Warming up the tumor microenvironment in order to enhance immunogenicity

Abstract

We have recently demonstrated that intratumoral CpG-B vaccination enhances anti-tumor immunity and tumor regression in mice. We further show that the local delivery of TLR9 agonists converts the tolerogenic tumor microenvironment into an immunopermissive one, which may benefit current immunotherapeutic anticancer strategies by enhancing innate and adaptive tumor-associated immune cell responses.
