The paper concluded that the ability of systemic chemokine modulation to eliminate the PD-1-resistance of cold tumors indicates that intratumoral cytotoxic t-lymphocyte accumulation, rather than tumor immunogenicity, is the key factor limiting the therapeutic effectiveness of immune checkpoint inhibitors. These data suggest a broad therapeutic potential of tumor microenvironment reprogramming strategies.

The article, titled "Synergy between TLR3-ligand and IFN-α in the transient sensitization of ‘Cold’ tumors to PD-1 blockade and the induction of systemic immunity," was published in JITC on September 18.
