Ephrin B1 Regulates Inflammatory Pathways in Retinal Müller Cells

The role of inflammation has been accepted as a factor in the complications of diabetic retinopathy. Discovery of the upstream regulation of these inflammatory factors has remained a challenge. In this study, we explored the actions of ephrin B1 in retinal Müller cells and their actions on inflammatory proteins. We used diabetic human and mouse samples, as well as Müller cells in culture to measure ephrin B1 in Müller cells. We then generated Müller cell specific ephrin B1 knockout mice. We measure levels of key inflammatory proteins, including high mobility group box 1 (HMGB1) and NOD-like receptor protein 3 (NLRP3) pathway proteins in retinal lysates from the ephrin B1 floxed and ephrin B1 Müller cell specific knockout mice. Data show that ephrin B1 is significantly increased in the retina of diabetic humans and mice, as well as in Müller cells grown in high glucose. Elimination of ephrin B1 in mouse Müller cells led to a significant decline in all inflammatory proteins studied. In conclusion, a reduction in ephrin B1 in the diabetic retina may offer a new therapeutic modality for diabetic retinopathy.
