CD47 and Schnyder corneal dystrophy: RBCs from individuals with SCD express P-selectin, basal cell adhesion molecule-1/lutheran protein [53], integrin-associated protein (IAP) [54], and vascular cell adhesion molecule (VCAM), which cause RBCs to bind to one another, inflammatory cells such as monocytes and neutrophils, and vascular endothelial layers [55,56,57].
