Abstract: The present invention provides an engineered T cell for use in a method of treatment of a proliferative disorder, wherein the engineered T cell has modulated expression of one or more genes selected from SIT1, SAMSN1, SIRPG, CD7, CD82, FCRL3, IL1RAP, FURIN, STOM, AXL, E2F1, C5ORF30, CLDND1, COTL1, DUSP4, EPHA1, FABP5, GFI1, ITM2A, PARK7, PECAM1, PHLDA1, RAB27A, RBPJ, RGS1, RGS2, RNASEH2A, SUV39H1, and TNIP3. Further provided are activity modulators of one or more proteins encoded by genes selected from SIT1, SAMSN1, SIRPG, CD7, CD82, FCRL3, IL1RAP, FURIN, STOM, AXL, E2F1, C5ORF30, CLDND1, COTL1, DUSP4, EPHA1, FABP5, GFI1, ITM2A, PARK7, PECAM1, PHLDA1, RAB27A, RBPJ, RGS1, RGS2, RNASEH2A, SUV39H1, and TNIP3 for use in a method of enhancing immunotherapy in a subject having a proliferative disorder. Also provided are related methods of treatment employing the engineered T cell and/or inhibitor.

Abstract: The present invention provides an engineered T cell for use in a method of treatment of a proliferative disorder in a mammalian subject, wherein the T cell has been engineered (i) to overexpress BLIMP1 and/or (ii) to knock-out or decrease expression of BCL6. Further provided is a BCL6 inhibitor for use in a method of enhancing immunotherapy in a subject having a proliferative disorder. Also provided are related methods of treatment employing the engineered T cell and/or BCL6 inhibitor.
