Prostate cancer is largely unresponsive to immunotherapy. A new study finds elevated expression of the chemokine IL-8, or its mouse homolog Cxcl15, in prostate cancer after castration, which leads to the recruitment of immunosuppressive myeloid cells. Blocking tumor infiltration with these cells could improve the response to immune-checkpoint inhibition and androgen-deprivation therapy.
