STING facilitates the development of radiation-induced lung injury via regulating the PERK/eIF2α pathway

Radiation-induced lung injury (RILI) is one of the serious adverse reactions of thoracic radiotherapy, which largely limits the dose and therapeutic effect of radiotherapy. The underlying mechanism has not been elucidated. RILI is characterized by an acute inflammatory response, and stimulator of interferon genes (STING) has been reported to play an important role in regulating inflammation and innate immune activation. However, its role in RLLI, remains unclear. Here, we reported the potential therapeutic effect of STING inhibitor H-151 on RILI.
