Higher plasma levels of CXCL7 have also been found in other autoimmune diseases, such as Sjogren syndrome, Vogt-Koyanagi-Harada syndrome (VKH), and vitiligo (Egerer et al., 2006; Liang et al., 2019; Egbeto et al., 2020), further indicating that CXCL7 could play an important role in the pathogenesis of autoimmune diseases that should be further studied in more detail. This evidence concerns the gene PPBP and Vogt-Koyanagi-Harada disease.
