The present invention provides an anti-human MSLN-specific antibody and an MSLN-targeting immune effector cell. Also provided is an MSLN-targeting chimeric antigen receptor modified T-cell prepared using the antibody and a use thereof.

The present invention provides humanized monoclonal antibodies, bi-specific antibodies, antibody conjugates, and fusion proteins that bind to the chemokine receptor CCR4. This antibody is derived from CCR4-IgG1 and recognizes the same epitope. This antibody contains either an IgG4 or a stabilized IgG4 in order to improve binding efficiency and reduce in vivo Fab arm exchange. Binding of the antibodies disclosed herein to CCR4 inhibits ligand-mediated activities and is used to treat symptoms of cancer.

The instant disclosure is directed to methods for generating stem cell-derived immune cells with enhanced function. Disclosed herein are methods for modifying a stem or progenitor cell capable of differentiating into an immune cell to inhibit the function of at least one gene selected from DGK? and DGK?, and directing differentiation of that stem or progenitor cells towards enhanced immune cells. Also disclosed herein are immune cells or stem cells made by the present methods, as well as the use of immune cells in therapeutic treatment.

This disclosure describes, generally, a modified form of CD 16, genetically-modified cells that express the modified CD 16, and methods that involve the genetically-modified cells. The modified form of CD 16 can exhibit increased anti-tumor and/or anti- viral activity due, at least in part, to reduced susceptibility to ADAM17-mediated shedding upon NK cell stimulation.

The invention provides HPV agonist epitopes, which can be used as a peptide, polypeptide (protein), and/or in a vaccine or other composition for the prevention or therapy of HPV infection and/or cancer. The invention further provides a nucleic acid encoding the peptide or polypeptide (protein), a vector comprising the nucleic acid, a cell comprising the peptide, polypeptide (protein), nucleic acid, or vector, and compositions thereof.

Disclosed are compositions and methods relating to the treatment of a cancer via the induction of PDL1 and use of anti-PDL1 antibodies.

Compositions of multipeptide vaccines comprising at least seven tumor associated antigens, compositions of antigen presenting cell (e.g., dendritic cell) based vaccines presenting epitopes from at least seven tumor associated antigens, and methods of making same, are provided herein. Also, disclosed are methods for treating gynecological and peritoneal cancers using such vaccines.

Provided herein is a composition comprising, a cell, comprising nucleic acids encoding a chimeric antigen receptor (CAR) and one or more of signaling proteins selected from K13-vFLIP, MC159-vFLIP, cFLIP-L, cFLIP-p22, HTLV1-Tax and HTLV2-Tax, wherein the CAR comprises an a) extracellular antigen specific domain, b)a transmembrane domain and c) an intracellular signaling domain comprising an immunoreceptor tyrosine-based activation motif (ITAM); wherein c) is located at the C-terminus of the chimeric receptor. In some embodiments, the CAR further comprises one or more co-stimulatory domains. Also provided herein are methods for treating diseases using the compositions described herein.

Embodiments of the disclosure concern methods and compositions related to preparation and use of combinatorial immunotherapies. In specific embodiments, compositions comprising NK cells prepared in a particular manner also include certain antibodies. These compositions are utilized for treatment, such as for cancer treatment. In particular embodiments, the compositions include complexes of the NK cells and the antibodies in which the antibody is bound to the NK cells and may also bind to another antigen, such as on a cancer cell.

The present invention provides novel fusion proteins comprising two cytokines: interleukin-6 (IL-6) and interleukin-1 beta (IL-1?). Methods of using the fusion proteins to activate target cells or treat a disease are also provided.
