PAK4 as a cancer immune-evasion target


Immunotherapy resistance is associated with poor T cell infiltration into tumors. Tumor-cell-intrinsic oncogenic events that contribute to this defect include Wnt–β-catenin activation. PAK4 is now identified as an upstream modulator of this pathway, thus suggesting the potential of enhancing the efficacy of immunotherapy by targeting this druggable kinase.
