MYD88 and neoplasm: Thus, the cGAS-STING-TBK1-IRF7 pathway in pDC might also be responsible for IFN-I expression in the cisplatin-treated and irradiated tumor-containing lungs of Oasl1−/− mice, although we cannot rule out the possibility of the contribution of the TLR9-Myd88-IRF7 pathway, which can detect extracellular DNA in pDC [43, 44].
