CD55 and age-related macular degeneration: We observed a significant decrease in the expression of complement inhibitors, i.e., CFH (Fold change = 0.71, P = 0.02), CD55 (Fold change = 0.50, P = 0.03), CD59 (Fold change = 0.66, P = 0.02), CD46 (Fold change = 0.72, P = 0.04), and CFI (Fold change = 0.55, P = 0.03), in AMD cybrids compared to Older-Normal cybrids (Table 5).
