Chimeric transmembrane immunoreceptors (CAR) targeted to PSCA are described.

The present invention relates to compositions and methods for generating a modified T cell with a nucleic acid capable of downregulating endogenous gene expression selected from the group consisting of TCR chain, TCR chain, beta-2 microglobulin, a HLA molecule, CTLA-4, PD1, and FAS and further comprising a nucleic acid encoding a modified T cell receptor (TCR) comprising affinity for a surface antigen on a target cell or an electroporated nucleic acid encoding a chimeric antigen receptor (CAR). Also included are methods and pharmaceutical compositions comprising the modified T cell for adoptive therapy and treating a condition, such as an autoimmune disease.
