Some research has indicated that upregulated expression of GLUT1 in fibroblasts and macrophages can exacerbate pulmonary fibrosis (El-Chemaly et al., 2013; Andrianifahanana et al., 2016), and the pathways in which GLUT1 is involved are mostly focused on inflammation. The gene discussed is SLC2A1; the disease is pulmonary fibrosis.
