Specifically, in the SSc-PF “cytokine-cytokine receptor interaction” pathway under TNF Family (Supplementary Figure 8), TNFSF14-associated perturbation (labeled LIGHT) that leads to upregulation of LTBR, HVEM, and DCR3 was not observed in IPF (Supplementary Figure 10). This evidence concerns the gene LTBR and idiopathic pulmonary fibrosis.
