A non-naturally occurring polynucleotide encoding a miRNA that inhibits the expression of an immune checkpoint protein. The polynucleotide may further encode a chimeric receptor, a cytokine, and/or a cell tag. A vector comprising the aforementioned polynucleotide. A modified immune effector cell comprising the aforementioned polynucleotide. Compositions and kits comprising the aforementioned polynucleotide and/or cell. A method for treating a subject suffering from a disease or disorder, comprising administering the aforementioned cell to a subject in need thereof. The use of the aforementioned cell in the manufacture of a medicament for the treatment of a disease or disorder. A method for the detection of a disease or disorder associated with the overexpression of an antigen in a subject. A method for the treatment of a disease or disorder comprising the serial administration of polynucleotides encoding a chimeric antigen receptor or a cell comprising the same.
