Disclosed herein are modified NK cells, compositions comprising modified NK cells, and methods for treating a tumor or hyperproliferative disease in a subject. In some embodiments, the modified NK cells include NK cells including a heterologous nucleic acid molecule encoding a CD16 protein comprising a valine at amino acid position 158 (CD16-V158), a heterologous nucleic acid molecule encoding a CCR7 protein, or both. In some embodiments, methods include treating a subject with a tumor by administering a composition comprising an anti-cancer monoclonal antibody and administering a composition comprising the modified NK cells to the subject. Also disclosed are methods of making modified NK cells by obtaining a population of NK cells from a subject and transfecting the population of NK cells with a heterologous nucleic acid molecule encoding CD16-V158, a heterologous nucleic acid molecule encoding a CCR7 protein, or both.

The present invention provides a pluripotent stem cell expressing the following (a) and (b): (a) an exogenous gene encoding CC chemokine receptor 2 type B(CCR2B) (b) an exogenous gene encoding CC chemokine ligand 19 (CCL19), or an NK cell derived from the pluripotent stem cell or a progenitor cell thereof.

This invention is directed to engineered cells and methods for using the same. In embodiments, the engineered cell comprises a nucleic acid encoding a chimeric antigen receptor and a polypeptide, wherein the chimeric antigen receptor is specific for two or more antigens on the surface of a cancer cell, and wherein the polypeptide comprises an antibody or fragment thereof that can be secreted from the engineered cell.

Aspects of the present invention relate to the use of chemokine receptors such as e.g., CCR4 and CCR6, as homing agents. The chemokine receptor(s) is/are expressed by cells containing synthetic chromosomes. The chemokine receptor(s) is/are under controllable expression from a synthetic chromosome and can be used to control an immune response so as to treat or inhibit a disease such as cancer. The control is provided by inducing leukocyte trafficking to sites of disease. If more than one chemokine receptor is expressed, the levels can be individually controlled so that the desired cellular trafficking pattern can be obtained.

This invention is directed to genetically engineered B cells, wherein the B cell expresses and bears on its surface a chimeric B cell receptor, and wherein the genetically engineered B cell further expresses and secretes an antibody or cytokine.

The present application provides identification, in vitro amplification, and application method of memory CD8 T cells specific for an antigen in a solid tumor-draining lymph node.
