摘要
Porpose: To determine the expression of mRNA coding for different N-methyl-d-aspartate receptor (NR) subunits in the human retina.Methods: In five human eyes the distribution of NR subunit mRNA was determined by in situ hybridization using 35S-labeled cRNA probes. In 100 consecutive retinal ganglion cells of each eye the level of mRNA expression of the different NR subunits was qualitatively graded. Results: Ninety-three percent of retinal ganglion cells expressed mRNA coding for NR1, 9% for NR2A, 28% for NR2B, 86% for NR2C, and 84% for NR2D. The pattern of expression did not vary among the five eyes.Conclusion: These data establish distinct expression profiles of NR subunits in human retinal ganglion cells and suggest the development of specific NR ligands to reduce excitotoxic retinal ganglion cell loss.
