Fig 9. Effect of MK801 on NMDA-induced loss of retinal neurons.

Fig 9

Whole retinas (panel A) or retinal cross sections (panels B and C) prepared 24 h after treating the eyes with PBS, PBS plus MK801, NMDA, and NMDA plus MK801 were immunostained with antibodies against Brn3a (panel A), Calretinin (panel B), and PKC-alpha (panel C), quantified by using Nikon elements AR software. Results presented in the figure indicate that NMDA promoted significant loss of Brn3a-positve RGCs, Calretinin-positive amacrine cells, and PKC-alpha-positive bipolar cells. *p<0.05. In contrast, treatment of eyes with NMDA along with MK801 significantly attenuated the degeneration of all three cell types. **p<0.05. NS, not significant.
