Mechanism of RT and YM101 combined therapy. Upper panels illustrate that schematic representation of the tumor microenvironment (TME) before and after treatment with RT and YM101. Combined RT and YM101 treatment induce multiple effects, including immune activation (increased DC maturation and pro-inflammatory cytokine/chemokine production), reduced T cell exhaustion, and enhanced T cell infiltration. Lower panels illustrate the impact of YM101 on radiation-induced pulmonary fibrosis (RIPF), demonstrating attenuated ECM deposition and fibrosis. The ability to attenuate RIPF while enhancing antitumor efficacy potentially broaden the therapeutic window for RT in the cancer treatment
