Oncogenic MAPK signaling in regulating anti-tumor immunity


Mitogen-activated protein kinases (MAPKs) are fundamental enzymes controlling basic cellular functions. While most of the MAPKs are studied in the context of tumorigenesis, the role of MAPK in immune regulation is not well understood. Here, we will investigate the role of both typical and atypical MAPKs in regulating anti-tumor immunity. We will decipher the role of MAPKs in controlling the tumor secretome and further characterize their intrinsic role in controlling DC maturation and activation. These studies will enable us to adroitly administer kinase inhibitors in synergistic therapeutic regimes to augment anti-tumor immunity.
