VEGFA and infection: Other studies have indicated that epidermal growth factor (EGF), macrophage inflammatory protein (MIP)-1β, IL-1α, transforming growth factor (TGF)-α, soluble CD40 ligand (sCD40L), vascular endothelial growth factor (VEGF), IP-10, TNF-α, IL-12(p40), might discriminate between active TB and infection [16], [19], [20], [28].
