Crosstalks between tumors and the immune system could be considered a complex and dynamic process that strongly affects the development and progression of cancer. In this regard, epigenetic modifications play a pivotal role in shaping tumor microenvironment, which in turn, modifies anticancer immune responses. Among these mechanisms, DNA methylation, histone modifications, and chromatin remodeling, are particularly involved in a dense and biological network in the modulation of key immune-related pathways (i.e. immune checkpoints, and cytokine signaling), conditions strictly necessary for the evolution of solid cancers.
Significant advances in epigenetic and immunotherapy research have allowed us to open our horizons in the understanding of combination strategies that could contribute to enhance immune recognition and response, such as epigenetic drugs and immune checkpoint inhibitors and/or adoptive cell therapies. However, the main challenge remains to improve patient selection, overcome acquired resistance mechanisms, and reduce toxicities associated with combinatorial strategies in order to reduce tumor burden and activate a durable anti-tumor immune response.
In this Collection, we discuss the intersection of epigenetics and immunotherapy, which extends to intriguing insights regarding immune regulation, biomarkers discovery, and novel therapeutic agents. We welcome submissions of original research articles and reviews.
