Specifically, carbohydrate‐related metabolic pathways in the CD8‐FGFBP2, CD8‐ZNF683, and CD8‐IFNG subgroups were more active in IPF patients, whereas lipid‐related metabolic pathways were more active in the CD8‐ZNF683 subgroup. This evidence concerns the gene IFNG and idiopathic pulmonary fibrosis.
