CXCR3 and colorectal cancer: Genetic deletion of Spata2 and CYLD enhances infiltration of anti-tumoral CXCR3 T/NK cells and anti-PD-1-mediated tumor regression in vivo. Our results raise the intriguing possibility of therapeutically targeting the SPATA2-CYLD axis to improve responses of colorectal cancer to PD-(L)1 blockade and other immunotherapies.
