Additionally, CD147 is strongly expressed on endothelial cells in the brain [73], gastrointestinal tract tissues [74], platelets [75], conjunctival tissues [76], kidney glomerular cells and podocytes [77], and cardiac pericytes [16, 78], where it could serve a more dominant role in SARS-CoV-2 infection and mediate COVID-19-related neurological disturbance, digestive tract vascular damage, increased thrombosis, conjunctivitis, acute kidney injury, and cardiovascular disruption, respectively. Here, BSG is linked to conjunctivitis.
