Prostate cancer cells enhance interleukin-15-mediated expansion of NK cells
ObjectivesTo identify cytokines that can activate and expand NK cells in the presence of prostate cancer cells in order to determine whether these agents may be useful in future intra‐tumoural administration in pre‐clinical and clinical prostate cancer trials.Materials and MethodsLymphocytes isolated from normal donor blood were set up in co‐cultures with either cancer or non‐cancerous prostate ce
