified to include the phagocytic engulfment molecules, and methods of making and using such receptor molecules and modified cells.

Provided herein are, among other things, methods for treating a patient suffering from an EGFR+ cancer.

The technology relates in part to methods for inducing partial apoptosis of cells that express an inducible caspase polypeptide. The technology further relates in part to methods for inducing partial apoptosis of cells that express an inducible modified caspase polypeptide, having a modified dose response curve to the multimeric ligand inducer. The technology also relates in part to methods for cell therapy using cells that express the inducible caspase polypeptide or the inducible modified caspase polypeptide, where the proportion of caspase polypeptide-expressing cells eliminated by apoptosis is related to the administered amount of the multimeric ligand inducer.

A fusion protein comprising: a first component comprising an antibody, or a fragment or variant thereof; and a second component comprising a cytokine trap or an adenosine deaminase or a fragment or variant thereof. In certain embodiments, the antibody is an anti-PD-1 antibody. In certain embodiments, the antibody binds to a tumor antigen, for example a MUC16 or MUC1 antigen. In certain embodiments, the cytokine trap is a TGF- trap. A polynucleotide encoding such a fusion protein and a vector comprising such a polynucleotide. A composition comprising the fusion protein. A method of using the composition, including in the treatment of cancer.

The present disclosure relates to IL2 agonists with improved therapeutic profiles.
