In the article titled “Activation of Melanocortin Receptors MC1 and MC5 Attenuates Retinal Damage in Experimental Diabetic Retinopathy” [1], an error was identified in Figure 3 as raised on PubPeer [2]. Figure 3, BMS-470539 8 weeks, is the same as Figure 3, BMS-470539 16 weeks. The authors explained that this was due to a mistake during manuscript preparation and the corrected figure, as approved by the editorial board, is shown below.
