Detection of mRNA expression of costimulatory molecules in ocular PE. mRNA, extracted from cultured IPE, CBPE, and RPE cells with or without 100 U/ml recombinant IFN-γ (samples 1–6), and from freshly obtained mouse iris, ciliary body, and retina (samples 7–9), was reverse transcribed and amplified by PCR using primers for (A) CD80 (B7-1), (B) CD86 (B7-2), (C) PD-L1 (B7-H1), (D) CD40, and (E) GAPDH. PCR products were electrophoresed in 1.5% agarose gel and visualized by staining with ethidium bromide.
