There is a significant genetic component in age-related macular degeneration (AMD). CX3CR1, which encodes the fractalkine (chemokine, CX3CL1) receptor, has two single nucleotide polymorphisms (SNPs): V249I and T280M. These SNPs are correlated with other aged-related diseases such as atherosclerosis. We have reported an association of CX3CR1 SNP and AMD. In this study we examined CX3CR1 SNP frequencies and protein expression on archived sections of AMD and normal eyes. We microdissected non-retinal, peripheral retinal and macular cells from archived slides of eyes of AMD patients and normal subjects. CX3CR1 SNP typing was conducted by PCR and restriction fragment length polymorphism analysis. CX3CR1 transcripts from retinal cells were also measured using RT-PCR. CX3CR1 protein expression was evaluated using avidin-biotin complex immunohistochemistry. We successfully extracted DNA from 32/40 AMD cases and 2/2 normal eyes. Among the 32 AMD cases, 18 had neovascular AMD and 14 had non-neovascular AMD. The M280 allele was detected in 19/64 (32 cases x2) with a frequency of 29.7%, which was significantly higher as compared to the frequency in the normal population (11.2%). We detected CX3CR1 expression in the various retinal cells. CX3CR1 transcript and protein levels were diminished in the macular lesions. This study successfully analyzed CX3CR1 SNP and transcript expression in microdissected cells from archived paraffin fixed slides. Our data suggest that the M280 allele, a SNP resulting in aberrant CX3CR1 and CX3CL1 interaction, as well as lowered expression of macular CX3CR1, may contribute to the development of AMD.
