Figure 3. The expression of selected alternative pathway-related complement genes. The expression of CFI, CFH, CFB, and CFHR1 in retina and retinal pigment epithelium (RPE)/choroid (A) and primary cultured RPE cells, B6-RPE07 cell line, primary cultured retinal microglia (Ret_microglia), brain microglia (Bri_microglia), and BV-2 cells (B) were analyzed by reverse transcriptase-PCR. Total RNA from mouse liver tissue was used as a positive control. CFH, complement factor H; CFB, complement factor B; CFI, complement factor I CFHR1, complement factor H-related protein 1.
