The same research group reported similar results in the model of experimental allergic esophagitis, with disease amelioration in TRAIL −/− mice (Collison et al., 2015) and proposed a disease-promoting role of Mid-1 downstream of TRAIL in the pathogenesis of pulmonary fibrosis (Collison et al., 2019). The gene discussed is TNFSF10; the disease is pulmonary fibrosis.
