Moreover, chronic conjunctival inflammation in VKC is associated with increased expression of α3 and α6 integrin subunits' receptors, epidermal growth factor receptor (EGFR), VEGF, transforming growth factor-b (TGF-b), basic fibroblast growth factor (bFGF), and platelet-derived growth factor (PDGF), thus suggesting a possible contribution of integrins, EGFR, and growth factors in VKC conjunctival remodeling and also a role of growth factors in the expression and function of integrins [8]. This evidence concerns the gene VEGFA and inflammation.
