IL-4 receptors expressed on mouse RGCs. RGCs were labeled with RBPMS (green), and IL-4 receptors were labeled with an IL-4R antibody (red). First row: control group without IL-4 receptor antibody incubation; Row 2: IL-4 receptor was expressed in the RGC layer. The red fluorescence labeled IL-4 receptor coincided with the green fluorescence labeled RGC, suggesting that IL-4 receptors were expressed on RGCs
